Description

The Edifier S355DB is a 2.1 active speaker system that brings Hi-Res Audio performance to your TV setup, delivering 150W RMS of room-filling sound from a pair of satellite speakers and a wirelessly connected subwoofer.

The satellite speakers feature 1.5-inch titanium dome tweeters with neodymium magnets and 3.5-inch long-throw aluminium cone mid-bass drivers, producing crisp highs and full-bodied mids. The 8-inch wireless subwoofer uses a 5.8GHz connection for flexible placement anywhere in the room, with a low-end frequency response reaching down to 44Hz.

Connectivity is exceptionally versatile, with HDMI eARC, Optical, Coaxial, USB-C, and LINE IN inputs, plus Bluetooth 6.0 with LDAC support for wireless audio streaming at up to 990 kbps. When connected via HDMI eARC, HDMI CEC allows your TV remote to control power, volume, and mute on the S355DB directly.

  • Hi-Res Audio Certified: End-to-end 24-bit/96kHz digital signal processing with tri-amped active crossover ensures faithful, high-resolution sound reproduction from every source.
  • Wireless Subwoofer: The 8-inch long-throw subwoofer connects over 5.8GHz, so you can position it wherever bass sounds best without running cables across the room.
  • Bluetooth 6.0 with LDAC: Stream high-resolution audio wirelessly from Android 8.0 or later devices, with multipoint connection keeping two devices paired simultaneously.
  • HDMI eARC: Single-cable connection to your TV with full HDMI CEC integration lets you control the S355DB with your existing TV remote.
  • Customisable EQ via App: The EDIFIER ConneX app lets you fine-tune your own sound profiles or choose from four preset effects to suit films, music, or gaming.
  • Multiple Inputs: HDMI eARC, Optical, Coaxial, USB-C, and LINE IN give you the flexibility to connect virtually any audio or TV source.

Frequently Asked Questions

Does the Edifier S355DB need a separate amplifier?

No, the S355DB is a fully active 2.1 system with built-in amplification. It delivers 150W RMS total output across tri-amped satellite speakers and a Class D powered subwoofer, so no additional amplifier is required.

Can I control the Edifier S355DB with my TV remote?

Yes, when connected via HDMI eARC, HDMI CEC integration lets your TV remote control power, volume, and mute on the S355DB. This means you don't need to use a separate remote for day-to-day TV watching.

Does the subwoofer on the Edifier S355DB need to be wired to the satellites?

No. The S355DB's 8-inch subwoofer connects to the satellite speakers wirelessly over a 5.8GHz signal, giving you the freedom to place it wherever bass sounds best in your room without running additional cables.

What Bluetooth codecs does the Edifier S355DB support?
