BA Timbre
The Fearless S8F was my first serious purchase in the chifi several years ago. It was my maiden foray into the detailed segment of the IEMs in general and boy, was I hooked. It was one of my most cherished IEMs until I knew better - more on that later.

Unboxing/Packaging
I won't dwell on this one very long because, back when I bought the S8F, it was a "new" IEM and Fearless did not have the fancy box - rather it came in a plain cardboard box. Inside the box there was a black plastic hard case, which housed the IEMs, some tips, a 3.5mm terminated cable, a cleaning tool, a plaque with Fearless certification.

Sound Impressions
Firstly, if you are a detail junkie and if you love highly resolving IEMs, this (was/is) it! However, the caveat is, if you are extremely treble sensitive, I guess this won't be your cup of tea. Now, I will discuss briefly on the separate elements of the SQ.

Treble: This is the highlight of the IEM. The treble is where it truly shines, and really hits the standards (and often outshines some $1000-$1500 IEMs, I'm looking at you EE Zeus). Very detailed with great separation of instruments. However, as pointed out, seldom it could be a bit tad too much (for me). So, if you are looking for a lush, laid-back sound - these are not it. If you want all the micro-details, then this top end does it and in a grand style.

Mids: The midrange has an overall clear presentation. Vocals come out with great clarity and guitar riffs really has the proper bite one would expect from rock tracks. I did not find any sort of veiling which several renown BA IEMs suffer from.

Bass: Okay, this I feel is the where I really wished the IEM could have a bit more bass shelf. Although I truly love the IEM, some more midbass presence would really serve well on heavy metal and rock tracks - which predominantly encompasses my library. Don't be misled though. It has great extension. The lows go really low, but it would shine most in well recorded jazz tracks in my finding. But if only a bit more bass could have been thrown in, it would become more of what it already is - an extremely detailed monitor.

Resolution, Soundstage and Imaging: The imaging is stellar. It rivals the likes of the IER-M9 which is known for its great instrument placements. I could point out every instrument in David Chesky's Rock Re-imagined album - which btw. I feel everyone should listen to. While the separation and detail was stellar, there was not as much air between instruments that one might find in Campfire Andromeda or Sony IER-M9. Lastly, and most importantly, in the resolution front, this specific IEM really cemented Fearless as a serious player up there with Campfire, Empire Ears, JH Audio - only to name a few.

Why I sold it: Well, let's face it, IEMs have come a long way since the S8F in a very short time. Hence, it was inevitable. Moreover, because of the fatiguing treble, longer sessions were getting painful. So, it had to go. Moreover, the Blessing2 exists now for a more modest price-tag. I hope it served as an inspiration to the next home, as it did for me in the audio journey.

Concluding Thoughts
I believe this is the landmark IEM that made me take notice of what is happening in the east. If there was not a successful S8F, I believe the Clairvoyances, Monarchs and SA6's of today would not have come to fruition. One thing to take notice is, I mentioned the likes of Sony, Empire Ears, Campfire Audio in this short review; which essentially is big praise in my book. If you would ask me to describe the S8F in one sentence, I'd say "It is close to to the Empire Ears Zeus XIV - for better or worse."

Pros: Overall tonality
Bass (for a BA)
Great detail retrieval
Treble (for some)
Good midrange tonality
Isolation
Cons: BA Timbre
Still BA Bass
Intense/shouty
Hello everyone.

I would like to preface two things.

Firstly, I do not completely believe in audible “burn in” or cable changes (in regard to sound). I have not personally been able to detect any changes in sound with a different cable or hours of burn in. My review however will be based on my final impressions after 20-25 hours of burn in with the stock cable and stock tips.

Secondly, my music preferences consist of many genres ranging from Rock/Metal, Rap, J-Pop/K-Rap, and some acoustical/vocal based music.

*Note I have switched out Wage War for Polaris.
Sample songs used to evaluate gear:

Polaris – Casualty, Hypermania, Vagabond
Slipknot – Before I Forget, Duality, Psychosocial
Hoshino Gen – Koi, Continues, Sun
Mariya Takeuchi – Plastic Love, Yume No Tzusuki, September
Jakubi – Holiday, Pillow, Nobody Better
Gorillaz – Clint Eastwood, On Melancholy Hill, Ascension
Tupac – Ambitionz Az a Ridah, Changes, All Eyez on Me
Mos Def – Mathematics, Hip Hop, Ms. Fat Booty
Polkadot Stingray – Free, Mermaid, A Stinging Spica


Etc.

