The ZDA74 is an over-ear Bluetooth headset with active noise cancelling, dual 40mm drivers and a foldable frame. It is built for everyday commuting and travel: ANC targets traffic, plane cabin and crowd noise, and the earcups use protein padding on an adjustable headband. Battery life is rated at up to 20 hours, and an audio cable lets you keep listening when the charge runs out. It competes on basics rather than premium features, with no app, no codec detail and no transparency mode mentioned.

These foldable wireless Bluetooth headphones use active noise cancelling to reduce low-frequency noise such as city traffic, plane cabins and crowds. They have dual 40mm drivers and a CSR Bluetooth chip for balanced midbass and bright treble with deep bass. A built-in CVC 6.0 microphone handles hands-free calls.
The around-ear cushions are made of protein leather, and the headband is adjustable. The design is lightweight for all-day wear. The headband material passed a 10,000+ bending test, and the clamping force has been improved for comfort. The headphones suit most head sizes.
The built-in rechargeable battery gives up to 20 hours of music (about 300 songs) or calls. When the battery is low, you can use the included audio cable instead. The headphones stream from smartphones, tablets and other Bluetooth devices within 33 ft. A separate transmitter is needed to connect to a TV.
