Much higher output level than my other (older) LD In Ears. I use these just for back-up or where additional IEMS are needed with my wired units. The Bass response is ok, however they also sound much brighter/ harsher in the upper mids and can be tiring after a while. For the price I can't expect much more, but had hoped for a warmer tone similar to my Sony, which where not much more expensive. The cable is of good quality and feels reliable.
What I don't like is the lack of "touch" identification for L&R identification in low lighting on stage, such as shape or something. So I'll have to make a small marking to identify this. not a problem, but would have been nice to already have that. Also, a 90˚ jack would have been a plus :-)
