Belkin SoundForm ActiveFit

Manufacturer: Belkin

The Belkin SoundForm ActiveFit are open-ear true wireless earbuds designed for active use, featuring an IP54 rating that provides protection against sweat and light moisture. They include wingtips for a more secure fit during movement and come with a travel bag. With true wireless connectivity and stereo speakers, the SoundForm ActiveFit delivers a cord-free listening experience suited to on-the-go use.

On the technical side, the earbuds run on Bluetooth 5.4 with a maximum range of 10 meters and support multipoint connection for up to two devices simultaneously. Battery life reaches 9 hours per charge, with the included charging case extending total playback to 27 hours; fast charging is supported via USB Type-C with a 1.5-hour full charge time. The earbuds also include a noise-canceling microphone, a mute function, and voice prompts, and they can be used as a headset with on-device controls. A 2-year warranty is included.

Who is this for?

These earbuds are a practical choice for users who lead an active lifestyle and need a pair that can handle physical activity. The IP54 sweat resistance combined with the open-ear fit and included wingtips makes them well-suited for running, gym sessions, or outdoor workouts where comfort and stability matter. The 27-hour total battery life and fast charging support also make them a good fit for people who use earbuds throughout the day and need reliable, low-maintenance power. Additionally, users who frequently switch between devices or take calls on the go will benefit from multipoint connectivity and the noise-canceling microphone.

Who is this NOT for?

Users who prioritize audio immersion or need to block out environmental noise will find these earbuds lacking, as they offer no active noise cancellation or passive noise isolation. The open-ear design inherently lets in ambient sound, which makes them a poor fit for commuting in loud environments or focused listening in busy spaces. Audiophiles or those who rely on high-fidelity wireless audio will also be disappointed, as the earbuds lack support for advanced codecs such as LDAC, AAC, or any aptX variant, limiting wireless audio quality. Users who prefer wireless charging or need NFC pairing for quick setup will similarly find the feature set insufficient.
