I was surprisiedly amazed how brilliant these headphones are very light weight they also very adjustable and flexible so you can put them in your handbag overall the build quality is superb the quality of the sound is crystal clear the bass is spot on the microphone pick up is very clear for conversations on your phone.
In fact, this is my first pair of sports headphones I've tried that has really worked properly! Fit in my ears perfectly and don't pop out and the weighted neck strap holds everything steady. The controls are easy to hand.
Even running they stay perfectly put, the earbuds block out plenty of ambient noise and the sound quality is great, much better than I was expecting with a punchy bass and clear vocals.
The best part about these is the battery life; 12 hours of pretty much continuous use is accurate.
Would definitely recommend for anyone wanting to listen to music whilst being active.
