The Little Dot Micro+ builds upon the success of the original Little Dot Micro portable headphone amplifier by using a new more powerful amplification chip, higher quality components, and a rechargeable integrated lithium-ion battery so you never have to hassle with batteries again! The Little Dot Micro+ includes an AC charger which accepts 110-220V to recharge or to act as a power supply for home use.

The sound quality of the Little Dot Micro+ can best be described as "wire-with-gain," neither adding nor detracting from the original source signal for maximum audio fidelity. If you are serious about transparency and audio quality in a portable or even a home setting, the Little Dot Micro+ is for you.
