The Acefast H7 uses an over-ear fit and weighs 167 g, making it a reasonably lightweight option in its form factor. It features a closed-back design with stereo speakers and carries an IP54 rating, providing resistance to sweat during physical activity. The headphone does not include a detachable or tangle-free cable, and it is not designed for children.
The Acefast H7 is equipped with a 30 mm driver unit and covers a frequency range of 20 Hz to 20,000 Hz. It supports both active noise cancellation (ANC) and passive noise reduction, giving it two layers of ambient sound blocking. Spatial audio is not supported.
The Acefast H7 houses a 500 mAh rechargeable battery that delivers up to 55 hours of playback, or 45 hours when active noise cancellation is in use. It charges fully in 1.5 hours via USB Type-C and includes a battery level indicator to keep track of remaining charge. Wireless charging is not supported, and the battery is not removable.
The Acefast H7 connects wirelessly via Bluetooth 5.4 with a maximum range of 10 m. It does not support any advanced audio codecs such as aptX, aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, AAC, LDAC, or LDHC. Fast pairing and NFC-based pairing are also absent.
The Acefast H7 includes a noise-canceling microphone and can function as a headset, making it suitable for calls alongside music listening. An ambient sound mode lets users stay aware of their surroundings when needed, and controls are handled through an on-device panel rather than an in-line remote. In/on-ear detection and a dedicated mute function are not available.
