I've had this for a few months so now is a good time to write my review, my cell volume to max is 15 and with this device I don't have to push it past 5 ( using the 4.4 mm that I mostly use ) build is really good, it has some weight to it, the sound quality is really good it adds a bit of base, the thing I hate about this is that depending where you are in the city the feedback is horrible it will even cut out, what helps with this is a longer type c2c like a foot or longer cause the 3 inch one that it comes with is trash, so if I'm home I'm 100% happy with it, out side the house it's hit and miss. Over all I am happy with it, but it has its issues 8/10
