Review on JBL Tune 215 - Wireless Bluetooth Earbuds with Mic/Remote and Flat Cable - White - Enhanced Audio Experience! by Ada Marcinkowska ᠌

The headphones are of a very poor quality. Clearly not in the realm of athletics. After the first serious run, sweat got into the case adjacent to the neck, and it covered the headphones. Assembly is the worst part of the process. In light of this, the fact that the sound quality has deteriorated since the previous release seems like a little matter by comparison. Cons: Poor construction, not appropriate for athletic use. The sound quality has worsened, and now only high frequencies can be heard. The block that contains the headset is constructed in such a way that when it hangs on the neck, the microphone hole is adjacent to the body and blocks the entire sound. In order to use it as a headset, you have to hang it with a button to the neck, which is completely absurd.
