Mono Portable Speaker Energy Sistem Bloom 10 W

Bloom is a mono portable Bluetooth speaker with a compact, colourful design and a 10 W RMS output. It features a 5.2 cm full-range driver and reproduces audio across a frequency range of 80–18,000 Hz. The speaker supports Bluetooth wireless connection (Bluetooth 5.3, 2.402–2.480 GHz) with A2DP, AVRCP, HFP and SBC profiles, and can play MP3 and WAV files from a microSD/SD card or via audio-in. The Energy Sistem Bloom is lightweight (0.331 kg), water-resistant (IPX6) and designed for on-the-go use.

Advantages

The Bloom speaker offers stable Bluetooth 5.3 connectivity for reliable wireless playback and hands-free calls, up to 18 hours of battery life for extended use, LED lighting for ambience and party settings, and True Wireless Stereo (TWS) support to pair two units for stereo sound. Its housing is made from certified recycled plastic and the packaging uses FSC-certified materials. IPX6 protection provides resistance against splashes and light rain.

Suitable for

• Outdoor activities such as beach trips, picnics and short hikes
• Small gatherings and home parties where portable sound and LED effects are desired
• Listening to MP3/WAV files from microSD/SD cards or streaming from smartphones
• Hands-free calls and voice assistant control via a paired mobile device

When it may not be suitable

The mono 10 W output and single full-range driver are designed for portable, casual listening rather than high-fidelity or loud, room-filling sound in large venues. Although IPX6 resists splashes and rain, the speaker is not rated for full submersion.

How to use

Charge the speaker before first use and switch it on. Enable Bluetooth on your mobile device and pair it with the speaker using the Bluetooth menu; the speaker also supports MP3/WAV playback from a microSD/SD card and wired audio-in. Use the speaker controls to play, pause, skip tracks, answer calls and activate the voice assistant. To increase stereo separation, pair two Bloom speakers using the True Wireless Stereo function.

What to consider before purchase

• If you need room-filling stereo sound or very high volumes, consider a larger stereo speaker system instead of a mono 10 W unit
• IPX6 offers splash resistance but not submersion—avoid immersing the speaker in water
• Check that playback formats and memory card use (MP3/WAV, microSD/SD) meet your needs

Recommendations

For best battery life and sound clarity, keep firmware updated, avoid prolonged exposure to direct sunlight, and pair two Bloom speakers via TWS when you want wider stereo coverage.
