Aiwa MI-X150 Retro Plus Bluetooth Speaker

Aiwa MI-X150 Retro Plus Bluetooth Speaker

The Aiwa MI-X150 Retro Plus X is a portable Bluetooth speaker from Aiwa’s Luxury Acoustics range, pairing retro suitcase styling with modern output: 80 watts of power (2 x 40 W) from high-efficiency Class H and AB amplifiers. Aiwa’s Dual-Link technology is on board to tighten the connection between the amplifier and drivers, and a custom audio limiter keeps the sound clean when the volume is pushed to maximum.

The built-in 6,000 mAh lithium-ion battery runs for 13 to 14 hours at half volume (5 to 6 hours at full volume), and recharges over USB Type-C. Playback sources are flexible: Bluetooth 5.0 for streaming, plus USB drive, TF (microSD) card and AUX inputs for offline music. TWS support lets two MI-X150 speakers link as a stereo pair, and the built-in microphone handles hands-free calls.

• USB Type-C charging (5 V / 2 A)
• Built-in microphone for hands-free calls
• Retro-styled portable cabinet, 3.55 kg

Retro Looks, Current Engineering

The Retro Plus X is styled like a vintage travel speaker, but the internals are current: efficient Class H and AB amplifier stages rather than a single basic chip amp, a lithium-ion battery pack with Type-C charging instead of a proprietary barrel plug, and Bluetooth 5.0 with A2DP and AVRCP profiles for stable streaming and remote control from the phone. The limiter circuit is worth noting for party use: instead of distorting harshly at full volume, the speaker trims peaks, so the last part of the dial stays listenable.

Where It Works

At 300 x 180 x 180 mm and 3.55 kg, the MI-X150 moves easily between rooms, terraces and picnic spots. The 13 to 14 hour mid-volume battery life covers a full day of background music, and TWS pairing makes it a practical step up for wider spaces: place two units apart for genuine stereo separation at gatherings.

Pairing, Calls and Charging

Two MI-X150 speakers can be linked with TWS (True Wireless Stereo), so one unit handles the left channel and the other the right, giving real stereo separation across a room or terrace instead of two speakers playing the same mono signal. The built-in microphone turns the speaker into a hands-free calling device when a phone is connected over Bluetooth, useful on a desk or in a kitchen where picking up the handset is inconvenient. Charging is over USB Type-C at 5 V / 2 A, and a full charge takes approximately 8 to 9 hours, so an overnight charge restores the full 13 to 14 hours of mid-volume playback. Offline sources remain available throughout: a USB drive or TF card keeps music playing even where phones and networks are out of reach.
