Brainwavz S5 In Ear Headphones

This is a Review of Brainwavz S5 in-ear monitors. http://www.yourbrainwavz.com/s5.html

I was a little cautious approaching the review of the latest flagship in-ear model from Brainwavz. With a recent flood of quality in-ear headphones around $60-$70 price point, I wasn't sure how this $100 model going to stack up against other "giant killers". But after reading a few of the Head-fi reviews from people whose opinion I respect and value, I decided to give it a try. And I'm glad I did! To my very pleasant surprise, I discovered a sound signature that was a missing link among a growing collection of my headphones, and this latest offering from Brainwavz quickly escalated to the top of my favorite in-ears. I know that I have been saying this with a lot of my latest reviews and can't promise it will not continue because every headphone company offers their own unique tunning with their own interpretation of the sound, and based on our personal sound preference we keep listening and comparing to find the one which hits that sweet spot. Here is what I would like to share with you about my experience with S5 model.

Arrived in an excellent packaging, their box had the most detailed info I have seen in awhile. Everything from high definition raised 3D image to a very accurate description of the design and the sound characteristic, including list of accessories, specifications, and even detailed graphic representation of the internal design (under the magnetic flip cover) - all that showed how much pride Brainwavz took in showcasing their product which gets your attention even before your open the box. One detail that stood out to me was a flat cable design which supposed to go over the ear. I didn't have a good experience with flat cable design in the past, so was curious how it will work out. Out of the box, the all metal housing design with flat cables really stands out, where the first thing I noticed was an excellent strain relief implementation, but more about it later. In addition to S5 headphones, you will find a very high quality durable case which is so rare to see nowadays. So much effort goes into design of headphones with a plethora of eartips, but protection of headphones is often overlooked and instead we see a useless drawstring pouches offered with other headphones. Brainwavz earphone case is very roomy with a hard shell design and mesh pocket on each side which can hold headphones as well as small portable mp3 player. As a matter of fact due to a high demand Brainwavz sells this case as a separate accessory, and I'm glad it was included with S5. Inside of this case you will find a lot of included eartips with 6 pairs of S/M/L silicone tips (varying in bore diameter and stem length between 3 pairs), a set of bi-flange tips, another set of tri-flange tips, and a pair of medium size genuine Comply T400 foam tips. There is definitely plenty of options to find the perfect fit for sound isolation and sound fine-tuning. Also, there was 1/4" adapter and instruction manual with 24 months warranty card.

Now, regarding headphones itself. Though featuring a flat cable design, I was pleased to see a lot of heavy duty strain relief at every cable joint., starting with a straight 3.5mm gold plated jack and going to a meaty y-splitter. Believe it or not, they even included a chin-slider for this flat cable design, something I definitely haven't seen in the past. As mentioned before, connection to the earpiece shell also has a sturdy strain relief with L/R letter marking which unfortunately only visible under magnifying glass. Still, not a show stopper since earpieces don't have a symmetrical design and identifying left and right is easy. It did take me a little while to get used to it because in my mind flat cable design has to go wire down, so I had to break that habit. As a matter of fact, due to a nature of flat cable folding over the ear, it was easy to put earpieces in the right spot with pin hole air port facing inside. I'm not gonna lie, I didn't find the ergonomics of the design to have 100% like a glove fitment (it was a bit loose), but YMMV. One thing for sure, these S5 earphones have a very high quality build, and the fact Brainwavz offers 2 year warranty speaks of the confidence they have in the longevity of their product.

So how do these sound? VERY Addictive!!! Featuring a balanced sound signature with an enhanced bass, they are slightly v-shaped, but overall they have a smooth warm sound with just enough brightness to give it musical details. This unique balance between warmness and brightness is especially evident in upper mids where in the past I experienced either going one way or the way, but Brainwavz sound engineers found a perfect balance between warm/smooth and detailed/bright. Starting with a low end, it has a nice sub-bass extension with a warm texture, not overpowering in quantity but still with authority to be highly noticeable, and punchy mid-bass with a fast attack but not too aggressive. Low end is well controlled without spilling into mids. Mids are slightly recessed, clear and detailed, yet very smooth. Upper mids/vocals sound organic, with natural tones..Treble has a nice sparkle, not too bright, and I also felt it wasn't as extended with a sharp roll off. While listening for awhile, I didn't experience any ear fatigue. Soundstage had an average width and depth, and gave you enough space to get an intimate listening experience. It was very easy to drive from any of my DAPs and smartphone. I didn't find any problem with microphonics from their flat cable, but overall sound isolation was average, obviously better with Comply tips.

Since I'm often being asked after the review, how does it compares to other similar IEMs, I decided to add a few quick comparison notes:

S5 vs VSD3S: VSD3S mids sound thinner and brighter, sub-bass has a little more rumble and texture, while mid-bass is similar though a bit less aggressive, treble has a little more extension.

S5 vs RE400: RE400 has significantly less sub-bass/mid-bass quantity, sound is more neutral, vocals sound warmer and duller.

S5 vs KC06A: KC06A has less sub-bass but mid-bass punch is similar, even more aggressive, upper mids more upfront and brighter, less smoother, and overall sound a bit more aggressive.

S5 vs IM50: IM50 has more impact in mid-bass punch, it has smoother upper mids, warmer vocals, less detailed.


Overall, I was very impressed with a build quality, accessories, and unique sound signature which stands out without overlapping with my other in-ear headphones. There is a number of great balanced sound headphones offered in sub $100 category, and what makes them stand out is often how much bass enhancement they implement and direction of upper mids - toward warm or bright side. When it comes to these details, it's a matter of personal taste, and I can certainly say that Brainwavz hit a sweet spot for me with their S5 design. I wouldn't say it's 100% perfection since flat cable and fitment takes getting used to and I also found a slight driver flex with one of the earpieces. But in comparison to everything I liked about these IEMs, these short falls were negligible. I enjoyed S5 sound signature VERY MUCH and grateful to Brainwavz for giving me an opportunity to review their new headphones!

Here are the pictures.
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Brianwavz S5 are made really nicely with good materials throughout - they’re made of metal, but are not heavy, tips are secure, but not too difficult to change, the cable doesn’t seem in any way vulnerable to damage, and the plug is of good quality too. I like the look of the design very much too. The range of tips supplied should mean everyone has an option that fits.
 
They fit very comfortably, the edges are not sharp - the edges of some iems touch my ears and irritate, there’s no such issue with these. The angled flat cables are designed to go over the ears and stay there well with no discomfort - they feel quite secure in my ears. The anti-tangle function of flat cables works. Noise isolation is better than average - they’re good iems for wearing out. Cable noise is no worse than average, better than many, but is significantly lessened with a cable clip which is not included. Brainwavz could consider including one.
 
These iems are easy to drive, and don’t need an amp. I can enjoy them through an iPod, it drives them fine, but they sound better through my iBasso DX90 (everything does), perhaps because of the better DAC more so than the more powerful amp.
 
I settled on using the supplied Comply tips, they fit best for me of those supplied, maximise isolation, and for my ears they provide the flattest sound (most equal volume level across a frequency sweep).
 
I used these tools to ascertain the flatness of the volume level across frequencies:
 
http://www.phys.unsw.edu.au/jw/hearing.html
 
http://www.audionotch.com/app/tune/
 
I found that with my ears and Comply tips these iems are really very flat to the extremes of my hearing (my hearing drops off at 15,500kHz, and extends down to around 20Hz). There is a very mild and un-spikey rise at around 3-4kHz, which is a little more pronounced with tips other than Comply, and which sounds fine, it’s common to numerous good iems. Speakers that are regarded as providing a ‘natural’ sound often drop off in bass more than the S5s do, and so there is a question over whether the bass is a little too much to be considered subjectively flat. It doesn’t trouble me - it doesn’t get in the way of listening to acoustic music, I’m not troubled by the level of bass when listening to orchestral music, for instance. I can enjoy bassy music with them without feeling that I’m missing anything, and they do respond well to increasing or decreasing bass with equalisation.
 
Listening to acoustic music they present the tonality of instruments and voices in a very nice, naturalistic way. They can sound full and lush. I don’t find I’m focussed on details in listening to these, and perhaps the S5s are not the most detail oriented iems, but that is not to say that there is an impression that anything is missing - detail oriented iems often provide that detail by emphasising certain frequencies rather than actually reproducing more information - but it may be that there is less detail presented than the best, I’d say in bass texture for instance, perhaps I’ve heard better elsewhere, although I can happily listen to the textured bass of an organ recital without feeling that I’m being robbed of detail, so it’s not a big problem if at all.
 
The S5s present a reasonable soundstage, I’m not self conscious of the sound seeming in my head, but it doesn’t generally provide a startling illusion of space. Instruments seem located quite nicely, with some layering. Chesky’s binaural sound show sounds great, so they can do the job nicely. They don’t present sound at any distance if it’s not in the recording. Music that is quite forward sounds quite forward, and exciting at that.
 
The price of the S5s at about $100 is great. If I wanted a good all rounder iem at a reasonable price I don’t think I could recommend a better choice. Sure there are iems within the price of these that do specific things better - bigger soundstage, or more detail for instance, but all seem to have downsides too - for instance being hard to drive, poor isolation or comfort, mediocre construction and so on. And whilst there are others that do some things better, everything is done well enough by the S5s that I don’t feel at all that I’m missing out when listening to them. 
 
I think that Brainwavz are onto a serious winner with these, and I hope they do really well with them.

Review for the Brainwavz S5.
 
Firstly a big thanks to Audrey and Brainwavz for providing me the S5 for review. I am not affiliated or been financially compensated for the review except the earphones.
 
I was contacted by Audrey to review these and received a package very quickly after our communication on Headfi. The package was very simple but smart and had all the accessories and even a set of Complys which is a great inclusion. The hard case is a nice touch too as it provides someplace to tuck these away and the flat cable ensure they stay untangled.
 
These retail at $100 and the accessories and the build quality would rate it much higher. The expectations of an earphone in this heavily crowded market are very high and there is no shortage of competitors so what makes the S5 so special?
 
To start with the exterior, we have the nozzles which are at angle to the main body and surprisingly enough very comfortable and lightweight to stay in my ears. My Sony XBA-H3 sticks out like an eyesore and the S5 solves that problem very elegantly with its angled housing.
 
The wire as previously mentioned is a flat affair and great for day to day usage as it stays out of trouble and is usable straight out of your bag instead of the usual fidgeting around after putting a set of earphones in your pocket/bag/purse etc.
 
Lets jump to the sound quality now as see where the S5 stands in this fiercely contested market.
 
To start with the highs, the highs are very smooth with good extension and crunch but seem to limit themselves to that very last bit of detail and extension. Guitars are crunchy but could use just that little more crunch and extension. Mind you the average customer cares more about the bass more so that might not be as big a shortcoming for the average customer as I will elaborate further.
 
The mids are slightly recessed as the S5 seems to be aiming for a consumer oriented sound and while the mids are not thin or lacking in body, for their intended consumer they might just be perfect since the vocals are smooth and clear they are just mildly recessed and that is not a bad thing especially for electronica/trance/techno. I would rate them as easy listening and the mids simply flow but once again just need that bit more forwardness to be perfect and after experimenting with tips, they do change their sound signature for a slightly more forward midrange.
 
Coming to the bass its very punchy, very well defined and hits the right notes. A decent amount of texture and quantity makes it a very fun listen without being boomy or having a one note bass and having decent amplification makes the S5 shine even better in this area. My Arrow 4G would push the bass to stupid levels and the S5 would happily put up with it while the E12DIY controlled the whole scenario and gave the bass a bit more control and punch with its superior power. Overall this will easily satisfy bassheads provided they feed it well enough with a decent amp.
 
Overall I would recommend them at their price as they are pretty non-offensive in their sound signature especially for bassheads as they are very satisfying in that regard and really shine with an amplifier. Trance and other electronica are a pleasure to listen to as are drum and bass. They have a very warm presentation and I guess Brainwavz is aiming for the mass market and that’s not necessarily a bad thing.

P.S.
 
My review was late as I was waiting for some of my equipment to come back so I could listen to these earphones properly( I always have stuff coming and going to/from other headfiers) and in the meanwhile my two cats managed to get a hold of a couple of my earphones/headphones and chewed them out. The casualties included the S5 and my Fischer Audio FA-011.
I had to get a second pair to review these again just before finalizing and posting my review as it wouldn't be fair to Brainwavz to do a half cooked assessment. I don't write a lot but try to be thorough so heard them again and finally penned my thoughts.Apologies again to Audrey and the Brainwavz team.
 
Here are the furry culprits:
 

Disclaimer: I was sent a sample of the Brainwavz S5 for review. This will not affect my opinion of these IEMs in any way.
You can also find this review(with pictures) on my own blog here.
 
Brainwavz has been making cheap, well made IEMs that punch well above their weight for quite a while now. However I've never owned one before, so when I was approached to make a review I hastily accepted. Considering the price of the S5, and the increasing competition in this price bracket coming from some of the smaller Chinese companies lately, they offer an astoundingly complete package for their price.
 
Packaging and Accessories
 
The S5 come in a fancy book-style box that has been becoming more prolific recently among most tech products and it shows a nice attention to detail from Brainwavz. Large swathes of accessories have been becoming the norm from smaller Asian companies recently, and Brainwavz are no exception to this trend. The S5 comes with 6 sets of standard single flange tips(two sets of Small, Medium and Large, one grey one black), one set of double and triple flange tips respectively and a set of Comply T400 foamies, as well as a rather beefy(not in a bad way) 1/4 inch adapter and a rather snazzy carrying case. This is arguably my favourite part of the package as it is nicer than the one that came with my JVC FX800s that cost 2.5x what the S5 do. It's compact, rigid, zippered and has sorted compartments inside, perfect for carrying the IEMs with a selection of tips and other assorted things you might need on the go. Overall the packaging and accessories get the Brainwavz S5 off to a good start.
 