Overall tonality: Aggressive V-shape.

Fit: Small-medium sized shells. Slightly bigger than the Theiaudio Legacy 3/4, but much smaller than the Blessing2

Comfort: Quite comfortable. Shells barely stick out of my ear. Occasionally I do feel pressure do the nature that these are not vented. As a note, I do have smaller than average ears.

Cable: Quite nice looking and sturdy. A little too heavy and hurts the back of my ears.

Isolation: Above average. Not as isolating as an Etymotic but much more than the DK2001.

All critical listening was done off the Topping L30/E30 and LG V30/Radsone ES100 using Flac files or Tidal premium. Casual listening was done with Spotify. This was purchased with my own money.

Bass: Being an all BA setup, it shouldn’t be a surprise that bass is not as impactful as a dynamic driver. Subbass is lacking extension and doesn’t have a that satisfying tactility and texture of a DD. Midbass seems to have a bump giving off a more “thumpy” response. This works well and doesn’t ever bleed into the mids. Luckily, the overall bass response is quite fast giving off the impression of a clean bass. Surprisingly though there’s a decent amount of rumble. Subjectively, I find the bass to be a little lacking energy and dynamics. Objectively, I think the bass is very well done and offers a generous bass boost. I think this will only offend those looking for a purely neutral set and bassheads

Mids: Despite it’s V-shaped signature, the mids are not really recessed and sound natural for the most part. Vocals often come across as a bit shouty, but never shrill. Although this can be great for certain genres and listeners, this can cause fatigue for longer listening sessions. I find that female singers in particular come across this way, while male singers tend to have more body. Luckily, string instruments have a good sense of body and presence, guitars in particular fit this description. I would consider the mids tonally accurate, though not very forward (minus vocals).

Treble: The treble is elevated making these desirable for those looking for treble oriented iems. My main critique is the intensity it has. Although never sibilant, the forwardness of the treble will either be a deal breaker for some, or exactly what others are looking for. Cymbals and hi-hats can often become fatiguing though the emphasis gives them an energetic tone to it. The treble can be considered “sparkly”, but perhaps a tad too forward for some. The treble provides a good amount of air giving instruments a great sense of depth

Soundstage: Surprisingly wide and spacious. Not the "three blobness".

Imaging: Similar to soundstage. Positional accuracy is excellent.

Resolution: Very high-resolution set.

*It should be noted that the S8F does exhibit BA timbre. Not horrible, but noticeable.

Select Comparisons:


Sony XBA-N3AP

The N3 is quite the opposite of the S8F. Significantly more bass, more natural mids, and less detail/technical performance. The S8F prioritizes its treble resolution, decent bass response (especially for an all BA setup), and detail retrieval. The N3 has been my go-to “fun” set, while the S8F is the more suited for shorter, aggressive listening sessions. The S8F exhibits BA timbre while the N3 sounds quite natural in comparison. The N3 wins in comfort due to its smaller size, though the S8F isn’t far behind. I believe in the 4.5/5 score for the N3.



Moondrop Blessing2


This is an interesting one. At a cheaper price tag, the Blessing2 competes head to head with the S8F, in my opinion. The bass response can be considered neutral on the B2, while still providing enough presence on certain tracks. The S8F has a significant bass boost in comparison only lacking that DD rumble that the B2 provides. Midrange on the B2 is rather thin in comparison but relatively forward in the mix. The S8F has the more natural, but recessed midrange in comparison. Vocal presentation on both can be considered a little too shouty. Treble is where the S8F pulls ahead. The B2’s rolled off treble lacks detail and extension when compared to the S8F. Staging and imaging are quite comparable on both. The S8F exhibits more BA timbre while the B2’s BA timbre is not as significant. The B2 loses in comfort. I believe the B2 earns a score of 4.5/5 (too lazy to make a review. There's also so many out there)



Dunu DK2001


Similar signature but done differently. The DK2001 has a more satisfying bass emphasis while also having great midrange tonality. The midrange on the S8F provides more detail when compared to the DK2001. In contrast, the S8F specializes in treble and is much more detail oriented. The only aspect the DK2001 outclasses the S8F is in its bass response. The S8F wins in every other aspect (midrange tonality, treble resolution, technicalities etc.). The DK2001 is more comfortable and fits better for my small ears. I believe the DK2001 should be revised to a score of 3.5/5 (not sure to edit a review though).



