The Belkin SoundForm Surround uses an over-ear fit and features a closed-back design with stereo speakers. It can be folded for more compact storage, and the detachable, tangle-free cable measures 1.2 meters in length, offering straightforward cable management when wired use is preferred. The headphones are not designed for kids and carry no water resistance rating, making them better suited for everyday indoor environments.
The SoundForm Surround uses a 40 mm driver unit and covers a frequency range of 20 Hz to 20000 Hz. It includes passive noise reduction to help block out ambient sound, though it does not feature active noise cancellation, spatial audio support, or a neodymium magnet.
The SoundForm Surround is equipped with a built-in rechargeable battery offering up to 60 hours of battery life, charged via USB Type-C. A battery level indicator lets users keep track of remaining charge at a glance. The battery is not removable, and the headphones do not support wireless charging or solar power.
The SoundForm Surround supports both wireless and wired connectivity, with wireless operation running on Bluetooth 5.4 at a maximum range of 10 meters. It does not include advanced audio codecs such as aptX, aptX HD, aptX Adaptive, aptX Lossless, aptX Low Latency, LDAC, LDHC, or AAC, and there is no support for Bluetooth LE Audio or Auracast. Fast pairing and NFC-based pairing are also absent, meaning connections are established through the standard Bluetooth pairing process.
The SoundForm Surround can be used as a headset and includes a single microphone, though it does not offer noise cancellation on the mic or a dedicated mute function. Controls are handled via an on-device panel rather than an in-line cable remote, and there is no in/on-ear detection to automatically pause playback. Multipoint connectivity supports up to two simultaneous device connections, while features like ambient sound mode are not included. The headphones come with a 2-year warranty.
