BQEYZ its Summer! 3 way hybrid iem designed for hot hot hot!
Pros: A lot of drivers for your money
Good cable Good fit Go loud Made my Colorfly C10 usable for the first time ever - oh I'm so happy!
Cons: Won't suit bassy gear - Will need eqing for purists. Bass is bloated and sound can be fatiguing unless carefully matched

Close up showing proof of Summer


I decided to get this review done while the Sun is still shining in the UK. I have a shoutout first of all to BQEYZ. Thank you donating peoples of China. I would like to humbly remind people out there who care about my wealth and prestige; no sadly, this review package has not been sent with a boat or sports car or big ole gold chain. I am still not a richer man by receiving these - it's sad isn't it? They found me and they sent me these to get the word out - if it's not already out there, that is. If it is - welcome, you're no stranger here. If this is the first time you have heard of the BQEYZ Season range, where have you been? (Whisper stage left) - this is my first time too! Anyway, being no stranger to things small and pretty and shoved into one's ears - let's fly through this one - the Summer's not got long left!

Piezoelectric layer anyone?

BQEYZ Summer - an IEM, a hybrid job, and it hybridises Dynamic, Piezoelectric and Balanced Armature drivers. More so, this piezo is a 5 layer ceramic affair, so be assured of getting up into the audible threshold of a cat with the frequency response, which is measured at 7 (delivered by a 13mm dynamic using a couple of different materials) - 40 kHZ. 7 drivers - a well thought out combination, so a good start. The engine (the 7 drivers) is cased in a reasonably well fitting resin shell which has 3 concentric waves embossed onto each one. There is a BQEYZ logo machined onto the left and SUMMER lets you know which side goes into the right ear. The shell is concave along the entire inside diameter, rather like a huge bite taken from an apple.

20220903_083608-768x1024.jpg

This reduces the bulk of the design and allows for a smarter fit, as, of course, there is a big engine to get in under the hood. These IEMs are sensitive, at 107 dB, despite having a relatively high impedance, at 32 Ohms, and are as easy to drive as most of my similar IEM collection at around this price level. The price? This is as per amazon.co.uk as of going to press.

A nice, soft cable, which almost shimmers, comes with the Summer. It is a 2 pin IEM and can take a detachable cable, which we'll come onto later. The 8 strands make for a heavy cable, for most listening opportunities the ear hooks are finished well and the weight will simply pull the shell a fraction further down the outer ear lobe and remain there. In short, if you're sat down, you have nothing to worry about. Mine came with a standard 3.5mm jack, but other finishes are available.

Arty shot of otherwise sensible looking eartips

The eartips displayed above are the clears - there are darker ones supplied aswell. There are small/medium and large sets of each.

20220903_083455-768x1024.jpg
Being ware is to warn of escaping eartips. You now have been.

Beware! They are mounted upside down in the presentation case and are the darnedest thing to prise out, and then, of course, they fly off and head for the shadows and you can't find them! It only happened once (maybe twice) and it was only on the medium tips. As you can imagine, they were the ones I needed...Now - I preferred the darker ones; my thoughts were that they sounded "clearer" than the "clears", but that sounds daft doesn't it? More about that later.


What else is there, before we get to grips with the reviewing part? A fairly plain purple blue and white box with a less is more approach to presentation.

20220903_082835-768x1024.jpg
Here comes Summer

Opening the box up there is a false book inner which lets you know that you have made a wise choice in getting these earphones, so a big confidence boost there.

20220903_083026-768x1024.jpg
Wow! They know me!

Inside said box is a safety card, instructing you not to drive with these on; sensible words for sure.

20220903_084639-768x1024.jpg
Words of warning

The bottom half of the inner reveals a square PVC case and a stiff brush for digging out that stubborn ear wax and other routine cleaning and maintenance needs.

Build & Beauty


The finish of the shells is precise. Everything looks as it should and the quality control looks pretty much spot on. The fluted wave design didn't particularly grab me, as I hope it grabs you, because this, after all, a subjective opinion which places beauty firmly in the eye of the beholder.

