Xenyx Q502USB : For the price you can't complain.

EDIT: After about a year of use, the device stops transmitting In an Output signals at random moments. The only way for me to temporarily fix it is to Unplug and re-plug the device from the USB port. Happends maybe once a day. Currently looking for a Yamaha AG03 as a replacement.

Very compact all in one design for people who want to do entry level streaming-gaming sessions, sound boarding or instrumental jams.

For it's small size it does have a lot more features and options then you would expect from an USB interface for this price. including mirrored playback for 6mm jack Headphones, built-in 1 band compressor knob, and the ability to attach speakers for both L and R channels for playback

HOWEVER. I do not advice this mixer if you are looking to do some Voice-overs, audio productions or live audio mixing with it. The maximum bit rate is 16-bit in which it sends the signal to your device... which is.. not acceptable for serious professional use-cases.

ALL the knobs that have to do with the volume: GAIN, LEVEL, COMPRESSION and MAIN. Do not have a middle step to feel where the middle ground is. I Personally do not prefer this on my buttons, as I tend to play with the knobs while recording, to get a feel of where the volume resides, without looking at it the actual mixer.

As all Behringer Xenyx mixers do... it also has an incredible annoying hiss when you amp it up to the maximum through your computer. However If you turn it down to 50% so that there is no artificial boosting it is not noticeable. I have only had this problem with Behringer mixers so far.
