I wasn't expecting too much for $25, but was pleasantly surprised. They have a surprisingly full sound. If the song has lots of base you can't crank it. You will hear distortion. But for normal listening levels they're great. I forgot my phone upstairs and it worked flawlessly when I went into the basement. It dropped a few times when I walked further away but still was listenable. I would definitely recommend them. I should mention that I have a Galaxy Nexus. I can answer calls and people can hear me fine. They don't ask if I'm on Bluetooth like other Bluetooth devices I own. I haven't been able to get the voice dialing to work though.
