There’s a saying among true audiophiles. Goes like this:
Show me a man with an impressive MP3 collection, and I’ll show you a man who travels with a wildly mediocre speaker.
REX is a wireless, water-resistant, clip-on wunderkind of a speaker, designed to attach to the outside of your clothing (i.e., away from the safely zippered-up smartphone in your pocket) while cycling, snowboarding, camping or avoiding panhandlers.
You can also manage the Bluetooth controls – from volume to Siri – without ever touching your phone.
So when the call comes from across the park, you can oblige by turning the sound up without reaching for your handset.
What you play – that's all you.
