The Nirve Portable MP3 Speaker is a cost effective way for cycling around town with tunes safely.
At 207 X 98 X 78mm, the light portable MP3 speaker minimizes occupancy anywhere it’s mounted. It runs off of 4 AAA batteries for approximately 7 hours of continuous play time. The quality of sound is fair for its price. Sound is projected at its users rather than being lost to its environment.
The mountable speaker connects through a standard 3.5mm headphone jack, making computability no issue. To adjust the volume, however, access can be difficult due to no external controls.
At $24.99, we say it’s a buy.