Conclusion

For its $489 base price, the Fearless Audio S8F offers an attractive proposition. While it is a significant jump over most <$200 chi-fi iems that I have tried, the competition is getting fierce with offerings such as the Blessing2 (Dusk). Being the most expensive IEM in my collection, expectations rise and reviewing becomes more critical. While I do believe these to be excellent sounding with a few potential dealbreakers, the price bracket is currently in may or may not be the deciding factor of its recommendation. For $319 you can get the Blessing2 (or stretch to $329 to get the Dusk) and get an exceptional sounding IEM that rivals, and frankly outperforms the S8F in some respects. With that being said, the S8F is a competent IEM for those looking for an aggressive v-shaped signature.
Pros: Build, fit comfort, overall balance and tonality (for a V shaped IEM), bass quality
Cons: Struggling to find any at this price point

INTRODUCTION

One of the IEM choices I’ve been looking for over the years is an all BA IEM which can maintain balance and tonality, whilst providing high isolation. This has been a difficult search for me, as there are many different ideas on what constitutes balance. As such I’ve tried many multi-BA IEMs which have come close, but not quite met the standards for my personal preferences. I was contacted earlier this year by Head-Fi’s “listen4joy” who sent me his pair and asked if I’d review them. Did they tick my boxes for balance and tonality? Lets find out.

DISCLAIMER
The Fearless Audio S8 Freedom that I’m reviewing today was provided to me as a review loaner. It will be returned following the review. The retail price at time of review is ~ USD 489 (Penon Audio).

PREAMBLE
If you haven't read any of my reviews, I suggest starting here, as it will give you an insight into my known preferences and bias

For the purposes of this review - I used the Fearless S8 Freedom straight from the headphone-out socket of many of my portables, but predominantly the M6, M9, M11, and R2R2000. I have also experimented with a variety of amplifiers including the FiiO Q1ii, E17K, Q5, and xDuoo XP-2. IMO they do not benefit greatly from additional amplification. In the time I have spent with the Argent, I have noticed no change to the overall sonic presentation (break-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 PACKAGE
The Fearless S8 Freedom arrived in a 125 x 180 x 50mm box and lid, surrounded by a printed black and white sleeve. The sleeve has a leaf pattern on the front, and lists the S8 Freedom’s specifications on the rear. Opening the box and lid reveals a cleaning cloth, envelope with documentation and blue hinged lid carry case (70x125x40mm) which contains the S8 Freedom, cable and tip selection (along with a contact card).
9941911_l.jpg

The full accessory package includes:

  • 1 pair Freedom S8 IEMs
  • 1 x 2 pin stereo cable
  • 1 x hinged lid carry case
  • 7 pairs of “Fearless” silicone ear tips
  • 1 pair of dual flange silicone ear tips
  • 2 pair of foam tips
  • A card with serial number
  • Envelope with information in Chinese
  • Cleaning cloth

This is a reasonable accessory package, and in-line with the overall asking price.


THE TECHNICAL SPECIFICATIONS
9941906_l.png


MEASUREMENTS
The graphs I use are generated using the Vibro Veritas coupler and ARTA software. Ken Ball (ALO/Campfire) graciously provided me with measurement data which I have used to recalibrate my Veritas so that it mimics an IEC 711 measurement standard (Ken uses two separate BK ear simulators, we measured the same set of IEMs, and I built my calibration curve from shared data). I do not claim that this data is 100% accurate, but it is very consistent, and is as close as I can get to the IEC 711 standard on my budget.

I do not claim that the measurements are in any way more accurate than anyone else's, but they have been proven to be consistent and I think they should be enough to give a reasonable idea of response - especially if you've followed any of my other reviews. When measuring I usually always use crystal foam tips (medium bore opening) - and the reason I use them is for very consistent seal and placement depth in the coupler. I use the same amp (E11K) for all my measurements - and output is under 1 ohm. Measurements above 9-10kHz are generally problematic with any hobbyist set-up, and should be disregarded, but generally my measurements from 20Hz to 9-10kHz have proven to be relatively close to many of the measurements of the manufacturers who support me.

