Portable Bluetooth speaker with 20-hour playtime

The No Sew S15-1-YTUS-BK is a compact portable speaker designed for listeners who want wireless audio indoors or outdoors. It connects via Bluetooth 5.4 to smartphones and other compatible devices. The unit includes a built-in microphone for hands-free calls and a real-time battery level display that shows remaining charge down to one percent.

Sustained output with dual drivers and DSP

Dual 60 mm full-range drivers and DSP digital audio processing deliver room-filling stereo sound that covers areas up to 90 m². The 4000 mAh lithium battery provides up to 20 hours of playtime at 30 percent volume with lights off, or 24 hours under similar conditions. A full charge takes roughly three hours, supporting extended sessions without frequent recharging.

Upgrades from basic mono speakers without TWS

This model replaces single-driver units that lack true stereo separation and bass enhancement. The TWS pairing function lets two speakers create a wider soundstage for parties or movies, while Bass 3.0 technology adds deeper low frequencies with reduced distortion. Buyers who need multi-room audio systems or smart-assistant integration will not find those features here.

Questions about this item

How loud does the speaker run after hours of continuous play at 30 % volume with the lights off?

At 30 % volume and lights off the 4000 mAh battery delivers up to 20 hours of playtime, so the speaker is designed for long sessions without overheating or excessive fan noise.

What do I need to supply myself before the speaker will play audio?

A Bluetooth 5.4 source such as a smartphone is required; the package includes only a power cable for charging.

Can I pair two of these speakers together for stereo while keeping my older mono speaker in the same setup?

The unit supports TWS pairing so two identical speakers create true stereo separation; it does not bridge to non-TWS models.
