Echo Wall Bluetooth Speaker with Card Reader and Metal Shell 550x50x50mm

This wall-mounted Bluetooth speaker is designed for listeners who want audio without taking up shelf or floor space. It combines Bluetooth 4.0 wireless streaming with a 3.5mm audio jack, a built-in card reader, radio, voice prompt, and call function. The metal shell and box give it a solid feel, and the black finish suits a range of indoor settings. With 5W x 4 output power, a signal-to-noise ratio of at least 75dB, two speakers, and two channels, it is built for general listening. The built-in lithium battery provides up to 8 hours of playing time, and the 15-metre effective distance lets you move around while staying connected. Button operation keeps things simple, and there is no display to distract from the clean front profile.

Features and Construction

The core features centre on flexible playback and a metal-bodied build. The speaker supports Bluetooth 4.0 and a 3.5mm audio jack, so you can choose wireless or wired connection. A card reader handles expansion storage up to 32GB, and MP3 and WMA files are supported. The radio function and voice prompt add useful everyday options, while the call function means you can take calls through the speaker. The shell and box are both metal, and the appearance size is 550 x 50 x 50mm. Two size options are listed: 330 x 50mm and 550 x 50mm.

Material and Build

The shell and box are made from metal, which gives the speaker a rigid enclosure suited to wall placement. This is not a claim about waterproofing or extreme durability; it simply reflects the stated material. The metal surface can be wiped with a soft dry cloth to keep it clean. The black colour is the only colour option given. Two speakers are fitted, and the unit operates through buttons rather than a touchscreen or display. No display is included, so all control is via the buttons.

Size and Practical Fit

The appearance size is 550 x 50 x 50mm, and the available size options are 330 x 50mm and 550 x 50mm. These dimensions refer to the unit itself as stated by the manufacturer. The slim profile is intended for wall mounting, but no mounting hardware or installation method is specified in the source text. Please check the listing for fitting details. The 15-metre effective distance gives some freedom when using a paired device, and the 8-hour playing time supports longer sessions between charges.

Uses and Placement

This speaker is aimed at general users and can suit both event-style background audio and everyday home listening. Because it is wall-mounted, it can be placed without using a table or shelf. The card reader and radio functions are useful when you want to play from a memory card or listen to radio without a phone. The call function and voice prompt add convenience for hands-free communication. No specific venue, room size, or professional certification is claimed.

Event or Professional Use

For shops, studios, or similar indoor spaces, the wall-mounted design keeps the floor clear and places sound at ear level. The 5W x 4 output power and two-channel stereo setup are intended for general listening rather than large-scale PA use. The metal shell and box provide a solid housing, and the black finish blends into most interiors. Bluetooth 4.0 and the 3.5mm jack allow quick connection to common devices. The radio and card reader functions can be useful when a simple standalone audio source is preferred.

Everyday Home Use

At home, the speaker can be wall-mounted in a kitchen, living area, or bedroom to play music from a phone, memory card, or radio. The 8-hour playing time from the built-in lithium battery means it can run for a good part of the day without recharging. The 15-metre effective distance lets you keep your phone nearby or move around. Button operation is straightforward, and the voice prompt gives audible feedback. No display is fitted, so settings are managed through the buttons alone.

Benefits and Buying Value

The main buying value comes from combining several playback options in one wall-mounted unit. Bluetooth, 3.5mm jack, card reader, radio, and call function are all stated features, so you are not relying on a single source. The metal shell and box are easy to wipe clean, and the built-in battery avoids the need for a permanent power connection during use. The slim 550 x 50 x 50mm profile and the alternative 330 x 50mm size give some choice depending on available wall space.

Reuse and Low Maintenance

The built-in lithium battery can be recharged and used again, and the 8-hour playing time is stated by the manufacturer. The metal shell can be cleaned with a soft dry cloth, which is a low-risk approach for a metal surface. No other maintenance instructions are provided, so avoid using harsh chemicals or excess water. The card reader supports memory cards up to 32GB, so existing MP3 or WMA files can be reused rather than replaced. No lifespan or battery cycle claims are made beyond the stated playing time.
