The HD-681 headphones from Superlux combine premium-quality audio components with an ergonomic design to offer accurate and detailed sound in a lightweight and comfortable package. Ideal for long, fatigue-free listening sessions, they are intended for use by musicians and audio professionals in monitoring applications, including recording live instruments and vocals, mixing, and more.

The HD-681 features around-the-ear earcups which provide sound isolation from outside noise and help eliminate "headphone bleed" when recording in the studio. The semi-open design delivers a natural sound while still offering deep bass response and minimal sound leakage. Two 50mm neodymium drivers provide a rich, balanced sound with high resolution, wide dynamic range, and excellent stereo imaging.

The headphones are equipped with a self-adjusting headband and thick around-ear cushions, providing the listener with a great fit. The HD-681 comes with a protective storage pouch and a gold-plated 1/4" adapter.

Worth the buy!
Size: Medium, Color: Black
These socks wash well and have lasted us through the year without holes wearing in them. This is actually the 2nd pack we’ve purchased and will definitely buy more when we outgrow these.

Highly Recommend these as daily socks
Size: X-Large, Color: Black
I love these socks. I’ve been wearing for years. There was a batch I purchased about 2 years ago that all fell apart in the same seam location after 6 months but UA appears to have resolved. I highly recommend.

They're ok, miss the resistor 3.0
Size: Large, Color: Black
I bought these because Under Armour stopped making the resistor 3.0 socks. These are fine, but the resistors are better. This model is a little too form-fitting, and I have to make sure they're situated on my toes properly, otherwise they'll sit between my little toe and the next one.
