Intro
TL;DR: Brainwavz' first foray into Bluetooth IEMs – the BLU-100 – is definitely a respectable one, with a smooth, bassy signature that easily appeals to most listeners.
Before I begin, I would like to thank Audrey at Brainwavz for providing a review sample of the BLU-100 in exchange for my honest opinion. Please note that I am neither an affiliate of Brainwavz nor any of its staff, nor am I being paid to write this review. Also, please take all following opinions with a grain of salt. All opinions expressed in the following review are strictly my own unless otherwise specified, and all pictures are taken and owned by me.
Wow…okay, so it’s been quite a while since I last got a review up. I’ve been pretty busy the past weeks that I haven’t been able to write something up in so long. By now, however, things are finally getting back in full swing, and DB Headphones is back in business!
Anyways, this week we’re yet gain taking a look at Brainwavz’ latest offering – a Bluetooth IEM. Now, to audiophiles like me, Bluetooth is by far the last thing we would take a look at if we’re looking for a new earphone or headphone by sound quality alone – the wireless audio transmission at this point just isn’t advanced enough to provide the same audio quality wired connections offer (just like how wired is better than wireless in gaming peripherals). But having already seen what Brainwavz is capable of doing, I was more than interested in taking up Audrey’s offer to review these new IEMs. Will they stand up to their wired counterparts? Read on and find out!
== Aesthetics ==
Packaging, Accessories
The package I received was a pre-production package, so I didn’t get to receive the BLU-100 inside full retail packaging. However, all of the accessories which are to be found in the retail release are all here, which includes: · 3 pairs of silicone eartips
· a pair of Comply S-400 foam eartips
· a pair of silicone fins (more on this later)
· a USB to Micro USB charging cable
· a nifty Velcro cable tie
· and their signature red-and-black hard zipper case
As always, Brainwavz delivers with an impressive amount of accessories which are sure to prove useful even outside of the BLU-100’s main uses.
Design, Build, Microphonics
 |
| The Micro USB charging cap. |
Brainwavz employed full-metal housings for their BLU-100 IEMs, which is particularly impressive especially at their retail price of just under $50. The cable, although a little thin, feels quite solid and is properly relieved at both ends. Its three-button remote is situated by the right earpiece, and the Micro USB charging port is situated in the right earpiece, protected by a plastic cap. Build-wise there’s little to complain about if at all.
However, the BLU-100’s housings do leave me wanting. I don’t particularly like their barrel-shaped housings, not just because they look rather crude, but because they stick out of one’s ears quite a bit, which makes them very uncomfortable when laying on one’s side. A good example of what I’m looking for is the Plantronics Backbeat Go 2, which prevents that problem while still retaining a sleek, compact form factor. There’s also its flat cable, which, despite having little to no cable noise, is quite long and does trail around my back quite a bit – to make matters worse, there also isn’t any cable cinch to keep the excess cable at bay. Of course, these are all just personal gripes for me, but the bulky housings can translate into fit issues for some people (luckily I don’t happen to be one of those people).
Fit, Comfort, Isolation
The BLU-100, as I stated earlier, fits perfectly fine in my ears, staying secure while running or playing sports. The BLU-100 employs a shallow fit, which translates to somewhat below-average isolation. Then again, once the music starts playing, that doesn’t become much of an issue. They’re also quite comfortable in my ears with the Comply foam eartips, although I can’t really say the same for the silicone eartips as they don’t really create a proper seal in my ears. However, I found that I get headaches from the BLU-100 after only 15 minutes of listening. I still haven’t pinpointed what causes this, although at this point I’m guessing it’s the housings themselves, which seem to be completely unvented – and that’s a pretty big deal for a couple reasons (see side note below).
(Side Note: Why is the BLU-100’s unvented design such a big deal? Well, the BLU-100 employs a dynamic driver, which is in layman’s terms your common IEM driver. However, dynamic drivers require at least some degree for ventilation for proper airflow as these drivers move air by design [just like speakers and headphones]. Without proper venting, the only air it moves is the one left inside your ear canals – and with the existing pressure inside the ears, it can cause undue pressure in them, which translates to the headaches I suffer while wearing them.)
