JBL OnBeat Xtreme review

We've been following the onslaught of AirPlay / Bluetooth speaker systems in recent months, carefully combing through the prospects to find the true contenders. We were recently impressed by Klipsch's Gallery G-17 Air and now we've given the JBL OnBeat Xtreme a testdrive. This beast is step up from the regular ol' OnBeat dock, both in stature and cost. Priced a cool $500... it's sandwiched between the pricey B&W Zeppelin Air and the more modest iHome iW1. So is the JBL dock extreme enough to warrant a purchase? We've been blasting beats through this bad boy for a fortnight, so read on to find out if you should snatch one up for yourself.
