Star scores are based on the price range.
Obviously there are better ones out there but not anywhere near this price!
These are great budget units that have a good full range response and I don't see them as being overly harsh in the high freqs are others have reported. I mixed some recording with these the other day and the results sound very similar through a good quality hifi system.
Lightweight, comfortable with plenty of adjustment, I used them for a 3 hour session and had no problems with comfort. Seem pretty well built but only time will tell I guess.
For the money totally recommended, don't be put off by the price or 'brand name'
