How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to restore the wired connection on a pair of Beats or Sony over-ear headphones you already own, choose Callez Beats Headphones Replacement; if you need a low-profile wired earbud you can fall asleep in without charging anything, choose GREKING Sleep Headphones USB-C.
• Callez Beats Headphones Replacement — biggest strength: a 5.02 ft / 153 cm male-to-male 3.5 mm aux cable with 24K gold-plated plugs and oxygen-free copper wiring, aimed squarely at Beats Solo/Studio and Sony WH-series owners who want their headphone back.
• Callez Beats Headphones Replacement — biggest trade-off: it is a cable, not a headphone. No mic, no volume control, and it explicitly does not fit Bose or JBL.
• GREKING Sleep Headphones USB-C — biggest strength: ultra-low-profile silicone earpieces with retention loops, built for side sleepers, plus an inline mic and 3-button remote over USB-C.
• GREKING Sleep Headphones USB-C — biggest trade-off: it's wired to a USB-C port, so it only works with devices that output audio over USB-C — no 3.5 mm jack, no Lightning.
• Who each pick is for: Callez if you already own compatible Beats/Sony headphones and the stock cable died. GREKING if you want a dedicated sleep/travel earbud and your phone or tablet has USB-C.
This is a repair part, and it's honest about that. The Callez cable is a straight 3.5 mm to 3.5 mm aux cord measuring 5.02 ft / 153 cm, built with polished 24K gold-plated plugs and oxygen-free copper conductors, wrapped in TPE that the spec sheet describes as resistant to twisting, pulling and tangling. The connectors are the whole point: they're sized and shaped for the recessed jacks on specific Beats and Sony models, which is where generic aux cables often fail — they fit the hole but not the housing.
Compatibility is where you need to read carefully. Callez lists Beats Solo2, Solo3, Studio2, Studio 2.0, Studio 3, Studio 3.0, Studio 3 Wireless, Studio Wireless, HD Pro, Mixr and Detox, plus Sony WH-1000XM5, XM4, XM3, XM2, WH-CH720N, WH-CH710N, WH-CH700N, WH-XB910N and more. It also plays nicely with Skullcandy, Audio-Technica, Soundcore/Anker, AKG and Philips sets that use a standard 3.5 mm port. On the source end it handles phones, laptops, desktops, tablets, the PS4/PS5/Xbox/Switch controllers — with two caveats: newer iPhones need Apple's Lightning-to-3.5 mm adapter, and Xbox needs the original headset adapter.
GREKING Sleep Headphones USB-C: Who It's For
The GREKING S800 is a different animal entirely — a wired in-ear sleep bud rather than a replacement cord. The design brief is comfort in bed: soft silicone earpieces kept deliberately low-profile so they don't dig into your ear when you lie on your side, with integrated retention loops that hold them in place through the night. If you've ever woken up with a hard plastic earbud jammed into your ear canal, that silhouette is exactly what this product exists to avoid.
The audio tuning follows the same logic. GREKING describes it as smooth and non-fatiguing — the kind of sound you can leave running under a white-noise app, an audiobook, or a podcast for hours without listener fatigue. The driver is a 6 mm dynamic unit with 32 ohm impedance, 102 dB sensitivity and a 20,000 Hz frequency response ceiling, which tells you it's built to be easy to drive from a phone or laptop rather than to deliver thumping bass. Noise control is sound isolation, not active cancellation — the silicone seal does the blocking.
The inline module is a real convenience for a sleep product: a microphone and a 3-button remote let you change volume, control playback, take calls and trigger your voice assistant without hunting for your phone in the dark. The housing is metal, the weight is 40 g, and there's no battery and no charging — it draws power from the source, which is the entire appeal for overnight use. USB-C is the only connection, and GREKING names iPhone 15/16/17 and Samsung S25/S24/S23 series among the compatible devices, alongside tablets, laptops and desktops.
Buy it if you're a side sleeper, a traveller on overnight flights, or someone who wants a corded sleep bud that never needs a charge and never dies at 3 a.m. Skip it if your phone or player has only a 3.5 mm jack or Lightning — this is USB-C audio or nothing — and skip it if you want deep bass or active noise cancellation for commuting.
Side-by-Side: Which Should You Choose?
• You want something to sleep in → GREKING Sleep Headphones USB-C, since the low-profile silicone earpieces and retention loops exist for exactly that.
• Best for side sleepers → GREKING. The Callez cable doesn't care how you sleep; it's a cord.
• Best for audio quality with existing premium headphones → Callez, in the sense that it lets you keep using the headphones you already like, provided the connection is intact.
• Best for calls and on-the-fly control → GREKING, which has a built-in mic and 3-button remote. The Callez cable has neither, by design.
• Best for USB-C-only devices → GREKING. Callez needs a 3.5 mm port or the right adapter.
• Best for Bose or JBL owners → neither, strictly speaking — Callez doesn't support those brands, and GREKING is an earbud, not a cable.
• Best for a no-charging, no-battery setup → both qualify. Neither has a battery; both are pure wired connections.
• Best low-risk purchase if you're unsure → check compatibility first. Callez publishes a long supported-model list and offers a compatibility guide; GREKING's requirement is simply "does my device output audio over USB-C?"
These two barely compete — they solve unrelated problems, so the honest answer is that you buy the one that matches your situation rather than the one that's "better."
In my opinion, if you're the typical shopper searching this comparison because a Beats or Sony cable gave out, the Callez Beats Headphones Replacement is the pick: it's cheap insurance on headphones you already like, and the gold-plated OFC construction and two-year warranty make it a sensible long-term fix. I'd choose the GREKING Sleep Headphones USB-C only if sleep, side-lying comfort and USB-C are genuinely your priorities — in that case its silicone low-profile design and inline controls are the reason to buy, and nothing else on this page will do the job.
FAQ
Only if your iPhone has USB-C. GREKING specifies USB-C audio devices including iPhone 15/16/17 and Samsung S25/S24/S23 series. Older iPhones with Lightning, or anything with a 3.5 mm jack, won't work without the right adapter — and even then, only if the adapter supports USB-C audio.
No. Callez states plainly that this audio cable has no built-in microphone and no volume control. If you need to take calls or change volume from the cable, the GREKING Sleep Headphones USB-C has both an inline mic and a 3-button remote.
They're not comparable purchases — one is a replacement part, the other is a set of earbuds. Judge each on what it replaces or adds: Callez restores headphones you already own, GREKING gives you a sleep-specific earbud you don't have. Check the current price on Amazon for both and decide based on which job you actually need done.
