What to know before buying

Listing details to confirm

Battery runtime is inconsistent across the listing: some passages claim up to 6 hours, while another says about 5 hours. Treat these as conditional claims rather than a guaranteed duration. The 48V phantom-power figure in one specification block conflicts with the feature note stating no phantom power, so confirm microphone requirements before purchase. The title and specifications describe a 6.5-inch speaker, while the detailed speaker configuration also lists a 2.75-inch tweeter. The listed 40W output appears across the page, but the detailed block calls it RMS. USB playback is described as MP3/WMA only, not WAV/MKV, while recording and streaming are separately described through USB-C OTG and 3.5mm jacks. The product detail list names connectors but does not enumerate every connection described in feature copy, so confirm the exact ports and their functions if a particular connection is essential.
