HD-669 : Very good value for moeny

I bought this headphones for my recording studio few weeks ago and already used it in several recordings. Although they cannot be really used as the reference headphones they work very well as the recording monitors for musicians. I had number of musicians using it for couple hours and none of them ever complained about the comfort, signal level, noise cancelling or sound quality. Mixing on this headphones may be a bit difficult as they (in my opinion) have a bit too much lows (as it often is in budget closed headphones) and lack of clarity in mids, however please be aware that I'm comparing it to the DT-880 Pro and K240MkII that cost 10 times more. The difference between hi-end and HD-669 can be clearly heard but on the other hand they not that far from them in sound and build quality as they are in price which is very good thing. I have to say that so far this are the best budget close cups headphones I've ever had in my 20 years career. I would recommend it to anyone that need good monitoring headphones. They can't be beaten by anything else at this price tag.
