Newest hifi with deep bass brand earphone Professional Portable for PSP/MP4/MP3/iPhone/iPod

Features 1, Best for portable devices 2, Extreme Hi-Fi 3, with retail package

Features* Package1. The retail package is interestingly large for a pair of in-ear headphones, and includes the earphones themselves, along with a pair of ear-hooks to hold the cable over your ear lobes.2. There's also a very solid carrying case that holds a cleaning tool, a cable clip and three pairs of rubber tips in various sizes.3. The case is quite huge so it wont fit in a pocket, but can easily be dumped inside your backpack or purse.4. If you get the right sized tips, you'll get a pretty good fit, which in-turn will mean that the noise isolation will be good enough to block out the outside background noises, such as traffic, or if you're on public transport. They might not be the best noise isolation you've ever heard, but as far as in-ear headphones go they're pretty good for most situations.* Details1. Like most earphones in this price range, the 1.2m cable is not removable, and there's no handsfree attachment that might be present in some other headphones like the other Purity In-Ears.2. Have a frequency response of 10 18, 000 Hz and 12 ohm impedance.3. A pretty powerful sound, with the typical MID-range and forward bass.
