## Questions & Answers

**Q: What is the difference between Sennheiser CX 300 II and Betron RK300 ?**
A: I don't know the Betron, but I own both the SoundMAGIC ES20 and E10 and they are better built than the Sennheiser.  SoundMAGIC cabling is really well made and the earphones themselves are constructed from aluminium.  The Sennheiser's feel a bit cheap and plasticy to me.

**Q: Do they come in the manufacture case as it would if I were to buy it from a store?**
A: Yes it comes in a plastic casing which is very hard to get into lol

**Q: How do you adjust the length of the wire for each individual headphone once they split off?.. The left headphone is far shorter than the right one**
A: Hey Sam, sadly you can't. The idea is that the longer wire goes behind your neck. It stops the headphones getting in the way. Hope this helps.

**Q: Do they leak noise? Being in ear I am hoping they wont. Please help!**
A: Well, if your playing your iPod on full volume without them in your ears, you'd be able to hear the music. But when worn, the sound of anything around you is about half as loud, maybe less. This means you don't have to push the volume much in order to hear NOTHING but your music, at 50% vol you can't hear anything going on around you unless in a "louder-than-usual" environment, I think at 60% ish you get more of a crisp! full sound! anything above that really isn't needed unless your hard of hearing. I've noticed more in the music I've listened to before with these phones so I'd say they keep the sound in your ear when worn, this is possibly supported more so by the fact that half as much sound gets in from the outside.I'm sure anyone who isn't an audiophile who wants best of the best would be satisfied with these earphones, they are better than anything similar for the same price, in my opinion.
