We think the sound quality is possibly the best currently available for a Bluetooth NC headphone with very well-detailed highs above clean, focused vocal midranges with a smartly controlled but full bass response that's not overly bloated or loose-sounding. In fact, the musical presentation is remarkably similar to the wired HD 1 edition and maintains nearly the same level of resolution, dynamic extension and tonal balance. That's really quite an impressive feat for wireless Bluetooth cans.
Excellent high-end leather earpads create an effective seal and a comfortable fit around the earlobes. The wide headband shape fits heads of various sizes quite comfortably and without slippage. The folding hinged stowaway design and included hard-sided storage case makes the Sennheiser HD1 Bluetooth NC a perfect mobile solution to haul in any backpack or carry-on bag.
Overall, the Sennheiser HD 1 Over Ear Wireless Bluetooth Noise Cancelling headphones are extremely impressive given all its useful design features and top-of-category sound quality performance. And you even get peace of mind from the free 2-year 'repair or replace' warranty from one of the best high-end headphone manufacturers on the planet when proof-purchased from authorized Sennheiser dealers - like us here at Headphone.com since 1995!
