The JBL Micro Wireless is among the most highly rated speakers
in the category of ultra-portable speakers, which are typically
palm-sized and so tiny that you can easily slip them in a pocket or
purse (or even clip to your clothing).
The sound is surprisingly full
for such a small device, especially the bass. It’s compatible with
any Bluetooth device and uses a USB cable for recharging the
lithium-ion battery. It also has jacks for non-Bluetooth devices.
