Sonically the headphones are good, and I would like to see a little more bass. Here it should be the equalizer for music (if any) slightly higher if necessary in the smartphone app. The sound representation for audiobooks is excellent, I have in this regard Audible Amazon in use. Surprisingly good I find the possible use of TaoTronics Bluetooth headset as Bluetooth Headset. The speech intelligibility for me and for the other side is excellent, however, a noise canceling (noise suppression) does not exist.
Ear studs are due to design some getting used to. Especially when running sports everyone must try for yourself here if it fits. Various earplug sizes are included. The small control unit, in addition to the practical charging socket for microUSB a +, a - and a play button with the regulated volume and songs can be changed forward or backward. In this part of the way, is also the microphone for the hands-free system.
* My Opinion: A convenient Bluetooth headset for people who do not feel like dangling cables. But sonically they should for this price do not expect high-end and the ears fit would depend on the particular carrier, for the gym and at home it's okay for me. Because of my view still favorable price-performance ratio I forgive even 5 stars.
Note: Bluetooth devices must be connected prior to use only with their smartphone (pairing). This device is placed on pushing the play button above in pairing mode and can then be connected from Android or iPhone.
