JVC SP-SQ4BT 45mm Portable Wireless Speaker

The JVC SP-SQ4BT is a compact portable wireless speaker made for convenient music playback at home, outdoors, or on the go. It combines Bluetooth streaming with a 3.5mm AUX input, giving users a wireless or wired way to play compatible audio sources. Its built-in rechargeable battery supports extended use without requiring a wall outlet during playback.

This speaker is a practical choice for listeners who want a small, self-contained audio solution for a phone, tablet, or other compatible device. Bluetooth 5.0 provides wireless connectivity with an effective line-of-sight range of approximately 33 feet. A built-in calling function also supports basic hands-free call control when connected by Bluetooth.

Stereo sound is produced by two 45mm drivers, with maximum output rated at 5 watts per channel. The speaker uses two 4-ohm, 5-watt drivers in a compact horizontal enclosure. This configuration provides separate left and right channels from one portable unit.

For expanded playback, the SP-SQ4BT includes True Wireless Stereo (TWS) functionality. Two compatible SP-SQ4BT speakers can be paired wirelessly for a true stereo setup. This is useful when a wider left/right presentation is preferred without adding a wired connection between speakers.

The SP-SQ4BT is rated IPX7 for water resistance, allowing it to be submerged in water up to 1 meter for up to 30 minutes. Its built-in 2500mAh rechargeable battery is rated for up to 22 hours of playback at 70% volume, with a listed full-charge time of about five hours. A USB charging cable is included for routine recharging.

Design & Installation

The SP-SQ4BT uses an ABS housing with a mesh or metal grille design over its drivers. Its compact enclosure measures 1.81 inches by 2.09 inches by 6.50 inches, making it easy to place on a desk, shelf, patio table, or other stable surface. The speaker is available in black.

No vehicle installation, amplifier wiring, or external power amplifier is required. Charge the internal battery through the Micro USB charging connection, then pair a compatible Bluetooth device or connect a source through the AUX input. For TWS use, a second SP-SQ4BT speaker is required; for water exposure, keep the charging and AUX connections protected when not in use.
