SUPERLUX HD681 Series Monitoring Multi Sound Profile Over-Ear Headphones

•The Superlux HD681 represents some of the top sound quality performance at this price available in the headphone industry. Competing against --- and handily beating -- many other more expensive headphones, the Superlux HD 681 is a marvel of great value meeting top audio detail resolution power. 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!

•The Superlux HD 681 are very similar to the Superlux HD 668B in shape and sound. They're a bit more comfortable, thanks to the different headband design that's not as tight on the head. They also sound better than many pricier headphones.

•The Superlux HD 681 are a good budget option for neutral listening. They have slightly more extended bass than the Superlux HD 668 and deliver a satisfying audio reproduction that caters well to instruments and vocals. They have a relatively flat mid-range

•The Superlux HD 681 look very similar to the Superlux HD 668B. They have practically the same ear cups but a different headband design, making them look more like the AKG K240 MKII. The color scheme is pretty bland, but this model stands out a bit thanks to the red accents on the ear cups and headband.

•The Superlux HD 681 have good consistency performance. The bass range performance is very consistent across human subjects, except for the one subject who wears glasses, as he gets 3dB less bass than others at 20Hz. The treble range consistency is also very good, especially below 10KHz.

•The Superlux HD 681 have very good mid-range performance. Low-mid and mid are virtually flat, but under our target by about 2dB. This pushes vocals/leads slightly to the back of the mix, giving more emphasis to the bass and treble ranges. High-mid shows a small tilt favoring higher frequencies, but the effect will be very subtle.

•The Superlux HD 681 have decent treble range performance. Low-treble is well-balanced but slightly inconsistent. Treble has a 10dB bump between 7KHz and 12KHz, making the sound of these headphones noticeably sharp and sibilant.