20220903_083918-768x1024.jpg
The 3 wave resin shell

I get this feeling of familiarity with the cosmetics, and a slight disappointment that it wasn't more adventurous. The size of the shells is inevitably going to stick out slightly from my rather tiny ears, however the design has kept it reasonably well held until I start walking fairly hard and the effort makes my mouth and jaw flex and start to push the shells outwards slightly. This is nothing different to most IEM designs out there. Certain eartips will lock them in, even when down at the gym. They're not supplied as standard, but for those of you who need this info, you know where to get them. The case was the cheap Chinese one supplied with tons of cheap Chinese Gear, although this has had a mottled BQEYZ treatment, which lends it some authenticity. The case is better than nothing, but not very, for want of a better word; "Summery".

20220903_083421-768x1024.jpg
A case of mistaken identity? Surely I have seen such a case before?
The decals on the left and rights are ok - but again, I was left a little underwhelmed by the finish, I guess I was looking for something a little more unique to identify the brand.

20220903_083036-768x1024.jpg
The box - your prize awaits
These are all minor quibbles. I am happy for the Summer to redeem itself in the next, incredibly important, element of my inspection.


Sound character and quality


What does Summer evoke in you? The word Summer; ahhh.... gentle, slow days, sipping cocktails, smiles everywhere, beaches, bbq's. The best of days. Summer by BQEYZ has a lot to live up to my friends! The Summer is not a cold earphone; of that I can assure you.


The bass


The lower end is thick and meaty, like a great juicy slab of Tbone on those hot coals that keep your outdoor event going into the warm murkiness of an August night. The signature of the Summer is built around an extremely energetic sub bass, mid bass, and every other bass department there might be. This stridency brings an instant element of excitement; if you like your bass to have width and depth then you will not be disappointed here.


Vocals


The voice is surprisingly clear and therefore easy enough to follow on the Summer. I say surprisingly because the bass will not be interrupted; not for nothing! But there you go, that BA/Piezo lot have muscled their way in to the mix, and very welcome they are too.


Rhythm Instrumentation and Peaks


Following the beat on the Summer made a veteran reviewer like myself feel a bit fatigued, in stock mode, with no eq applied. Think of it this way; at least there's plenty of bass there. Turning it down in some way should bring the rest of the mix more into focus. More on that later. I keep saying that, don't I?

20220903_083327-768x1024.jpg
Slinky cable shot
The instrumentation can be judged against similar priced product out there and it reasonably holds it's own, it doesn't do anything particularly wrong apart from being a little harder to follow than some of the models I tested the Summer against, particularly in stock, non eq'd form.


The peaks were a little peaky. With so much bass going on, unsurprisingly, the rest of the mix needs a little extra to keep it audible. I found the highs a little shrill. Some of the busier sections felt a little flooded with too much sun, where shade perhaps could have been the more cautious, but less exciting approach. Judicious volume is required for the Summer - this iem can be tamed with a few, simple alterations.

How to get a great sounding BQEYZ Summer​


I suspect many of you have a favourite 2 pin cable, or, if not favourite, perhaps a cable that delivers less low frequency energy and more clarity in the mids and highs. I have an incredible Peterek copper cable that I just love. It took about 3 hours with the stock cable before I simply HAD to treat myself with the Peterek. Armed with a snazzier pair of Bermudas and I felt like I was squeezing a little more from BQEYZ, and why not? If you've got it, flaunt it! The beach body must be honed to perfection! Next up, I have some Spinfits. They have a better fit and are more leaner sounding than the stock eartips. My KBear Believe IEMs have been stripped naked by now, but I don't care! These hybrids need some help, and assistance they will get!

20220903_080110-768x1024.jpg
What a looker
Do you happen to have a slightly bass light Digital Device? The Colorfly C10 is my secret weapon for just such an eventuality. The C10 has a beautiful wooden finish, a horrible looking GUI, a mad impedance and won't even accept an IEM with a built in mic. With the bqeyz Summer is has found a perfect partner. Even with the stock cable and eartips, the sound of this match up had it all; timing, detail, separation, all in abundance. This is the best results I reckon I've achieved from the C10. It has finally come into its own.

20220903_082737-768x1024.jpg
A complement, a yin yang, a Laurel and Hardy
These are the tips I feel that produce the best possible results from these extremely capable earphones in terms of linearity and resolution; however, its Summer! Maybe you want to tackle a heatwave? At least for a while? For the time when you need to apply the after sun, read the above carefully, my fair weather friend.

The Supporting Cast


KBear Believe


20220903_081314-768x1024.jpg
Unbelievable
The sad withdrawal of these from the market has meant a lot of you out there never had a chance to see how good these are. There was some controversy surrounding the purity of the beryllium diaphragm. Rather than pursuing definitive testing, which would have proved economically unrealistic for a relatively small company, KBear felt the wisest choice was to stop making them altogether. The bitter irony here is that the title of the IEM certainly lived up to its name...

