The Superlux HD681 represents some of the top sound quality performance at this price available in the headphone industry.

Durably well-built and sweet-looking to boot, the Superlux cans are impressive stuff and recommended for audio pros, music-loving collegians and starter audiophiles!

We weren't really expecting much from the Superlux HD681 headphones  -- until we heard them. Sure, the bare-bones shrinkwrap packaging may leave something to be desired to the eyes but its the ears that will tell the tale of unexpectedly great sound emanating from these highly affordable headphones. The full-size around-the-ear earpad coverage, looping headband structure and semi-sealed earcup design may remind of the classic K240 look, but with a bit of additional low-end response present in the mix when compared to the traditional AKG tonal presentation. The Superlux HD681 also brings good focus and intelligibility to the midranges and vocal regions, all the more shocking for a headphone at this price. Although perhaps a bit bright in the upper highs, that could be considered a small quibble given the fabulous low cost of these all-around utilitarian cans. Designed ostensibly for pro studio and monitoring applications, the HD681's efficient 32 Ohm impedance also equaly suits portable and mobile iPad/ iPod / MP3 / computer listeners, even without a headphone amp along for the ride.

The Superlux HD681 headphones are true 'around-the-ear' cans with a non-detachable single-sided cable design. The earcups and headband assembly features nifty red color accents around the rims making for some nice, albeit un-flashy sprucing up of the cosmetics. The bearcup constrcutioin is semi-sealed so exopect only mild-to-moderate attenuation of ambinet noise. The advanatge of the semi-sealed earcup is it does protect against headphone audio "leakage", critical if doing any close-mic vocal or studio work.The Superlux HD681 headphone cord extends about 8ft and comes terminated to a 3.5mm 'mini' plug; a full-size 1/4" stereo adapter plug is contained in the Superlux package along with soft travel pouch / storage bag.

Great headphones!
Posted by CLYF from Clovis, CA on 2012-01-26

Recommend Product: Yes
Pros: Inexpensive, comfortable, 1/8-1/4 adapter, acoustic dampener, adjustable spring-mounted strap
Cons: Starts to hurt temples after about 5 hours of constant use (Don't judge me)

There is nothing bad to say about this AT ALL! Another reviewer was complaining about the peak in high-frequency sounds... Not for me. Maybe you are wearing your headphones back wards because the acoustic dampener covers only one side.. The side that is there when you wear it RIGHT. If I HAD to say something bad about this, it'd be that after about 5 hours of constant use, it can begin to make your temples sore. But that is all :)

Ear killer sound
Posted by Zobel from Montana on 2011-11-08

Recommend Product: No
Pros: inexpensive
Cons: screeching highs

Wow! These almost sound great! If they didn't have the hole in the mids followed by such a big peak in the upper treble, you could enjoy the bigger than life, somewhat bloated bass. As they are though, they are loaded with detail, and unfortunately, way too much upper treble to be something I want to listen to. I'm not willing to do the capacitor mod to these, since comfort is marginal, construction is pretty cheezy, and I'm not sure it would work anyway.
