• EARLA TEC Replacement Audio Cable — biggest strength: it restores and upgrades an existing Bose QC25/QC35 with a 1.5 m TPU cord that carries an in-line microphone plus volume, call and track buttons.
• EARLA TEC Replacement Audio Cable — biggest trade-off: it is only a cable. Without a pair of compatible headphones it does nothing, and its button functions depend on the device you plug into.
• Botesty Sound Headphones — biggest strength: a complete 40 mm over-ear headphone with a 4.9 ft tangle-free nylon cord, a 120° curved plug and a folding design for travel.
• Botesty Sound Headphones — biggest trade-off: no volume control on the headphones themselves, no noise control, and the mic only works on devices that support it.
• Pick the EARLA TEC cable if you already own Bose QC25/QC35 (or SoundLink/SoundTrue) and just need the wire replaced or extended.
• Pick the Botesty Sound Headphones if you need a full, ready-to-use headphone out of the box for a tablet, laptop, MP3/MP4 player or a flight.
Think of this as a repair part, not a gadget. The EARLA TEC cable is a 3.5 mm to 2.5 mm cord built specifically for Bose QuietComfort QC25 and QC35 headphones, and the listing also names SoundLink and SoundTrue models. If your original Bose cable has frayed, gone missing, or you simply want a spare to keep in a bag, this is the kind of item that quietly saves a headphone you already love instead of pushing you toward a new pair. The two-male-plug layout is the clever bit: one straight plug and one "L"-shaped plug, so you can match the end to the jack and the way the cable sits against your chest or pocket. The round TPU jacket is described as soft and durable, and at roughly 150 cm it gives you a bit of slack without a coiled mess.
The in-line remote is where it earns its keep for phone users. There is a microphone for hands-free calls plus buttons for answering and hanging up, adjusting volume, and skipping tracks — the kind of control set that matters when your phone is zipped in a jacket. It is listed as compatible with a long run of Apple devices (iPhone 3GS through 6 Plus) as well as Samsung and other Android phones, so it covers the everyday phones most people still carry wired earphones for.
Who should skip it? Anyone who does not own a compatible Bose headphone. There is no headphone in the box — just the cable, one piece, model BC-01. If your phone has no headphone jack at all, this is not the product that solves that; it is a replacement cord for an existing setup. And because the remote relies on your phone's own controls, a device that does not play nicely with in-line buttons may simply give you audio and nothing more. Check the current price on Amazon before buying, since a spare cable only makes sense if it costs far less than replacing the headphones.
This is the opposite kind of purchase: a finished product you can unbox and use. The Botesty Sound Headphones are an over-ear, wired model with a 3.5 mm plug, 40 mm dynamic drivers and a frequency range of 20 Hz to 20 kHz — a standard full-range spec that tells you the design is aimed at general listening rather than specialist monitoring. The over-ear cup shape and circular earpieces are meant to sit around the ear, which the brand says enhances sound with deep bass and clear output. The housing is plastic in a black-and-red finish, and it folds up so it can go into a bag or suitcase, which is exactly the use case the listing pushes: travel, commuting, school, library and laptop work.
The cable deserves a mention because it is clearly a design priority. At 4.9 ft it is a sensible desk-and-lap length, and the nylon braided jacket is there to resist tangling — the everyday annoyance that kills cheap cords. The 120° curved plug is angled to reduce strain at the jack, which is a small but real durability decision.
Now the honest trade-offs, and the brand is upfront about them. Volume cannot be adjusted on the headphones; you change it on the connected device. There is no noise control at all, so this is not a noise-cancelling or isolating-focused pick. And the microphone only works on some devices and adapters, so if you need reliable call audio you should verify your setup first. Anything without a 3.5 mm jack — many modern phones — needs a conversion adapter, and some adapters do not pass the mic through.
Side-by-Side: Which Should You Choose?
• Best for replacing a broken Bose cable → EARLA TEC Replacement Audio Cable. It is purpose-built for QC25/QC35 and slips straight into your existing headphones.
• Best for a complete headphone out of the box → Botesty Sound Headphones. Cord, cups and plug all included; nothing else to buy except an adapter if your device needs one.
• Best for in-line controls → EARLA TEC Replacement Audio Cable. Mic plus volume, call and track buttons on the cord.
• Best for travel and packing → Botesty Sound Headphones. Foldable, lightweight, with a 4.9 ft tangle-resistant nylon cord and angled plug.
• Best for long cable runs → EARLA TEC Replacement Audio Cable. Around 1.5 m of TPU cord with one straight and one L-shaped plug.
• Best for driver specs on paper → Botesty Sound Headphones. 40 mm dynamic drivers and a stated 20 Hz–20 kHz range.
• Best if you already own good headphones → EARLA TEC Replacement Audio Cable. Repair beats replace when the cans are still fine.
• Best if you want zero setup surprises → Botesty Sound Headphones, provided you accept device-side volume and check mic support.
In my opinion, these two products barely compete — they solve different problems, and the right answer depends entirely on what you already own. If you have Bose QC25 or QC35 headphones sitting unused because the cable died, I would buy the EARLA TEC Replacement Audio Cable without hesitation; it is the cheaper-feeling, smarter move than binning a headphone you like. If you have nothing to plug in, the Botesty Sound Headphones are the sensible starting point for a wired, foldable, travel-friendly pair. My pick for the widest range of buyers is the EARLA TEC Replacement Audio Cable, because it fixes a specific, common failure and adds call and volume controls for a fraction of what a new headphone costs.
Yes. The listing states compatibility with Bose QuietComfort QC25 and QC35, plus SoundLink and SoundTrue models, using a 3.5 mm to 2.5 mm connection.
No. Volume can only be adjusted on the connected device, not on the headphones, though there is an in-line microphone on supported devices.
Only with a 3.5 mm conversion adapter, and some adapters do not support the microphone, so check before you rely on calls.
That depends on your starting point. If you already own compatible Bose headphones, the cable is the lower-cost fix; if you need a full headphone, the Botesty Sound model is the more practical buy. Check the current price on Amazon for both.