20220903_080824-768x1024.jpg
A photo of the case? My pleather
The resolution of the Believe is superb. I have customised it with the Peterek and the Spin Fit tips as mentioned earlier, and I am a great fan of this earphone. It is tough to fit into the sweet spot of the earlobe, and I'm forced to go unbalanced because of the Peterek cable's jack. The Believe needs lots of power to get moving properly; its a tricky feller. It is all worth it.

20220903_081644-1024x768.jpg
Plus a bit of Peterek
With all the stakes being equal (no eq, AK380, Peterek, Spinfits) the Summer cannot live with the stunning clarity of the Believe. The bass (which I know some of you will prefer on the meatier Summer) is leaner, faster, and extremely liveable over many hours. The character of the voice is in stark evidence with the Believe when compared with the Summer. There is no fatigue with the Believe despite the more evident micro detailing.

20220903_081759-1024x768.jpg
A bit more Peterek
With leaner equipment, the gap narrows wildly, so please, if you're into the lower end you must bare this in mind.


ACS Evoke


Think of the ACS as a mini marvel. They have an even leaner bass response than the Believe, they are tiny things that are almost invisible when worn and cut out huge amounts of background noise. They are extremely resolving, but the signature would take the newcomer some time to adjust to.

20220903_084351-768x1024.jpg
They're tiny but look big here
The linearity of these is way beyond the Summer on an even playing field, but everything must be right for them to come into their own; an AK380 with DSD files certainly helps bring out the best in these.

20220903_082159-768x1024.jpg
The wonky elegance of the AK380
Bring them onto the Colorfly and they don't perform against the Summer - they are a distant 2nd.


Shlouer Tape

20220903_084208-1024x768.jpg
Shlouer with more Peterek wires
The look of these is a winner for me, before I even wore them, I was determined they'd be great. They were, indeed, great! They're electrostat hybrids and the upper and mids are just great. The bass could be turned down a tiny fraction, but its not altogether too fatiguing. Against the rest, these were the best for mids. The silkiness of an electrostat is a great thing to hear, especially when its done well like this. The Tape was better in every department compared to the Summer, except when paired with the Colorfly. That was when the Summer came out to play properly.

20220903_084035-1024x768.jpg
Why won't companies copy this case?

Conclusion

20220903_082702-768x1024.jpg
My efforts rewarded
My time with you this Summer is fading. I have time to leave with a parting gift. There are many of you that will appreciate what these IEMs have to offer, but you will have to consider whether you have brought everything to the Beach Party to appreciate what BQEYZ have to offer. The Summer will need a lean source, or a tweaked eq, and benefits from better cabling and better eartips, but who doesn't? It fits well, but active users will need to look at other, grippy eartips. I am pleased to say I have found a place in the Sun for these, and for one, that makes me happy. Tequila Sunrise, anyone?

"Energetic Taste of Summer"

BQEYZ Summer.png

BQEYZ Summer is a tribrid driver configured IEM specifically a PU+LCP diaphragm DD, a 5-layer piezoelectric unit and
a custom-tuned BA. A really outstanding and overwhelming amount of drivers in one unit that certainly speaks with a huge amount of volume. Unfortunately, the Summer is not as prominent as the Autumn and Spring 2, but this IEM is no slouch and can definitely compete, I am telling you.

Before we start here's a quick DISCLAIMER:

  • I paid for this unit and got it from a friend. This is an independent review and is in no way affiliated with BQEYZ. Rest assured that this review will be free from any form of bias.
  • No monetary compensation is involved on the duration of this review.
  • This review are my personal observations, your preferences might not might match to mine.

Sources Used:
  • LG V20 (ESS ES9218 Quad-DAC B&OTuned (Global Variant))
  • LG V10 (ESS ES9018)
  • LG G8 ThinQ (ESS ES9218p Quad-DAC Meridian Tuned)

I used the stock cobalt-colored silicone eartips since I find it softer and comfortable than the clear silicone tips which has a harder stem compared to the cobalt eartips.

PACKAGE:

From the package, the Summer is encased on a flip box that looks like a smartphone box, it feels sturdy and the IEM just sits on a foam. Inside are the eartips, we have six pair of silicone eartips
ranging from S,M,L. A brush for cleaning the IEM, and a faux-leather case. What can I say but, not bad, I guess.