The graphs are provided merely as a point of discussion, and later in the review I've included comparisons to other IEMs for similar reference. Channel matching is as good as I’ve seen on any IEM I’ve tested and is consistent over the entire frequency range.

BUILD
External
The S8 Freedom has the type of shape synonymous with higher end customs, and is a peanut/jelly-bean shape design. It is designed to ergonomically fit snugly inside your outer ear cavity, securely held inside the Concha with the skinny end inside your Intertragical notch. Just like true customs, it has a small rise of resin at the rear of the IEM shell to comfortably accommodate placement over the Crux helix and sit intact on the Cymba.

9941915_l.jpg
9941916_l.jpg
The outer shell material is a highly transparent resin with a blue tint. The internals are easy to see despite the tint (which i really like). The outer face is clear with the Fearless Audio logo on the left earpiece and model name “Freedom” on the right. The internal face is very smooth, and not utilising a dynamic driver means no requirement for an external vent or port. The housing has an and end to end length of 24mm, height of 16mm and depth of 14mm (excluding the nozzle). The nozzle is angled nicely forward and up, and is 10mm in length (including the flare at the base). The nozzle diameter is 5.5-6mm, has no lip, and has 3 separate sound channels in the tube.
9941917_l.jpg
9941918_l.jpg
At the top rear of the S8 Freedom shell is flush fitting recessed 2 pin (0.78mm) socket. The 2 pin cable plugs are colour coded (blue or red) for right and left. The socket is very firm with the supplied cable and feels very sturdy. The S8 Freedom comes with a single ended SPC (silver plated copper) cable. Its is an 8 core braided design. 4 braids on each side combined to an 8 core braid beowo the Y-split. The section below the 2 pin plugs is encased in a soft transparent shrink tube which naturally forms an ear hook. The Y-split is metal with a matching neck cinch, and the jack is 3.5mm, straight, and rhodium plated. The cable is really well built, and comfortable to wear.
9941919_l.jpg
9941920_l.jpg
Internal
Internally the S8 Freedom uses an all Balanced Armature driver system. The interesting thing is that they’ve chosen to use a combination of drivers from both Sonion and Knowles for their tuning of the S8 Freedom. They use dual Sonion BA for ultra-low frequency, Sonion dual BA for low-medium frequency, dual Knowles BA for medium-high frequency and dual Knowles BA for ultra-high frequency (a total of 8 BA drives). They’ve used a 4 way active crossover and 3 sound tubes.


FIT / COMFORT / ISOLATION
Internal and external isolation is extremely good (26dB), as you’d expect for a non-ported IEM. It does ultimately depend on tip choice and seal. I would rate passive isolation as well above average and usable on public transport. Although it does not completely block out aircraft drone, by the time you add music, you aren’t hearing cabin sounds.

Fit and comfort thoughts are very subjective, and will vary from person to person. My experience has been one of complete satisfaction. The S8 Freedom has been designed for an ergonomic fit (much like a custom monitor). For me they are a perfect, sit flush with my outer ear, and basically disappear within a few seconds of wearing (I could forget they are in). I have slept with them intact, and woken hours later with them still there and no discomfort. The S8 Freedom is designed to only be used cable over ear.
9941921_l.jpg
9941922_l.jpg
The S8 Freedom has a no lip on the nozzle, but the nozzle itself is relatively thick, and quite long. With my preferred foam tips, I have no problems with the tips coming off the nozzle – they are quite firm. I also tried my usual medley of Spiral Dots, Spin-fits, Ostry tuning tips and Sony Isolation tips – all fit easily but can slide off in your ear if you get a good seal. So really – would prefer some sort of shallow lip – a slight design flaw. They are a relatively shallow fitting IEM, but the nozzles are long enough for most tips to seal effectively. Foam still gives me the best combination of seal and comfort and these also remained very secure on the nozzle.

SOUND QUALITY
Most of the testing at this point was done with my FiiO M11, no EQ, and Comply foam tips. I used the M11 simply because paired they gave me a very transparent window to the music with low impedance, and more than enough power.

