If you want a drop-in replacement cable that restores inline mic and volume/track control on Beats by Dr. Dre headphones, choose EARLA TEC Replacement Audio Cable; if you need a general-purpose 3.5mm aux cord for car stereos, speakers and everyday wired listening, choose QianLink 2.
• EARLA TEC Replacement Audio Cable — biggest strength: built-in inline microphone and remote control, with one straight and one L-shaped 3.5mm male plug to fit recessed or awkward headphone jacks.
• EARLA TEC Replacement Audio Cable — biggest trade-off: the remote functions only work on Apple iPod, iPad and iPhone — not on Samsung or other non-Apple devices.
• QianLink 2 — biggest strength: a double-braided nylon jacket rated for 20,000+ bends, with gold-plated connectors and a pure copper shell aimed at reducing signal loss.
• QianLink 2 — biggest trade-off: no microphone and no inline controls, so it is purely a playback cable — and it ships as a 3.3ft/1m cord, which is shorter than EARLA TEC's 1.4m.
• Buy EARLA TEC Replacement Audio Cable if you own Beats Solo/Studio/Pro/Mixr/Executive/Pill headphones and want the cable to double as a headset on an iPhone.
• Buy QianLink 2 if you want one tough, tangle-free aux cord for a car stereo, home speaker or wired headphones and you don't need a mic.
This is a replacement cord first and a listening cable second. EARLA TEC builds it around Beats by Dr. Dre headphones — Solo, Studio, Pro, Detox, Mixr, Executive and Pill are all named as compatible — with a 3.5mm plug at each end, two male plugs, one straight and one L-shaped. That L-shaped end matters more than it sounds: on headphones where the jack sits flush against your shoulder or a folded hinge, an angled plug takes the strain off the connector instead of levering against it.
The catch is the Apple-only remote. EARLA TEC states plainly that the remote function works on Apple iPod, iPad and iPhone and not on Samsung or other non-Apple devices. So buy this if you're an iPhone user with Beats headphones and you want one cable that handles both music and calls. Skip it if you're on Android — you'd be paying for a control pod that won't respond — or if you need a cable for a car stereo or speaker, where a plain aux cord does the job.
QianLink 2: Who It's For
QianLink 2 takes the opposite approach: no controls, no mic, just a well-built length of audio cable. It's a 3.3ft/1m 3.5mm TRS aux cord with a double-braided nylon exterior that QianLink rates at 20,000+ bends, plus 24k gold-plated connectors and a pure copper shell intended to reduce signal loss. The core is enameled wire, and QianLink markets the whole assembly as Hi-Fi stereo transmission.
The compatibility story is the real selling point. Any device with a standard 3.5mm aux port is fair game — car stereos, home stereos, speakers, iPods, iPads, laptops, MP3 players, wireless audio receivers, radios, Echo Dot and headphones from Sony, Beats, Bose and others. QianLink's own list includes iPhone models that need an Apple Lightning adapter, so older iPhones work too, just with the adapter in the chain. It ships as a two-pack in a sealed anti-static bag, which is genuinely useful: one cable lives in the car, one lives in a bag, and you stop unplugging the same cord every morning.
Two things to weigh honestly. First, it's 1m, not 1.4m — fine for a phone in your lap or a speaker on a shelf, tighter if you like to roam. Second, there's no inline mic, so this is not a headset cable. Buy it if you want a durable, tangle-free aux cord for wired listening across several devices. Skip it if you specifically need call handling or volume buttons on the wire.
• Built-in mic and call handling → EARLA TEC Replacement Audio Cable. It's the only one of the two with an inline microphone.
• Inline volume and track control → EARLA TEC Replacement Audio Cable — but only on Apple iPod, iPad and iPhone.
• Android users → QianLink 2. EARLA TEC's remote doesn't work on Samsung or other non-Apple devices.
• Beats headphone owners replacing a broken cord → EARLA TEC Replacement Audio Cable, given the named Solo/Studio/Pro/Mixr/Executive/Pill compatibility.
• Car stereo, home stereo, speaker or Echo Dot → QianLink 2. Universal 3.5mm fit with no controls to get in the way.
• Longer reach → EARLA TEC Replacement Audio Cable at 1.4m versus QianLink 2's 3.3ft/1m.
• Ruggedness and tangle resistance → QianLink 2, with its double-braided nylon jacket and 20,000+ bend rating.
• Recessed or tight headphone jacks → EARLA TEC Replacement Audio Cable, thanks to the one straight plus one L-shaped plug.
• Best for keeping spares around → QianLink 2, since it arrives as a two-pack.
In my opinion, the deciding question isn't which cable is "better" — it's whether you need a headset cable or a listening cable. If you own Beats headphones and use an iPhone, I'd buy the EARLA TEC Replacement Audio Cable: the inline mic and remote turn one cord into your music and call setup, and the L-shaped plug plus 1.4m length are the details that make it feel purpose-built. If you're on Android, or you mainly want an aux cord for a car, speaker or home stereo, I'd buy QianLink 2 — the braided build and two-pack make far more sense for that job. Check the current price on Amazon before you commit, since value depends on what you're replacing.
how to make aux cable with headphones
You don't build one — you buy a cable with a 3.5mm male plug at each end and connect it between your headphones' aux input and your phone, laptop or stereo. QianLink 2 is exactly that: a 3.5mm TRS male-to-male cord that works with any device with a 3.5mm aux port. EARLA TEC does the same job, but adds a mic and remote and is aimed at Beats headphones specifically.
how to use wired headphones without headphone jack
how do i connect my wired headphones to my phone
Plug the 3.5mm end into your phone's headphone jack and the other end into the headphones. If your headphones use a detachable cord, the EARLA TEC Replacement Audio Cable connects the two with its two male 3.5mm plugs — one straight, one L-shaped. If your phone lacks a jack, you'll need an adapter, and QianLink 2 handles that setup on iPhone models that require a Lightning adapter.
Do I need an inline microphone in an aux cable?
Only if you take calls or use voice commands through the cable. EARLA TEC's inline mic and remote support hands-free calls, volume, track skipping and Siri on Apple iPod, iPad and iPhone. If you only listen to music — in a car, on a speaker or on headphones — QianLink 2's plain 3.5mm design is simpler and has nothing to break.
