The speakers hiss in the background while playing, and it's quite noticeably, especially at medium volume. The sound is rich, but not clear enough (lack of treble?). In Bluetooth mode, there is no background noise.
When turned on, it always starts in Bluetooth mode, which is a minor downside but still inconvenient. The headphone jack is quite tight, but the worst part is that the sound through it is just terrible, with zero bass. Connecting the same headphones directly to the computer or phone gives a normal sound.
Bluetooth connection is okay. While listening to online radio from my phone, the connection would occasionally drop; maybe the smartphone was glitching, or maybe not, it's unclear.
Returned them back.
