So I bought this one 6 months ago as a replacement for another almost two hundred euros headphone, which broke immediately after I bought it because of a little contact with rain. Hoping that the FIT 500 would live up to its claim of being sweat-proof (also rainproof I hoped). And it did!

The Plantronics BackBeat Fit Boost Edition offers steady bass and ergonomics but not much else to warrant its high expense.

Flexible; sturdy design; Improved bass response; Good call quality; Portable and waterproof charging pouch

Mids and highs are weak; Inconvenient control setup; No additional ear tips; Too expensive

When it comes to fitness orientated Bluetooth headsets, there's always a bit of sacrifice to be made when it comes to sound quality. Many devices I've tested in the past suffered from this, and while you're out on the road or in the gym, you do get distracted enough not to worry about it.

Awesome sound; sweatproof design; good battery life

Clunky control box that messes with the fit

Love these headphones - these are my second pair. First pair gave me almost three years of solid use both at the gym and on many runs - the longest a pair of sports headphones has ever lasted me. Never fell out, easy to use and a good sound.

Great headphones for running and working out. Sound quality is good and controls are easy to figure out. I lost my previous headphones and immediately re-ordered the same ones.

Volume output is not loud enough to watch movies/tv. Battery life is better than previous version.

The Plantronics BackBeat Fit Boost Edition earphones comes with a cool charging case, but the in-ear fit really kills the audio experience. You might be able to hear your surroundings, but it's at the cost of bass response.

Carrying pouch features rechargeable battery; Open design allows you to hear your surroundings; Waterproof

Subpar audio performance; So-so mic intelligibility; Only ships with one pair of eartips

IP57 rated; Durability; Safety-oriented

Connection drops; Sub-par volume controls

Sound quality is impacted by putting the phone in my pant pocket. Would expect it to work normally from that close.

Continuing my long search for practical exercise-appropriate Bluetooth headphones, I'm having a look this week at the Plantronics BackBeat FIT earphones.

Good sound; comfortable fit; good wearing; reasonable Bluetooth connection

Limited bass; limited noise isolation
