Sennheiser Adidas PMX-680 Sports Headphones review


Rating: ★★★★★

Tech and sports companies have been combining their knowledge to great effect in recent years. The iPod‘s ultra-successful Nike+ app is one of the world’s most popular run-trackers, while Adidas and Sennheiser also did ok with the MiCoach fitness phone. Now for the active audiophile comes another Adidas double-act, this time with Sennheiser and a new range of sports headphones.

Comprising of four pairs each with a different style, the collection was announced in January. The centrepiece being the PMX 680 neckband, a model that immediately wowed with its sex appeal.

Straight out of the box it’s obvious that attraction doesn’t end with the aesthetics. The PMX 680s are instantly the most comfortable pair of sports buds we’ve used recently. The Adidas-endorsed model feels extraordinarily natural when wrapped around the neck. They’re also the most reassuring fit; once on, there’s no doubt that they’re staying on, and they remain completely unmoved during our sprint finish. However, over a long period of time, they can start to feel a little tight, with the elasticated neckband offering little mercy. It clings to the ears for dear life and is not adjustable either.

Sennheiser Adidas PMX-680: Sound quality

The sound quality is simply fantastic, with the high-output drivers offering rich bass and well-rounded audio clarity, which remains consistent when moving through different volumes.

They’re perfect for athletes who like music in the background as a distraction, or those who prefer being blasted to a personal best by a blazing power song. When cranked way up though, the fit is such that you’ve pretty much got a set of noise cancelling headphones wrapped around your neck, so take care if you’re negotiating any roads.

Sennheiser Adidas PMX-680: Features

The Adidas/Sennheiser partnership isn’t shy on tough tech specs either, boasting a moisture protection system, which means they’re water resistant and won’t be eroded by sweat either. The cable is DuPont Kelvar reinforced and they’ll still work in temperatures as low as -10 degrees Celsius. The option of having both short and long cables is a handy addition also.


  • Tough and durable
  • Fantastic, comfortable fit


  • Can feel a little tight after prolonged use
  • Position of cable tickles the ears


The PMX-680 are best pair of sports headphones on the market, the
perfect combination of Sennheiser’s sonic prowess and Adidas’ usability. A brilliant marriage of Sennheiser-standard sound with Adidas’ comfort and style.
