Sennheiser HD25 Review

The Sennheiser HD25 is one of three new headphones – along with the HD25 Plus and the HD25 Light – that borrows design cues from the orignal Sennheiser HD25-1ii. But are these new headphones a clear upgrade, or marketing smoke and mirrors?

The HD25s feature the same design as the older HD25-1ii, with an expanding headband, on ear design, and a left earcup that can rotate 90 degrees for one-ear listening.  The whole thing is primarily comprised of plastic, but also features a modicum of pleather padding.

The headphone can be easily un-assembled and easily re-assembled. This allows a user to replace any part of the headphone with minimal effort, obviously extending the life and potential use of the headphone.

In general, the HD25 gives an impression of quality and comfort, resting weightlessly on my head and casually reassuring me with it’s rugged build quality.

Included in the box is a 1/4” adapter that screws onto the end of the 1.5 m (5 ft) cable.

The Sennheiser HD25s feature a frequency range of 16-22000 hertz, and a nominal impedance of 70 ohms.

Detail remains startlingly good, with excellent separation and a complete lack of distortion. No part of the frequency range gets any undue, over-the-top emphasis.  Instead, the whole sound can be described as contrasty yet flat. As such, these headphones are a perfect option for DJs or most audio professionals, as well as some discerning audiophiles.

Is there anyone who won’t benefit from these headphones?  If you’re looking for massive amounts of bass, other headphones will probably suit your tastes better.  Likewise, if you’re looking for something stylish and flashy to flaunt in front of your friends, these headphones may not be the optimal candidate.  But if you’re searching for a refreshingly articulate sound, then look no further.
