If you want a complete wired listening setup with an inline mic built into the earbuds themselves, choose C G CHANGEEK 3.5mm; if you need a replacement cable that restores the inline mic and volume controls on a pair of Bose QuietComfort QC25 or QC35 headphones you already own, choose EARLA TEC Replacement Audio Cable.
• C G CHANGEEK 3.5mm — biggest strength: a full in-ear headphone with dual 10mm dynamic drivers, ear hooks, three sizes of ear tips, and an inline button for volume, play/pause and track skipping. It's a complete product, not a part.
• C G CHANGEEK 3.5mm — biggest trade-off: it's built around a 3.5mm jack and balanced sound rather than heavy bass, the inline controls may not work on every PC or MP3 player, and devices without a 3.5mm output need an adapter.
• EARLA TEC Replacement Audio Cable — biggest strength: it's a direct replacement cord for Bose QC25/QC35 (plus SoundLink and SoundTrue) headphones, with a 3.5mm-to-2.5mm male-to-male design, an inline mic and volume remote, and a 1.5 m TPU cable with one straight and one L-shaped plug.
• EARLA TEC Replacement Audio Cable — biggest trade-off: it only makes sense if you already own compatible Bose headphones — it's a cord, not a listening device, and it won't add sound to anything on its own.
• Who each pick is for: C G CHANGEEK for someone who wants a ready-to-use wired headset for sport, running, gaming or calls on a 3.5mm device; EARLA TEC for a Bose QC25/QC35 owner whose original cable has worn out and who wants the mic and remote back.
The C G CHANGEEK 3.5mm is a complete in-ear headphone, and the spec sheet reads like it was designed for movement. Two 10mm NdFeB dynamic drivers cover a 20Hz–20kHz range with 32 ohm impedance and 100 dB sensitivity — numbers that suggest it's easy to drive from a phone or laptop without extra amplification. The ear-hook design wraps around the ear, which is exactly the kind of thing you want when you're running, lifting or gaming and don't want a bud popping loose mid-set. You also get three sizes of ear tips, so you can pick the fit that seals best and blocks ambient noise for better concentration.
So who should buy it? In my opinion, this is for the person who wants one wired product that handles listening, calls and sport in a single purchase — someone with a 3.5mm jack on their phone, tablet, laptop or handheld who doesn't want to think about cables and parts. Who should skip it? Anyone who wants deep, bass-forward sound (this is tuned for balanced bass, alto and treble, not boom), anyone on a device without a 3.5mm output who doesn't want to carry an adapter, and anyone who already owns a premium over-ear pair and just needs a cord — that's a different job entirely.
EARLA TEC Replacement Audio Cable: Who It's For
The EARLA TEC Replacement Audio Cable is a very different kind of product, and it's important to be clear about that: it is a cable, not a headphone. Its whole purpose is to replace the cord on Bose QuietComfort QC25, QC35, SoundLink and SoundTrue headphones. It's a male-to-male cable with one straight plug and one L-shaped plug, running about 1.5 m (150 cm), made from soft, durable TPU, in blue. The two plug sizes — 3.5mm and 2.5mm — are what let it slot into the Bose headphone side and your source device at the same time.
What makes it more than a dumb wire is the inline mic and remote. The control pod gives you hands-free calls and music operation: answering and hanging up calls, adjusting volume high/low, and skipping to the previous or next track on iPhone and iPod. The sheet also lists compatibility with older iPhone models (3GS through 6 Plus), Samsung and some Android phones, plus laptops, PCs, smartphones and several Amazon Fire tablet generations.
Who should buy it? If you own a Bose QC25 or QC35 and your original cable has frayed, gone missing or lost its mic function, this is the straightforward fix — you keep the headphones you already like and restore the inline mic and controls without replacing the whole thing. Who should skip it? Anyone who doesn't own compatible Bose headphones. Without that specific pair, this cable has nothing to connect to, and it won't serve as a general-purpose headset. It's also the wrong pick if you want a cable for earbuds or a non-Bose over-ear model.
• Best for a complete listening setup out of the box → C G CHANGEEK 3.5mm. It includes the drivers, tips, ear hooks and mic — nothing else to buy.
• Best for restoring an existing Bose QC25/QC35 → EARLA TEC Replacement Audio Cable. It's purpose-built for those models and brings back the inline mic and volume remote.
• Best for sport and running → C G CHANGEEK 3.5mm. The over-ear hooks and three tip sizes are designed to stay put and seal out noise during movement.
• Best for hands-free calls on a 3.5mm phone → both can do it, but C G CHANGEEK 3.5mm is the all-in-one option, while EARLA TEC only works if your headset is a compatible Bose model.
• Best for long-reach listening → EARLA TEC Replacement Audio Cable. Its ~1.5 m length gives more slack than a typical earbud cord.
• Best if you're on a device without a 3.5mm jack → EARLA TEC Replacement Audio Cable, since it's a cable you'd pair with your own headphones and source; C G CHANGEEK would need a Lightning or USB-C adapter.
• Best for bass-heavy listeners → neither is the obvious pick. C G CHANGEEK is explicitly tuned for balanced sound rather than heavy bass, and EARLA TEC is just a cable.
• Best for durability-minded buyers → EARLA TEC Replacement Audio Cable on paper, thanks to its TPU jacket, though C G CHANGEEK also notes a 12-month replacement warranty and 100% pre-ship inspection.
If I had to pick one, I'd buy the C G CHANGEEK 3.5mm — but only because of who it's for. It's the product that actually does something on its own: sound, fit, mic, controls, all in one. In my opinion it's the smarter buy for most people who just want wired earbuds with an inline mic for calls, gaming and running. The EARLA TEC Replacement Audio Cable is the right answer for a narrower, very specific buyer: the Bose QC25/QC35 owner who needs a replacement cord with a working mic. If that's you, buy it without hesitation. If it isn't, C G CHANGEEK is the one I'd recommend. Either way, check the current price on Amazon before you commit.
what is an inline mic on headphones
An inline mic is a small microphone built into the headphone cable rather than into the earcup. Both products here have one: on the C G CHANGEEK 3.5mm it sits in the control pod alongside the volume and play/pause buttons, and on the EARLA TEC Replacement Audio Cable it's part of the inline remote that also handles calls and track skipping.
how to use wired headphones with mic on pc
Plug the 3.5mm connector into your computer's audio jack. The catch is that PCs with separate headphone and microphone jacks need an audio mic splitter for the microphone to work — that's noted for the C G CHANGEEK 3.5mm. Also expect that inline volume and control buttons may not function on a PC or laptop, since support depends on the application.
C G CHANGEEK 3.5mm is listed as compatible with iOS and Android, provided your device has a 3.5mm jack — Lightning-only iPhones need an adapter. EARLA TEC Replacement Audio Cable lists older iPhone models (3GS through 6 Plus), Samsung and some Android phones, and it's primarily intended for Bose QC25/QC35 headphones.
The C G CHANGEEK 3.5mm. Its over-ear hooks and three sizes of ear tips are designed to hold the buds in place and block ambient noise, which suits running, sport and gaming. The EARLA TEC Replacement Audio Cable is a cord for over-ear Bose headphones, so it isn't built for that use case.