Design/Build Quality, Comfort and Isolation
 
The S5 are a traditional over-ear IEM: no surprises here. The housings are made of a nice shiny black metal with a simple Brainwavz logo the only adornment. The strain reliefs are adequate but not cumbersome or bulky and the cable is a tagliatelle style flat cable, sleeved in a grey rubber. It is light, and doesn't tangle easily. The Y Split is rather large, similar to that found on Shure IEMs and the cable cinch is also smooth and ergonomic. The jack is of the standard straight variety and strain reliefs on it and the Y Split are reinforced well, important on any IEM. The jack and split also have nice little engraved Brainwavz logos on them, which shows Brainwavz is putting the effort in when it comes to details, very nice to see. 
 
Fit wasn't an issue at all. The small housings and ergonomic shape of said housings makes comfort no problem, and the huge selection of tips provided makes getting a good seal easy, no matter the shape of your ears.  Isolation was very good with both the included sillicone and Comply foamies, able to withstand my daily commute on the train no problem, and as these are over the ear IEMs, microphonics were a non-issue. Build quality is, again, excellent. The metal housings, beefy strain reliefs at the jack and housings and strong y split make the S5 an incredibly well built IEM, especially for the modest price. They feel absolutely miles better than the similarly priced Audio Technica IM50, and I have absolutely no worries as to the longevity of these.

Sound
 
I usually listen to more electronic styles of music, but for this review I dug out some classical and rock songs to listen to in order to really get a feel for how these IEMs perform. I found no real difference when amped vs unamped, apart from maybe a little less hiss and noise, although this is mainly due to the fact that these are quite sensitive headphones, and so you'll want to use a cleaner source and decent quality source material otherwise you'll hear bad stuff you wouldn't normally hear.
 
One claim Brainwavz makes in their advertising is "Smooth Bass." While I was expecting this to be marketing drivel, it turned out that these do indeed have smooth bass. Bass is very well extended and deep, and texture is brilliant. Quantity is above neutral, but far from basshead level. It may sound muddy on the cleanest of recordings, but most electronic basslines and percussion, and bass guitars,  sound absolutely sublime. Bass is not as emphasized as the Audio Technica IM50, for example, but the extension and texture make it second to none. The low frequencies are my favourite part about this IEM.
 
The middle frequencies are where things start to slip a little. Mids aren't exactly recessed, per se, but they aren't at the forefront of the music either. They sound a little better than the IM50 or Yamaha EPH-100, for example, but they aren't going to beat any of the Shure offerings for example. Some Trance pads and Hardstyle leads sound decent, whereas others can sound a little overpowered at times, however the mids aren't necessarily bad. They are neither here nor there; neither at the front nor at the very back, somewhere in the middle, a little lacklustre but not an entire deal breaker.
 
Trebles are fantastic on the S5. They sound sparkling and prominent, and very well extended too. Sometimes on more bright recordings they have a tendency to sound a little too strident, bordering on fatiguing, but most of the time the trebles are clear and accentuated nicely. Listeners looking for a slightly more laid back, relaxed treble should look elsewhere, the treble here is bright and adds a nice sheen. Trance and Hardstyle leads stand out and sound rightfully epic, and violins sound just as they should, piercing and sharp but not painful. 
 
Another Brainwavz marketing claim is that the S5 boasts "Rich Detail." I surprisingly found this to be absolutely true. Detail retrieval is brilliant on the S5, and every layer of music can be easily picked apart even in the most hectic of climaxes. Soundstage is also very good on the S5, extremely wide for an IEM, sufficiently deep but not sounding spaced out or too wide. I played a lot of CS:GO using these and the combination of supreme detail, nice trebles, deep bass and wide soundstage made the experience top notch.
 
Conclusion
 
The Brainwavz S5 present a brilliantly rounded package at a very competitive price point. They are built well and come with any accessory you may ever need, fit and isolate well, and sound good with most types of music. Users who listen to unusually mid-heavy genres(unplugged vocals, types of Jazz, etc) may want to look elsewhere, but for everything else, the Brainwavz S5 provides an excellent listening experience.
 

Hello, my name is Justin and this is my second review on here! Hopefully many more will come as I practice writing and getting new gear. 
 
First off I'd like to thank Pandora @ Brainwavz again for allowing me to review this superb IEM. I gave them a solid 100 hour burn in after an initial listening session, I honestly didn't notice much change besides the bass coming out to play, treble opening up a bit. 
 
About Me: I prefer IEMs over full size because of portability and comfort, though I have owned and own a few full size cans. I am a 28 year old music lover, i listen to all genres from R&B to Rap, to Rock/Heavy Metal, to Jazz, Oldies, Country, Blues, etc. If its music I will give it a listen!

Build: 
 
Like I said, its solid. The strain reliefs have give but appear to be made of a thick rubber. I don't see them tearing anytime soon. This is good for my friend who I gave these to. He caught the SM E80 in his desk drawer which ripped the cable from the housing. The flat cable is comfortable over ear. The isolation is superb. You can barely hear anything going on externally even at a low volume. I did choose to use tips from my Puro IEM500. The housings are a tad big but are lightweight. I even used these out on a walk a few times and it was perfectly fine
 
Sound:
 

1. Bass: The bass came out to play with burn in. Still it was neutral and did lack sometimes in electronic music BUT due to this it was a very pleasant relaxing listen and was able to allow the single driver to showcase the other frequencies with easy instead of being congested and muddy. Its fast and has a good punch
2. Mids: While being a balanced, almost neutral IEM the mids really shine. They are not forward nor recessed. They have a ton of detail. They have a good enough amount of air that music is a joy to listen to. 
3. Highs: They are detailed and crisp without being too bright. I'm treble sensitive and they are non-tatiguing

 
The overall sound for me was, as stated, very pleasant. The only con I could see is they lack a bit of sub bass rumble and give some energy to electronic & hip hop but if you take them for what they are designed to be, a balanced and fairly neutral IEM then you should have no qualms.

 

 
This is my first Brainwavz earphones, many thanks to Brainwavz for the review sample!
 
When I wrote this review, I have used it for almost 2 weeks, around 2 hours daily. A happy ending journey, that was started with a not so happy beginning.
 
Out of the box, first impression, S5 sounded bright to me. Rather too bright for my liking. Owning some other bright headphones and earphones, I thought S5 is tuned as a clear and bright sounding IEM. Then i let it burn-in for about 2 days.
 
After 2 days burn-in, i didn't hear any improvement, basically still bright sounding. 'V' shape sounding that is more like a checkmark '✓ ' shape, where the treble boost around 5-7 kHz is much more pronounced than the bass boost. I brought it to office, to let a friend of mine who is a sound engineer, to try it. After a few hours with S5, same impression, S5 was too bright for him as well. I started to wonders, as some other reviewers here didn't hear S5 as bright earphones.
http://www.head-fi.org/t/725340/brainwavz-s5-iem-headphones-review/330#post_10735721
 
The next day, i tried different eartips. First, the tri-flanges.  Wow wow wow!  I was really surprised with the changes. The S5 now sounds very balanced, not bright anymore. I let my friend tried it again; he thought i gave him a different set of earphones. We were really surprised with the changes.
 
Curious with the drastic changes, i tried back the stock grey tips, and no more excessive treble...! What was wrong initially??? We did feel proper seal, and the slightly boosted bass confirming that it wasn't seal problem. but initially the treble was too much. After eartips replacement, the sound became balanced, and i couldn't reproduce the bright sound character anymore. Was it because the grey eartips were not properly fitted from the factory, or S5 suddenly changed its tonal balance after around 3 days of burn-in and use?  I'm not sure what was the cause of the 4-5 dB excessive treble initially, and what caused the sudden changed of the treble level. It remains a mystery to me and my friend.
 
From a review by [color=rgb(34, 34, 156)]shotgunshane[/color] here:
http://www.head-fi.org/products/brainwavz-s5-in-ear-headphones/reviews/11349 
I have the impression that his S5 is also the bright sounding one, and still bright sounding.  While my S5 has changed its tonality becoming a more balanced sounding IEM.
 
From my experience, if it happens that you feel your S5 is bright sounding, I suggest the following:
1. Try different eartips.
2. Continuous burn-In for around 3-4 days.
 
Now, with all the supplied eartips, S5 sound signature is relatively balanced, only slightly bright. Best sound achieved with the tri-flanges, which sound SO MUCH better than other eartips. I've read many other reviews of Brainwavz S5, and some impressions are varied quite significantly. So 'Your Millage Might Vary'. To be fair to Brainwavz, my evaluation in this review will be based on the best performance the S5 can achieve during the evaluation period.
 
 
 

 
 
Summary (based on Tri-flanges eartips)

Balanced & transparent is the best way to describe Brainwavz S5 tonality. Brainwavz S5 is neither warm sounding, nor analytical. Tonality sounds quite natural, slightly V shape, in between warm and analytical, lean slightly to the analytical side. I don't hear any annoying peaks and dips on the tonality, pretty smooth from bass to treble. Bass has good power and punch, mids and treble are clean, clear, and transparent.  Detail and clarity are good, no veil at all, music always sound clear and detailed, although S5 is not yet into the level of ultra-revealing IEM. 
 
With tri-flanges eartips, imaging is quite wide and spacious. Almost at the level of ATH-IM02 wide and spacious imaging. With other eartips, imaging is not as spacious, but still reasonably spacious and never sound congested.
 
Tri-flanges eartip is the absolute necessity to get the highest level of sound quality from S5.
 
Though relatively easy to drive, S5 does require gear matching to sounds best, and scales up pretty well with good sources.
 
In summary, Brainwavz S5 strikes a good balanced in tonality, and has very good dynamic, detail, and imaging. A balanced, transparent, and musical sounding earphones, that is simply an excellent all-rounder in its class.
 
 
Performance score for sub $100 IEM category:
4.5 stars out of 5 stars at its best performance, with the tri-flanges eartips and matching players.
3.5 stars out of 5 stars at its worst performance.
 
 
 
Equipment
 
 

 
Centrance DACport: DAC + HeadAmp combo. Very organic and musical sounding. very smooth sounding treble, pretty close to AD8599. Always match very well with bright or analytical sounding earphones & headphones.
Audioquest Dragonfly v1.0c: DAC + HeadAmp combo. Marvelous little DAC. Transparent, airy, and powerful. Slightly lean to analytical sounding.
Light Harmonic Geek Out 450 v10.02: DAC + HeadAmp combo. Newest mini DAC in my arsenal, very powerful and detailed sounding. Sound signature is closer to the Dragonfly than to DACport. Lean a little bit to sterile sounding.
iBasso DX90: Portable player. Natural sounding, not warm and not analytical. Good dynamic, detail and resolution.
Fiio X5: Portable player. Natural warm, very smooth & musical. Sounds a tad warmer than DX90. Good dynamic, detail and resolution.
Fiio X3: Portable player. Powerful, balanced sounding with good bass and sparkling treble.
 
 
 
Sound Signature (using Tri-flanges eartips & AudioQuest Dragonfly 1.0c)
 
S5 Clarity and detail are very good, although not yet at the level of highly revealing IEM. Clarity and transparency varies significantly between players and DACs, best transparency I heard is from AudioQuest Dragonfly. But even with the lowest transparency setup, clarity and detail are not lacking. I do prefer more detail when listening to Chesky binaural recordings, so Dragonfly will be my DAC of choice. But for other close miked modern recordings, I might pair it with warmer sounding DAC such as the DACport. As a single dynamic driver, S5 clarity and detail is better than my ATH-IM50 and ATH-IM70. That is a very good achievement from a single dynamic driver. Paired with Dragonfly, detail and clarity almost reaching the level of detail & clarity of BA drivers IEMs such as ATH-IM02 or DUNU DN-1000.  I consider the level of detail and clarity of S5 are excellent at this price category.
 
Imaging is wide and spacious, sounds more spacious than ATH-IM50, ATH-IM70, and TDK IE800. But not as spacious as ATH-IM02, DUNU DN-1000, and DUNU DN-2000. Especially using the tri-flanges, imaging and spaciousness are pretty awesome. Although other eatips don't sound as spacious, S5 never sounds congested.
 
S5 has very good dynamic to make music sounds realistic. Better than TDK IE800 and Fostex TE-05 dynamic, but not yet at the level of ATH-CKR9 dynamic. Listening to 'Mombasa', movie soundtrack from Inception, I heard much better bass impact and dynamic on S5 than TE-05. About the same level of dynamic as UE TF10, and only slightly less when compared to ATH-IM50 and ATH-IM70. When it comes to dynamic it's hard to beat the dual dynamic drivers IEMs from Audio Technica, such as the IM50, IM70, CKR9, and CKR10 that I've reviewed earlier. But having said that, the single dynamic in S5 is no slouch either, and could deliver pretty good level of dynamic.

Bass is slightly on the upper side of what often perceived as neutral. To me this is the bass level that I like, realistic bass, not bland and boring bass. I don't like bass level that is lower than S5 bass level. Bass has pretty good power and punch, but not extraordinary tight and punchy. Bass doesn't colour the midrange and nicely blends with the mids. S5 is not considered as a bassy IEM. Bass level is not as strong as ATH-IM50 and ATH-IM70 bass. Bass lover may better go with ATH-IM50 and ATH-IM70. S5 bass is more or less pretty close to UE TF10 bass level, but bass emphasis is on different area. TF10 emphasizes more on mid-bass, S5 more on bass to low bass area. S5 low bass extension is very good. I tested using my 20Hz - 60Hz Risset-Drum beats I created using Audacity, S5 performs flawlessly. Clean and clear down to 20 Hz. Very good quality bass.
 
Midrange is smooth and clear. Slightly on the lean side of natural, vocal sounds smooth and clear, instead of warm and full bodied. When we are used to IEM with warm and full bodied mids, S5 midrange might sounds a little recessed. But those from the analytical side might consider S5 mids level quite natural. The good thing is, the mids sounds quite smooth & natural, without any annoying peaks and dips on its spectrum. And that is very important. I won't bother to review and spend my time on any IEM with highly coloured midrange. Smooth and relatively natural sounding midrange is the first criteria for me to choose an IEM, and S5 pass with pretty good result.
 
