Overview
The Ultimea U2621 is a 7.1-channel surround sound system built around a soundbar core, rated for 350W of total output and wired for HDMI, Bluetooth or optical input, aimed at replacing a TV's built in speakers with a fuller front-to-back sound stage.
Ultimea markets this under the Surround Sound Systems category, and the 7.1 channel layout backs that up alongside three separate ways to connect a source. The listed dimensions of roughly 15.75 x 3.54 x 2.76 inches describe a slim soundbar unit rather than a full home theater in a box, so buyers should expect a bar plus separate channel hardware rather than one single speaker enclosure.
- 7.1 channel surround configuration
- 350W total rated power
- HDMI, Bluetooth and optical connectivity
- Black finish soundbar core
Who it's for
Fits anyone replacing thin TV speakers with wider front and rear coverage, especially if the source lineup mixes an older device needing optical with a newer one that streams over Bluetooth. Not the choice for a listener who wants a compact two channel bar instead of a full 7.1 spread.
Pros and cons
- 7.1 channel layout for wide front and rear coverage
- Three input types cover HDMI, Bluetooth and optical sources
- 350W total power for a soundbar based system
- Per-channel power is modest once split across 7.1 channels
- Listed dimensions describe the bar only, not the full speaker set
Performance notes
The 350W power rating is spread across seven channels plus a subwoofer, so per channel output is modest rather than concert level, and actual loudness will depend on room size. Having HDMI, Bluetooth and optical together means the system can take a signal from a modern TV's ARC port, stream audio wirelessly from a phone, or connect to an older device through optical, covering most common home setups without an adapter.

Frequently asked questions
What does the 7.1 channel rating on the Ultimea U2621 mean?
It means the system is designed to drive seven speaker channels plus a subwoofer, rather than a simple stereo pair, spreading sound across front, side and rear positions.
Can the U2621 connect to a TV without HDMI ARC?
Yes, the system also lists Bluetooth and optical connectivity, so it can pair wirelessly with a source or connect through an optical cable if HDMI isn't available.
How much power does the Ultimea U2621 put out?
It's rated at 350W total, spread across the 7.1 channel layout rather than concentrated in one or two speakers.