Specs
Headphone Type | Closed-back Bluetooth in-ear monitor (straight-down only) |
Bluetooth Features | Bluetooth 4.0 HFP, HSP, A2DP, and AptX support CSRBC8645 chipset |
Operating Range | Up to 30 feet/10 metres (Note: this figure only applies to a perfectly open space with the BLU-100 having a direct line of sight to the source device. It does still reach a comfortable 20 feet inside a more closed-in area.) |
Battery | 60 mAh rechargeable battery (charged via Micro USB port) 2 hours charging time |
Battery Life | 4 hours music play time 4 hours talk time 100 hours standby time |
Accessories | Hard carry case 3x set black single-flange silicone eartips (S/M/L) 1x set black silicone fins (M) 1x set Comply S-400 premium foam eartips (M) 24-month warranty |
Features | CVC echo and noise cancellation (microphone only) Battery indicator (iDevice-compatible) 2-device memory Voice prompt user-interface: Power On/Off | Pairing | Connecting | Battery Low |
The BLU-100’s specs are mostly a hit for me – for one you’ve got Bluetooth 4.0 with AptX support, which is good, but on the other hand you’ve got a measly 4-hour battery life that makes the BLU-100 only end up being more of a burden than a convenience if you’re looking to use it all day. Outside of battery life, though, they do have pretty impressive features and specs that you only find in Bluetooth sets set at much higher price points than the BLU-100. Take the Backbeat GO 2 I mentioned earlier as an example – they’ve both got pretty similar specs, but the GO 2 is priced at $100 – over twice the price of the BLU-100. So when you take that into consideration, the BLU-100 is actually much better than it is at first glance.
Connectivity
The BLU-100’s pairing process is particularly straightforward. Hold the centre button until it powers on and continue pressing it for 1 or 2 seconds. A voice prompt will say “Pairing,” then will transmit a Bluetooth signal which your phone should be able to see. This is what it looks like on the Bluetooth selection screen on my iPod:
I’ve highlighted the BLU-100 in red and as you can see, it’s named BD-121 (That could be because it’s a pre-production unit. I don’t really know why.). Just select it from the list of devices and you’re good to go!
The signal of the BLU-100 has been choppy, from reading other reviewers’ opinions. However, I personally haven’t experienced those random drop-outs myself. Only the common phone-in-your-pocket drop-outs happen (which is a normal occurrence) but otherwise they perform without any major problems.
== Sound ==
Equipment, Burn-in
The source equipment I used for this review is my iPad 3 and a 5th-generation iPod Touch. As the BLU-100 is a Bluetooth IEM, there are no amps or DACs in between. The eartips being used in this review are the included Comply S-400 foam eartips. The EQ software being used is TuneShell (a free app) running on the iPad 3. As always, my test tracks are available here, although I will link specific songs in the assessment for a more direct point of reference.
The BLU-100 has been given at least 50 hours of burn-in prior to writing this review. So far, I haven’t noticed any differences in the sound, so without wasting any more time, let’s get right to it!
Sound Quality
The BLU-100 has a pretty generic sound signature, taking the form of a consumer-oriented V-shaped sound that you hear in at least 60% of all headphones and IEMs out there. Honestly there’s really nothing new from a general overview, but listen in closer and you’ll find some things that separate them from your usual fare.
Bass:
First off, let’s start with the bass. The BLU-100 delivers quite nicely in this regard, with an impactful punch which should satisfy most consumers’ bass criteria – however I wouldn’t go so far as to say they’re basshead-friendly (Fox Stevenson – Manage). In any case, the low-end is pretty focused around the mid-to-upper bass (60-100+ Hz), which makes them sound overly full and warm (Daft Punk – Fragments of Time). Then again, they do still have quite a bit of detail down there, which really surprised me as the BLU-100 managed to reproduce the heavy bass notes on this next song (Daft Punk – Lose Yourself to Dance) fairly well.
