Aiwa RS-X150 Speaker

Aiwa RS-X150 Speaker – Retro Portable Bluetooth Speaker with 60W Output

The Aiwa RS-X 150 Natsukasii Pro is a portable Bluetooth speaker with a deliberately retro design and a serious output for its size. Aiwa India lists it as a 60 W speaker with triple drivers, Bluetooth 5.0 and up to 12 hours of playback, aimed at listeners who want the look of a classic tabletop set with modern wireless convenience. The styling gives it a presence that plain plastic portables do not have, so it works as a visible piece of the room rather than something to hide away.

Under the retro exterior, the RS-X 150 uses triple drivers with DSP technology to distribute sound evenly, a combination Aiwa positions for deep, full coverage from a single unit. Its published frequency response is 125 Hz to 16 kHz with a signal-to-noise ratio above 60 dB. Power comes from a built-in 6000 mAh lithium-ion battery, rated for up to 12 hours of playback at 50 percent volume, and charging over USB Type-C at DC 5V/2A takes about 2 hours.

Everyday listening, several ways in

Bluetooth is the default for phones and tablets, but the RS-X 150 does not depend on it. A USB drive or TF card can carry a music library directly, the AUX input covers wired sources such as a laptop or an older player, and the supported format list includes FLAC and WAV alongside MP3 and WMA, so higher-quality files are not turned away. The built-in microphone turns it into a speakerphone for calls, and the power display keeps the remaining battery visible instead of leaving you to guess.

TWS pairing and placement

With TWS dual-link technology, two RS-X 150 speakers can be linked for true stereo, giving a wider picture for a living room or a terrace gathering. On its own, the 300 x 180 x 180 mm cabinet sounds full at a desk or on a shelf, yet stays portable enough to move between rooms.

Battery and charging

The 6000 mAh battery is rated by Aiwa India for up to 12 hours at 50 percent volume, which covers a full day of background listening or an evening of music without a cable. Type-C charging is a practical choice because the same cable type charges most current phones, and a full recharge takes about 2 hours. Included accessories are the Type-C charging cable and an AUX line, along with the manual and warranty card.

The RS-X 150 Natsukasii Pro suits buyers who want a portable speaker with character: retro looks, 60 watts of output, flexible playback options and a battery that lasts the day. It is an easy speaker to live with, at home or on the move.
