Dual Chamber Mechanism An acoustic precision designed 2 air chambers system greatly amplifies bass. With clear medium and high frequency reproduction, the overall expression is deep and rich. 2 Earbuds Positions The earbuds can be adjusted in 2 positions to give you a personalised fit to achieve greater sound isolation and a better acoustic room in your ear. Reducing sound leakage enhances the bass performance. Elastomer cord The cord is wrapped in elastomer, a highly elastic material that is tough for everyday use. L shape plug The cord ends in an L shape plug that gives a very strong and reliable plugged-in connection, especially to your portables. Portables plugged with straight shape plugs are prone to accidental unplugging. As you accidentally tug on the cord, a straight shape plug gives little resistance to the tug force. When you are using a portable on the go, you will be moving your head and body a lot. You are also likely to put your portable in your bag where it may move around, and other things in your bag will knock it around. Plenty of opportunities for accidental tuggings. An L shape plug easily deflects the tug force giving you a reliable connection always. Epi-Leather Pouch Square shape with a magnet button makes storing very easy.
