Amazon has discounted a rather popular pair of Sennheiser wireless headphones. Bringing the price of the Sennheiser HD 4.40 wireless headphones down to just $99. It is usually priced around $149.99, so that's about 33% off of the regular retail price.
The Sennheiser HD 4.40 wireless headphones are exactly what you would expect from Sennheiser. Which means a good pair of headphones with some incredible sound quality. These are wireless, so there's no wire here with controls, like you might find on other headphones that are wired. Instead, the controls are on the earpads, which keeps them out of the way, but still easy to use when you need to. The Sennheiser HD 4.40's do also support Bluetooth 4.0 and aptX, so you will get great audio on these headphones. These also offer up around 25 hours of playback on a single charge, which is actually a bit more than the average right now for wireless headphones, they are usually right at 20 hours, so getting a cool 25 hours is definitely nice to see and nice to have.
