I bought these back at their previous low price (good ol camel cubed) and they are awesome. Phenomenal for running or at the gym, and have a lifetime sweat warranty (win). It USB charges to full in about 2ish hours and is meant to get 8 hours at full charge, I've gone both more and less than this.
Only piece of advice I'd give is that the earbuds that come with them are pretty rubbish and I didn't find them comfortable so I bought some Comply Tips. Other than that, the sound is pretty good and microphone works well. If you're a bit of an audiophile they have pretty great reviews all round so you're set there.
There's some eBay sellers that have local stock and 2day delivery for a bit more. Still great earphones, use mine all the time.
