Great earphones, the best I've used. The base is perfect and the highnotes are well defined. When I first got these earphones I thought they were a massive rip off and was going to send them back, but after trying a few of the different earbuds, I found the one for me, and the sound and comfort level improved immediately. Make sure you find the best combination of fit and comfort for you, there are plenty of attachments that come with these 'phones. The earloops in the cable take a bit of getting used to, but once you're used to them, they're not an issue. I find them useful as I generally use the to listen to my MP3 player when exercising, and the earloops prevent the headphones from slipping/falling out. They come with a little metal tin to transport/store them, which looks great, and provides very good protection. I would give them full marks, but I only give them 4/5 for 'Ease of use' as they take a little getting used to, but it's worth the effort!
