What reviewers say about the LG SN4

Based on 0 · 3

Reviewers love the deep bass from the subwoofer, but are split on connectivity, which works well for some and frustrates others.

What owners say about the LG SN4

Based on 62 owners sharing their experience in online comments

24%positive10%mixed66%negative

The bass draws praise, but repeated subwoofer connection failures and thin, hard-to-hear sound make the overall experience disappointing.

What owners dislike

  • The subwoofer often drops off on its own and won't reconnect, even after resetting the bar, holding the pairing button, or contacting LG support.15
  • Owners must re-pair often, phones often can't find the Bluetooth, and nearby devices can connect to it with no setting to block them.6
  • Owners say treble is weak, with only two full-range speakers and no tweeters, so dialogue sounds muffled and lacks clarity.6
  • Owners say effects play loud while dialogue stays too quiet, so they keep turning the volume up and down to follow speech.3
  • Some owners get no sound over HDMI ARC, even after support steps, and switch to the optical connection instead.3
  • Owners say it shuts off after a film is paused for a while and needs re-pairing, or switches on and off by itself when unused.3
  • Owners say maximum volume is low, about the same as the TV, and the sound gets softer as the volume is pushed to the top.3
  • Owners say it only slightly improves on TV sound, mostly adding bass, and some find it sounds more muffled than their TV.3

Third-party reviews

What customers like about LG SN4

  • The wireless subwoofer pairs on its own.
  • Solid bass from the subwoofer.
  • Bluetooth, USB and high-resolution audio support.
  • Dialogue enhancement helps speech come through clearly.
  • The companion app and the TV remote both work with it.
  • The LED display dims automatically.

What customers don't like about LG SN4

  • The middle of the sound range is weak.
  • The USB port sits in an impractical position.
  • ARC only, with no eARC support.
  • There is no Dolby Atmos and no Wi-Fi.
  • Bluetooth can cause noticeable audio lag with the TV.

Verdict

Setup is the first thing you notice with the LG SN4, a 2.1 bar with a wireless subwoofer in the box. The wireless subwoofer pairs on its own, so there is no fiddly link to set. Bass is solid, and Bluetooth, USB and high-resolution audio all work, so it suits music as well as films. DTS Virtual:X adds some width to the sound, and dialogue enhancement helps speech come through clearly. The middle of the sound range is the weak part, and the USB port sits in an awkward place. The companion app and the TV remote both work with it, so one handset covers most jobs. Its LED display dims by itself. It suits a buyer who wants clearer TV sound and solid bass without a complicated setup.