For the record – on most tracks, the volume level on the M11 was around 35/120 on low gain (depending on the track) which was giving me an average SPL around 65-75 dB. Tracks used were across a variety of genres – and can be viewed in this list . While testing I constantly switched with my reference pair (Alclair Curve + E17K with +4 bass) to give me a good reference base-line. The additional bass is to bring the Curve closer to reference.

Relativities
  • Sub-bass – In balance with upper mid-range but sitting above lower mid-range – definitely above reference. Extension is extremely good and the sub-bass rumble is definitely audible (Lorde's “Royals). Surprisingly there is minimal bleed into other frequencies. The bass is a-typical of most BAs I’ve heard. It is quick with clean decay and good speed, but more impact than I am used to.
  • Mid-bass – slightly below sub-bass but above lower mids with medium impact. The bass timbre and definition is quite clean and clear, and this is bass quality and quantity that most people should enjoy. With Eminem’s “Lose Yourself” I was surprised at the amount of impact the S8 was able to deliver whilst still maintianing clarity.
  • Lower mid-range – recessed compared to bass and upper mid-range. There is a definite V-shape here. Both male and female vocal fundamentals are still very good though. Male vocals still come across with good body, and I’ve really enjoyed the likes of Eddie Vedder (Pearl Jam) and Shaun Morgan (Seether). The mid-range recession also gives a little impression of space and separation.
  • Upper mid-range – There is a slow and shallow rise from the lower mid-range to a peak at 3-4 kHz, then a relatively extended progression to the lower treble. The transition from lower to upper-mids is cohesive, and there is enough presence to provide both detail and presence. There is some euphony with female vocals.
  • Lower treble has a small peak at 6-7 kHz, and then drops a way a little through 8-10 kHz. The peak at 6-7 kHz still gives some nice detail and brilliance with cymbals, and the drop-off maintains smoothness and makes sure there is no brittleness or sharpness.
  • Upper treble appears to extends quite well but is below the rest of the signature. It is difficult to capture properly on my measurement rig, and with my “aged” hearing I no longer notice much over 12 kHz anyway.
Overall this is a reasonably well balanced monitor with a “V” shape which has more to do with the slight recession in mid-range (intended) than any obvious emphasis at either end of the spectrum.

Resolution / Detail / Clarity

  • Slightly elevated bass response gives a little more bass guitar than truly balanced, but doesn't hide or mask detail.
  • Very good cohesion in the mid-range, but appears very slightly distant compared to some of the more mid-forward earphones I've listened to lately. This is not necessarily a bad thing
  • Clean and clear in the presence area with very good detail especially around vocals and guitar.
  • Very good upper end detail (hi-hats/cymbals) with good decay – no signs of being over done. Just enough heat to balance things nicely.
  • No signs of lack of resolution – some who prefer brighter presentations may find these a little on the smooth side.
Sound-stage, Imaging
  • Good directional cues, just outside the periphery of my head space – so reasonable feeling of width and also of depth.
  • Imaging is clean and clear and very good separation of instruments without being clinical. No signs of smearing.
  • Good immersion (applause section of “Dante's Prayer”) with impression that crowd is around you (you are sitting right in it). Good sense of depth as well – although width slightly stronger.
  • Live recording of Lakme's “Flower Duet” (Netrebko and Garanca) had very good presentation of space – especially as the singers move from front to rear of stage.
  • Sibilance is present in “Let It Rain” - I know it exists in the recording. Not enhanced or over-emphasised.
Strengths
  • Speed and impact of both sub and mid-bass.
  • Reasonable sense of stage
  • Good for both female and male vocals.
  • Nicely euphonic upper mid-range
  • Detailed and clear with no brittleness
Weaknesses
  • Nothing springs to mind. This is a really easy to listen monitor with good mix and cohesion considering the mild V-shape.
AMPLIFICATION REQUIREMENTS
The S8 Freedom doesn’t need amplification for overall volume – and because its impedance is a relatively low 15 ohms, a source with an output impedance of around 0-2 ohms (to meet damping requirements) should make the best match. Most good sources should easily sit in the 0-1 ohm range.
9941925_l.jpg
9941926_l.jpg
With the M11 around 35-40/120 low gain volume covers my normal 65-75 dB listening level. With M9 the range is 38-43/120 for the same listening volume. The S8 Freedom is pretty easy to drive, and even the diminutive M6 has no problems driving them and sounding extremely good to boot. Next up was amplification, which meant testing with the Q1ii, E17K, Q5, and XP-2. In each case I noted a slightly different tonality but noticed no real differences in dynamics on any of the additionally amped sources. The XP-2 (via bluetooth) added some extra warmth which was not ideal for my tastes, but IMO the S8 Freedom can do perfectly well without additional amping.

