Aiwa RS-X100 Bluetooth Speaker (Black)

Aiwa RS-X100 Bluetooth Speaker (Black)

The Aiwa RS-X100 in black is a portable Bluetooth speaker from Aiwa’s Natsukasii retro range, pairing vintage-inspired styling with a current specification: 40W of output from a triple-driver system with DSP, up to 9 hours of playback from its 4000mAh battery, Bluetooth 5.0, a built-in microphone for calls, TWS stereo pairing and Type-C charging. The black finish gives the retro cabinet a sharper, more modern edge that suits offices, media units and contemporary interiors. At 252 x 160 x 142 mm it is a room speaker first — built to fill living spaces with sound rather than to slip into a jacket pocket.

Sound for real rooms

Three drivers share the frequency range so no single driver is stretched thin: low frequencies get their own output, and voices and instruments stay clear in the middle where most music lives. DSP processing manages the balance, holding the sound together at higher volumes and keeping dialogue intelligible at low ones. The specified response of 120Hz to 20kHz reflects a tuning aimed at warmth and presence, so film soundtracks, dance music, spoken word and everyday radio all sit comfortably in its range. Set on a sideboard or shelf, the RS-X100 fills a living room or bedroom without effort, and outdoors on a terrace it has the output to carry a gathering.

Battery and charging

The internal 4000mAh Li-ion battery plays for up to 9 hours between charges, so a charged speaker in the morning is still playing in the evening. Recharging runs over Type-C at 5V/2A and takes about 6 hours, a straightforward overnight routine. Because the connector is Type-C, the same cable family that charges modern phones and laptops tops the speaker up, which makes it an easy travel companion for weekends away.

Everyday versatility

A built-in microphone turns the RS-X100 into a speakerphone for hands-free calls. TWS dual-link lets you pair a second unit for genuine left-right stereo and a wider, more spacious presentation for films and music. Source options go beyond the phone: AUX connects a television, computer or media player; USB and TF card slots play music files directly from storage, handy for shops, cafes and homes that want music running without a phone tied to the speaker all day.

Choose the black RS-X100 if you want the Natsukasii combination — retro form, 40W triple-driver sound and all-day battery — in the finish that disappears into a modern setup.