Treble is sparkling rich, with very good transparency. I use classical music to evaluate transparency, and usually avoid any IEM that is lacking in transparency for classical music. S5 transparency is excellent for classical music. Enough air and upper treble extension for classical music to be enjoyable. S5 transparency is better than TDK IE800, ATH-IM50 and ATH-IM70, but may not as transparent as ATH-IM02. Somewhere in between, pretty close to ATH-IM02. Tri-flanges eartips greatly improves S5 transparency and clarity, better than other eartips.
 
Probably one of the most important topic for treble is sibilance. For those who have Celine Dion album 'All the Way...A Decade of Song', might agree that the mix is quite bright, and better played using slightly dark and warm sounding IEM. Surprisingly, S5 with the tri-flanges, while still renders the transparency of the mix quite well, also manage the high level of treble really well without sounding ear-piercing. Only mild sibilance with 'vibrant treble' recordings. Amazing! But expect higher level of sibilance with other eartips.
After the treble metamorphosis mentioned earlier, S5 treble is more towards the silky smooth type of treble rather than the metallic and ear-piercing type. With tri-flanges eartips, S5 treble always clear and transparent with excellent sibilance management.
 
Comfort and noise isolation:
Comfort is good from my perspective. I always wear it over the ears, although it is possible to wear them straight down. I don't find any comfort issue so far, though I think round cable is nicer than the rather big flat cable. Cable microphonics is minimum when worn over the ears.
Most of the time I use tri-flanges eatips with no comfort issue.
Noise isolation is very good, better than average I would say. Maybe also due to the tri-flanges eartips that I use.
 
 
 
Gears and Music selection

Brainwavz S5 is generally a good all-rounder, pretty good performer from classical to modern genres recordings. But players or sources also play a great role here. With Light Harmonic Geek Out 450 and Centrance DACport for example, I have better impressions with modern genres recordings, especially those close miked recordings, like for pops, my Stockfisch albums, and other guitar-oriented recordings. With those DACs, Acoustic guitar sounds naturally sparkling and detailed without getting to the level of fatiguing. Simply beautiful. But with those DACs, S5 might not transparent enough for classical and binaural recordings (at least for my preferences). Paired with AudioQuest Dragonfly, S5 sounds clearer and more transparent, maybe a bit too clear for pop albums, but much better for binaural recordings like the Chesky binaural albums, and classical recordings. So I mix and match the DACs and the recordings, to get the most optimum sonic performance from Brainwavz S5. When gears and recording properly match, sonic performance is nothing short of amazing. I have the tendency to use S5 more for orchestral works and binaural recordings, I like the transparency and the immersive 3D imaging properties of S5, especially when using tri-flanges and AudioQuest Dragonfly.
 
From the 3 DACs I used in this review, Dragonfly is my favorite for Brainwavz S5. Open and spacious sounding, with immersive 3D imaging. The level of 3D imaging on this setup is quite remarkable, almost unbelievable from a $99.9 IEM. From memory, this 3D imaging is pretty close to ATH-IM02.  I bought my Dragonfly 1.0c from Amazon for $99, so this is simply one of the best 3D imaging performance I could get from a $200 setup. Amazing!
 
 

 
With the DAPs, I found Fiio X3 and iBasso DX90 have good synergy with Brainwavz S5. I vote for Fiio X3 + Brainwavz S5 (using the Tri-flanges) to be one of the best $300 portable setup, especially for those looking for natural, lively, clear and transparent sound signature.
 
 

 
 
 
Eartips
 
 

From my experience and observation, eartips play a great role in IEM sound quality. It is absolutely necessary to find the right eartips that sound best and give maximum comfort. Brainwavz S5 has 4.5 mm nozzle neck diameter. Quite a standard size for generic eartips replacement.
Understand that tri-flanges tip is quite big and long, and might not fit everyone ear canal, so impressions with other eartips are also important. Comparisons below is using the tri-flanges as the reference.
 
 
Tri-flanges
Ultimate best sound quality for Brainwavz S5. It brings S5 sound quality above Fostex TE-05 and TDK IE800. Detail and clarity exceed ATH-IM50 and ATH-IM70. S5 sound quality leaps up with the tri-flanges, as compared to other eartips in the package.
 
 

 
Bi-flanges
Tonality not so much different than tri-flanges, but the upper treble extension and low bass extension are not as extended as the tri-flanges. Overall tonality is less airy and imaging is less spacious, a bit congested as compared to the tri-flanges. The bi-flanges also slightly more prone to sibilance
 
 

 
Mono-flange grey
Like the bi-flanges, the stock grey eartips also have less lower bass and upper treble extension, less airy, and less spacious, lacking of depth. Not only that, the level of detail and clarity also reduce, especially midrange detail, and even more prone to sibilance than the bi-flanges. Bi-flanges is slightly better than the grey eartips.
 
 

 
Mono-flange black
IMHO the black tips sounds worse than the rest. Tonality is less natural, midrange a bit veiled, and then suddenly the treble peaks that makes the black tips the most sibilant eartips.
 
 

 
Comply T-400
Foam tips usually have good properties to manage sibilance. But with S5, T-400 has higher level of sibilance than the tri-flanges, about the same level as the grey tips. Also lacking of spaciousness and depth. Bass level is the lowest on T-400. I still prefer the grey tips as compared to the T-400.
 
 

 
 
Comparisons
 
 

 
For this comparison, I used AudioQuest Dragonfly DAC v1.0c. Low output impedance headphone output from the Dragonfly is required especially for UE TF10. TF10 hates high output impedance output, it makes TF10 sounds muddy and lacking in clarity.
 
Ultimate Ears TripleFi 10 (stock eartips)
S5 sound rather V shape when compared to UE TF10. UE TF 10 has better and fuller midrange body. As expected, TF10 vocal sounds fuller and slightly warmer. Although less full bodied, I don't consider S5 midrange as recessed. S5 mids still sounds natural, but on the leaner side of natural. S5 with the tri-flanges has airier presentation than TF10, which is slightly better for classical orchestra.
TF10 has more and punchier mid-bass, but not too much different. While low bass extension is about the same, slightly better on S5. As mentioned before, for bass, TF10 emphasizes more on mid-bass, S5 more on bass to low bass area.
Clarity, about the same for S5 with tri-flanges. When using the grey tips, TF10 has better clarity.
Treble level and quality is about the same level. Slightly better and more transparent treble on S5, when using tri-flanges eartips.
Overall sound quality of the S5 with tri-flanges eartips is not far behind TF10. Only different character, mainly on the level of midrange. But S5 sound performance decreases with different eartips. 
Personal preference: I like both equally.
 
Fostex TE-05 (stock eartips)
TE-05 has smoother midrange, but that's about it. Everything else S5 sounds better to my ears. Bass is much better on S5, more powerful with better texture & dynamic. Midrange is smoother and slightly fuller on TE-05, while S5 has clearer and more transparent mids. S5 with tri-flanges has better treble clarity and upper treble extension, sounds more open and transparent. TE-05 treble is slightly softer, less bright. TE-05 has poor noise isolation, S5 noise isolation is much better. But what S5 excels most comparing to TE-05 is the dynamic. I hear much better dynamic on S5, much wider range of dynamic from soft to louder part of the recording. Overall, music sounds more realistic on S5. I guess I haven't found the right eartips for TE-05. TE-05 does benefit from S5 tri-flanges eartips, improve isolation and dynamic, but the tonality not so good with the tri-flanges, too much mids. At least with its standard stock eartips, TE-05 doesn't sound better than S5.
Personal preference: Brainwavz S5.
 
Audio Technica ATH-IM70 (stock eartips)
IM70 has bigger bass (not much), thicker mids, and softer treble, less clarity. S5 sounds clearer and more transparent, better upper treble extension. In this comparison, I think S5 sounds closer to natural sound. S5 also sounds more spacious than IM70. Between the 2, my general sonic preferences is actually closer to the S5 sonic character, more spacious, open and transparent sound. But depending on the recordings. Those looking for warm and intimate sounding vocal would probably prefer the IM70. Both are really good in their own way.
Personal preference: I like both equally, for different type of recordings.
 
TDK IE800 (RHA eartips, larger bore to improve clarity)
S5 sounds more open, spacious, and transparent than TDK IE800. Switching from IE800 to S5, the S5 sounds rather bright. The other way around, once I get used to S5, switching to IE800 I feel IE800 is lacking in clarity and transparency. In fact they just have different level of treble, around 4 dB difference around 7 kHz onward. IE800 overall sounds smoother, more refined, with fuller midrange. S5 sounds clearer, more transparent, more spacious sounding, and a bit more lively. S5 has better bass than IE800, better level, better low bass extension, and better dynamic. S5 also sounds more lively with better dynamic, while IE800 sounds a bit compressed in comparison. IE800 requires much higher voltage to drive it, and S5 is easier to drive. This is important for smartphone that has low voltage swing. For me, I tend to like the S5 lively, open and transparent sounds better. But that's just my personal preference since I listen a lot to classical. For some 'rather bright' recordings, IE800 might be a better choice.
Personal preference: Brainwavz S5.
 
 
 
Pros:
Very nice blend of balanced tonality, transparency, detail, and dynamic.
No Driver Flex.
Various eartips included for flexible sound tuning and maximum comfort.
 
Cons:
Requires the tri-flanges eartips to sound best, which might not suit smaller ear canals.
Left and Right marking is too small and not clear. No left dot / dimple to identify the left driver in dimly lit environment.
The rounded back housing shape makes it a bit difficult to push the IEM into the ear canal while pulling ear's pinna with one hand.
 
 

 
 
Suggestion for improvement:
Bass punch and tightness.
Slightly warmer mids would be nice.
To achieve the sound quality as when using the tri-flanges eartips, with the regular mono-flange eartips.
To include more sizes of the tri-flanges eartips.
Round shape cable seems more user friendly for over the ear wearing style.
Clearer Left and Right marking, and to include Left dot / dimple for easy identification in dimly lit environment.
Flat back housing (like Brainwavz S1) for easier insertion to the ear canal.
 
 
 
I'm glad I found another reference IEM at this price level.  This IEM is definitely a keeper for me, and I will use it as one of my reference IEM for my future reviews.
Congrats to Brainwavz!

Recordings mostly used in this review:
 
 

  I want to start by saying thanks to Brainwavz for making this nearly excellent phone and  Selsera for sending me a sample unit .
 
  And about Brainwavz , its around for nearly 7-8 years and has a good reputation of making " bang for buck " phones .
 
  Brainwavz has recently launched the " s5 " which is currently retailing for $99.50 in the us and just below 60 pound in uk . It comes with a plethora of tips , 9 to be precise , one comply , two tri flange tips (small and large ) and 6 pairs of single flange tips in 3 different sizes with two color scheme , comes with a nice carry case and has a quarter inch adapter too . a nice package but i think the box could have been smaller , not a thing to bother about though , just a thought .
 
   here are the specs from mp4nation :-
     
   
 
 
 
 
 
  
  Specifications:

1. Transducers/Drivers: Dynamic, 10mm
2. Rated Impedance: 16ohms Closed Dynamic         ( can be driven from you device , no need to amp , you can , but not necessary )
3. Sensitivity: 110dB at 1mW                                  ( high enough )
4. Frequency range: 18Hz ~ 24kHz                         ( good enough , we average people cant hear under 20 hz and over 20k )
5. Distortion: <= 0.3% @ 110dB ( adequate )
6. Channel balance: =< 1dB (at 1000Hz)                  ( 1db is pleasantly negotiable )
7. Rated input power: 20mW                                   ( low but its what you get for most of the earphones )
8. Maximum input power: 40mW
9. Plug: 3.5 mm 45-degree gold plated                     (  not 45 degree at all , its 180 degree )
10. Cable length: 1.3 meters Y cord (CU/Ag) PUR      ( long enough and i like it )
11. 1 year warranty
12. Dimensions (Packaging): 160 x 135 x 38mm        ( could be smaller )
13. Net Weight: 10g
14. Gross Weight: 140g

 
  Build and misc :-
 
 
 
 
  So , it has a dynamic 10 mm driver to use , has an impedance rating of 16 ohm and can be driven directly from your mobile phone or your DAP too .
  The driver is placed in a all metal housing , which makes it a bit heavier but its not a problem . the cable is flat , as flat as it gets  , but you can see the one in the diagram is round , all i want to say is , it could have been a bit narrower and a bit thicker maybe , round would have been best but the " S " series has flat cable so we are not gonna get that in this series , has a chin/cable slider too , comes with no cable clip so i added one of mine . And the cable has very low microphonics when worn over ear , has little when cable down . Wait what ? you though its a " only over the ears design " ? no , you can go cable down too .
  and about the L/R marking look for the brainwavz , written on the earpiece . can you see the " R " ? its not that easy , but you can see brainwavz , and it goes in just like this , doesnt matter if its over ear or cable down .
   
   
 
 
   
 
   A straight plug with rigid stress relievers is not a thing i want , i like 90 degree ones that can easily go into the pocket without damage the cable , i have seen the cable taking some stress but im not sure how much it can take . the " Y " splitter is on the bigger side , i used to think er-4p has the biggest of these but this is close .
 
   enough of this , lets go for what you are here for .
 
  Sound quality :-                                  ( vs re-400 )
 
   When i first put these in , i liked these instantly . but the bass was boomy , then i burnt it to realize that highs too has lost some spark somewhere in this process , and after 150 hrs , highs are good but lacks the spark that used to be there , but more then that , bass go tighter , not tight enough but its okay now . and now after 200 hrs of burning i am here to talk about the sound .
   ( i am using clear philips hybrid tips on re-400 and S5 )
   i was having a hard time getting a good seal with smaller tips or the tri flange tips , so i used the black large or the comply , and in the end i went for philips tips cuz it was bigger and has equal or better clarity then s5 large black tips . never bothered to try the grey ones cuz the word has it that they make S5 lose clarity .
 
