How do they play with other devices?
As you’d expect, these speakers all include a 3.5mm audio socket for connecting to your Mac and – with one exception – they include Bluetooth so you can stream music from your iPhone or iPad.
Audioengine is the odd man out here, as its A2+ speakers lack Bluetooth (although they offer an optional wireless adapter instead). The A2+ also includes a connector for a subwoofer, as well as USB audio input, which some people may prefer over the 3.5mm line-in.
However, the winner in terms of its range of features is Roth’s OLi POWA-5. Tucked around the back of the left-hand speaker you’ll find an additional RCA stereo connector, two digital inputs for use with a TV or set-top box, and a connector for an optional sub-woofer. It even includes two USB ports that you can use to charge your iPhone (but not an iPad, unfortunately). The only thing missing is a headphone socket – which, ironically, Creative manages to include with its much cheaper T30 Wireless, clearly with an eye on the gaming market.
