MX 3708 8-Inch Portable Trolley Speaker with Wireless Microphone

MX 3708 8-Inch Portable Trolley Speaker with Wireless Microphone

The MX 3708 Trolley Speaker is a compact portable PA speaker built around an 8-inch woofer, made for people who need clear, loud sound away from a fixed setup. It runs on its built-in rechargeable battery, rolls on wheels with a telescoping handle, and plays music over Bluetooth, USB, a TF memory card, FM radio or a wired AUX input, so it works at small gatherings, in classrooms, at coaching sessions and at outdoor functions where a mains socket is not always nearby.

Unlike a plain Bluetooth speaker, the MX 3708 Trolley Speaker is a complete small public-address unit. A wireless microphone is included, there are inputs for a wired microphone and a guitar, and the front panel gives separate treble and bass control, so announcements stay intelligible and music can be shaped to the room. The remote control covers everyday playback from a distance, and the intelligent charging circuit looks after the battery while the unit charges.

Why Choose MX 3708 8-Inch Portable Trolley Speaker with Wireless Microphone?

For its size, the MX 3708 Trolley Speaker covers the whole job: source, amplification, speaker and microphone in one rolling box. That matters when the venue changes during the day, because the same unit can move from a classroom talk to an evening get-together without re-cabling a rack of separates.

The 8-inch format is also a practical middle ground. It is large enough to carry speech and music across a room or a small lawn, yet light and narrow enough to lift into a car and wheel through a doorway. Buyers who do not need a 12-inch or 15-inch cabinet get the portability without giving up microphone inputs, FM radio or USB playback.

Key Features

• 8-inch portable PA format: an 8-inch woofer in a trolley cabinet with a telescoping rear handle and wheels for easy movement between rooms and venues.
• 40W RMS output: 40 watts RMS as listed by MX MDR Electronics, a sensible level for classrooms, small halls, shops and outdoor groups of modest size.
• Wireless microphone included: a built-in professional wireless microphone system, so announcements and karaoke need no extra receiver or cable run.
• Bluetooth, USB, TF card and FM radio: four everyday sources plus an AUX input, covering phones, pen drives, memory cards and live radio in one unit.
• Microphone and guitar inputs: plug in a wired microphone or a guitar alongside the wireless mic, useful for small performances and interactive sessions.
• Treble and bass control with remote: professional treble and bass gain circuits plus a remote control, so tone and playback can be adjusted from the audience side.

Best Suited For

The MX 3708 Trolley Speaker suits teachers and trainers who address a room, small event hosts, shop and showroom owners who want background music with occasional announcements, fitness instructors, and families who want one speaker for karaoke nights, terrace parties and festival gatherings. It is a good fit wherever the audience is a room or a small outdoor group rather than a large open ground.

Setup and Connection Guide

1. Charge the unit fully before first use and keep it on charge when it is not in use, so the battery is ready for the next outing.
2. To play from a phone, switch the speaker to Bluetooth, pair the phone, and start playback; the speaker remembers the usual pairing routine for the next session.
3. For pen-drive or card playback, copy supported MP3 files to a USB drive or TF card, insert it, and select the USB or card source with the panel or remote.
4. To make an announcement, switch on the included wireless microphone and raise its level gradually until speech is clear without feedback; keep the microphone pointed away from the speaker grille.
5. Connect a wired microphone or guitar to the mic or guitar input when a second voice or an instrument is needed, and use the treble and bass knobs to balance speech against music.

Frequently Asked Questions

What can I play music from?

Bluetooth from a phone, a USB pen drive, a TF memory card, FM radio and a wired AUX input from a DVD player, PC or other sound source. The built-in MP3 system also supports encoding, so the unit is a player as well as a speaker.

Is a microphone really included?

Yes, the MX 3708 Trolley Speaker comes with a wireless microphone system as part of the package shown in the product images, along with a remote control and a power cord, so it is ready for announcements and karaoke out of the box.
