Brainwavz are back yet again with another product set to offer what the big boys do but at a far more wallet friendly price point.  This time the company that brought you the stunning value earphones and headphones are taking aim at the in-ear Bluetooth market with their new earphone the Delta BLU.  An area traditionally dominated by Jaybird.  In the past I have found most cheaper priced, similarly styled earphones to be severely lacking in both build quality and connectivity issues but have high hopes for the BLU-Delta as a budget standout. So with this in mind and the emergence of wireless technologies in almost every facet of life that I take a look at these Brainwavz and see how they stack up.

Inside the box:

There are no doubts given the good quality packaging and branding on all other Brainwavz products will be present in the final version and the BLU-Delta earphones are no exception.  What I can say confidently however is that at the very minimum the accessories provided to me will be present in the final version.  In that regard we have various sized ear-tips of which, as usual, the small size was the best fit for me.  There is a set of official comply tips which a nice added bonus when you consider these Bluetooth earphones are to be sold for just $44.95.  There is a small Micro USB cable to charge the earphones with but in reality, you can use any standard micro USB cable from your phone etc.  Finally, there is the standard red and black Brainwavz branded hard case to keep the IEM’s safe.  Brainwavz always do accessories well and yet again that is the case with the new BLU-Delta.

Build and Appearance:

First off the build of the BLU-Delta is stellar.  Side by side with the other Bluetooth earbuds they feel far more robust with their solid all metal housing that will be able to take a beating.  The cable connecting the earphones together is also very nice being flexible enough without compromising on durability.  The inline remote section is simple but again well-built and its nice they made it compact even though it adds some weight on the cable.  The features on the remote cover volume up and down as well as power functions and with some button mapping you can even skip tracks via double taps. The styling of course is partially dictated by the B housing containing Bluetooth receivers, a charging point and a battery so they are definitely bigger than most conventional dynamic driver earphones.


Really, really well actually.  It couldn’t be simpler; all I did was hit the power button on the earphones inline remote and then I searched for new devices on my phone.  The BLU-Delta popped up immediately, I hit connect and I started playing music.  No hassle, no messing about, they just worked. There is a small LED ring built in so you can tell when the unit is on which is welcome but it could be a brighter for viewing in daylight. In over 2 hours of use I didn’t experience any dropped connections.

Battery life is short at only 2 hours, that’s fine if you are commuting back and forth for an hour or so a day but you won’t be able to get a full day use. For those looking for a set of gym earphones (an area I think Bluetooth is best suited), from battery life side these aren’t the best around.

The earphones sound rather good for one that relies on the limitations of wireless technology. It’s a warm and bass centric presentation which definitely can’t be described as bright or sparkly.  If you are a treble head or enjoy a bit of sparkle, then best look elsewhere.

It’s not quite a stock generic consumer sound though as there is quite a decent amount of separation and clarity to the BLU-Delta.  On a personal note this is exactly the type of sound I would want when working out which is, as I mentioned, is a market where the BLU-Delta should see a lot of success.  There is a good amount of thump in the bass as well as energy in the midrange to get you up and motivated and the absence of elevated treble means you shouldn’t suffer from fatigue on extended listening sessions.  Those who listen to a selection of rock, pop or Electronic music will be those that will enjoy the warm sound of these Brainwavz earphones as they managed to perform well for a set of sub $50 earphones in those areas.

Wrap up:

In all honesty, there is very little to dislike about the Brainwavz BLU-Delta earphones when you see just how much you are getting for the price of $49.50.  Its incredible value and they are not far off of the performance of other far pricier model. The sound will suit the majority of the public with its emphasis on the mids and low end. Operation of the unit is extremely simple and its very well built.  Accessories are plentiful and practical.  It’s all very good but think of it this way instead.  There are plenty of earphones you could spend $50 on that sound good in their own right but none that I can think of that offer all the features listed at such a low price
