Not to toot our own horn here, but it is safe to say that HeadRoom is the world leader in headphone amplification and personal audio products. Founded by Tyll Hertsens in 1992, headphone amplifiers were a rare breed. So rare, in fact, that he found himself building his own as a DIY project to power his awesome Sennheiser headphones while on the road. (You can learn more about HeadRoom's history here.)
Fast forward 20 years and we have the HeadRoom of today: proprietor of our renowned Crossfeed circuit; inventor of the first portable USB-powered headphone amp; inventor of Balanced Headphone Drive, and easily the largest specialty headphone amplification company in the world. HeadRoom also manufactures Digital-to-Analog converters, power supplies, cables, and various accessories, and we continue to operate one of the largest headphone-specialty sites on the web, www.headphone.com. That's where you are now, so congratulations! You've already found the best place to Get It Right Between Your Ears!