I'll give the packaging a 5 out of 5.

283612347_488758346380515_2694566161240256079_n.jpg


BUILD :
The Summer is using a clear lightweight plastic shell. I would actually prefer if my friend had the blue one so it would blend well with the clear silicone tips with blue stems, yet, the black clear shell ain't bad.
I can't say if the build is that durable since it feels plasticky compared to the Spring 2 (matte aluminum) and Autumn (metal, did not specify what metal, but I think its aluminum). So far, I don't have any issues on its sturdiness.
I personally think the resin used is safe from any paint chips, and dents compared to aluminum shells.

So, 4 out of 5.

281136824_491955159347441_2091944008930269872_n.jpg


SOUND:
At first, I didn't find the Summer to have a redeeming sound and was dismayed by it. Over the course of time I was dead wrong on my impression on the IEM and
the longer I listened to it, the more I learned to love the IEM. It's very detailed, lively, and clean. The first time these IEMs went to my ears, I gave it that this IEM has a V-shaped signature.

Lows :
The midbass is the highlight of the Summer in the lows department, it has a punchy attack with good extension. The sub-bass is not that prominent, rumbles and some earthy textures cannot be felt but is decent enough if you are not that much of a basshead.
This is definitely not a bassy IEM. It is just extended enough to make the IEM energetic. I did not notice any midbass bleed.

I'll give the lows a 4 out of 5 because of its energetic dynamics.

Mids :
The mids are slightly recessed, vocals are average. Instruments are clean, higher mids are crisp and airy. I cannot say anything outstanding to the mids, its just average for me. Vocals don't have that natural timbre, but it doesn't sound too artificial as well. It's just okay.
Given the V-shaped nature of this IEM, I understand why I don't find any "wow" on the mids.

Let me give it an average score of 3.5 out of 5

Highs :
Highs are well extended and elevated. The details on the highs are almost on point that its very satisfying. Crisp, airy, and inoffensive. However, first-time listeners on the Summer might find the highs harsh due to its
elevation. That's how I saw Summer the first time I tried it, but the longer I listened to the Summer the more I appreciated how the Summer retrieves small details with excellence.

I'll give the highs a 4 out of 5. It's inoffensive, free of sibilance, and well-extended.

Soundstage: Summer has good layering, the space between vocals and instruments has a decent amount of distance and positioning. Summer is able to decently pin-point these details making the listener focus and target a specific sound.

Imaging : Summer was able to reproduce the imaging that is able to differentiate between this and thats in the sound spectrum. Summer is able to handle busy tracks with decent precision.

281896923_7392925604116081_8166156662588754572_n.jpg

Conclusion

Is it worth to have the Summer? For $129, hmmm personally I would try to find another IEM first before blindly buying the Summer and see how it compares to other IEMs on its price range. But the implementation of LCP and Piezo is a new experience for me, it definitely
won't work out in the beginning but pair this with a warm source or so, it would definitely be worth trying. For driving this IEM, I think a phone can run it well, you don't need to use an AMP for it. I tried amping it, in the end I concluded that this could go without an amp. It's power hungry, yes,
but there is not a need for an amp to play this wonderful gem. An energetic and lively IEM, if that's your kind of sound preference then I would suggest the Summer.​

BQEYZ Summer Review!

Good day! After 4 days of casual and critical listening, here’s my written review for the BQEYZ Summer. Underrated!

Disclaimer:
  • I paid for this unit, with the help of sir Eiji of Euphonia Reviews and Ma’am Elle of BQEYZ Audio sent me this unit in exchange for an honest review. Rest assured that this review will do its best to devoid of any biases.
  • The following remarks and observations shall be made and owned only by me.
  • No monetary compensation is/was involved before, during, and after the period of creation of this review.
  • Your mileage may (and always, will) vary.

Burn-in time: 5-10 hours per day, 4 days.

Source/s used:

  • Hidizs AP80
  • Not-By-VE Avani Realtek Dongle
  • Zishan U1 USB DAC (AK4490 Variant)
  • Samsung Galaxy S3 (WM1811 DAC)
  • Non-HiFi smartphone (realme 5i)
  • Local Files via Foobar and Roon, YouTube Music, Deezer, and Qobuz with UAPP.

IEM and configuration: Stock grey medium ear tips, stock cable, any form of EQ or MSEB off, 40-60% volume, both high and low gain.

