Our first impressions of the Adidas Sennheiser PMX 680i earphones weren’t great. For one thing, the packaging is ridiculously excessive: not very green. Visit Group test: what are the best headphones?

The product itself didn’t strike us as particularly impressive at first, either. Granted, the bold but simple colour scheme is nice enough. But the plasticky headphones and neckband seemed cheap and basic. We therefore didn’t expect much in terms of comfort, or audio quality. See also Philips ActionFit Neckband review.

But we were wrong. We took the headphones for a good run, and achieved the ideal situation: we could forget about them completely, and just concentrate on the pleasure of the music, and the agony of the exercise.

As for audio, bearing in mind the mid-level price tag, the fact that they’re in-ears rather than over-ears and the generally limited quality of the competition, we thought the sound quality was outstanding, with surprisingly forceful bass and a realistic reproduction of quieter tracks.

Despite the packaging and the plasticky build, these sports headphones are comfy and boast impressive sound quality

Buying Advice:

The PMX 680i Sports headphones are light and comfortable to wear, with a secure fit that we never doubted throughout a lengthy run. But the real surprise was the audio quality: uniformly good, but particularly proficient in the bass department. The only small issue is that the neckband could bump into your glasses.
