ifrogz has added the line of its earPollution series portable speaker, namely Bomb. This personal speaker with a tennis ball size has two 50mm drivers, which I think I even saw in headphones and rated power is 2 x 2 watts, and that over a nominal impedance of 4 ohms.
The Bomb has frequency response restricted between 220Hz and 18,000Hz, which can only translate into a complete lack of bass and definitely not crisp high frequencies. Power required by the Bomb is either suited by three AAA batteries, a USB connection or a 4.5 ~ 6V power supply. The signal to noise ratio is lower than some on-ear headphones, at 89dB with a 3dB attenuation/amplification across the shallow frequency response. It is available for $39.99.