------------------------------------------------------------------------------------------------------------------------------------------

Sound signature:

  • U-shaped, energetic bright sound signature. It will sound w-shaped on some sources. Controlled, rumbly bass, clean, clear mids, bright and energetic highs.
Lows:
  • Lows are slightly elevated, and sometimes close to linear in terms of presence. Subbass and midbass quantities are almost at equal levels, with the sub-bass being slightly dominant by a very small amount. Decay leans to a slightly slower side of decay. Despite exhibiting a slow decay, the Summer managed to keep its bass controlled, clean, rumbly, and textured without sounding lacking on EDM or bass-heavy tracks. As a whole, the lows of the Summer are controlled, clean, rumbly, and can cater bass-heavy tracks you listen with it.
Mids:
  • The mids are almost linear, with an occasional slight recession on certain pairings and some tracks. Its presentation is very clear and clean with no presence of midbass bleed. Lower mids do not sound too thick or too thin. Upper mids are elevated and shows very good amount of sparkle and air. Instances of peaks on sibilant prone tracks are present but are on the tolerable side when compared to the other bright IEMs within its price range. Overall, the mids are clean, clear, and airy with a bit of upper mids peak.
Highs:
  • The highs are elevated and bright with very good extension. It also exhibits above-average detail retrieval as it the microdetails are easily heard and well defined on this IEM. As a result, the highs on the Summer can also please those people who are looking for a bright sound signature.
Soundstage, Imaging, and separation:

  • This is where the Summer excels the most: its technicalities. The soundstage is one of the widest I’ve had and heard, with very good depth and expansion. Separation is also excellent for its asking price as it handles most busy tracks with ease. Imaging is precise and has a very good presentation of spatial positioning of vocals and instruments.

Comparison/s:

VS TinHiFi T3 Plus:

  • The TinHiFi T3 Plus exhibits a thicker sound and bass response compared to the Summer. Both IEMs do not exhibit midbass bleed, but the T3 Plus has a recessed lower mids by a very, very small margin, like an inch or some sort. Upper mids on the Summer are much more elevated, sparkly, and airy when compared with some instances of peaks on sibilant prone tracks which the T3 Plus does not have. Treble is much more extended and brighter on the Summer, while the T3 plus leans to a more “organic” approach. Both IEMs exhibit very good remarks and performance based on their respective prices, but the Summer is better on technicalities when compared to the T3 Plus. I do have a finding that they share similarities on how they present their sub bass, probably because they share the same LCP Diaphragm as their DD material.
VS Audiosense AQ0
  • The Audiosense AQ0 is much more bass-heavy compared to the Summer. It also has a great amount of midbass punch when compared. The mids may sound lacking in detail on the AQ0 when compared to the summer. Lower mids are slightly thicker on the AQ0. Upper mids on the Summer are much more elevated, sparkly, and can introduce some peaks on sibilant prone tracks. The treble is also much more extended and detailed on the Summer. In terms of technicalities, the Summer is slightly better than the AQ0, taking the edge, particularly on the separation and soundstage.

Pros:
  • Nearly excellent sound quality for its asking price
  • Controlled lows that do not bleed to other frequencies
  • Rumbly sub-bass
  • Clear mids presentation
  • Airy and clear upper mids
  • Well-extended, energetic, and very detailed treble
  • One of the IEM that has the widest soundstage under 150usd I’ve heard,
  • Excellent imaging and separation for its price
  • Lightweight shell with very good isolation
  • 8-core cable already included as stock cable
  • Easy to drive but can benefit from a decent source.

Cons:
  • Instances of upper mids peaks are present on sibilant prone tracks
  • IEM design might not please everybody (subjective)
  • Heat shrink ear guides are a bit loose on my unit, but may not be the case for others.

Verdict

The BQEYZ Summer is an energetic, very good-sounding IEM for its asking price. I am a bit sad that this IEM went under the radar recently when in fact it can compete, trade blows, or even beat most IEMs within its price range, especially on how it showed its very good capabilities on its technical performance. On the other side of the coin, maybe the reason why it went under the radar is because of its upper mids peak that may not please most people, especially those who are very sensitive to bright upper frequencies. But for those people who can tolerate these peaks or are willing enough to do some extensive eartip rolling, I am glad to tell you that the BQEYZ Summer can be one of your choices for your next IEM purchase, as its technicalities are superb which you don’t see too often in the budget segment.

Thank you for reading!