   You can see in the pros , clarity is really nice , my only grief is the bass decay .
 
   Before i start , lets me tell you about my sound preferences , i like bass , but fast and deep , go boom and vanish , not a fan of mid bass hump , mids , instruments , vocals and separation , the clearer that better , highs with some spark , spectrum as flat as it can get . not a fan of V-shaped sound but i can do that . A good sound stage is pleasing too . and should be easy to get a fit .
 
   Lets start with lows :- ( i mean bass )
    you can see in the cons , s5 lacks some speed when it comes to bass decay , it could have been and i believe it will be tighter when the to be made " S9 " breaks cover . and i think it is because of a mid bass hump . Bass got resolution , and the slam that keep a bass seeker satisfied . Bass is big enough if not huge and hits hard enough too , not like xb90ex which goes boom with a hint of bass and hits like a brick with bigger amount of air at the same time . S5 is no bass monster but can do the job if you are willing to settle for something less .
 one good thing is that bass doesnt over whelm the mids . And has more presence and quantity when compared to re-400 .
 And this suits the new era pop music , and will appeal to new generation of party goers .
 Against re-400 , S5 lacks precision and speed . S5 on the other hand has more amount of bass , more air , more slam and this is what makes it more enjoyable . From a purist perspective , re-400 wins , but for a everyday casual listening that lasts for 10s of hours and longer , S5 all the way .
 
  Mids and sound miscs :-
    so the first thing you can feel here against re-400 is , 400 has some veiling in the mids , a bit grainy , vocals seem a bit low , but S5 has nothing like that , if the slight u shape is forgiven ( which make the mids to take a seat behind ) , its far better then most of the phones in this department and better then re-400 too . Then , re-400 has a hair more details to it , more detail to the instruments , and its upper mid prominence helps in this , S5 on the other hand is too close to distinguish but with songs like " superhero in a ball " you can feel re-400 pumping some more clarity with instruments , S5 on the other hand is not that forward in this department .
   on vocal front , i will have to say , even if female vocals are not as good as male vocals with S5 ( really close though ) , S5 has better clarity when compared to re-400 . re-400 prefers female vocals and due to that veiling vocals suffer .
   Instruments on the other hand are really separable with both the phones , but S5 has an edge over re-400 , with its presentation being more vivid and a bit more space when it comes to sound-stage , S5 out does the re4-00 . so the winner is S5 . keep in mind that these are not V-shaped , slight dip , but not much .
 
  Highs at last :-
    This is where re-400 does some serious damage to the S5 , S5 got clarity , got transparency , smoother , easy on ears , not offensive at all , sibilance is out of question and still has good amount of presence and details . re-400 does all the things above and adds some more spark , got more energy and is more reveling too , has the attack that i like , but you have have to keep in mind that this might get a bit offensive or a bit annoying on a longer run , and if you are a fan of smoother highs , S5 is made for you . S5 had some spark initially but lost that with burning and reduced to more like a splash . no complains at all , its just that i prefer some spark , more energy and attack with my highs . Extension is a question for s5 , but re-400 has better extension .
 
  So its re-400 vs S5 now , 400 has better sonic ability , has better extension , but that veiling at mid is a let down for some .
 so , its a draw , but i like the re-400 more , cuz its smaller , has better stress relievers , has an angled jack too and suits more to my preference . if , just if , S5 had tighter bass , i would have given it the bragging rights . its a call too close , and i would love to see a brainwavz phone with a tuning to out do the re-400 .
  re-400 is not a phone for the crowd , its like more analytical , its more for purists , its not as enjoyable as S5 is . and this is just where S5 comes in with similar clarity and at the same time brings more fun to the table .
   And to me S5 feels cold , its like , dull in front of re-400 , its kind of laid back , not forward enough , not warm enough , and has 5% lesser details . YES !! S5 is more fun , but , i like my re-400 more .
 
  Conclusion :-
    Its a super solid phone , with a few small flaws , built is really nice , ability to take any eq is spectacular . Got an enjoyable sound sig , a really good package . nothing to hate and everything to love for . And if ..
    if you are looking for a phone that is smooth , has really nice clarity , got crowd pleasing bass , i will say fabulous mids with no real flaws if not as reveling as top end ciem , with pleasing inoffensive highs , a phone that you can listen to all day long , with no fatigue at all and sibilance is no where to be found ..
   " Brainwavz S5 " is made for you . highly RECOMMENDED , even over the re-400 .
 
   
    ( she3900 grey tips )
 
  
 
   Some improvements i would love to see :-
    1. i want the bass to be tighter . no problem with the slam or air or anything at all but speed .
    2. add a cable clip please .
    3. a better cable if possible will do wonders .
    4. add some spark if possible , to the highs .
 
   thats it , have a beautiful day folks , enjoy your music .

Design and Comfort
S5 is a new higher-end in-ear-monitor from Brainwavz retailing at about US$100.  I’m glad Brainwavz has offerings at most price points below $200. It's great that companies such Brainwavz and SoundMagic help bring down prices; if not for them, we would still be paying an arm and a leg for these things.
 
It has a flat cable instead of the normal round cable, similar to the new Creative Aurvana Live! 2. I don’t know if this is a trend. I’m more used to round cables, but round cables do tangle a bit, except really thick ones like the ones used on HM5, so I think flat cables do have an advantage here if you want your cable to tangle less.  Microphonics is minimal, slightly more than Brainwavz M4; however, that can easily be solved sliding up the cable cinch (e.g. during exercise).
 
The IEM’s housing has a flat side, which comes in handy - a tactile way of identifying left and right earpieces. All you have to do is have the flat side facing outward when worn. The letter “R” and “L” are extremely small, but you just need to look at them once and you’ll remember which side is which by looking for the flat surface on one side of the housing. Isolation is excellent, at least 25dB, basically similar to earplugs. If you’re looking for an IEM that isolates noise like an earplug, this is an good option for you.
 
It came with an assortment of different standard silicone tips, including a set of very nice Comply T-400 foam tips. I’m using the T-400 for this review, while I use S-400 on my M4. I’m a fan of Comply tips, and I prefer foam tips to silicone tips in terms of comfort and sound. Silicone tips do, however, bring out better highs on most IEMs (if not all), if that’s what you’re after.
 
It’s very easy to drive, coming from relatively easy to drive headphones. It’s louder than M4 at the same volume for example.
 
Sound Quality
Straight out of the box, I couldn't really fault it much. I’ve done over 150 hours of burn-in. DAC is FiiO E10. There are some similarity to Brainwavz M4, could be considered an upgrade in every way, except I prefer M4's mids.
 
Bass is deep and tight, probably a tad more than what you call neutral/flat, not unlike CAL!2. It's perfect for people who like to feel their low notes.  I don’t find the bass to be distracting; in fact, I can really appreciate the detail in the bass. Unlike M4, you won’t find a mid-bass hump in S5.
 
Midrange is slightly warmish, without any bloated mid-bass. If I had to complain, this would probably be the weakest link of S5. You're not going to get perfect sound at any price, let alone at this price range.
S5 is less airy than M4. That’s expected of something that blocks 90% of all ambient noise. For me, I do prefer my mids to be more airy, so I’m biased. I guess that’s the trade-off between isolation and soundstage. 
 
Treble is very smooth with the foam tips. No sibilance at all, but detailed enough to show it if the recording has it. With silicone tips, the sparkles are brought out, more so with the the tri-flanges.
 
While soundstage is quite intimate, I feel like I’m listening to music in a studio environment.  Due to its excellent imaging, some recordings sound a bit binaural. I thought was sitting next to the pianist, facing the other way (away from the piano). Classical and country sound so good, especially piano pieces.
 
Conclusion
This is a very likeable IEM for mainstrem music-lovers, regardless of your preferred sound signature, in my opinion.  Is it for bassheads? Sure, if you like quality bass with enough quantity but not overly so.  Is this for treble-heads? I reckon B2 is a better choice. The sub-$100 bracket is such a competitive price range, these days you can get headphones or earphones that would have cost you several times more in the past. If you were to buy just one IEM for portable use, this would be my personal choice for portability. It's good at most things, and excels at sub-bass.

Rather than go into the esoteric aspects of the sound signature (not really sure if all the nomenclature actually means the same thing to everyone) I'm going to approach this review from a little more practical (everyday use and listening) aspect. Also I won't add any photos as they are in almost all the other S5 reviews and it would be redundant. This will be rather brief and to the point.
 
First things first. The usual great packaging and accessories selection that Brainwavz is known for. Decided to do most of the review with the installed tips as they fit and sealed well for me. These have a wonderful sturdy build. Just first rate. I would like more IEM makers to maybe put a little bit of red or something on the right strain relief (or cord) to make it easier to know which way they should be inserted. Of course this isn't necessary for overear 'phones like these as they usually insert just one way but for noobies to overear 'phones it would be helpful I think. The flat rubbery cord is likely an either love it or hate it kind of deal. I actually quite liked it for lack of tangles and how well it stayed in place while running, etc.. 
 
Out of the box the bass was definitely noticeable. Possibly because few IEM's delve into the lower registers this well...but it's a little jarring at first. After some burn in (and brain burn in) the sound (especially the bass) mellowed and really grew on me. Shortly after I started really listening to these and while going through my usual audition list I had the occasion to attend several live concerts in my area. That's when it sort of "clicked" for me. What these 'phones do really well, and what many of my other IEM's are missing, IS the lower register that makes for the "live" sound you would hear seeing an artist in person. But I did have to turn off any and all bass boost on my DAP's and amps because the bass was already so present with these.
 
I can't vouch for how well they do on electronic music (EDM or dubstep or whatever) but on real musical instruments and voices they are very very good. I do think they lack just a tiny bit of upper register harmonics, perhaps certain things like on a high hat cymbal or guitar strings or maybe what many would call "air" but it's very little that is lacking.
 
The midrange is quite lush and smooth. I mentioned in the S5 thread that I thought these would make good inexpensive stage monitors for vocalists and I stand by that assertion. Many of the things I try to hear in my own voice as an amateur singer/musician are things that these reproduce very well. On many tracks it feels like you are right there with the vocalist singing directly to you. Very involving and intimate. 
 
Soundstage is very good for this price range comparing well to most others in width and surpassing them in depth a little bit. 
 
Now to the more practical. I'm an avid runner/gym rat and am always looking for better sound during my workouts. Worn the way I wear them (overear, behind my neck with the cord running down the back of my shirt to my iPod ) these have VERY little microphonics from the flat rubbery cord. I would like to see a shirt clip to keep the rather heavy "Y" from pulling the cord down while running but that's minor as I have plenty from other IEM's that I could rig up if these were my own phones. They isolate against outside noise very well also, even to wind noise, which most don't very well, when running outdoors. Of course that much isolation is dangerous when running near traffic but I loved just hearing my music and almost nothing else.
 
Edit 8/12/14: I've been running with these almost exclusively for several weeks now and this morning I went back to my previous go to running/gym IEM's, my TDK EB950's. It was pretty shocking to hear how much more noise I heard while running. Not necessarily a great deal more outside noise but cable microphonics and the sound of the slight movement of the 'phone in my ear canal with each foot strike. These just stay put and don't move around as much with the jarring of running as others do (again worn the specific way I wear them). I'm going to play around with my other IEM's and see which shirt clip I can cannibalize from another 'phone and use on these babies to make them the best, to date, running IEM.  
 
Bottom line these are great 'phones and it's amazing what a single driver can do these days. Since I auditioned them I've noticed that I now bump up the bass boost on all my other headphones to try to reproduce that beautiful lower register that makes music sound like a live performance. I could easily see a 'phone like this becoming my go to IEM for everyday use on anything other than extremely critical listening. Well done Brainwavz. Definitely four and a half (maybe higher?) stars for a 'phone this well built with a compelling sound signature at this price point. 
 
Edit 3/14/15: They sorta "broke". About 2 weeks ago I noticed a fairly prominent drop off in the bass. At first I thought it was a tip issue and started rolling tips but soon realized it was something more. Now I'm pretty careful with my gear but I do use these as my go to 'phone for running and for the gym. After careful investigation there seems to be something loose (a rattle anyway) in the left housing. I'm hoping this is an aberration and not a manufacturing defect or QC problem. I'll contact Brainwavz and see if they want me to send them back to them to do an autopsy. I'm pretty bummed as I feel like these are a spectacular little "everyday" IEM that excel with my 2nd gen Nano unamped.

Disclaimer:  I would like to sincerely thank Salsera and Brainwavz for providing the sample S5 for this review.
 
For most of my audio listening “career”, I haven’t been a big fan of in-ear-monitors (IEMs) or earphone/earbuds, tending to prefer more traditionally designed portable and full sized headphones.  The major issues I had were trying to find the right positioning, fit, and seal to obtain the optimal sound quality.  Earbuds were out because I prefer to block ambient noise and enjoy the music at a level that doesn’t require an upgrade to a hearing aid before I’m 55.  The IEMs I tried before usually came with two or three sets of ear tips that seemed to fit everybody but me and no instructions on how to actually insert the things.  So I never could seem to find the right position for the housings to stay in so the tips could stay sealed so the music could sound good (got all that…?).  Lastly, the overall musical presentation appeared to be geared towards people who prefer to sit between two 20-inch sub-woofers with a 5-inch mid-range speaker pointed at their face (admittedly, the above mentioned factors may have had some bearing on my impressions of the sound).
 
Then a while back I received a set of Brainwavz R3 earphones as a gift when I ordered an iBasso DX50.  While their design was a bit unconventional, I found them to be an enjoyable introduction to the newer styles and design philosophies of modern IEMs.  First, I somehow managed to get them to fit in my ears without them wanting to fall out.  Second, they came with more ear tips (of multiple designs and materials) than I had ever seen...including some that actually fit!  So along with the fit and seal came number three; sound was head and shoulders above what I experience before, approaching the level of quality headphones.  It was enough to open my eyes to the potential sound quality of in-ear phones being made today.
 
