I would give the sound a rating of four stars, as it is not flat enough for higher listening levels on a computer, where tone controls may not be available. The construction quality also rates four stars, as the headband could be wider to distribute the weight better, and the cord, while plenty long at ten feet, one inch, is rather flimsy at only 3/32 inch thick, and it is not a user replaceable plug-in. The design rates four stars as well.
The earcups swivel both horizontally and vertically, and even fold inwards for storage in the included storage bag, along with the 6.3mm adapter plug. The leatherette on-ear pads are ok for short term use, but they are too thin, and the clamping pressure may require bending of the ends of the headband outward to make the headphones comfortable for long-term use, and the flimsy non-replaceable cord does not seem to be either designed or destined for a lifetime of heavy use, meaning these headphones are straying into the territory of the disposables.
Overall, we get a total score of 16 stars out of a possible 20 stars, or 80% (B-), and an overall rating of four stars. Are they worth buying? Yes...
