Have a soft spot for wireless speakers? There were tons of options out there already, but JBL just threw one more into the ring with its On Tour iBT. As we'd expect form the audio gurus, the system boasts wireless audio internals that play nice with both A2DP and AVRCP Bluetooth devices. In addition to four JBL Odyssey transducers, the kit packs a built-in microphone for Facetime or hands-free calls, an adjustable iPad stand and a USB connector for charging -- when the Katy Perry tune blastin' device is plugged in itself, of course. Interested? It can be yours now via the source link for $150, but if you'd care to take a closer look before committing, peep the gallery below.
