Superlux HD681 over-ear headphones with 50mm drivers and 3.5mm jack

The 50mm neodymium drivers and wide 10Hz–30kHz response are intended to bring depth and detail to music, games and home-studio listening. The Superlux HD681 is an over-ear wired model with a 3.5mm jack and a screw-on 6.3mm adaptor included.

Its self-adjusting headband and earpads are designed for comfort during longer listening sessions. The listed impedance is 32 Ohms, with a sensitivity of 98 dB.

Looking for one pair for both music and gaming rather than a specialist headset? The HD681’s broad stated frequency range and versatile positioning are relevant, though it has no listed noise control.

Highlights

The product description points to deep low frequencies, clarity and a dynamic presentation, including for classical music and larger ensembles. That makes it worth considering for varied listening at home, from albums to games. The over-ear design and self-adjusting headband give it a more substantial listening format than a basic pair of in-ear headphones, while the supplied screw-on adaptor provides a 6.3mm connection option alongside the standard 3.5mm jack.

Buyers’ opinions on sound quality are mixed: some praise the sound, while others are less impressed. Feedback on build quality is mixed too, so the stated features may be easier to judge than the product’s long-term feel. Some buyers also describe the sound as good value for its price point, but that is a reported impression rather than a guarantee of performance for every listener.

Practical tips

Choose the connection that matches the equipment you plan to use: the headphones have a 3.5mm jack, and a screw-on 3.5-to-6.3mm adaptor is included. The listed 32 Ohms impedance and 98 dB sensitivity give useful context when comparing them with other wired headphones, but the supplied details do not specify a microphone, wireless connection or noise-cancelling function.

For a home listening session, they could be used for an album or game through a compatible 3.5mm socket, the adaptor is there for equipment with a 6.3mm socket. If you mainly want a simple wired listening option, that flexibility may be more relevant than features aimed at calls or blocking outside sound. Keep the choice grounded in the connection and listening features actually listed.

Who it’s for

Worth considering if you want over-ear headphones for music, games or home-studio use, and value the option of both 3.5mm and 6.3mm connections. The stated response range may also appeal if you listen to varied material, including classical or large-ensemble recordings. The self-adjusting headband and earpads are practical comfort details, although no measurements or wear-test information are provided.

You may want to skip it if noise control is a priority: none is listed. Likewise, the supplied information does not identify a microphone or wireless use, so this is not presented as a feature-rich communications headset. Compared with a more basic wired pair, its stated driver size and frequency range offer more to weigh up for music listening, a buyer seeking noise control or call features should look for those explicitly instead.

Should you buy it?

The HD681 makes most sense when you want a wired, over-ear pair for varied home listening and can use its 3.5mm jack or included 6.3mm adaptor. Its wide stated frequency range, 50mm neodymium drivers and self-adjusting fit give it a clear use case beyond casual background listening. The main reservation in the available information is the mixed buyer feedback on sound and build quality, so it is harder to treat those as assured strengths. Choose it for the listed listening format and connection options, not for unlisted noise control or headset functions.
