Third-party reviews

What customers like about LG Music Flow H4

  • Dual-band Wi-Fi and Bluetooth connectivity offer versatile wireless options.
  • Built-in rechargeable battery enables portable use away from a wall outlet.
  • Seamlessly integrates into a multi-room audio system or works as wireless rear surround channels.
  • Solid build quality and attractive, premium physical design.
  • Supports high-resolution audio files like FLAC and WAV up to 24-bit/192kHz.
  • Google Cast support allows easy integration with popular streaming apps.

What customers don't like about LG Music Flow H4

  • Bass extension can feel subdued or lacking in deep punch.
  • Mid-range audio performance can sometimes sound hazy and congested.
  • The Music Flow companion app and wireless sync are occasionally buggy, leading to audio dropouts.
  • Limited battery life, maxing out at roughly six hours of playback.
  • Provides a limited sense of stereo separation when used as a standalone speaker.
  • The older Bluetooth version (Bluetooth 4.0) lacks modern enhancements found in newer speakers.

Verdict

The LG Music Flow H4 (NP8350) is a 20-watt, 2.0-channel portable wireless speaker measuring 194 x 64 x 70 mm and weighing 0.8 kg. It features dual-band Wi-Fi (2.4/5GHz) mesh networking, Bluetooth 4.0, Google Cast integration, dual passive radiators, a 3.5mm auxiliary port, and a built-in rechargeable lithium-ion battery. Key advantages include seamless multi-room audio pairing, crisp vocal clarity with surprisingly punchy bass for its compact size, and high-resolution audio support. However, it is held back by a relatively short battery life of only 4 to 6 hours, occasional multi-room synchronization issues, software bugs within the Music Flow app, and the lack of a built-in speakerphone microphone.