RESPONSE TO EQ?
Personally I find the S8 Freedom pretty much aligned to my personal tastes with regard to default signature. To test EQ ability, I used the M11’s built in EQ to give a slight cut to bass and whilst the S8 responded well, I preferred the default. I also boosted the upper treble at around 8-10K using the M11, Neutron and a parametric equaliser. Again – the S8 responded well to the change – but in all honesty I can’t see myself using EQ with this IEM. Fearless Audio got this one pretty right.

COMPARISON WITH OTHER IEMS
These comparisons were all done with the M11, (no EQ) – and volume matched using a calibrated SPL meter and fixed 1kHz test tone first. For this series of tests I’ve tried to look at both value and quality – pitting the S8 Freedom against other IEMs in a similar price category. For comparison I’ve used the FiiO’s FA7, FH7, Audiofly’s AF1120 mk2 and Dunu’s DK-4001. This is pretty subjective, but the graphs do show relativity against the other IEMs for reference.

Fearless S8 Freedom ($489) vs FiiO FA7 ($300)
9941927_l.jpg
9941909_l.png
Build fit and comfort
The FA7 is quad BA vs the S8 Freedom’s eight. Both have an ergonomic shape and both fit perfectly. Both are well crafted from resin and have well made replaceable cables – with the S8 cable being more pliable. In this comparison, the S8 takes the points for cable, but both are equal for comfort, and ergonomics.


Sound & Value
These are chalk and cheese. FiiO tried to add some warmth to their signature, and elevated the bass – a lot compared to the mid-range. The mid-range (if you cut the bass) is almost perfect, but in its default signature, it is overly warm, lacks definition, and is highly bass emphasised. The added bass bleeds into the mid-range, and it sounds cloyingly dark. Thankfully Fearless were able to add the bass while retaining clarity and balance. A good example of tuning both bad and good. Here the S8 wins by a mile and is well worth the additional money.


Fearless S8 Freedom ($489) vs FiiO FH7 ($450)
9941928_l.jpg
9941910_l.png
Build, fit and comfort
This pits a 5 driver DD/BA Hybrid vs the 8 driver all BA S8 Freedom. Both IEMs have ergonomic shells and are very comfortable for long term listening. Both also have replaceable cables. Comfort and build quality here is shared. Personally for me, fit is slightly better on the S8 (longer nozzle) and the S8 wins inn terms of isolation.


Sound & Value
There is some similarity with these two IEMs, but the differences shown in the frequency response don’t quite show the true story. The perceived bass of the FH7 DD is closer than the graphs show vs the S8’s BA delivery (the S8 does have more overall impact though, and is quicker). Mid-range is somewhat similar, but the main difference comes with the more forward mids of the FH7 vs the more classical slow rise of the S8 (from lower mids to upper mids). Both are clean and clear though, and both pretty well balanced. The FH7 is a little leaner whilst the S8 is a little more laid back. My preference here is the S8.


Fearless S8 Freedom ($489) vs Audiofly AF1120 mk2 ($700)
9941929_l.jpg
9941907_l.png
Build, fit and comfort
The AF1120 mk2 is a 6 driver BA vs the 8 driver Freedom S8. Both IEMs have extremely ergonomic shells and are superbly comfortable. Both also have replaceable cables, although the S8 Freedom’s is arguably better quality. Comfort, isolation and build quality here are shared.


Sound & Value
Somewhat similar overall tonality. The AF1120 has better end to end balance, and although the bass looks lighter, the balance with the rest of the signature doesn’t make it sound bass light at all. Everything in a signature is relative. Both have very quick transients and do detail really well. The S8 Freedom has more emphasis in the lower end and a smoother overall tonality. The AF1120 has the better end to end balance with a slightly brighter top end. I really like both, and the winner here depends on the tonality you’re looking for.


