The first test took me directly carved from the socks. The buds fit well, keep me bombproof and pairing via Bluetooth 4.0 with my HTC One M8 closed within a few seconds with the ironing! But what the headphones bring in terms of volume and dynamics on Pakett, is simply the "Hammer"! The sound is clear, powerful and vibrates my ear canals, which goes directly into flesh, blood and motivation in sports! I have rarely seen in-ears, I can not hear at full volume - these are what! Also worth mentioning is the well-executed remote function. It can be conveniently songs louder and make quieter, skip songs and take calls. The call function worked perfectly for me and was a lot of fun to make calls so!
I have often read that other buyers have had problems with disconnects. This I can not confirm as mentioned. I suspect that this may be due to outdated Bluetooth technology on the part of the mobile phone. With Bluetooth 4.0, I had a range of the 10 meters without loss! Even the battery life I can not judge as bad. She even almost exceeded in the first test, the specified 6 hours!
I can only say in conclusion that the 5 stars are fully deserved. Of course, the price is steep. But you get a top device for the price of what you is pumping the beat through his veins. As I have stated in the past often - Who buys cheap, buys twice. So I can only suggest to invest once and for having the best Bluetooth sports headphones that are on the market! In addition, have been falling earplugs during exercise hereby an end !!!
