How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want premium over-ear immersion with adaptive noise cancelling and a wired lossless option, choose Amazon Renewed Beats Studio Pro; if you need lightweight open-ear comfort, IPX5 sweat resistance and all-day awareness for training, choose QCY Crossky C30S.
• Amazon Renewed Beats Studio Pro — biggest strength: a full-size over-ear design with adaptive ANC, Transparency mode, Personalized Spatial Audio and lossless audio over USB-C, plus up to 40 hours of playback.
• Amazon Renewed Beats Studio Pro — biggest trade-off: it's an over-ear headphone, so it's bulkier, fully closed off from your surroundings when ANC is on, and it ships as a renewed unit rather than brand-new.
• QCY Crossky C30S — biggest strength: an open-ear clip design under 5 g per earbud with Bluetooth 6.0, LDAC Hi-Res audio, IPX5 waterproofing and a 40-hour total playtime figure with the case.
• QCY Crossky C30S — biggest trade-off: open-ear means less isolation and less bass pressure than a sealed over-ear, and its 6-hour single-charge figure is modest for long sessions.
• Choose Amazon Renewed Beats Studio Pro if you want one headphone for focused listening, calls and travel.
• Choose QCY Crossky C30S if you want something you can wear for hours while running, cycling or working out without plugging your ears.
The Beats Studio Pro is a closed, over-ear headphone built around Beats' custom acoustic platform. The spec sheet lists a dynamic driver with a 20 Hz – 20 kHz frequency range and 32 ohm impedance — a normal, easy-to-drive load for a phone or laptop. What separates it from most wireless headphones is the feature stack: two distinct listening modes (fully-adaptive Active Noise Cancelling and Transparency), Personalized Spatial Audio with dynamic head tracking, and lossless audio over USB-C alongside three built-in sound profiles. In practice that means you can go from blocking out a plane cabin to hearing the gate announcement without taking the headphones off.
Battery is the other headline. Up to 40 hours total, with a 10-minute Fast Fuel charge giving up to 4 hours of extra playback, and a full charge in about 2 hours. For voice calls, the voice-targeting mics are designed to filter background noise so your voice comes through clearly — useful if you take meetings from a noisy room. Controls run through the app, voice or on-board media controls.
Who should buy it: anyone who wants one serious headphone for music, calls and travel; iPhone and Android users who value one-touch pairing and native platform features; listeners who want the option of a wired, lossless connection over USB-C. The renewed angle also suits buyers who are comfortable with a refurbished unit backed by a 1-year warranty and would rather put their budget toward the flagship design than a lower tier of new headphone.
Who should skip it: runners and gym-goers who need to hear traffic and their surroundings, people who dislike the clamping feel and warmth of over-ear pads, and anyone who specifically wants brand-new packaging. If you need water resistance for sweat or rain, note that the data sheet lists sound isolation as the noise-control method and does not state an IP rating — so I wouldn't treat it as a workout headphone.
The Crossky C30S is the opposite philosophy. It's an open-ear true wireless earbud with an anti-Z-shaped ear clip and a nickel-titanium alloy frame that flexes to your ear shape. Each earbud weighs under 5 g, and the earpiece is an earhook that sits outside the ear canal rather than sealing it. That's the whole point: no pressure, no plugged-up feeling, and you stay aware of what's around you.
On audio, QCY lists 10.8 mm dual-magnet dynamic drivers with a carbon fiber diaphragm, Hi-Res Audio and LDAC dual certification supporting 96 kHz/24-bit lossless, a 20 Hz – 40 kHz frequency range and 40 ohm impedance. The earbuds run Bluetooth 6.0 with dual-device connection, so you can stay paired to a laptop and a phone at once. Latency is stated at 60 ms, which matters if you watch video or game. Directional Audio 3.0 and reverse soundwave cancellation are claimed to cut sound leakage by 99.5%, and an AI-powered mic plus a wind-blocking structure handle calls.
Battery is 6 hours per charge and 40 hours total with the 460 mAh case; a 10-minute USB-C top-up gives about an hour. IPX5 means it shrugs off sweat, light rain and splashes. Touch controls work on the buds themselves or through the app.
Who should buy it: runners, cyclists, gym users and commuters who want music without losing situational awareness; people whose ears ache after an hour in sealed earbuds; anyone who wants a second device paired at the same time. The open-ear fit also tends to suit glasses wearers better than a deep in-ear seal.
Who should skip it: anyone who wants strong isolation on a flight or in a noisy open office, bass-first listeners who need a sealed chamber, and people who want the fuller, head-filling presentation of an over-ear design.
Side-by-Side: Which Should You Choose?
• Best for all-day, pressure-free comfort → QCY Crossky C30S. Under 5 g per earbud with a flexible nickel-titanium clip beats a full-size headband for long wear.
• Best for workouts and weather → QCY Crossky C30S. IPX5 waterproofing is stated; the Beats sheet lists no IP rating.
• Best for maximum battery per session → Amazon Renewed Beats Studio Pro. Up to 40 hours on one charge versus 6 hours per earbud charge (40 hours only with the case).
• Best for sound quality potential → Amazon Renewed Beats Studio Pro for wired listening. Lossless over USB-C plus spatial audio with head tracking is a level of processing the C30S doesn't offer; the C30S counters with LDAC and a wider stated 20 Hz – 40 kHz range.
• Best for staying aware outdoors → QCY Crossky C30S. The open-ear design lets ambient sound in without any mode switching.
• Best for calls in wind → QCY Crossky C30S on paper. It specifically lists a wind-blocking structure and AI mic; the Beats relies on voice-targeting mics, which are strong indoors but the sheet doesn't claim wind handling.
• Best for two devices at once → QCY Crossky C30S. Dual connection is stated; the Beats sheet emphasises one-touch pairing rather than simultaneous multi-device audio.
• Best for travel and flights → Amazon Renewed Beats Studio Pro. Over-ear isolation, long battery and spatial audio make it the more natural travel companion.
If I had to pick one, I'd buy the Amazon Renewed Beats Studio Pro. In my opinion it covers more of what most people actually do with headphones — focused listening, calls, travel and the option of a wired lossless connection — and its 40-hour battery and adaptive ANC are the more versatile package. The renewed status and the lack of a stated water-resistance rating are the real costs, so if you're a runner or you need to hear traffic, I'd point you to the QCY Crossky C30S instead: it's the smarter buy for open-ear comfort, workouts and staying aware. Check the current price on Amazon before deciding, since renewed pricing moves around.
FAQ
The sheet lists Active Noise Cancellation under noise control, but remember these are open-ear buds — they don't seal your ear canal, so isolation is far lower than a closed over-ear like the Beats Studio Pro. Think of it as reduced leakage and clearer calls rather than a quiet-cabin effect.
The Beats gives up to 40 hours on a single charge. The C30S gives 6 hours per charge and 40 hours total only when you count the charging case, so for one uninterrupted session the Beats lasts much longer.
Yes — IPX5 covers sweat, light rain and splashes, and the under-5 g clip fit is built for movement. The Beats Studio Pro sheet doesn't state a water-resistance rating, so I'd keep it out of the rain and away from heavy sweat.
