How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to bring a dead pair of Beats or Sony headphones back to life for wired listening, choose Callez Beats Headphones Replacement; if you need a fully wireless, sweat-proof set of earbuds for workouts and calls, choose sajawass Earbuds.
• Callez Beats Headphones Replacement — biggest strength: a 3.5mm to 3.5mm aux cable with 24K gold-plated plugs and oxygen-free copper wiring, built specifically for Beats Solo2/Solo3/Studio2/Studio3 and several Sony WH models.
• Callez Beats Headphones Replacement — biggest trade-off: no microphone and no volume control, and it will not work with Bose or JBL headphones.
• sajawass Earbuds — biggest strength: true wireless Bluetooth 5.3 earbuds with a 13mm driver, IPX7-rated water resistance, and up to 75 hours of total playtime with the charging case.
• sajawass Earbuds — biggest trade-off: they are in-ear buds, not over-ear headphones, and they need to be charged rather than simply plugged in.
• Choose Callez if you already own compatible Beats or Sony headphones and just need a reliable replacement wire.
• Choose sajawass if you want cord-free listening for sports, commuting, and phone calls.
This is a single-purpose product, and that's the point. The Callez cable is a 5.02 ft (153cm) male-to-male 3.5mm aux cord designed to slot into specific headphones: Beats Solo2, Solo3, Studio2, Studio3, Studio 2.0/3.0, HD Pro, Mixr and Detox, plus a long list of Sony models including the WH-1000XM5, WH-1000XM4, WH-1000XM3, WH-CH720N and WH-XB910N. If your headphone's stock cable has frayed, gone missing, or developed a loose connection, this is the kind of part that quietly solves the whole problem for a fraction of what new headphones cost.
The build is where it earns its keep. The plugs are 24K gold-plated to resist corrosion, and the conductors are oxygen-free copper wrapped in TPE. In plain terms: gold plating helps keep the contact points clean over time, and OFC wire is chosen because it carries a clean signal without adding noise. Callez also advertises short-circuit protection and a tangle-free, lightweight design at just 18 grams. It's a straight cable, so it hangs naturally and coils up small in a bag pocket.
Who should buy it: anyone with a compatible Beats or Sony headphone who wants wired listening again — on a plane, at a desk, plugged into a laptop, PS5/Xbox controller, or a phone with a 3.5mm jack. Who should skip it: anyone expecting a microphone or inline volume buttons, since this cable has neither. Also skip it if you own Bose or JBL headphones — Callez explicitly states it is not compatible with those brands. And note the fine print: newer iPhones need Apple's own Lightning-to-3.5mm adapter, and Xbox controllers need the original headset adapter. If you're unsure about your model, Callez offers a compatibility guide and backs the cable with a 45-day replacement window and a 2-year warranty.
The sajawass Earbuds are the opposite kind of purchase: a complete wireless listening system. They run Bluetooth 5.3 with a range of up to 10 meters, which the brand says delivers faster transmission and a more stable connection with minimal latency. For everyday use — phone in a pocket, walking around the house, moving between rooms — that stability matters more than any spec sheet number, because dropouts are the thing that ruins wireless earbuds.
Sound and calls are handled by a 13mm dynamic driver paired with ENC (environmental noise cancellation) on the microphone. A 13mm driver is on the larger side for earbuds, which is why sajawass claims powerful bass alongside a mellow midrange and clear treble. ENC is worth understanding: it doesn't silence the world around you like active noise cancellation on over-ear headphones — instead it focuses on separating your voice from background noise so callers hear you clearly. If you take calls while walking or working out, that's the feature doing the heavy lifting.
Battery life is the headline. You get over 8 hours from a single charge and a total of 75 hours with the charging case, topped up via Type-C in about 1.5 hours. An LED digital display shows remaining battery for both the buds and the case, so you're not guessing. The design is built for movement: TPE ear hooks, three tip sizes for a proper seal, and IPX7-rated water resistance for sweat and rain. Touch controls handle play/pause, calls, volume, track skipping, and voice assistant activation.
Who should buy them: runners, gym-goers, commuters, and anyone who wants wireless freedom and long battery in a rose gold finish. Who should skip them: listeners who prefer over-ear headphones, and anyone who wants a wired connection — these have no jack at all.

In my opinion, these two products shouldn't really be compared head-to-head, because they solve different problems. If your Beats Solo3 or Sony WH-1000XM4 still sound great and only the cable has failed, I'd buy the Callez Beats Headphones Replacement — it's a targeted fix with gold-plated plugs, OFC wiring, and a 2-year warranty, and it keeps a headphone you already love out of the drawer. But if you're starting fresh and want wireless earbuds for running, gym sessions, and calls, I'd choose the sajawass Earbuds for the Bluetooth 5.3 connection, IPX7 protection, and 75-hour total playtime. Match the product to your actual need, not the other way around.
Yes. Callez lists the Studio 3, Studio 3.0, Studio 3 Wireless, Studio 2, Solo2, Solo3, HD Pro, Mixr and Detox among compatible Beats models, plus several Sony WH-series headphones.
They use ENC noise reduction on the microphone, which helps separate your voice from background sound during calls. That's different from active noise cancellation, which blocks ambient sound for the listener.
No. Callez states the cable has no built-in microphone and no volume control, so it's for audio playback only.
