What's the best feature? For the Sport Pulse, the multi-function button and volume control that sits on the wire connecting the headpieces is inspired. It basically does everything. For the Elite Sport, the charging case included in the box doubles as a handy carry case and also contains two full charges, perfect for travelling. Both sets come with a whopping three-year warranty against sweat. That's a solid promise for a set of headphones getting bashed about while you exercise.
And what's the worst? Charging the Sport Pulse is a pain: you'll need to shift aside the rubber band around an earpiece, then force it in. My review set never felt like it fit properly. And the tradeoff for the lack of a wire on the Elite Sport comes, as expected, with sound. It's lacking a little punch, especially when it comes to bass. If that's a big deal for you, go for the Sport Pulse edition.
Okay, so how much are they? The Sport Pulse retail for $319, while the Elite Sport go for $399. I'd happily recommend both, but if you're sick of those pesky wires, go with the Elite Sport model. Wires are so 2010.
