HD-681 Evo BK : Very capable cheap headphones!

These headphones are absolutely brilliant value for money.

The sound is very revealing. Mid bass is somewhat emphasized as with headphones like the ATH-M50, but it's not muddy enough to overwhelm. Excellent positional/directional accuracy and instrument separation. There wasn't a song I listened to that doesn't sound great through these headphones.

It's worth remembering that these are not closed headphones, they are semi-open. Sound will leak, both out and in. Best to avoid using these in noisy environments or when you don't want to disturb others.

Attractive shiny/matte plastic looks with a chrome accent, but the glossy plastic attracts a lot of fingerprints.

Solid construction with a replaceable cable - helps to prevent damage to the connection to the headphones themselves. (great, since this is what caused my last set to die on me after getting trapped in a swivel chair leg.) The self adjusting headband is easy to use but may need some time to stretch in order to easily fit bigger heads. (Like mine, unfortunately.)

They're lightweight, and can easily "disappear" and feel like you're no longer wearing them. The cable does however causes a lot of noise if dragged on clothing, etc..

Not exactly portable, but since these are studio headphones, and not really intended to be used when out and about, this can be overlooked. The inclusion of alternative velour earpads is a nice touch. It's down to personal preference, but I think they're much more comfortable and provide a better sound than the pleather earpads included.

Overall, these headphones compare very favourably to sets costing much more, and are definitely worth considering if you're on a budget.
