If you want a single cable that turns a pair of AKG studio headphones into something you can plug into a phone, laptop, or amp, choose weishan K702; if you need lightweight open-ear earbuds that stay put while you run, walk the dog, or take calls, choose ACANDYA 3.5mm.
• weishan K702 biggest strength: A coiled mini-XLR female to 3.5mm male TRS cable with a screw-on 6.35mm adapter, extending from 4 feet to 15 feet — built for AKG-style headphones and gear with a 1/8" or 1/4" jack.
• weishan K702 biggest trade-off: It is a cable, not a listening device. If you don't already own compatible headphones, or your gear doesn't use a mini-XLR connector, this does nothing for you.
• ACANDYA 3.5mm biggest strength: Open-ear hook design with flexible ear loops, a built-in noise-cancelling microphone, and inline volume control — made for movement and calls.
• ACANDYA 3.5mm biggest trade-off: Open-ear means you hear your surroundings, which is great for safety and awareness but not for blocking out noise. There is no isolation-focused fit here.
• Who weishan K702 is for: Owners of AKG Q701/K702/K712/K240-family headphones (or Pioneer HDJ-2000) who need a longer, coiled replacement cable and an adapter for amps or consoles.
• Who ACANDYA 3.5mm is for: Runners, gym-goers, students, and commuters who want lightweight earbuds that stay on the ear and let them stay aware.
The weishan K702 is a purpose-built replacement cable. One end is a mini-XLR female connector; the other is a 3.5mm TRS male plug, and the package also includes a 6.35mm (1/4") screw-on adapter. That combination matters because it covers two very different worlds: portable devices with a standard 1/8" jack (phones, tablets, laptops, MP3 players, car stereos) and pro/studio gear that expects a 1/4" connection (consoles, amplifiers, speakers, guitars, pianos, drums).
Who should buy it? If you own AKG Q701, K702, K712, K240, K240S, K240 MK II, K141, K171, K181, K271, K271S, K271 MK II, K241, K175, K275, K712 PRO, K553 MKII, or M220 headphones — or Pioneer HDJ-2000 — and your stock cable is too short, worn out, or terminated in a plug your gear won't accept, this is a direct fix. The screw-on 6.35mm adapter is the quiet hero here: it means one cable can serve both your phone and your amplifier.
Who should skip it? Anyone who doesn't own compatible headphones. If your headphones use a standard 3.5mm socket rather than a mini-XLR, this cable has no way to connect. And if you're shopping for something to actually listen with, this isn't that product — it's the link between your headphones and your source.
ACANDYA 3.5mm: Who It's For
The ACANDYA 3.5mm is a wired open-ear sport headset. The defining design choice is the ear-hook shape: flexible loops wrap around the ear to hold the earbuds in place during running, gym work, or any rigorous activity. Because the earpieces sit open rather than sealing into the ear canal, you stay aware of traffic, people, and your surroundings — which is exactly why this style has become popular with runners and dog walkers.
Comfort is the second pillar. The ergonomic flexible earhooks are built to hang stable without falling, and the looser, lightweight fit is designed to stay comfortable even after long sessions. The enclosure uses aluminum, the color is black, and a black protective carrying case is included — a small but genuinely useful detail for tossing the earbuds in a bag.
Audio-wise, the specs list 32 ohm impedance and a 20Hz–20,000Hz frequency range, which is a standard full-range figure for this class of earbud. There's a built-in noise-cancelling microphone for calls, and the control method is push-button with inline volume control, so you can answer and end calls without pulling out your phone. Connection is wired 3.5mm — no pairing, no charging, no battery anxiety.
Who should skip it? If your priority is blocking out noise — on a plane, on a loud train, in a shared office — open-ear is the wrong tool. There's no isolation here by design. And if your device has no 3.5mm jack, you'll need an adapter, since this is strictly a wired 3.5mm connection.
Side-by-Side: Which Should You Choose?
• Best for replacing a worn AKG headphone cable → weishan K702. The mini-XLR female connector is the whole point.
• Best for reach and flexibility → weishan K702. The coiled design stretches from 4 feet to 15 feet.
• Best for studio and stage gear → weishan K702. The included screw-on 6.35mm adapter covers amplifiers, consoles, and instruments.
• Best for running, gym, and outdoor workouts → ACANDYA 3.5mm. The ear-hook loops are built to stay put during activity.
• Best for staying aware of your surroundings → ACANDYA 3.5mm. The open-ear design deliberately leaves your ears unsealed.
• Best for hands-free calls → ACANDYA 3.5mm. Built-in noise-cancelling mic plus push-button call control.
• Best for travel and storage → ACANDYA 3.5mm. It ships with a protective carrying case.
• Best if you don't own compatible headphones → ACANDYA 3.5mm. It's a complete listening product; weishan K702 is an accessory.
These aren't interchangeable, so the real question is what you're missing. In my opinion, if you own a pair of AKG K702/Q701/K240-family headphones and need a longer, coiled cable with both 3.5mm and 6.35mm options, the weishan K702 is the smarter buy — it's a targeted fix that solves a specific, annoying problem. If instead you want earbuds for movement, calls, and staying aware while you train, I'd go with the ACANDYA 3.5mm. For most casual shoppers who don't already own compatible studio headphones, the ACANDYA is the one that actually lets you listen out of the box.
Only if your headphones use a mini-XLR connection. It's listed for AKG Q701, K702, K712, K240, K240S, K240 MK II, K141, K171, K181, K271, K271S, K271 MK II, K241, K175, K275, K712 PRO, K553 MKII, M220, and Pioneer HDJ-2000. Standard 3.5mm-socket headphones won't fit.
No — and that's intentional. It uses an open-ear design, so you hear your surroundings while you listen. If noise isolation is your goal, this isn't the right pick.
It's coiled, ranging from about 4 feet (1.4 m) up to 15 feet (5 m) when stretched, and it includes a screw-on 6.35mm adapter for amps, consoles, and instruments.
Neither does. Both are wired — the ACANDYA connects via 3.5mm jack, and the weishan K702 is a passive cable. No batteries involved.
