QCY Crossky C30S Hi-Res Open-Ear Headphones

QCY Crossky C30S Hi-Res Open-Ear Headphones

An open-ear clip that leaves your ear canal completely free, with LDAC and Hi-Res certification behind it. Compare it across our earbuds and TWS.

What open-ear actually means for you

Nothing goes into your ear canal. The driver sits just outside it, clipped over the ear, so sound reaches you through open air. The consequences are worth understanding before buying, because they are real in both directions. You hear everything around you — traffic, conversation, an announcement — which makes this the safest option for running on a road and the most comfortable for a long working day, with none of the plugged-up pressure sealed tips create. Against that, you get less bass, because a seal is what lets low frequencies build pressure, and no isolation at all on a noisy bus. Open-ear is a genuinely different product rather than a worse earbud.

Leakage, and the titanium frame

The obvious worry with open-ear is whether people around you can hear your music. QCY's answer is Directional Audio 3.0, which it says reduces leakage by 99.5 per cent — that is a manufacturer figure we have not independently measured, but directional designs do work by aiming sound at your ear rather than radiating it. The frame is nickel-titanium alloy, a shape-memory material that flexes and returns rather than deforming, at under five grams per earbud.

Audio and battery

LDAC carries roughly three times the data of standard Bluetooth audio at 96kHz and 24-bit, needing a recent Android phone; iPhones fall back to AAC. Bluetooth 6.0 handles the link. Six hours per charge and forty in total, with ten minutes giving an hour back.
