- 35mm driver, 3W / 4Ω output — practical sound output for personal listening in small spaces

Designed for portable personal listening
The YSW33 is built for users who want a compact Bluetooth speaker they can carry clipped to a bag or in a pocket — the aluminium alloy body provides rigidity without significant weight, and the built-in lanyard means it does not need a separate case or holder. TWS mode connects two YSW33 units wirelessly to operate as a stereo left/right speaker pair, which is useful for outdoor listening where a single small speaker may feel spatially narrow. At 2–3 hours playback the YSW33 is suited to short sessions; a 1–2 hour charge via USB restores the battery. Curated by Aetheo for practical personal audio.
Key features
Aluminium alloy + silicone body
The YSW33 housing uses aluminium alloy for the main body and silicone for accent/grip surfaces. Aluminium provides rigidity and a premium feel at a low weight for a 3W speaker unit. The silicone surfaces add grip and protect the speaker during carry.
35mm driver, 3W / 4Ω
The 35mm driver delivers 3W of output power at 4Ω impedance — appropriate for personal listening in quiet environments or small rooms. The driver size and output power suit the compact form factor of the YSW33.
Jieli 6632 Bluetooth 5.0, TWS
The Jieli 6632 chip provides Bluetooth 5.0 connectivity. TWS (True Wireless Stereo) mode pairs two YSW33 speakers together to create a stereo pair — one acting as left channel, the other as right. Both speakers connect to the source device as a single pair.
300mAh battery, 2–3hr playback, 1–2hr charge
The 300mAh battery provides up to 2–3 hours of continuous playback at typical volume. Charging via 5V/1A input takes approximately 1–2 hours from empty. Actual playback time varies with volume level and audio content.
Built-in lanyard
A lanyard is integrated into the YSW33 body, allowing the speaker to be worn around the wrist or attached to a bag strap, carabiner or similar. An additional lanyard is also included in the box as a spare or accessory.

- Users who want a pocket-sized Bluetooth speaker for outdoor or travel use
