First Look at the HMD Boom E1: 5W Output, IPX7 Rating, and Budget Appeal

HMD (Human Mobile Devices) appears poised to broaden its hardware portfolio beyond smartphones, with new leaks pointing toward the imminent release of a budget-friendly audio accessory. According to recent reports, the company is developing a compact, ruggedized Bluetooth speaker dubbed the HMD Boom E1.

The information comes courtesy of the X (formerly Twitter) tipster known as HMD_MEME’S, a source with a track record of sharing details regarding the Finnish manufacturer’s roadmap. If the leak proves accurate, the Boom E1 represents a clear effort by HMD to build out an affordable accessory ecosystem surrounding its mobile handsets.

HMD Boom E1 : Compact Design with Rugged Ambitions

Visually, the leaked render depicts a device designed for portability and outdoor utility. The speaker features a circular, puck-like chassis finished in a vibrant blue hue. The front is dominated by a tactile fabric mesh, while a prominent HMD logo sits atop the casing. Notably, the design includes an integrated lanyard loop, suggesting the device is intended to be clipped onto backpacks or carried during hikes.

Perhaps the most significant specification revealed in the leak is the device’s durability. The Boom E1 is rated IPX7, a certification that ensures the speaker is waterproof. This rating typically means a device can withstand submersion in water up to one meter deep for 30 minutes, making the Boom E1 a viable companion for poolside listening or unpredictable weather conditions.

Under the Hood: Specs and Connectivity

In terms of audio performance, the Boom E1 appears to target the entry-level segment. The leak indicates the device is powered by a 52mm driver paired with a 4-ohm horn, delivering a maximum output of 5W. While this won’t compete with larger, premium sound systems, it is a standard configuration for personal, ultra-portable speakers in this form factor.

Connectivity options strike a balance between modern standards and legacy utility. The device reportedly supports Bluetooth 5.0 for wireless streaming and retains a 3.5mm AUX line-in port—a feature increasingly rare in modern audio gear but welcomed by users who prefer wired connections. Additionally, a built-in microphone suggests the speaker can double as a speakerphone for hands-free calls.

Power is provided by an 800mAh battery charged via USB-C, ensuring compatibility with modern smartphone chargers.

Market Positioning

While pricing and specific release dates remain under wraps, the specification sheet suggests the HMD Boom E1 will compete in the budget tier, challenging established rivals like the JBL Go series or entry-level options from Anker Soundcore.

Physical controls, including playback and volume adjustments, are reportedly located on the bottom of the unit, keeping the aesthetic clean. As HMD continues to establish its brand identity independent of the Nokia legacy, accessories like the Boom E1 are a logical step in offering a cohesive user experience.
