The Good Great sound quality.

The Bad Awful build quality; uncomfortable; far too expensive.

The Bottom Line The Sennheiser HD 25-1-II Adidas Originals are heinous in every respect besides sound quality. A £200 set of headphones shouldn't feel so cheap and uncomfortable.

4.5 Overall

As geeks go, we're a sporty bunch, taking the stairs instead of the lift at least once or twice a year. That means we're well qualified to assess the Sennheiser HD 25-1-II Adidas Originals headphones

We expected the Adidas branding to inflate the price, and it does -- the non-branded version of these cans costs about £40 less. But, for £200, we still expected a slick pair of headphones. Unfortunately, they're absolutely horrible in every respect besides sound quality.

Originals sin

Build quality is an extremely important factor with all gadgets. You don't want to splash out on something that's going to fall apart, cause you discomfort, or just hang about the place looking cheap. Alas, these headphones tick all of those hateful boxes.

Indeed, the build quality of these headphones is among the worst we've ever encountered. Rough and sharp plastic edges abound, and they even look plasticky and naff. We passed them around the office and asked our colleagues to guess the price. The general consensus was that they'd cost no more than £80, but that they felt like they should cost about £20. 

We were actually astonished by how poorly made they are. A key feature is that one earcup rotates upwards by 45 degrees, so you can listen to music with just one King Lear when you're getting your DJ on. We were unable to flip the earcup up with just one hand, though, because the hinge attaching it to the headband was so stiff. We ended up tugging the other earcup away from our lughole in the process. We're no mix masters, but we'd guess that's not ideal.

The hinge of the rotating earcup is too stiff to enable one-handed twisting, rendering this feature pointless.

The ratchet mechanism for adjusting the headphones to fit your noggin also feels incredibly cheap, making an unpleasant, plasticky clicking sound when fiddled with.

The headband itself can be split down the middle into two segments, which could have been a welcome aesthetic bonus. But the two parts don't separate with the smooth, comfortable action we'd expect for £200. Also, some cabling sits in a shallow inset channel on the inside of one part of the headband. Splitting the headband is liable to cause this cable to spring loose from its bed. Then, when you close the headband again, you'll find its two parts cutting into the cable. At an early stage in our testing, we noticed that the cable was becoming damaged. It's all very shonky.
