If you want a drop-in replacement cable for your Bose QuietComfort 15 that keeps inline mic and remote control on a 3.5mm connection, choose Alitutumao Replacement Audio Extension; if you need a longer cable that also fits the QC25, QC35, SoundLink and SoundTrue family, plus phones, laptops and PCs, and you want the option of plugging into a 2.5mm jack for Xbox-style setups, choose EARLA TEC Replacement Audio Cable.
• Alitutumao's biggest strength: it's a straight replacement for the QC15 — gold-plated 3.5mm plug, OFC copper wire and a built-in mic with talk, volume and music control in a 140cm tangle-free cord.
• Alitutumao's biggest trade-off: it's tied to one headphone family (QC15), so if you own QC25 or QC35 it simply isn't the right fit.
• EARLA TEC's biggest strength: much wider compatibility — QC25, QC35, SoundLink and SoundTrue headphones, plus iPhone, Samsung and Android phones, and laptops/PCs, with one straight plug and one L-shaped plug and roughly 1.5m of TPU-jacketed cable.
• EARLA TEC's biggest trade-off: the 3.5mm-to-2.5mm jack arrangement and two male plugs mean you need to check which end your device actually takes before you buy.
• Buy Alitutumao if you own Bose QuietComfort 15 and want a like-for-like black replacement cord with inline mic and controls.
• Buy EARLA TEC if you own QC25/QC35 or SoundLink/SoundTrue, or you want one cable that can also serve a phone, laptop or PC — and you'd rather have the blue TPU build.
This is a single-purpose cable, and that's exactly the point. Alitutumao builds it as a replacement audio cord wire compatible with the Bose QuietComfort QC15 noise cancelling headphones. The plug is gold plated at 3.5mm, the conductor is OFC copper, and the cable is described as soft and durable with a tangle-free design. If your QC15 cable has frayed, gone intermittent, or the inline remote has stopped responding, this is the kind of part that gets the headphones working again instead of retiring them.
The inline module is the headline feature. It bundles talk control, volume control and music control into a built-in remote mic, so you can take calls and manage playback from the cable itself rather than reaching for your phone. That matters for anyone using wired headphones with an inline mic day to day — commuting, walking, working at a desk with a smartphone, tablet or music player as the source. Alitutumao lists smartphone, tablet and music player as the intended devices, and the connector runs male-to-female with three pins. The cord measures 140cm, so roughly 4.6 feet — enough slack to move your head without yanking the plug out, short enough not to snag on everything.
Who should skip it? Anyone who doesn't own QC15. If you're on QC25 or QC35, this isn't your cable — the compatibility line is explicit, and buying it hoping it'll fit is a waste of a return. I'd also steer away if you specifically need a 2.5mm end, an L-shaped plug for a tight recessed jack, or a cable long enough to stretch across a couch to a console. Those aren't features this cable claims. It's a black, round, AUX-type cord built to do one job for one headphone family, and it does that job with the connectors and materials you'd want in a replacement part.
EARLA TEC takes the opposite approach: one cable, many homes. It's a replacement audio cable cord wire compatible with Bose QuietComfort QC25 and QC35, plus SoundLink and SoundTrue headphones. That already covers a lot more Bose owners than the Alitutumao option. But the compatibility list doesn't stop at headphones — it also names Apple iPhone 3GS through 6 Plus, Samsung and "parts Android phones," and the product data lists laptops and PCs as compatible devices as well. If you want a spare cord that can move between your headphones and a computer, this is the more flexible pick.
The physical design is where it separates itself. You get two male plugs — one straight and one L-shaped — and the cable runs about 1.5 metres, which is longer than the Alitutumao cord. The jack arrangement is 3.5mm to 2.5mm, which is the detail worth reading twice: it's an adapter-style cable built to bridge two different jack sizes, so it suits gear that expects a 2.5mm connection on one end. The cable material is TPU, described as soft and durable, and it comes in blue rather than black. The inline microphone and remote buttons give you hands-free calls, volume adjustment and track skipping — the description spells out answer/hang up, high/low volume and previous/next track, with those remote functions called out for iPhone and iPod.
There's also a stated commitment to customer satisfaction, with the brand saying it will stand behind buyers even after the guarantee date and inviting messages through Amazon. That's a support posture rather than a spec, but it's part of how they position the cable, and it's worth knowing if you're the type who wants a fallback path if a replacement part misbehaves. Who should skip it? If you own QC15 specifically and want a simple black drop-in, the Alitutumao is the cleaner match — you don't need a 2.5mm adapter end to get there. And if your setup only ever uses one jack size, the dual-plug design is more cable than you strictly need.
Side-by-Side: Which Should You Choose?
• Best for Bose QC15 owners → Alitutumao Replacement Audio Extension. It's built specifically for that headphone, in black, at 140cm.
• Best for longer reach → EARLA TEC. Roughly 1.5m versus 140cm on the Alitutumao.
• Best for a short, tidy cord at a desk → Alitutumao. 140cm keeps things close and the cable is described as tangle-free.
• Best for mixed devices (phone, laptop, PC) → EARLA TEC. Its compatible-devices list explicitly includes laptops and PCs; the Alitutumao list is smartphone, tablet and music player.
• Best if you need an L-shaped plug for a recessed jack → EARLA TEC. It's the only one of the two offering a straight plug and an L-shaped plug.
• Best if you want an extra bass headphone for Xbox pairing to stay wired and stable → EARLA TEC. The 3.5mm-to-2.5mm adapter design is the more console-friendly configuration, and a wired inline mic avoids the sync headaches wireless can bring.
• Best if you just want to restore talk, volume and music control on an existing QC15 → Alitutumao. Both cables offer inline mic and volume control, but the Alitutumao is the direct part for that headphone.
If you own Bose QuietComfort 15, I'd buy the Alitutumao Replacement Audio Extension. It's the correct part for that headphone, it keeps the inline mic and remote controls you already rely on, and the 140cm tangle-free OFC cord is exactly what a replacement should be — unremarkable in the best way. For Xbox sessions where you want a wired, low-latency link and a mic you can actually talk through, I'd lean EARLA TEC instead: the 1.5m length, the straight-plus-L plug pair and the 3.5mm-to-2.5mm adapter design give you far more room to work with, and it covers QC25, QC35, SoundLink, SoundTrue, phones, laptops and PCs in one cable. That breadth is why I'd recommend EARLA TEC to most people who aren't locked into a QC15. If you're weighing a voice assistant in ear headphones for Xbox or noise cancelling earphones for Xbox, remember this cable only replaces the cord — the headphone and its features stay the same, so match the cable to the model you already own. Check the current price on Amazon before you commit.
FAQ
It's a small microphone built into the headphone cable itself, usually paired with a button module. Both cables here include one: Alitutumao bundles talk, volume and music control, and EARLA TEC offers hands-free calls plus volume and track buttons.
Plug the cable into your headset and the other end into your PC's audio jack, then select that input in your sound settings. EARLA TEC lists laptops and PCs as compatible devices, so it's the better-documented option of the two for that setup.
No. Alitutumao states compatibility with the Bose QuietComfort QC15 only. If you own QC25 or QC35, the EARLA TEC cable is the one that lists those models.
Alitutumao measures 140cm, about 4.6 feet. EARLA TEC measures roughly 1.5 metres, so it gives you noticeably more slack — useful if you're sitting further from your source or gaming from a couch.
