Features and Functionality

Equipped with the latest Bluetooth 5.3, the GRESTU YYK-Q730 Wireless Headphones have fast and stable wireless connectivity.

Sound Quality

With 10mm drivers in each earbud, the GRESTU YYK-Q730 Wireless Headphones deliver very pleasing sound with sparkling highs and solid mids. The bass has decent punch but lacks the sub-bass depth of some in-ear models. Overall, the open-air sound stage is spacious with very good clarity for podcasts, audiobooks, and music across various genres. Volume levels go high enough for noisy environments.

Microphone Quality

The built-in mics on the GRESTU YYK-Q730 Wireless Headphones pick up your voice clearly in quiet settings. However, background noise reduction is just average so call quality suffers in noisier rooms or outdoors. For voice calls, performance is best in quiet indoor settings.

Noise Isolation

Since these are open-ear headphones, they intentionally allow ambient noise in so you remain aware of your surroundings. No active noise cancellation is present. The earhooks provide a gentle seal to block out some noise passively, but these are designed for situational awareness rather than noise isolation.

Battery Life

Battery life is a major highlight, with up to 6 hours continuous playback on the earbuds and an additional 30 hours from the charging case. This gives a total massive battery life of 36 hours between charges. Quick charging offers 1 hour of playtime from just 10 minutes charging.


The Bluetooth 5.3 wireless connection offers reliable pairing and link stability within the 10m wireless range. Some users faced occasional signal drops but connectivity is solid overall for most. Auto-pairing makes it fast and easy to connect.


On each earbud, the touch-sensitive surface enables control over music playback and calls. Double tap to play/pause, triple tap to skip tracks, long press to adjust volume, and tap to answer/end calls. The controls are conveniently located and easy to use.
