Boasting dual 5W Harman Kardon speakers, we found the audio quality was decent with good volume and clarity.

Battery life we found to be around two hours when unplugged from the mains, which means average length films should be fine but the Halo+ will likely struggle with epic runtimes. The XGIMI’s LED lamp is claimed to last up to 30,000 hours, which is around ten years of use if the XGIMI were used for eight hours a day., In need of a portable projector rather than a full-sized one?
