Review on Blue M30 Bluetooth Headphones Sports, Wireless Earbuds with Deep Bass, Ergonomic Design, Mono & Twin Mode, 25 Hours Battery, IPX8 Waterproof, Built-in Microphones, Type-C Charging for Workout Running by James Baker

I have several headphones like Samsung Galaxy Buds and Buds Plus, MPOW MX1 and some others. At first glance, the M30 looks like a Bud or Buds Plus, and in person it fits better than the Buds or Buds Plus. The charging port is USB 3.0, and when you put the earbuds into the case, it flashes and connects the charging cable to the case. A red LED flashes. Once all earbuds and the case are fully charged, it will glow solid blue. Second, it matched my Note 20 very well. Just turn on Bluetooth on my phone, it shows up as "MPOW MX1". The voice guard said it was connected, as well as a list of bluetooth devices in the phone. Third, I listen to music through YouTube Music and it has a balanced timbre and base. I didn't touch the sound settings or use the equalizers. Fourth, I like how to change the volume or reset the settings. Press and hold the right ear button for a few seconds to increase volume and the left ear button to decrease volume. Touching either side of the headphone button will play the previous or next track in the playlist. The box and manual say it can play for 5 hours and up to 20 hours with a charging case. I hope the next version will have more battery capacity to play 8 hours on a single charge.