Since then, I have tried several different types to include hybrid dynamic/balanced armature, straight dynamic with replaceable filters, and straight dynamic with different types of ear tips that change the quality of the sound.  I have discovered a new world in universal IEMs with sound quality and comfort approaching the likes of some of the high-end full-sized headphones out there.  When I can turn on the music and forget that I am wearing IEMs (or headphones) and only hear the music, then the manufacturers have done their job well! 
 
Which brings us to the S5 Earphones; a fun little phone that may not hit audiophile heights, but brings some unique character of its own to table.  Coming in a black box with a front opening flap displaying the driver housings and flat cable on the outside and providing some general company detail and cross-sectional info on the driver, cable, and Comply Foam Tips.  On the back is the list of accessories and specifications.

 
The Build:
 
The S5s look solidly built with metal driver housings and ear tip posts/acoustic filters.  The filters do not look to be replaceable.  There is a flattened, beveled area near the rear of the housing that has “Brainwavz” embossed on it and a small air-port on the opposite side (blocking this port will affect the sound).  The cable attaches to the housings at the top rear side in such a way that the only practical way to wear these is with the cable over the ear.
 
There are tiny, barely readable Left/Right markings at the cable connection point.  Frankly, I don’t know what the point of even having them is.  Unless they are larger and with better contrast, you have to have a magnifying glass and bright light just to see them.  The good news is Brainwavz designed the housings to be fairly intuitive; so as long as the beveled side of the housings face away from your ears and the ear tips point forward and in (and the cables point up), then they are pointed in the right direction.  BUT…if you are going to put L/R markings on an IEM, make them READABLE!

 
The Cable:
 
I’ve heard about some IEMs having flat cables before but had never had any before.  The R3 cable was rubberized and seemed more like a thick round monstrosity that you would find on a so-called “sport” headphone.  It was very microphonic and not easy to manage at all.  The S5 cable is the polar opposite, with the cable being thin, flat and supple, I find it very easy to route over my ears and thread it through my clothing so it stays put.  While still having a rubberized coating, it is not as thick or nearly as microphonic as the R3.  There is a convenient chin slider at the Y-connector that helps reduce the microphonics even more.  I quite like the cable.
 
The Sound:
 
Disclaimer:  I find that rating sound is very subjective.  There are those that use measurements, there are those that use descriptive comparisons of the frequency ranges in musical passages, there are those that describe the sound qualities of one headphone in comparison to another.  I will offer that none of these are necessarily wrong, but how can I convince you that the sound I hear is what you are going to hear?  I can’t, and I shouldn’t.  I can only offer that the impressions I write down are what I hear based on my listening experience.  Your experiences may be similar, or they may (in all likelihood) be different.  I offer these impressions as an anecdote and as a service.  Feel free to disagree if you wish but that doesn’t make me any more wrong than it does you right.  Okay, enough blathering…
 
I’ll say it upfront; the ear tips made the sound.  I could not get a real good sense of how the S5s were tuned because every time I tried a different ear tip the sound quality changed…and in some cases, dramatically.  So I would like to offer my opinion of the S5’s sound based on each of the sets of ear tips (and only those) included in the package.  My source was an iBasso DX-90 playing some classic rock, folk (acoustic) instrumental, orchestral, and electronica.
 
One other note: Salsera told me ahead of time the S5s needed several hours of burn-in to tame the bass a bit so I burned them in for 30 hours before even trying to listen to them.
 
Silicone Ear Tip, Black, Small Opening:   My least favorite.  Remember my little description of the 20-in subwoofers and 5-in mid-range?  It wasn’t too far from the mark with these tips…okay, maybe 8-in subs, but you get the picture.  They had the soundstage of a shoe box.  I ended up removing and reinserting them in my ears multiple times to ensure I had got them in right but in the end, they were bass heavy with some emphasis in treble and extremely recessed mids…and a super narrow sound stage.
 
Silicone Ear Tip, Grey, Slightly Larger Opening:  Optical illusion?  Those holes look bigger to me.  But the sound..!  I actually listened to these first and the sound stage is much wider than the black tips above.  There is less bass than the black tips and there is a little more of a mids presence.  There is a definite V-shaped frequency response but it is more pleasant.  There is more bass than treble emphasis but the treble is clear and not harsh.  The mids are recessed somewhat but haven’t been overwhelmed by the bass and treble.  I find myself listening with these tips the most.  They bring out the fun in the S5s
 
Comply T-400: Sorry folks, foam tips and I don’t get along and this experience was no different.  The foam interferes with the fit and usually ends up blocking half the sound channel when I try to use them.  If you find that you like them…more power to you!
 
Bi-flange Ear Tip: To me, the most balanced sounding of the bunch!  I admit I do like a slight bass emphasis to my music and the bi-flange tips provide a little of it while bringing the mids forward for the first time and smoothing out the treble.  It was as close to a balanced IEM that I have heard from a dynamic driver and I really liked them a lot.  They are also the first bi-flanged tips that I could get a good seal along with fitting the housing in my ear.  I may start using these as much as the grey ear tips in the future.  I like what they bring to the S5.
 
Tri-flange Ear Tip:  Unfortunately, the tri-flanges took the balance a little too far and removed the slight bass emphasis that I enjoyed so well.  Other than that and the fact the sheer size of the tips made it impossible to fit into my ears properly, these did sound rather nice with some of the acoustical and vocal music I listened to.
 

 
In summary:
 
Using the ear tips that came with the S5 I managed to find a sound I liked.  With the sheer number and types of ear tips available on the market, the possibilities for customizing the sound signature to fit a person's tastes are almost endless.  I’m sure that it would be possible to find a set offering a sound signature that meets your needs with the S5.  I have at least 20 sets of tips that I can’t wait to try just to see how much more fun I can have with the S5’s sound!

PREAMBLE

Brainwavz is a now well established manufacturer of headphones in the value for money category – offering many different options (especially for IEMs) that suit almost anyone’s sonic preferences. I’ve previously had both good and bad experiences with their headphones / IEMs – I previously reviewed and owned their B2 IEMs and HM5 headphones, and both were stellar performers. I also sampled their R1 and R3 IEMs – but unfortunately these didn’t quite tick my boxes as much.

So when D2K alerted the community here that there was a new offering (the S3), and that his trial was really positive, I immediately subscribed to the growing thread. I was then contacted by Audrey and Raz about sampling the S5, and I readily agreed – especially after Luke (H20Fidelity) also suggested that they were well worth looking into.

I received the courier pack earlier in the week – and have already spent most days in that time getting to know the ins and out of these IEMs. I’d estimate that so far I’ve logged around 30-40 hours with the Brainwavz S5. A lot of this involved tip rolling and using different sources and genres to really get a feel for what the S5 offers to different music tastes.

I’ve listed price at USD $99.50 (current Amazon and MP3Nation price at time of writing) – however this is not what I paid for them (they are a review sample). I did contact Audrey offering payment for these IEMs (after I'd written and posted the review) – already I felt they were keepers. Audrey contacted me back, and insisted I keep them as a free review sample, and I am thankful to Brainwavz for this.

DISCLAIMER

I was provided the Brainwavz S5 as a review sample. I am in no way affiliated with Brainwavz or MP4Nation - and this review is my subjective opinion of the Brainwavz S5. I would like to thank Raz and Audrey for making this opportunity available.

PREAMBLE - 'ABOUT ME'. (or a base-line for interpreting my thoughts and bias)

I'm a 47 year old music lover. I don't say audiophile – I just love my music. Over the last couple of years, I have slowly changed from cheaper listening set-ups to my current set-up. I vary my listening from portable (HSA Studio V3, Fiio X5, and iPhone4) to my desk-top's set-up (PC > coax > NFB-12 > LD MKIV > HP). My main full sized headphones at the time of writing are the Sennheiser HD600, Beyer T1 and DT880. Most of my portable listening is done with IEMs - and up till now it has mainly been with the Dunu DN-1000 or the HSA BA100 IEMs. A full list of the gear I have owned (past and present is listed in my Head-fi profile).

I have very eclectic music tastes listening to a variety from classical/opera and jazz, to grunge and general rock. I listen to a lot of blues, jazz, folk music, classic rock, indie and alternative rock. I am particularly fond of female vocals. I tend toward cans that are relatively neutral/balanced. I am neither a bass nor treble head (you could argue that I do like clarity though). I am not treble sensitive (at all), and in the past have really enjoyed headphones like the K701, SR325i, and of course the DT880.

For the purposes of this review - I used the Brainwavz S5 straight from the headphone-out socket of my Fiio X5, iPhone 4 and Studio V3. I did not bother with amping them, as IMO they do not benefit from additional amplification. In the time I have spent with the S5, I have noticed no change to the overall sonic presentation (I do not believe in 'night and day' burn-in). I will allow that the more time I've have spent with these IEM's, the better they continue to sound to me. Personally I think this is a combination of brain burn in and tip-rolling - but I will respect others choice if they interpret this as physical burn-in.

This is a purely subjective review - my gear, my ears, and my experience. Please take it all with a grain of salt - especially if it does not match your own experience.

THE REVIEW

PACKAGING AND ACCESSORIES

The Brainwavz S5 arrived in a very smart retail box (book type) – with an inner container housing the IEMs and accessories.


The packaging is very attractive and I think Brainwavz have put a lot of effort into this. It is functional, but also has a quality (or sophisticated) look to it. The colours simply convey something special. The retail box contains the catch phrase “rich details, smooth bass, over the ear design” on the front cover. A straight forward and simple message – and one it delivers on IMO. On the rear of the box is a list of accessories included plus the earphone specifications. On the inside of the front page is a really nice touch – and shows that Brainwavz are proud of what they are delivering – an expanded internal diagram of what makes up the S5. The inner audio-nut in me loves this sort of thing!


The accessory package is typical Brainwavz – very comprehensive, and quite exceptional for this price range.

First up you get the Brainwavz carry case – which is a hard fabric covered pouch – and easily carries all your tips and the S5. The case is really good because it does offer a lot of protection to the IEMs – but it is definitely more suited to transport in a jacket pocket or bag rather than a trouser pocket – simply due to its height. This is definitely a quality carry case though.


Along with the case you also get a very high quality 3.5-6.3 mm adaptor (which does fit and work perfectly with the S5), a small combined instruction plus warranty information sheet (reverse side), a huge selection of silicone tips, and a genuine set of comply T400 medium tips.


The silicone tips include 6 sets of standard tips, 1 set of double flanges, and one set of triple flanges.

FREQUENCY GRAPHS

I have requested this information – but not sure if it is available. If not, I will re-edit the review and add the information when someone eventually measures the S5. For the record – I’m expecting a relatively flat mid-range, elevated mid bass, upper mid-range and lower treble, and some roll off in the upper treble.

BUILD QUALITY


When I first saw photos – before I’d done the research – I automatically assumed that the body was hard moulded plastic. It definitely looks a lot like the body of Shure’s SE range. Up close – it even looks like black shiny plastic – but when you actually handle them, you realise that it is actually an aluminium alloy - Brainwavz confirms it as aluminium 6061 (info here). The build quality on the S5 shell is extremely good – one of the best I’ve seen at any price. It’s ergonomically designed for the shell to fit relatively flat against the concha – with the nozzle protruding on an angle into the ear canal. The design is such that the body of the S5 sitting against the concha is well rounded, very smooth, and (for me) extremely comfortable. With so many dynamic driver earphones opting for a bullet type shell, it is very refreshing seeing this sort of design option, as I find it aids both isolation and comfort.

The S5 is also relatively light weight and comfortable to wear – weighing in at only 21g, and I think a lot of the 21g is actually in the cable (more on this below). Comparatively, other IEMs I’ve tried recently vary between the very light weight Alfa Genus and BA100 at around 14g, and the DN1000 coming in around 26g.


The strain relief from the IEM housing is relatively rigid rubber moulded onto the housing, and looks of sufficient quality to last for considerable time, and protect the cable very well. L/R markings are printed in very small print on the strain reliefs – but IMO this is not an issue, as the design can only really be worn one way. And that’s another of the great things about this design – it’s easy in no light/low light situations to always get the right ear piece simply by feel.

The cable is a 1.3m flat copper cable in an outer rubbery flat sheath (Brainwavz advises that this material is TPE - more info here) . It seems very solid, but leads to my only real complaint about the S5. The cable is quite microphonic compared to a lot of the IEMs I’ve had the pleasure of trying recently. It’s not the flat design either – it’s simply the rubbery sheath. I tried running in them earlier in the week, and even with them properly cinched, I got a fair amount of microphonics. Wind on the cable yielded similar issues. They weren’t as bad, when walking, and definitely better with the cable properly cinched. Another way to alleviate this might be with a shirt clip, or to tuck the cable well inside clothing. Whilst there are ways of fixing this, it is unfortunate IMO that the design was not altered. I’ve included a photo of the Alfa Genus cable I reviewed recently (similar price bracket) which shows what can be achieved – twisted pair with a low microphonic outer sheath – strong, malleable, quiet. Something for Brainwavz to think about for the future perhaps? The flat cable is comfortable over ear.


The splitter is a little larger than most offerings, but is flat and does have a cinch (neck slider) which works well. Strain reliefs are very good.

The plug is a straight plug which is relatively petite – and I had no issues fitting it to my iPhone with cover intact. Once again, strain relief at the plug is excellent.

FIT / COMFORT / ISOLATION

I have one ear canal slightly different to the other one (my right is very slightly smaller) - so I tend to find that usually single silicon flanges don't fit overly well. I initially tried the grey large silicone tips included, and they actually fit pretty well. I was finding that the seal would get interrupted a little, so I tried my trusty pair of Monster Super Tips (dense foam that almost always give me a complete seal). They did fit exceptionally well – but tended to attenuate the upper-mids and highs just a little, whilst making the bass almost too prominent. So I them switched to the Comply T400s – and ….. perfection (for me). Really good comfort, good isolation, but more importantly the sonic signature returned to a nicely balance mix.

