The Promate Delta-X is a true wireless speaker with 20W of stereo output driven by dual bass and treble drivers. Splitting the low and high frequencies across dedicated drivers keeps rhythm and melody distinct instead of blurring them together as volume rises. It is built to carry a room indoors and still hold together outdoors.

Two Delta-X units pair to each other over True Wireless Technology (TWS), widening the stereo image into a surround sound field instead of firing everything from one point in the room. Pairing is fast and the link stays stable once established, with no cable between the speakers. One unit works alone, and two cover a larger space.

The Delta-X carries three EQ settings, letting you move between sound profiles that run from thumping bass to pristine trebles. Electronic and hip-hop tracks get the low-end weight they were mixed for, while acoustic and vocal material stays clean at the top. You pick the profile that suits the genre instead of living with one fixed sound.

The Delta-X uses a futuristic, spaceship-inspired shape with sleek aerodynamic lines, so it reads as an object in the room rather than a plain black box. A speaker sits in plain view at most gatherings, and this one is styled to be the focal point when it does. The look is matched to the audio hardware inside it.

Twelve RGB lighting modes run on the Delta-X and synchronise with the track that is playing, making the speaker a visual element of the space as well as the sound source. Twelve options give enough range for a full-intensity party setting or something restrained for background listening. The mode is selectable at any point.

Audio-sensitive landing lights on the Delta-X illuminate in step with the sound as it plays. Rather than running a fixed pattern, they respond to the music itself, so the visual show follows what you are actually listening to. It is the detail that carries the spaceship theme through from the styling into how the speaker behaves.

An advanced omnidirectional microphone is built into the Delta-X, capturing sound from all angles instead of only from directly in front. That suits hands-free calls, gaming sessions and group conversations where people are spread around a table or a room. Playback and voice run through the same unit, so no separate microphone is needed.

A 6400mAh battery supports up to 20 hours of playback with the RGB lighting switched on, and up to 30 hours with the lighting off. That is an all-night gathering on a single charge, or several days of ordinary listening. Switching the lights off is the lever to pull when you need the longer figure.

The Delta-X supports USB flash drives up to 256GB, so an entire music library can travel with the speaker and play back without a phone or laptop attached. Load the drive, plug it in and the speaker handles the rest on its own. That covers trips with no signal, no data or no spare device to tie up.
