AUKEY Wireless Headsets Stereo Bluetooth 4.1 Sport Headphone

Please note that these are relatively new to me, if there is any change in opinion I'll come back and update. But I always make sure to burn in before I test and review any headphones, speakers or amps.

Build Quality & Fit
Designed to keep in line with modern trendy in ear monitors, expensive looking considering how cheap they are comparing to the price we pay for earphones in olden days. The plastic construction is of a decent quality and they are sufficiently lightweight to stay put once you have put them on. Most of the headphones the days come with three different sizes of rubber tips and they appear to be of higher quality.

These ear-phones use the Ear-Guides to hold the phones in place, therefore no need to run cables behind the ears. If you insert too tight, it will give you a muddy bass / closed sound. A nice gentle seal / shallow seal will give you the best sound quality. Take your time to fiddle around, try different earbuds and positions to get the best sound.

Technology
The version of bluetooth is 4.1 and this offers the advantage of faster connection to your devices. Extremely easy to connect to most of the smartphones (tested with iPhone 6S, Samsung S6 & Samsung Note 5). APTX will give you a very good quality audio over bluetooth. Tested with Samsungs' S-Voice, which works perfectly fine.

Sound Quality
This is really personal taste, but for me they are really good and worth a lot more than the actual price you pay for the headphone. Bass is just right but not overpowering the sound stage, open and clean. There are plenty of eq settings on your phone, so adjust accordingly so you will get the best out of these headphones.

General
Charging is easy. Micro USB cables are supplied. Comes with 24 month warranty.