All tips stayed intact with the S5 during insertion and removal, so the design of the nozzle definitely gets thumbs up from me. Isolation with the T400s is good enough for long distance air travel, and the comfort is brilliant. I’d have no issues at all sleeping with the Brainwavz S5 – especially with their flat profile.

So what does the Brainwavz S5 sound like ……… ?

SOUND QUALITY


The following is what I hear from the Brainwavz S5. YMMV – and probably will – as my tastes are likely different to yours (read the preamble I gave earlier for a baseline). Most of the testing at this point (unless otherwise stated) was done with my Fiio X5 as source.

Tracks used were across a variety of genres – and can be viewed in this list http://www.head-fi.org/a/brookos-test-tracks.

Thoughts on General Signature

I’m finding the Brainwavz S5 to have a V shaped frequency response with a boost to the bass presence (and when I say boost, these are in not overly dark or muddy), quite flat and balanced mid-range (nice cohesion between lower mids and upper mids), and a bump in the lower treble. One thing I am noticing is that because there is some boost in the 3-4kHz region, I’m actually listening to the S5 at a slightly louder volume level than I would with other IEMs (I’ve noticed a lot of other IEMs boost this region to bring vocals forward). I tested this last night with the T-Peos Altone200s, and to approximately match the vocal SPL on the A200s required another 7dB on the S5. I tested this with an SPL meter and 3kHz constant tone. – then afterwards compared Christina Perri’s track “Human”.

Overall Detail / Clarity

For this I used both Steely Dan’s “Gaucho” and Dire Strait’s “Sultans of Swing” as there is a lot of micro detail in both tracks, and the recording quality for both is excellent.

The Brainwavz S5 displayed reasonable detail retrieval with a mellow and laid back sound, and just a hint of sizzle from the lower treble. With Gaucho, the cymbals are there, but in the background (behind the vocals). It is a smooth presentation, with no real peakiness – just allowing me to enjoy the track. Switching to Sultans of Swing, and once more the focus is more mid-range than treble. This track shows a little more crispness – but again, no major peaks, and Knopfler’s guitar just really sings. The more I listened to these tracks, I realised that any brightness is probably more on the upper mid-range than the actual treble itself. Cymbals and high-hats are there, but subdued (or polite) rather than brashly represented as some IEMs do.

There is no smearing of detail in either track – so separation is pretty good.

Sound-stage & Imaging

For this I used Amber Rubarth’s binaural recording “Tundra”. I used this because it’s a pretty simple way to get comparative data on sound-stage.

It’s usually difficult to get a reasonable stage size from an inner ear monitor. The stage is often quite small / close – with an average impression of space. The Brainwavs S5 for me is a typical IEM in this regard. The sound – while relatively clear (the drums are probably the most focused), is still very much ‘in your head’ – but still enjoyable. Directional cues are good – so for a value priced IEM its imaging is OK – perhaps not quite as stellar as some of the more detail oriented IEMs I’ve tried recently.

I also used Loreena McKennitt’s “Dante’s Prayer” and the S5 again delivered a very smooth and easy to listen to performance. The sense of space normally exhibited by my full sized headphones (HD600 / DT880) was missing – but the overall presentation was enjoyable and there were some directional cues present. In this track, the applause at the end is so well presented that with some headphones (HD600) I can actually close my eyes and imagine myself in the crowd. With the S5, the clapping did seem a little distant – but there was a sense of space, and the more realistic tone actually does emulate some of what the HD600 can achieve. At this point I retried the ending again, this time giving the S5 a volume boost, and all of a sudden the crowd sprang into life – and the some of the realism I hear with the HD600 was apparent. Quite an achievement at this price point.

Genre Specific Notes

Again for tracks, albums, artists – please refer to this list: http://www.head-fi.org/a/brookos-test-tracks

Rock – For me, the S9’s perform well with this genre, with the most noticeable feature being the smoothness of the overall presentation, and also the very punchy bass. 3 Doors Down “Away From the Sun”, and Alter Bridge’s “Broken Wings” are both nicely presented – but their isn’t the same crunch and excitement with guitar that I’ve had with IEMs with a slightly brighter top-end. Overall though it is very easy to listen to the S5 for extended periods of time, and there is simply no fatigue with any of the tracks I’ve listened to. Even on the much faster “Diary of Jayne”, although the presentation is slightly warmer than I am used to – nothing sounds smeared – the driver is keeping up nicely. Vocals are well presented – but rather than being too far forward, they are really nicely matched with a very present and impactful bass.

Alt Rock – First up was Pink Floyd’s “Money”, and unfortunately the S5 just didn’t quite do this classic track justice. The cymbals this time were almost lost. Bass (especially bass guitar) was exceptional, vocals were nicely presented, even the sax was well represented, but the top end detail was unfortunately missing. Switching to Porcupine Tree’s “Trains”, and here is a track that suits the S5 really well. The bass is just gorgeous – and this time even the upper end is present. Best of all Wilson’s voice just really suits the S5’s relaxed vocal presentation.

Jazz / Blues / Bluegrass – I started with Portico Quartet’s “Ruins” and enjoyed the presentation – but missed some of the crispness that I normally get with the sax in this excellent track. Moving to Miles Davis “So What”, and whilst it’s a pleasant and non-fatiguing listen, some of the finer details (particularly in the cymbals and high-hats) are simply not where they should be. There just isn’t the contrast. Miles trumpet is intoxicating though – and the S5 does the master justice with a presentation as smooth as his playing style. Switching to Blues – I fired up Joe Bonamassa’s India-Mountain Time, a track that I like immensely. The guitar work is very different to what I am used to – slightly darker with less sparkle and crunch. But it’s still Joe doing what he does best – and once he starts singing, I actually like the S5’s presentation of his vocals very much. Switching to “Dust Bowl Children” (Alison Kraus and Union Station), and the S5 also does this pretty well. A little less excitement in the banjo than I’m used to – but the cohesion between vocals and stringed instruments makes it a very easy listening experience.

Rap / EDM / Pop – Eminem’s “Lose Yourself” shines with the S5 – everything works together very cohesively (vocals, bass, guitar), and it’s surprising how much bass these drivers can deliver with the right song. What surprises me though is how clear the song is despite the copious bass it’s putting out. I think even bassheads would enjoy the S5! Switching to Norah Jones “Light as a Feather” (a fusion of pop with jazz undertones), and it is pure vocal heaven. I could listen to this sort of presentation for hours. In fact most Pop in my library just sounds right with the S5 – vocals shine, bass is impactful, again the word cohesion comes to mind. Switching to EDM – I tried Lindsay Stirling’s “Electric Daisy Violin”, and I was blown away by how good these are for this type of music. There is enough upper mid-range to make Lindsay’s violin clear, smooth, and utterly enjoyable. And then there is the bass, thumping, but clearly defined – just the perfect compliment. I also tried some Little Dragon and some Flashbulb – and it is clear to me, most electronic music shines with the S5 IMHO.

Classical / Opera – This was a surprise wasn’t really expecting. I thought the S5 might be a little too smooth for these genres, but I really enjoyed them – especially with Netrebko and Garanca. Even Kempff’s Moonlight Sonata was very captivating, and I think this might be one of the S5’s hidden strengths. Because it has such a balanced mid-range it can convey a sense of realism with individual instruments (eg piano) which is sometimes lost when the mid-range is too forward.

AMPLIFICATION REQUIREMENTS

The S5 is very easily powered straight out of virtually any portable device, and I didn’t experience any issues with the 3 DAPs I tested (iPhone 4, Studio V3, or Fiio X5). Of the three – my personal preference would go to the Studio V3’s slightly brighter presentation.

RESPONSE TO EQ?

I was keen to see what the S5 could do by applying a little EQ. So feeling somewhat lazy, I simply switched to my iPhone, fired up the Accudio Pro app, and loaded an HD600 base signature with a K701 mask over the top. I went back to Portico Quartet’s “Ruins” again, and this time the detail I was missing earlier was more present. So the S5 responded really well to EQ for me. This is something I need to look into further as I use these more.

COMPARISON OTHER IEMs – DN-1000, BA100, T-Peos Altone200

Track – a personal favourite of mine – Pearl Jam’s “Elderly Woman Behind The Counter In A Small Town”

Vs HiSound Audio's BA-100
Hands down my preference is the S5. It’s amazing after having these in my ears for a few days how thin the BA100 is in comparison. I know that’s just my brain not used to the very contrasting sound signatures – but I didn’t think the difference would be this large. The S5 has beautiful tone and excellent timbre with this track. The BA100 is clearer, but it simply seems to lack body.

Vs Dunu DN-1000
This time it’s a lot closer – but where the BA100 was thin, the DN-1000 is fuller, and delivers both tonality, but also a clearer presentation more suited to my individual tastes. The S5 definitely competes well though, and is definitely not embarrassed by its much more expensive competition. Where the DN-1000 has a little more sparkle and contrast, the S5 still delivers better bass impact, and is smoother. I actually may also prefer Vedder’s voice with the S5 …….

Vs T-Peos Altone200
This is a tough one because the presentations are quite different – but they are quite close in price at the moment. The Altone200 will sit eventually around the $150 mark, so I suppose it is a little unfair on the S5. The S5 continues to be very full bodied, with excellent timbre and tone – and is very smooth. The Altone200 is not quite as full bodied, but has excellent bass presence, and superior upper mids and treble. For this track I may have a slight preference toward the T-Peos. But that is no doubt my personal preference for a little more sparkle and energy.


BRAINWAVZ S5 - SUMMARY

Those who’ve seen my reviews before will know that I tend to write reasonably long rambling ones. So once again, if you’re still with me to the end, my thanks.

The Brainwavz S5 is an extremely well built IEM with a mildly V shaped sound signature, very good tone and timbre, and excellent comfort and fit. Once again it is an IEM that belies its $100 price range – delivering superior sonics at an incredible value. It has an emphasis on bass impact, but does not come at the cost of clarity or smearing into the mid-range. The mid-range itself is quite linear, the lower treble has some "sizzle", but the upper treble is what I would call polite (definitely not a focus). The S5 has a very smooth overall signature which suits many genres. Treble-heads, or people preferring brightness and etched detail should definitely look elsewhere – unless they are willing to rely on some EQ (which the S5 responds to quite nicely).

The one fault I do find with the S5 is that the cable is perhaps a little too bulky, and is definitely microphonic – but this can be managed to minimise the effects.

The litmus question again for me would be “would I buy these for myself”, and “would I recommend them to my family”. The answer to this question is YES – and I did indicate to Raz and Audrey that I wanted to purchase them. They have insisted I keep them as a free review sample, which I do appreciate. I will reiterate though that I did offer to buy them - which shows how I do regard the S5.

These are easily the best Brainwavz offering I’ve tried since the B2 (a few years ago).

Edit 8 Oct 2016 - revised these down by 1/2 star - value today is not as good as it was when first released. Still sound pretty good for a V shaped IEM, but might struggle today at USD100 mark

RECOMMENDATIONS TO BRAINWAVZ

Consider changing the cable to something lighter and less microphonic

Brainwavz have been around since 2008 and have been working on providing improved and more original products as time has gone on. If you are familiar with the last round of Brainwavz offerings it was easy to see how they were improving and what they were attempting to try design-wise. We did see a very wide range of products from the brand in the Delta, S1, and R3. Fairly unique from each other in design, sound, and price. They have now introduced the S5 model priced at ~$99 with an excellent blend of sound traits, design, and quality. Many thanks to Audrey for sending me a pair of the S5.

Accessories:  Listed and pictured above include Comply brand foams, single, bi- and tri-flanged silicone tips. So all types are represented. The range of tips do provide multiple fit and comfort options but they also tweak the sound certain ways. In my experience, the Comply provided the most balanced and clean sound. The tri-flange a more neutral sound with the least bass amount. The bi-flange which is slightly different than the generic type is nice for a warmer bit of bass boost w/o sound quality degradation. The black silicone sound like a slightly smaller version of the bi-flange as the smaller opening knocks off some height from the stage. The gray tips are warmer and have more bass and thicken and compress the sound a bit; might be nice for a neutral player pairing but may also darken and thicken the sound hurting the dynamics and detail/brightness. The 3.5 to 6.3mm adapter is aesthetically different than previous one with the red stripe and more mirror-like finish.
 
S5 Design:  The design is much like the S1 model with some changes. The larger forty-five degree plug is gone in favor of a smaller straight plug. The housings are longer tapered design with a black semi-gloss finish. The strains coming out of the housing have been shortened from the S1 length. The Y remains the same outside of the color change for the Y, plug, and strains from purple/berry-like color to black.
 

Picture showing the exposed view of the basic internal design. The presentation of the sound would seem to be influenced from the design. The upfront, more in your face nature from the close to the bore driver is quite different from the R3's more distant and airy sound with its drivers back at the ends of a capsule. The decent cavity size behind the driver should indeed be helping give the S5 it's nice large stage and good depth even with their close, up front nature.
 

Build Quality:  The S5 are solidly built with strong metal housings that are coated in a seemingly thick black semi-gloss finish. A bit of sheen yet not shiny enough for fingerprints to be an issue. The S1's hefty cable and Y are still present and still sturdy. The strains are strong and a bit stiff all around. As before a bit of physical manipulation, moving them back and forth some will break in the plug and Y strain reliefs a bit so they flex more easily. The cord draw tolerance is nice and tight, not overly so, and it will stay at the position you want or need.
 
Fit and Comfort:  The S5 are designed as an over the ear phone but I have no problem wearing them both ways and more often wear them straight down. The shorter reliefs out of the housing makes this even easier than with the S1. The angled sound tubes provide a more flush fit over the ear. Enough styles of tips to achieve a good fit and seal for most everyone. Isolation depends on the tips used and ranges from average to above average. The S5 are quite comfortable for me regardless of wearing style. The weight of the thicker cable, while not uncomfortable, is always there. The S5 are not going to "disappear" like a smaller, lighter earphone may.
 
