QCY’s Crossky C70 is a reported China-market launch of clip-on earbuds, listed on JD.com for CNY 399. The headline’s 50-hour battery figure is not supported by the detailed launch report: IT Home gives a rating of up to 30 hours. The reason for the discrepancy is not explained.
What QCY is reported to offer
IT Home’s October 3, 2026 report describes the Crossky C70 as an open-ear, clip-on model listed on JD.com in China for CNY 399. It is reported to come in bright silver and midnight black. The following specifications and design details are attributed to that report; they have not been independently verified.

- A 0.5 mm titanium C-bridge and Aero-Pad 3.0 soft pads.
- A bud-shaped sound outlet, with a design that can be worn on either ear without assigning a left or right earbud.
- A reported SQ5 dual-driver arrangement pairing a 10.8 mm carbon-fiber dynamic driver with an 8 mm piezoelectric ceramic driver.
- Hi-Res and LDAC certification claims.
The design suggests a different fit and listening approach from sealed in-ear earbuds, but the launch report does not establish comfort, stability, sound quality, or how well the C70 performs in everyday use.
How long does the Crossky C70 battery last?
IT Home reports up to 30 hours of playback, with a 46 mAh battery in each earbud and a 500 mAh charging case. This is the detailed figure in the report, not 50 hours. The source does not explain why the supplied headline states 50 hours, so that higher figure should be treated as unresolved rather than an established specification. “Up to” is a maximum rating; the report provides no battery-test conditions or independent runtime results.

What is claimed about calls and sound leakage?
The launch report describes a six-microphone call system that combines two microphones with a VPU bone-vibration pickup. IT Home says the system senses jaw vibration to distinguish the wearer’s voice from surrounding sound and lists an average -54 dB ENC noise-reduction depth, alongside HD Voice enhancement. No measurement protocol is given, so -54 dB is a reported product claim, not a verified test result.
IT Home also reports SoundLock 3.0 leakage reduction and a privacy mode. It does not provide independent leakage measurements, so the report does not establish how much sound escapes or how effective those features are in practice.

Where is the QCY Crossky C70 available?
The reported listing is on JD.com in China at CNY 399. QCY’s official international clip-on collection lists the Crossky C50, C30, and C30S, but not the C70; the retrieved new-release collection does not show it either. Those pages do not confirm C70 availability outside China, but their omission is not proof that the earbuds are unavailable worldwide.

Anyone comparing clip-on earbuds should weigh fit and stability, awareness of surroundings, codec support, call pickup, battery claims, leakage control, price, and availability in their own market; the launch report alone cannot establish how the C70 compares in actual use.
