Title says it all really. It’s a Bluetooth retro handset by Native Union. I usually find things like this a ridiculous price for a bit of retro fun and indeed the RRP is £24.99 but at £1.99 it’s a bit alright. I've only had a quick test of it and it seems okay, mixed reviews online everything from poor battery life to bad microphone pickup. I decided £1.99 was worth a punt, can't comment on battery life but in the very limited testing the microphone seems okay.
The original retro handset designed for Native Union by David Turpin with Bluetooth® technology. Inspired by the 1950s Bakelite phone, timeless style in collectable fun colours (ONLY BLACK IN WIGAN). The POP Bluetooth® allows you to navigate your device while you talk and reduces background noise for clearer conversation. It feels great, sounds great, and looks great. The Bluetooth® technology offers great mobility wherever you may be.
They had a few other Native Union bases and handsets also for £1.99. I'm sorry I didn't pay much attention to these as they were corded not Bluetooth.