Fearless S8 Freedom ($489) vs vs Dunu DK-4001 ($899)
9941930_l.jpg
9941908_l.png
Build fit and comfort
The DK-4001 is a 5 driver traditional hybrid vs the 8 driver BA Freedom S8. Both are extremely well made with ergonomic shells and replaceable cables. The DK4001 is a multi-jack modular cable which is extremely well designed, but I still prefer the overall ergonomics of the S8 Freedom cable. The S8 Freedom is a little more comfortable overall, and naturally has better isolation (being port-less).


Sound & Value
These two are again quite close in overall signature (remembering the DK-4001 has DD vs BA for the bass). Both are clean and clear. The S8 is warmer and smoother while the DK-4001 is cooler and brighter. I really like the sound of both IEMs, but based on overall value, the S8 pulls a little ahead (if this is the type of signature you’re looking for).


VALUE
This is an easy one. The S8 Freedom sits in a price bracket which a few years ago would have been higher-end, but nowadays is recognised as more of a value segment. And it really delivers. The signature – while coloured and definitely V-shaped – is also well balanced and very well tuned. Add the stellar build and you get a pretty complete package. While I wouldn’t call them sonic diamonds, I could easily have these as one of my primary IEMs and be very happy.

FEARLESS S8 FREEDOM – SUMMARY
I’d heard about the Fearless S8 Freedom before I had a chance to review them, and was somewhat suspicious about some of the hype. Often when you read nothing but good things about an IEM, you naturally question whether the hype train is running amok. In this case (IMHO) the hype is justified. The S8 is a very good IEM at a reasonable price point.

The tuning is not one I’d necessarily gravitate towards, but it does have great balance, and the bass tuning is both tasteful and not overdone. It definitely has more kick than I was expecting – but its fun and exciting without being overdone. The great thing about the tuning is the detail which is still present, and the overall tonality is really pleasing. Female vocals are excellent.

Add to that the quality build, cable and the comfort, and you have quite a package. For $489 they are not cheap – but IMO they do represent value. I’m actually toying with the idea of buying a pair eventually – just because its one of those signatures which is actually quite appealing.

My sincere thanks to listen4joy and also the team at Fearless for allowing me to review the S8. I can definitely recommend this IEM.

Any noise with M11? Totally black or acceptable amount? In my experience they hiss with all more potent sources.

I didn't notice any noise with the M11. It has less than 1 ohm OI from the SE port.

I reviewed the S6RUI previously here. Since the build quality, fit and comfort are nearly identical, some text is directly pasted from my S6Rui review.

Build Quality- S8F shells are 3D printed and made up of resin. They are crystal clear and you can clearly see the drivers inside which have the model number, ‘S8 Freedom’ inscribed onto them. The faceplates now spot the new Fearless logo. The shells do not have any bubbles and the seam between the faceplate and the bottom shell is flawless too. The 2-pin sockets are recessed which enables part of plastic before the 2-pins of the cable to go in. The sound bores in the nozzles have been drilled very neatly too.

The 2-pin 8 core cable provided in the package has an attractive silvery white color and feels very well made. It’s not the most flexible cable but it has a very good feel to it and isn’t microphonic. Impedance of the cable is around 200-250mΩ.

Fit and Comfort- S8F has an extremely comfortable fit for me, probably one of the best I’ve tried under $500. I get a very snug fit with excellent isolation for a universal fit. All the curves of the shell are well polished and feel nice around the concha of the ear. It is also very comfortable to wear for long durations of time.

Sound Analysis – S8F has an analytical tuning which is high mid and treble dominant with good bass definition and clarity. It is an intense listen where you’ll be immersed in details and sounds, keeping your attention peaking at all times. It certainly isn’t an easy listen like warm or smoothened out IEMs. Let’s dig deeper into the specifics.

Bass – The bass is unlike what you expect from standard multi-BA IEMs. It is well present with fast attack and decay. The notes are well defined and the lower range can go deep when it needs to. It isn’t abnormally boosted and songs like Karnivool’s Goliath are a fun listen. The bass tone sounds gnarly with good definition. But the focus is still towards treble and high mids and the bass presence might not satisfy the needs of the 'extreme' basshead inside you. Tending bassheads who love a maturely tuned bass will be happy with the S8F.

