It's 600 ohms and not sensitive in the least. It has a one-foot cable with a coil that will snap your neck if you attempt to extend it. It has vaguely rectangular earpads that an ear can neither fit in or rest on top of the ear. It's made by a company the specializes in batch orders, "education" equipment, and 5.1 sets. It has the build quality of a 1980's Chinese child's toy, which is fitting since the production of the headphone probably dates back that far. It has too much sideways bulk to be viable to use while moving, though the cord keeps you tethered only inches away from your source anyways. Its aforementioned rectangular pads are made of a magical plastic that is at once rough and slippery. And, not the least of the worries about it, it sounds absolutely horrid. I give you, the Hamilton Electronics HA-5!
Listening to Duke Thompson was an experiment in how many frequency ranges can go completely missing on a headphone. Piano and brass was there one moment, and gone the next. In addition, the former instrument had a harshness about it that I've never heard from any other headphone. Each litte note, wherever on the piano it fell, turned into high-pitched screechiness within a split second. Putting on some more modern music (Jonsi's Go), I experienced a new level of sonic pain as instruments and electronic sounds mushed together. It was unbearably loud and harsh, yet at the same time had such a detachment that the headphones seemed underpowered by a full system. This is truly the worst full-size headphone I've ever had the displeasure of listening to.
And the worst part? I still can't stop coming back for more.
