Cuffie Havit H668BT

The Havit H668BT headphones in violet combine wired and wireless connectivity to provide flexible listening for music, calls and media. Lightweight at 204 grams with a head-band wearing style, they offer active noise cancellation (ANC) down to -25 dB, long battery life, and support for AAC and SBC codecs. The foldable design and soft ear cups make them easy to wear and carry, while dual-device Bluetooth pairing allows seamless switching between two connected sources.

Advantages

Active noise cancellation reduces ambient sound by up to -25 dB, helping to create a quieter listening environment for travel, work or relaxation. Battery life extends up to 80 hours at 60% volume without ANC and up to 50 hours with ANC engaged, and a USB-C fast charge restores full power in approximately 1.5 hours. Audio is driven by 40 mm drivers with a frequency response up to 40 kHz and a sensitivity of 111 dB, and Hi-Res certification plus AAC/SBC support ensure clear, balanced playback. The headphones are lightweight, foldable and feature an adjustable headband for comfortable long-term use.

How to use

Charge the headphones using the supplied USB-C cable until the battery is full. For wireless use, enable Bluetooth on your source device and follow pairing prompts to connect; the H668BT can maintain two simultaneous Bluetooth connections and will switch to incoming calls automatically. Use the integrated controls on the ear cup to adjust volume, skip tracks, answer calls and toggle ANC. For wired use, connect an audio cable to the headphone jack on the source device and the headphone input. Adjust the headband and ear cups for a comfortable fit before prolonged listening.

Recommendations

To balance battery life and noise reduction, enable ANC when ambient noise is high and disable it when you need the longest possible playback. Keep firmware and source device Bluetooth profiles up to date for best compatibility with AAC/SBC codecs. Store the folded headphones in a protective case or pouch when not in use to prevent damage to the headband and ear cups.
