YouTube channel LobbaMobba have posted this review of the Nokia MD-51W JBL PlayUp Portable Wireless Speaker.
The rechargeable portable speaker connects to the Nokia Lumia 920 with Bluetooth using NFC, and unlike the JBL Powerup wireless speaker does not provide wireless charging.
It is however much cheaper at around Â£144 vs Â£279 and still delivers excellent performance.
See two further videos, with a sound and signal strength test and build quality review after the break.
