Review on Enhance Your Sleep and Active Lifestyle with POSNIUD Sleep Headphones Sports Headband by Joshua Martinez

This is the most comfortable sleep headset I've tried, and the design is top-notch: the control module is firm, the micro-USB charging port is lightweight accessible and the speakers you can place them in a wide range, so they are just above your ears. You can use it as a headband or as a sleep mask. The sound quality is surprisingly good, especially considering the price. and it's still an amazing feat in recording technology. It sounded as good as any other headset I've tried. I don't know the frequency response of this headset, but it reproduces high frequencies so well that I suspect it reproduces harmonics up to at least 10kHz and possibly higher. While the bass doesn't rock the floor, it's very respectable. In less than 1 week I ordered a second one so I always have a charged backup in case my battery suddenly dies; It has really good battery life, but like all BT headsets, you can't tell how much charge is left. Excellent purchase. Highly recommended.