Midrange:
I’ll be honest, I was quite surprised by the midrange performance of the BLU-100. Despite being a very consumer-sounding earphone, Brainwavz still managed to wring out some degree of clarity to the midrange, rendering vocals and instruments about as well as the wired and slightly more expensive Brainwavz S0 (Eagles – Desperado). To be honest, I would actually go as far as to say they sound slightly better than the S0 thanks to the BLU-100’s more pronounced treble.
Treble:
Speaking of treble, let’s talk about that. The BLU-100 has a nice, crisp treble that brings out just enough snap and sizzle for cymbals, claps, and high-energy synths, but also remains nice and smooth, never going to the point where they get irritating to the ears. The treble also adds a nice tactility to pianos, which otherwise would’ve turned them into a confused mess of notes (Yiruma - Reminiscent).
Soundstage/Presentation:The BLU-100’s soundstage is what you would expect from an IEM at $50, but in a compact Bluetooth package. Here it again draws a parallel to the wired Brainwavz S0 in terms of soundstage and imaging capabilities, both of which perform very well. The BLU-100’s got an average soundstage and good separation, which helps with more complex recordings (Daft Punk – Touch). However, don’t expect too much out of it.
Genre Proficiency:
These Bluetooth IEMs actually sound pretty great with a wide variety of genres. From soft piano recordings to heavy dubstep and metal, they manage to sound just right for just about everything. Probably the only areas the BLU-100 fails to perform to expectations are recordings with a lot of instruments playing at the same time (Coeur de Pirate – Metal Gleamed in the Twilight), where the Bluetooth IEMs couldn’t really capture the dynamics and the emotion of the recordings.
Summary:
Otherwise, though, you really can’t go wrong with the BLU-100, sound-wise. For a sub-$50 wireless IEM they provide a sound quality that one would find comparable to wired sets at the same price. Its V-shaped sound signature will most definitely appeal to the average consumer, and works well with just about any genre one would listen to. I’ll admit, Brainwavz made some pretty good calls in tuning the BLU-100’s sound, as honestly I have little to complain about despite the IEM being wireless.
Other Media
Games:Being a mobile-designed Bluetooth headset, it’s outright impossible to use these to game on a PC, unless you have a Bluetooth dongle that could pair and output to the IEMs. In any case, I wouldn’t say much here, other than that they could make a decent “beater” pair for gaming. It may not give you any edge over the competition, but hey, even the “competitive” mobile games (i.e. Clash of Clans and similar games) don’t even need positional audio to play – heck, you could even put the game on mute and still play just about as well as the next guy.
Movies:
The BLU-100, with its easy-going, consumer-friendly sound signature, should do fine with movies. They’re not the best, but they’re definitely not the worst, either. If anything, the bass reproduction is a little off-mark for me, as their focus on the midbass takes away emphasis on the rumble and more emphasis on the “boom,” which in my book is a definite ‘no.’ Otherwise, there’s nothing they do absolutely wrong so as to make them unlistenable.
EQ Response
I found the BLU-100 to be pretty responsive to EQ, settling down to a sweet balanced sound signature with a few quick tweaks. The curve kinda looks like this:
…which, as you can see, looks rather similar to the “Spoken Word” preset in the iOS system equalizer. In any case, I found these tweaks worked out very nicely on the BLU-100, leaning the sound towards the balanced signature I look for. However, do note that using standalone EQ apps often drain your source battery life, and on top of the drain caused by the constant Bluetooth signal chain, you will want to watch your battery levels more closely.
Value
Now past the pre-order stage and now in full production and release, the BLU-100 is available on Brainwavz’ parent company MP4Nation for $44.50 (Link). I’m pretty sure I’ve mentioned this many times throughout the review, but with the BLU-100’s features and performance, they are an absolute steal at this price. That’s all I can say.