Sound Quality:  The overall sound quality is excellent. The Comply and bi-flange are my favorite tips for sound. As with many dynamic earphones, trying to get the absolute best seal will thicken them up a bit and make the bass a bit more dominant and the treble less apparent. Obviously fit them to your preference. An in-between fit renders a full sound with warmth, a slight bass emphasis, even mids(not recessed, not forward), and a nice treble sparkle.
 
Bass is clearly dynamic, well extended, capable but not really quick. Mid-bass is under control nicely and there is good detail and texture down low. The bass is fairly tight. Not the tightest you'll get like from an armature or much more expensive dynamic but a little more weighty and rounded of note which is a great spot in between the consumer sound and the audiophile sound. The bass stays out of the way of mids and gives some rumble and adds towards giving the S5 a larger sound.
 
Mids and vocals are quite clean and easy to hear. Make a fine showing even with the solid full bass presence and treble sparkle the S5 can have. The up front sound puts the vocals, and even back-up vocals, close and in good focus. Detail is good, words articulated more highly, and emotion shows well. "Shhh", "s",  and "f" sounds are emphasized without sibilance helping show the singers inflections and energy, and emotion. Vocals are quite engaging and draw focus here but without being really sweet or syrupy. Just good quality mids that are not too light or dark, thick or thin, sweet or dry but safely in the middle in most aspects.
 
Treble is nicely extended and sparkly enough without going too far. A best possibly seal situation will smooth them though leading to a less energetic and lively sound from the high end. The treble is nicely detailed and helps the mids be quite clean. They help give the S5 good energy and a more lively sound which is very engaging and stands out over other phones. Good decay on the high notes helps give a sense of air and better separation. Fatigue is not an issue.
 
The overall presentation is a sound that is quite forward, quite engaging, and exciting. A bit wider than tall with good extension in both directions, good depth, and nice separation. It does tend to grab one's attention as a few reviewers have attested to already. The forwardness of the sound combined with good clarity and sparkle gives an immediacy that is engaging and shows the S5's detail easily. Yet they don't fatigue or offend. They strike a likable balance between smoothness and sparkle. The S5 are also enjoyable due to their above average stage size and fullness of sound. The sound fleshed out and almost like they are amped even if not. Combined these previous traits with nice technical ability in terms of extension, resolving power, timbre that makes you not miss anything even if the S5 aren't detail or transparency kings. Again a really likable balance that many more people will like; that consumer sound fans and Hi-Fi fans can both enjoy and be drawn to. 
 
Conclusion:  Brainwavz have hit on a well done recipe of sound traits. Their best balance yet of smooth, full, enjoyable, and technically capable. One of the best for the price right now I'd imagine. In addition to the sound the build, packaging, accessories, and price are all quite likable as well. Brainwavz has a real winner here that is worth hearing!

Disclaimer: I am reviewing a pair of the S5 I received from Brainwavz for reviewing purposes.
 
OK, I have reviewed several Brainwavz over the years and they have always managed to nail a great balance between cost and sound quality with only the occasional miss. The S5 manages to continue that trend admirably. I will be blunt, the S5 is their best dynamic based IEM they have created to date. Taking other S series models I have reviewed in the past the S5 takes the best of those IEM's and refines and perfects those qualities. I have not taken a ton of pictures for this review as other more qualified than I, with better equipment have already done so, I will simply stick to a written review.
 
Packaging and accessories:
 
The packaging reflects the dedication and quality of this IEM to a tee. It looks fantastic and gives off just enough luxury without coming across as pretentious or over the top. I love how the IEM cable and accessories are all nicely tucked into the Brainwavz standard clam shell case. As usual the IEM comes with pretty much all of the standard minus one thing, there is no shirt clip which would have been a useful item due to the weight and design of the cable.
 
Build and design:
 
This IEM is similar to the S1 in regards to the cable and strain reliefs but is slightly less heavy and bulky. Having said that, I hope Brainwavz continues to reduce this area while retaining the durability they have achieved in their products. This IEM utilizes an I jack and does not offer any form of mic or controls so is designed strictly for playing music and as such is as at home with a home desktop rig or portable amplifier as it is with a portable MP3 player or phone. For my review I am using my LG G2 phone for my source. The IEM itself is a curious looking torpedo design with a bend at the end to accommodate the ear. This design looks great in ear in my opinion and is also very comfortable. The isolation is what I would consider average for an IEM, not super isolating but good enough for most situations.
 
Bass:
 
I find the bass of the S5 to be pretty hard hitting and emphasized. The emphasis works with most genres but I did find it to be a bit to strong for some of the jazz I listen to and a bit over powering for some of the older classic rock I listen to. For music designed to have more bass it works very well though and is great in music that does not have a strong bass presence as it does not CREATE bass just emphasizes what is there. It also does not seem to intrude into the midrange even though the mid-bass has a slight hump which is a good thing.
 
Midrange:
 
The midrange is clean and nicely present. It lacks a small amount of detail but not enough that you feel there is something missed unless your doing straight up A/B comparisons. The midrange is slightly recessed in comparison to the bass and the treble though. This slight dip has a tendency to make me want to crank up the volume a bit which can then make the bass in particular come across as to strong.
 
Treble:
 
The treble of the S5 is clean and sparkly with little to no graininess and is nicely detailed without becoming hot or to energetic. In all of my testing I never once felt fatigue from the IEM after a listening session even though I did have a tendency to turn them up louder than usual.
 
Sound stage:
 
The sound stage and imaging of the S5 is slightly narrower than some of the more expensive IEM's I have heard as well as a couple of the cheaper IEM's. But in defence of the S5 the cheaper IEM's all achieved a larger sounding sound stage through sonic trickery that often affected their sonic quality in other ways. While more expensive IEM's were, well considerably more expensive... Overall I find the imaging and sound stage of the S5 to be very good for the price of the IEM and certainly adequate for most of the music I listen to.
 
Genres of music tested:
 
I listen to Christian Rock, classic rock, Jazz, country, Celtic, acoustic, New Age, classical and more. The only genres I don't listen to are things like death/speed metal, dub step, trance, and hip-hop. In regards to the genres I listen to the S5 worked very well for Christian Rock, acoustic, New Age, and most classical. It also worked OK for country, classic rock and Jazz but the bass would occasionally be to strong with those genres. The good news is the IEM responds well to EQ'ing so it is very easy to tune down the bass if needed.
 
Conclusion:
 
I have to say I really think Brainwavz has nailed this IEM very well. It offers a wonderful sound for almost any music and is an excellent starting point for anyone wanting to take their first big step into more expensive gear. I hope it doesn't get lost in the Head-fi shuffle of extremes in regards to signatures, unknown flavours of the month brands, and "new" or "different" technologies that quite often overwhelm just good old fashioned standards and solid design in the forums.

I´m a 38 year old father of 2 children who has a wife that is totally against anything that isn´t music out of the carstereo. I have been forced to take my HIFI from Cerwin Vega, B&W and KEF speakers to portable audio and headphones to save my marriage.
I was given the chance to review the Brainwavz S5 and this review is based on my subjective listening experience and is not influenced by anything but the gear I have at my disposal and the music I´m listing too.
In this review, and all review I do, I use the same tracklist and listen for specific things in the tracks. I listen to different genres and try to keep a good mix of different types of music and sounds. All tracks are FLAC. The tracklist is as following;
 
·         Sun Kil Moon – Third and Seneca
·         In Flames – Ropes
·         Fleet Foxes – White winter hymnial
·         The Middle East – Blood
·         Niki and the Dove – Love to the test
·         Queen – Innuendo
·         A tribe called quest – Get a hold
·         Yanni – Adagio in C minor
·         Elvis Costello – Alison
·         Dave Matthews Band – Grey street
·         Etherwood – Cast away
·         Rage against the Machine - Vietnow
 

 
 

Brainwavz needs no introduction. They have been in the IEM market long enough that they have made a name for themselves, especially in the bang-for-bucks section. The S5 has been in the market for a while now, and the price has dropped from the initial US$130 to the current US$100. However, the price tag is still right in the ‘warzone’ as far as IEM goes, where many competitors coming from China are all trying to outdo each other for being the next budget giant killer. So how does S5 fair?

Packaging, Accessories and Build Quality
S5 is beautifully packaged. Then again, I won’t expect anything less from Brainwavz with their outstanding track record. Of course they didn’t skip on accessories as well. You will get a pair of Comply foam tip, a pair of tri-flanges eartips, a pair of bi-flanges eartips, 2 set (S, M, L of a total of 6 pairs) of single flange eartips with slightly different design and material. There is also a good looking hard case as well as a 3.5mm-to-6.4mm stereo adapter. All and all, they really give the S5 a premier feel.
 

 
Build quality is top notch as well. The IEM itself is pretty much over-built like a tank, with flat cable, adequate strain relief and overall attention to detail. Though flat cable probably isn’t going to be everyone’s favourite, the over-the-ear design does make the cable much more tolerable in actual use than in a straight-down configuration. I just hope that they had used a narrower flat cable, then it might better appeal to those who really just don’t like flat cable. One area I do want to give credit to the flat cable is that it is hard to get it tangled.  There is also no real driver flex to speak of, which is a good improvement over previous Brainwavz models that tend to suffer from some degree of mild driver flex issue from time to time.
 

 
Sound Quality
Sound signature wise, S5 is probably best described as U-shaped with good presence on both ends of the frequency response. Bass has very good depth, rumble, texture and quantity - enough to satisfy bass head but still in a well-controlled way that it won’t offend those who don’t particularly enjoy bass. Mid-range however is a little bland – not bad per se, but doesn’t have much to praise of either. Treble has good extension, clarity and crispiness, but the lower treble / upper vocal range has some noticeable peaks that can become rather edgy when the volume is pushed too loud. Soundstage is quite good, might not be the best but definitely well above average.
 

*Compensated. Measurement accuracy is not guaranteed

*Measurement accuracy is not guaranteed
 
All and all, the graininess on upper vocal is probably the only real weakness as it makes S5 more appealing to those who like brightness in their music. Tuned that down a bit, maybe by the use of foam tips or extra filter / acoustic dampening, and S5 will shine.
 

 
Sum-up
There are some really great sounding IEM coming out of China these days on incredible low price, enough to rewrite everything we know about the ratio of price vs. performance. While S5 won’t win the price war these days, it is still a very solid offering on its own right. As I imagine, Grado fans who usually don’t mind a bit of brightness will probably also enjoy this IEM with their Rock music.
 
A thanks to Brainwavz for the sample.

The new S5 from Brainwavz will certainly please most casual listeners. It's sleek design, tangle-proof flat capable, and pop-ready sound signature certainly justify it's price - not to mention probably the best IEM case I've ever seen short of an Otterbox. 
 
Before I get into it, I owe a thank you to the good people at Brainwavz for reaching out to me for a review. They shipped the IEM to me quickly and have been very courteous and communicative throughout the review process. Disclaimer: I'm not affiliated with them in any way. 
 
(If you want to read about the packaging and included accessories, check out one of the numerous other reviews, as this one will jump straight to the point: the sound)
 
Out of the box, the S5 sounded a little lackluster. The midbass was a bit muddy and bled into the mids. The treble was very hot and almost unbearable on treble-heavy tracks. But in an effort to remain fair, I gave these guys multiple chances and I'm quite glad I did. 
 
After ~50 hours, the midbass has tightened and the sub-bass has made its presence known. The mids are now much less cluttered and quite listenable. The treble has cooled, although changing to foam tips calmed them more than the burn-in. 
 
So now that they've gotten some more devoted head-time, here's the breakdown.
 
Test Songs (all MP3 320):
 
Someone Like You - Adele - Live from Royal Albert Hall
Late in the Evening - Paul Simon - The Essential Paul Simon
Wake Up Everybody - John Legend and The Roots - Wake Up Everybody!
What About Me - Snarky Puppy - We Like It Here
Firewall - Steve Vai - Real Illusions: Reflections
Hide and Seek - Imogen Heap - Speak for Yourself
Prelude from Cello Suite #4 - Yo Yo Ma

Mobile: Sansa Clip+ & iPod Classic 160GB > iBasso D-Zero
 
Bass:
Well, in a word: tasty. The sub-bass is present! In my experience, this is someone quite uncommon in sub $100 IEMs. It's nice to hear the low notes in "Late in the Evening" and "What About Me." The midbass is a touch boosted, but certainly not overly so. It adds a little oomph to pop/rock/hip hop, yet doesn't make the classical or jazz stuff sound unnatural. Very well done.
 
Mids:
Rich and in place. Neither forward nor recessed. The mids are very lifelike in they're portrayal of texture and detail. The horns in the Simon and Snarky Puppy are very clear and textured. Vocals sound excellent in "Hide and Seek." Very organic and rich. That's all I have to say about that.
 
Treble:
The treble is make-or-break according to the tips (and quality of the source material). I found it a little hot and sibilant in most instances ("What About Me," "Firewall"), although bear in mind, the iPod/D-Zero has a neutral to bright sig. There were a few times with the stock silicone tips that the treble was hot enough to make me skip tracks. However, with a little EQ-ing and a change to the included T400 foam tips, it was pulled back a little to reveal a detailed treble that works well for the same genres that the midbass helps. 
 
Soundstage/Separation:
The soundstage is nothing to write home about. It's on par with similarly priced IEMs like the Shure SE215 and Hifiman RE400. Not large or deep, but not congested either. Instruments are easy to place and pick out individually. A nice bonus for an IEM with a very consumer-friendly signature.
 
Final Thoughts:
Overall, I would recommend this IEM to anyone looking for a very durable and comfortable solution for popular music genres. The midbass boost and spicy treble work quite well for electronic, rock, and hip hop-styled genres. However, as mentioned above, the treble can be a little too hot at times, so sensitive ears beware. All in all, this is a solid offering from Brainwavz that will compete quite well with the established in-ears in this price range like the RE400, SE215, and FXT90.
 
