QCY Crossky C30
| TWS | Open Ear | 10.8mm Dynamic Driver |
QCY Crossky C30, a brand new and unique TWS earbud from QCY.
Throughout the decade reviewing headphones, we have tested several QCY products and usually they tend to offer good quality and excellent bang for buck.
The QCY Crossky C30 join the vast catalog of headphones, earphones and earbuds from QCY as a new kind of product with a design that the brand calls C-Shape.

In fact, the QCY Crossky C30 do not fall under neither of the typical headphones categories (in-ear, on-ear, over-ear), these have an innovative new design with a clip-on system.
Each earpiece holds inside a dual magnet dynamic driver with a diameter of 10.8mm and noise-cancelling microphones for phone calls (this is not an Active Noise Cancelling headphone)
On top of that, the C30 hare compatible with the smartphone app from QCY for customizations and has an IPX4 waterproof rating to adapt better to sports activities.
The QCY Crossky C30 might be tiny but they are still able to provide up to 25 hours of runtime when combined with the OTG charging cycles of the case; the earbuds alone reach 5.5 hours per charge.

B
Bass & Sub Bass
Open-ear and bone-conduction headphones usually fall short in the bass department due to the nature of their acoustic design and lack of adequate seal conditions for the dynamic drivers.
The QCY Crossky C30 is not a bone-conduction headphone but the clip-on design and non-in-ear design makes it share the same style of acoustics of an open-ear.
Due to this, the C30 is not a bass-heavy earbud but, still, is well tuned as to offer acceptable mid-bass to give some body to your music listening sessions.
Despite this, users can expect sufficient mid-bass for most tracks and no flat nor bass-less overall sound for general purpose listening sessions.
It is important to highlight that the clip-on system of the QCY Crossky C30 can make it prone to misplacement for optimal and correct sound quality as users could fit them too high, too low, incorrectly angled and/or tilted.

M
Mids & Vocals
Despite the “open-ear style”, the QCY Crossky C30 offer a noticeably better midrange than other sports open-ear headphones.
Male vocals showed a present and never distant nor congested sound while lower mids did not suffer from mid-bass bleed.
In spite of this, the QCY Crossky C30 neither exibited lack of warmth nor a thin and flat midrange.
Upper mids and female vocals were able to provide a sufficiently crisp and alive performance without being too forward nor disturbing – in fact, this QCY earbuds were not harsh at all.

C
Comfort
You will notice that there are no buttons on the QCY Crossky C30, this is because these TWS earbuds have touch-sensitive controls on the outer part of their body; the touch system recognizes several single and multi-touch inputs to cover all main controls for music, calls and voice assistance functions.
The unusual form factor will make new users wonder how to wear this TWS earbud, as these need to be clipped-on to your ears around the mid-section of the ears.
Each earpiece is remarkably small and can adapt with ease to any ears size, thanks to a flexible C-arc with silicone finish.

In general TWS have a horrific fit for high-intensity activities and sports as they tend to fall out the ears and get lost; at first, we were afraid that the QCY Crossky C30 could suffer from the same issues but we were gladly surprised with highly secure and stable fit that did not move a single bit during several training sessions while testing them.
On the other hand, for long hours of use we did notice some fatigue over the outer ear sections where the C-arc is sitting.
