Great sound, well built, and they fit really well. There are three sizes of silicone sleaves included in the packet. I am really satisfied with my purchase. I highly recommend these.

Very nice fit, surprisingly good sounding. Can't really fault at all.

Agree with everything said by Ross. Definitely no intention in the production of these to be "studio mixdown monitors", but for making a more "hi-fi" comparison in my studio against my monitors and my flat monitor headphones, these are fantastic. Big, bright sound, solid bottom end without being overblown. On stage, they have a brilliantly forward mid-high for vocals. At home, just listening to music, they're great. And all for 29 bucks. Will be getting more for the studio musos, and the band.

Great value in-ear monitors

I bought these initially to record my guitar amp, which is loud while playing at recording volume and I needed something to block out some sound and still hear what I was recording to. Works nicely for that and they sounds amazing, especially at this price point! I have been using them over a pair of over ear style headphones that cost 3 times the price. The sound is very detailed, with clear mid and highs, and the bass is impressive also. Punchy and has alot of presence without being to hyped like many expensive headsets do. They aren't quite a "flat" EQ like "monitor" style but pretty even across the sound spectrum. They come with 3 different pairs of earpiece rubbers so you can choose which ones fit in your ears the best. They are quite comfortable, I normally cant stand in ear style headphones but these are fine. Also comes with a clip to hold the chord to your shirt or belt etc, and the chord is split into two sections, making it safer if you pull it, it might pull apart rather than pull your hardware of the desk or pull the earpieces out of you head. Overall very impressed, am considering buying a few more sets for other band members and my home studio.