Edit:
I've been giving these guys some more head time with some new source material and I have some impressions to add! They've been hanging out with the Fiio X5 (MP3 320) all week and the treble peakiness is almost (but not quite) gone. The thick tasty bass and rich mids are still there too, and the soundstage is a little improved, although the X5's exceptionally black background may be the largest reason for this. In any case, it's good to know that the S5 seems to scale will better gear. I'm not finding the qualms I had with them before in this setup and it's like I'm getting to know them all over again!

REVIEW: Brainwavz S5

Packing & Accessories:

The S5 arrives in the same box as the previous S1 and as usual, Brainwavz are very generous with their accessories pack:
3 pairs (S/M/L) of single flange grey tips
3 pairs (S/M/L) of single flange black tips
1 pair of bi-flange tips
1 pair of tri-flange tips
1 pair of Comply Foam T-400 (M size) tips
Carrying case
1/4" Adaptor




Build & Design:

The new S5 is almost identical to the first of the Brainwavz S series, the S1, and as such boosts a very good build quality in every part. Apart from the straight plug and black color scheme, the housings are the main difference, still of aluminum material which is pretty good, but with a more ergonomic design and slightly lower profile. The plug is well relieved, and just the Y-split is a bit large. Probably the main issue would be the flat cable; while sturdy, it's also thick and quite springy and too rubbery. No memory effect but not too well behaved, with average microphonics level. Not a deal breaker for sure, but should be taken in count.




Fit, Comfort, Isolation:

Personally, I find the S5 to be a very good upgrade over the S1. The housings are a bit smaller and easier to fit in both configurations and can be used for long listening without causing discomfort. The cable is a bit annoying and a shirt clip should have been included. Isolation is pretty good, definitely above average for a dynamic based earphone and the inclusion of Comply Foam tips should help even further for some.




Sound:

The S5 is not just better in fit and comfort over the previous S1, but most importantly in sound performance, as should be expected for a new earphone that enters the $100 price tag.
The signature is the very popular V-shaped sound, which is usually very easy to either like or hate, depending the tuning. For a lively sound the S5 performs pretty good, mixing a fun factor with decent level of details.

Bass is pretty strong but not extreme. While it takes a step back in quantity compared to the S1's heavy bass, it's been really improved in quality, showing much better controlled behavior and accuracy. Technically, sub-bass reaches as far as the dominant S1 did, but not as obvious and free. Good layering overall with an added authoritative mid-bass lift for 'fun' but not sure it'll be for everyone liking. It's not as annoying as the last M5 and less noticed than the well regarded budget IEM, Xiaomi Piston 2, but should still be taken into consideration.

Midrange is where v-shaped earphones usually differ from each other. The S5 mids are quite good on their own. They are placed a bit distant as expected but far from being called lost (a certain flaw on the S1). They do carry some fullness (due the bass) but feel somehow cold and dry. The main issue is the tonality, as the S5 leans more to the artificial side of things and lacks in texture, especially in the vocal dept. Much better than older models for sure, such as M5, S1 or Audiofly AF56, but won't put the RE-400, KC06/6A, ZA Tenore or even the ATH-CKN70 in danger anytime soon. The Moe Audio SS-01 (dual dynamic), for example, shows better texture and sounds much sweeter but also feels more closed and intimate against the more spacious S5.

Fortunately, the Treble was taken into another league than the previous Brainwavz models. The S1 I tried had a serious and almost unbearable peak and sometimes extreme harshness. While the S5 is not completely clean sounding, it is much more refined and enjoyable. Extension is pretty good, mirroring the lows to complete the whole balance. Stage is quite wide as expected for a v-shaped signature, and overall detail plays a decent role. Imaging and instrument separation are decent but will feel very average compared to the most resolving and natural sounding RE-400 and Ostry's options.

The included different tips array can help tuning the sound in a certain way, from warmer/darker (single grey tips) to flatter and more spacious (bi-flange tips) to a more V-shaped and sharper sound (single black tips).

As far as SQ goes, the new S5 is a much higher step over the first S1. Is it 5 times better? Well, not exactly (doesn't costs 5X the S1's price, either), but it's a real improvement over the S1 which despite some strong characteristics, had some flaws on the treble dept. and probably in the midrange too.
Targeting the $100 market there's some stiff competition, including BA and Hybrid based sets. But if we take in count the generous accessories pack and robust build quality together with a caring customer service as well, and we get another solid buy from Brainwavz.

Disclosure: This review is based off a review unit of the retail version of the S5, provided by Brainwavz. This is my first in-depth encounter with a Brainwavz product, having only demoed previous Brainwavz products very briefly in Hong Kong three years ago.

Battleground: The Sub-$100 Price Category & The Dichotomy of Sound Philosophy

 
The sub-$100 price category is an all-important battleground for earphone manufacturers. It used to be the sub-$60 or sub-$80 category that was a hot topic of debate, but pricing expectations for earphones have gone up in recent years and $100 is a viable option for everyday consumers that desire to stretch their (usually zero) budgets in the name of better sound quality.
 
Year after year, premium earphone makers throw their entrants into the ring --- for less than a single Benjamin, you can buy into a HiFiMAN RE-400, an earphone almost universally lauded for having performance that stretches well beyond its price point, or urBeats as a status symbol of the consumerist premium earphone.
 
Sound quality ranges widely in this area, from painfully accurate in the lower-end Etymotics to bass cannons like *redacted*, and thus the sub-$100 category also represents a fork in the road for manufacturers --- a point where they either decide to pursue acoustic performance or go after nice materials and design.
 
So where does Brainwavz stand in this conversation? Brainwavz started out essentially rebranding OEM products as IEMs were just beginning to take off in an industry littered with $5 throwaway earbuds. Typically, OEM acoustic designs are quite competent and follow conventional rules of sound design; it's the manufacturers that tend to come in and say, "Can you add more bass? More treble?", and end up stretching a reasonable, low-cost design into distorting monstrosities.
 
Brainwavz, on the other hand, has mostly kept on its own path, carving out a niche market that allows discerning listeners a price-conscious alternative. It is this niche that has allowed Brainwavz to flourish with a loyal customer base that has continually increased over the years. It does, however, face the same dichotomous question that other, larger manufacturers have long considered (and decided on): do we want to grab the mainstream, or do we keep the enthusiasts happy? The businessman's answer is "both", but real-world execution doesn't come down to a one-word summary.
 

Brainwavz includes a great, semi-hard carrying case with the S5, along with lots of accessories.
 

Build Quality, Ergonomics & Accessories

 
This area is Brainwavz' strongest suit. With ruggedized strain reliefs to the rock solid machined metal earphone housings, the S5 sports a tank-like build that puts the Westone ADV series of adventure-driven products to shame. Some might even argue that recent Brainwavz products are even "overbuilt", opting for big, bulky Y-splits in the name of indestructibility.
 
One thing's for sure, however: even if you stash the S5 in your pockets in the most ham-fisted manner on the daily, it'll stand up to basically any kind of abuse imaginable. The S5 was built for the 14 year-old that tosses his earphones (and smartphone) four feet into the air toward his bed when he gets home from school. It was built for scrunching up into a tangled ball and stuffing into a pants pocket. The S5 needs not be babied.
 
The overall shape and design of the S5 reminds me of an old mainstream bestseller IEM --- the Klipsch Image S4. The wear style is very similar, and so a secure fit will actually make the earphones look like they're slightly sticking out of your ears (not too much).
 
The fit kit is generous; Brainwavz includes two sets of S/M/L single flange silicone tips (one set is black, the other translucent grey, the two are of differing density), a set of wide-mouthed double flange tips, a set of triple-flange tips, and a set of Comply foams. Isolation was surprisingly good with the included bi-flange tips. For me, the bi-flange tips also yielded the smoothest treble as well, so I've settled on them as the de facto tips for the S5. Delightfully, isolation with the bi-flange tips was much better than expected. I rarely have high expectations for isolation in dynamic driver earphones, but I was able to obtain a great seal with the S5 and remove myself from ambient noise.
 
To top things off, included inside the excellent semi-hard carrying case is a 3.5-to-6.3 mm adapter for plugging the S5 into 1/4" jacks. Service-wise, Brainwavz allows for a two-year warranty. Their magnanimous protection plan is considerable for a circa $100 product.
 
It's strange that the S5 doesn't have an in-line remote version, though. Perhaps it'll come in due time.
 

Extremely robust strain reliefs and Y-split. Almost too much so.
 

Sound: What The S5 Does Well

 
The S5 feels designed specifically for music that populates today's Top 40 charts.
 
RiRi's (or is it Sia's? ) Diamonds is "perfect" with the Brainwavz S5:
 

 
The bass slam is just the right amount to keep club-goers interested, while Rihanna's voice is spacious without being overwhelmingly forward. In reality, the S5 imparts a V-shaped signature that will set vocals back just a bit for every track. The balance is such that you'll feel the space in every track, relative positioning isn't necessarily its forte.
 
If you like big, hard-hitting bass, the S5 will deliver on that front --- the S5 possesses quite the adept low end. This isn't the kind of soft, spongy overly decaying bass found in most bassy IEMs --- no, this is solid, in-your-face, quick-on-its-feet bass. You'll hear (and sometimes feel) the bass all the down to 20 Hz. It doesn't drag its feet.
 
Because of the bass' sprightliness, the S5's midrange comes across relatively well despite its reluctance to come to the front row. Detail levels are admirable for an earphone of this price level; considering the amount of bass present in the S5, anyone can hear a copious amount of detail in both the midrange and the treble.
 

Sound: What The S5 Needs to Improve On

 
The S5 goes quite a bit beyond "balance" for the bass, though. People used to listening to earphones tuned in the vicinity of "neutral" will find the balance patently tips in favor of the bass. You'll always hear the bass line, and sometimes that effect is distracting. Should he ever put on a pair of Brainwavz S5, Swaggy P might bob his head to 'Fancy', but he might also wonder where Charli XCX ran off to, because the S5 makes it seem like she stayed in Tokyo.
 
In addition, despite clear improvement within the first twenty or so hours of runtime, treble can come off a bit splashy. Its aggression definitely can be reined in by a little bit, as it makes the Shure SE215 sound like an innocuous kitten. Treble extension, while not exactly poor (probably above average for its price range), can be better. The clearest evidence against the S5 would be in the synthesized crash cymbals of the first half of K.Dot's 'M.A.A.d City' --- they do not fade away as naturally as they do with the Zero Audio Carbo Tenore.
 

Why I feel a little "meh" about the S5

 
For a minute, allow me to veer away from political correctness and pander strictly to the male crowd. To me, the S5 feels like Kate Upton --- bountiful blonde locks, buxom curves and all. The S5 is absolutely great if you dig that style. I, however, prefer the sensibilities of Audrey Hepburn. While I appreciate the multiple SI covers, the zero-G photoshoot, and transformative All-American image, I can't help but continue to seek out my huckleberry friend. You can deck Miss Upton out in Tiffany & Co. and zip her into a Givenchy dress, but she'll never channel Holly Golightly authentically, and that's where I have a problem with the S5. I'm continually searching for an earphone of timeless persistence, but the S5 seems like it's built for "right now". If so, it's curious that Brainwavz has chosen to go this route, as it has traditionally attempted to appeal first to enthusiasts before the masses. This time, they seem to have gone full bore for the casual listener. It's the difficult, dichotomous choice that manufacturers have to take when navigating this price category.
 
I do give Brainwavz an "A" for effort, especially in the accessories and bulletproof build quality, but the sound of the S5 doesn't quite speak to me on the whole. Brainwavz has been successful in appealing to the consumer that wants superior sound quality for the money. In my opinion, however, it hasn't been successful in coming out with an "iconic" product --- something that'll last in the eyes of the consumer. It doesn't have an ER4, a Klipsch S4, or even a CX-300. That's probably what's missing from Brainwavz at the moment. In my estimation, they need a product that emphatically spells, "This is a Brainwavz product, and we stand for great sound," and will continue to do so for years to come.
 
As I've mentioned, the kinda-sorta premium earphone market is a brutal, cutthroat segment of the industry. It's almost required for manufacturers to roll out yearly with new things to keep the peanut gallery happy. However, in the eye of the enthusiast, it is the lasting product that stands the test of time that is most worthy of loyalty.
 

Suggestion: A "Pro" Version of the S5?

 
Originally, the Brainwavz S5 was supposed to be called the "S5 Pro". Upon release, however, the "Pro" was dropped from the name. I found that choice interesting, as though Brainwavz decided the S5 was for the masses rather than the prosumer. Perhaps the omission of the "Pro" connotes that a more enthusiast-oriented version will come to light.
 
With a single 10 mm dynamic driver, the S5 is a conventional design. Last year, Brainwavz released the R3, a dual dynamic driver design with the drivers pointed opposite to each other, injecting into a single resonant sound chamber. However, the single dynamic driver paradigm will forever be viable; should Brainwavz decide to release an "S5 Pro" version in the future, it should consider using a dynamic driver with a superior diaphragm technology, such as titanium coating or liquid crystal polymer coating. Breakthroughs in material science are allowing moving coil diaphragms to transcend limits of breakup resonance nodes, ridding the S5 of splashiness and enhancing its treble extension. Of course, Brainwavz should also pay attention to the housing chamber as well, as housing resonance control is as equally important to acoustic performance as is diaphragm technology, if not more. Should the end product be an S5 with even better controlled, tamed bass, smoother highs, and more prominent mids, it should prove to be a hit with demanding listeners.
 

A better diaphragm with revised body and venting would go a long way in creating a superior S5.
 

Concluding Thoughts

 
Overall, the Brainwavz S5 is a rock-solid product. It's well-built and has good sound quality. With respect to sound signature, it hits the spot for the mainstream consumer looking for an alternative or upgrade to premium "fashion" headphones --- its sound is tuned for modern pop music, and it'll deliver satisfying music reproduction for most of the populace. However, I can't imagine the S5 being a permanent fixture in the collections of head-fiers. For the head-fiers out there, keep your fingers crossed for an "S5 Pro", or perhaps yet another model that can take on the iconism of the most revered. Until then, keep at it Brainwavz, and fight the good fight.
