The OBS‑53D (Rover) is a portable Bluetooth speaker with vibrant RGB lighting that cycles through millions of colors and synch to your music. It has Bluetooth 5.3 for a stable wireless connection, plus AUX input support. The speaker is hand‑held and rated IPX5 for splash resistance, making it suitable for both indoor and outdoor use. It also supports TWS (True Wireless Stereo), so you can pair two Rover 53D units for stereo sound. Its battery is 2,400 mAh, which gives about 6 hours of playtime with lights on and 7 hours with lights off. For sound, it uses two 50 mm custom drivers plus two 66 mm bass radiators tuned by Oraimo’s HavyBass™ DSP for deeper bass and richer detail.