Comparison
Versus Brainwavz S0 ($50)
As I’ve also stated earlier in this review, I thought of the BLU-100 as a parallel to the wired Brainwavz S0, and for good reason: they sound quite alike. However, they each make clear sonic distinctions which make them unique in their own ways. The S0 is smoother, darker, and more laid-back, while the BLU-100 is livelier and more energetic. Personally I find the BLU-100 to have a more enjoyable signature, as their treble offsets the IEM’s warmth and bass very nicely.
Versus Plantronics 903+ ($100)
The 903+ is an old, discontinued Bluetooth headset with a sport-oriented earhook design which has now been replaced by the current Backbeat Go 2. My dad would often use these earbud-type earphones on long cycling trips, which allowed him the convenience of hands-free conversations over the phone. The great microphone, as well as the 7-hour battery life (both of which I skimmed earlier) really edges the 903+ over the BLU-100, but for an earbud fit at twice the price? No thanks.
== Conclusion ==
I’m not a fan of Bluetooth technology, as “convenient” as going wireless is. There are just way too many caveats that pull me away from ever using it over a regular wired connection. But I’ll admit the Brainwavz BLU-100 changed my position on that slightly. The BLU-100 is a great example as to why I love Brainwavz as a company. They create products with features you need at prices that give the more expensive sets a run for their money. Sure, it may not blow competitors out of the water, but for a sub-$50 package, you will want to think again.
Category | Score | Comment |
Packaging, Accessories | 7/10 | The BLU-100 is, again, showered with Brainwavz’ trademark accessories package. As I didn’t receive the full release version I can’t say anything about the packaging. |
Design, Build, Microphonics | 7/10 | The BLU-100 has pretty much everything going for it in the build department – housings, cable, and all. However, it does lose out a bit for me design-wise with a few mainly personal gripes. |
Fit, Comfort, Isolation | 7.5/10 | The BLU-100’s included Comply foam eartips provide a great, secure fit and excellent comfort. The isolation, however, is quite a bit below average, so you will want to use aftermarket eartips to block out more external noise. |
Connectivity | 6/10 | Despite frequent reports of drop-out issues, I found no such problems with my pair of BLU-100s. It works pretty solidly and performs as advertised. |
Bass | 7/10 | The BLU-100’s bass is something I think most non-audiophiles will find satisfying to their tastes. Decent impact, okay extension, and a clear focus on the midbass show that this was designed for the consumer in mind. It’s definitely not “audiophile-grade”. |
Midrange | 7/10 | I’ll admit, the BLU-100 has a surprisingly good midrange, featuring a nice amount of clarity and a smooth, warm tone. It’s something that just works. |
Treble | 7/10 | The treble really rounds out the BLU-100’s sound signature, with a crisp response that wrings out the tactility in vocals and instruments. It also balances out the bass very nicely. |
Presentation | 6.5/10 | The BLU-100’s soundstage is about as average as it gets. Decent size, decent width, good separation. It’s good, but definitely not amazing. |
Gaming, Movies | 7/10 | I found they work pretty great with watching movies on the iPad, with its 4-hour battery life outlasting a good movie or two (unless you’re having an LotR or Sherlock marathon). Gaming-wise it’s something I wouldn’t recommend, but then again, who plays FPS on mobile? |
EQ Response | 7.5/10 | The BLU-100 is quite responsive to EQ and shows noticeable improvements with very slight tweaks. For iOS users, the “Spoken Word” preset is recommended. |
Value | 8/10 | I think it’s obvious that the BLU-100 shows excellent value for the money, with a complete package that goes up against wired sets at around the same price. |
Total | 7/10 | The Brainwavz BLU-100 is the definitive budget Bluetooth IEM, with features and accessories that go head-to-head against Bluetooth headsets at twice the price. Brainwavz did very well in creating the BLU-100, never cutting corners in providing you with great sound at a very reasonable price. |
Suggestions for Improvement
- Improve tuning next time around. However, I don’t have any gripes sound-wise other than the focus on the midbass. Less of that = a more balanced and more audiophile sound signature.
- Might want to improve the battery life as well. Maybe kick it up a couple hours or so on a more expensive model in the future.
