not good for proper DJing as they have not much bass output but thats not really what these phones are for. Occasionally drops connection completely for ~5 seconds. I plan on updating this review after my nieces wedding next weekend and a birthday boat cruise the weekend after. Easy to install if you know HOW to install it - only gave that 4stars. However, I expected to get a new pair, not sandals that are already somewhat run down at the heel; the previous owner must drag their feet, lol. After my 1st time wearing them, for 2 hours straight. However, I needed a microphone that would have a long distance and 360 degree sound pickup range, that could inteligently filter out background noise and background chatter. Bought these for my son for a month long trip to the Carribean. I originally wanted a lighter shade, but got the Mocha Birkibuc color because of the great price and I?m very happy with them. Am gewicht bemerkt man schon die Qualität, die man von Bose gewohnt ist.
