Wireless Waterproof Portable Bluetooth Subwoofer with 8-Hour Playtime and Multiple Audio Inputs

This portable Bluetooth speaker is designed for users who need reliable, versatile audio in various environments. Its compact, waterproof build houses a 5W audio system capable of delivering boosted sound for up to 8 hours on a single charge. The unit distinguishes itself with multiple playback sources: Jerry Bluetooth 5.0 for wireless streaming, a TF card slot for offline MP3 libraries, a standard 3.5mm auxiliary input, and built-in FM radio. A practical carrying belt is included, making it easy to transport the 81mm x 81mm x 116mm device to gardens, picnics, or while travelling. The addition of hands-free calling functionality means it can serve as a speakerphone, adding to its utility beyond music playback.

Features and Construction

The speaker's core functionality is built around its audio components and connectivity options, all housed within a waterproof casing for durability.

Material and Build

The speaker features a waterproof exterior, protecting the internal electronics from moisture during outdoor use. Inside, the sound is produced by an external magnetic speaker rated at 4Ω 5W and an external magnetic horn with the same specification, described as having a 52-side, 45-tape design with secondary magnetic 16 cores and an empty tape booster. This construction is intended to provide the noted 'sound with boost'. The unit is controlled via physical buttons for mode selection, volume adjustment, and call management.

Size and Practical Fit

The device has a compact, square-ish profile with bare metal dimensions of 81mm in width, 81mm in depth, and 116mm in height. This size makes it suitable for placing on tabletops, shelves, or carrying in a bag. The inclusion of a portable belt allows the speaker to be hung or carried easily, enhancing its mobile use case. It is available in five distinct colour finishes: black, blue, camouflage, grey, and red, allowing for personal preference or matching with other gear.

Uses and Placement

Its combination of portability, durability, and multiple audio sources makes it adaptable for different scenarios, from casual listening to more active outdoor situations.

Event or Professional Use

For small events, markets, or mobile professional use, the speaker's 5W output and boost function can provide background music or public address support. The FM radio function is useful for live broadcasts or specific programming, while the hands-free calling is practical for taking business calls without needing to hold a phone. The speaker can also be paired in a '1+1' series with another unit to potentially widen the sound coverage for a slightly larger area.

Everyday Home Use

Around the home, it serves as a versatile audio hub. You can stream music via Bluetooth from a phone or tablet, play a curated playlist from a TF card without needing a connected device, or listen to local FM radio stations. Its waterproof nature means it can be used safely in kitchens or bathrooms where condensation or splashes might occur. The 8-hour battery life supports extended use without constant recharging, suitable for all-day listening.

Benefits and Buying Value

The value of this speaker lies in its practical integration of several common audio features into a single, rugged, and portable unit, reducing the need for multiple devices.

Reuse and Low Maintenance

The speaker is designed for repeated daily use. The 1500mAh lithium battery features a double protection board for safety and longevity across charge cycles. The waterproof casing helps protect against accidental spills and light rain, potentially extending the product's usable life in varied environments. With no complex care requirements beyond keeping the ports dry when charging, it offers a low-maintenance audio solution.

Why Choose This Product

This product is a practical choice for someone seeking a single audio device that consolidates several common functions: wireless Bluetooth streaming, offline digital playback, FM radio, and auxiliary input. The confirmed 8-hour playtime, physical portability via its belt, and hands-free calling add layers of utility not always found together in compact speakers. The choice between five colours allows for personalisation. It provides a straightforward, feature-rich audio tool without relying on a single source or connection type.
