On Ear Smartphone Headset HD 231i

No matter where and when, you'll always be happy to have your HD 231i along for the ride. Its full sound and dynamic bass reproduction keep you going, day in and day out.

The closed, supra-aural acoustics screen out surrounding noise - the clatter of the train or the chatter of people sitting next to you - so you can immerse yourself in the excellent bass-driven Sennheiser stereo sound.

When a call comes in, take it using the smart in-line remote control with microphone. It's been especially developed for use with Apple devices, like the latest generations of iPod, iPhone and iPad*. You can control the volume, answer and end calls, use the iPhone Voice Control function and browse and play your music all from a sleek unit located directly on the cord.

The HD 231i doesn't just sound great, it's stylish and super comfortable, too. With individually adjustable ear cups featuring large, very comfortable cushioning and a soft, secure headband, the HD 231i makes your daily commute something to look forward to.

* The remote and microphone are supported by iPod nano (4th generation and later), iPod classic (120GB, 160GB), iPod touch (2nd generation and later), iPhone 3GS, iPhone 4, iPad, Macbook, Macbook Pro and Mac Pro (2009 and later). The remote is supported by iPod shuffle (3rd generation and later). Voice Control is supported by the latest iPod touch, iPhone 4 and iPhone 3GS. Audio is supported by all iPod models.