Mids- The lower mids take a back seat here. They aren’t overly recessed but the higher mids are more dominant to demand your major focus. That doesn’t mean that the lower mids aren’t good. The lower mids are done well enough to keep the snare’s body and deep vocals sounding great but the snappiness of the snare and sparkle in the vocals take a slightly larger piece of the pie. The detailed higher mids also give the S8F its prominent character.

The peak around 4.5kHz makes S8F intensely detailed. You’ll hear lots of micro details and quieter sounds that you would’ve earlier missed in smooth and warm sounding IEMs. The S8F highlights nuances even in relatively smoother songs like John Mayer’s ‘Gravity’ and ‘Slow dancing in a burning room’. The spring reverb in the latter ripples through the heart (being a little over dramatic like John Mayer for affect, Lol!).

Vocals and acoustic guitars sparkle! That’s exactly how they sound in the S8F, sparkly, clear and very detailed. If the singer smacked his lips between lines, you’re going to hear it. S8F gives you a spatial image of watching the singer perform in a small concert hall. I re-watched John Mayer’s live concert film ‘Where the light is’ and his intro acoustic segment with songs like ‘In your atmosphere’ and ‘Free fallin’ gave me gooseys and kept me smiling with satisfaction. I could even hear Mayer fanboys clearly (along with the obvious fangirls), screaming their heart out in between songs. Hmmm… Haha

Treble – The treble is as detailed as the high mids. S8F sounds quite open and airy without getting harsh. Snares have good stick attack and cymbals are present but not strident. Vocals, acoustic and electric guitars get further help from the treble in sounding clear and detailed. But on the flipside, if you aren't used to heavily detailed IEMs, the S8F can get a bit intense and might fatigue your ears out in longer sessions initially. Once you get used to them and your ears adapt, the fatigue will vanish. I being a musician wanna know everything that’s happening in a song with every detail highlighted, so I love and enjoy this character a lot. Also, on the bright side, the detailed sound signature enables me to listen to songs rather clearly at low volumes, which is quite cool because generally if the IEM doesn’t sound as detailed, one tends to go straight for the volume button to compensate for the muddiness, leading to dangerously loud levels. This makes S8F quite safe for your ears considering loudness levels. All in all S8F's treble is energetic and makes listening to songs fun and exciting at all times.


Soundstage, Imaging and Separation – S8F has a wide soundstage, wider than most IEMs I’ve heard in its price range and it is all thanks to its clear and detailed sound signature. Imaging is on point and instruments are placed quite accurately. Separation between instruments is one of the best I’ve experienced in this segment. All in all, no complaints here.


Comparisons –

S6RUI vs S8 Freedom

S6RUI Solo.jpg

Think of S6RUI as S8F’s sibling who is younger by a year (2 drivers). S8F sounds airier and creates a better sense of space. It has more sparkle and snap in the 2-6kHz region. The mids are relatively thinner and have better resolution. The bass sounds more authentic, tighter and cleaner but both S8F and S6RUI have good slam! Personally, for me, the S8F sounds more exciting with better resolution overall.

But on the other hand, S6RUI is warmer of the two and an easier listen. If you don’t want as much resolution and prefer listening to an easier sound signature, go for the S6RUI. But if you want a more detailed and resolving IEM, S8F is the one.


Conclusion – S8Freedom is another winner from Fearless. I’m lucky to have been sent 2 of the most popular models, S8F and S6Rui, and I found both to be quite interesting while still serving slightly different audiences. S8F with its energetic, lively and detailed signature gives the obsessive listener enough reasons to be happy and not much to complaint about. Fearless with their pricing, attractive customization options and various sound signatures across different models are out there to serve the various demands of enthusiasts and are certainly a company that you should know and look into when your hands get itchy for the next purchase. I can cross my heart and recommend the S8 Freedom with full confidence.

Any comparisons with any high end flagships like Legend X, U12t or Solaris? Or any other IEMs you may compare retailing over $1000. Just trying to consider how competitive is it with high end iems.

Hi Brooko. Do you have any suggestions for an EQ to take some of the brightness awayfrom the FH7? Regards, Darren
