How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single replacement cable that revives a pair of AKG studio headphones and stretches from your desk to your chair, choose weishan K702; if you need a complete in-ear monitor with a beryllium dynamic driver tuned for balanced, audiophile-style listening, choose Linsoul Kiwi Ears Cadenza.
• weishan K702 — biggest strength: a coiled mini-XLR female to 3.5mm TRS male cable that expands from 4 feet to 15 feet, with a screw-on 6.35mm adapter included, so it covers both portable and desktop/amplifier setups.
• weishan K702 — biggest trade-off: it is a cable, not a headphone. If you don't already own a compatible AKG model (or another device that accepts mini-XLR female to 3.5mm male), it does nothing for you.
• Linsoul Kiwi Ears Cadenza — biggest strength: a 10mm beryllium dynamic driver in a 3D-printed housing, tuned toward a balanced signature with strong bass impact, quick decay, and natural, fatigue-free treble.
• Linsoul Kiwi Ears Cadenza — biggest trade-off: it's a wired 3.5mm in-ear with no noise cancelling and no wireless mode, so it's strictly for listeners who want a cable and a single-ended plug.
• Who each pick is for: weishan K702 is for AKG K240/Q701/K712/K271-family owners replacing or upgrading a cable; the Cadenza is for someone buying their first serious IEM or wanting a second, differently tuned set.
The weishan K702 is a purpose-built accessory. Its job is simple: connect headphones that use a mini-XLR female socket to sources with a 3.5mm output, and give you enough length to actually move around while you do it. The black coiled cable runs 4 feet at rest and stretches to 15 feet, which is the detail that matters most in daily use. Short enough that it doesn't pool on your desk, long enough that you can roll your chair back or stand up without yanking the plug out of your interface.
Compatibility is the whole story here. The listing names AKG Q701, K702, K712, K240, K240S, K240 MK II, K141, K171, K181, K271, K271S, K271 MK II, K241, K175, K275, K712 PRO, K553 MKII and M220, plus Pioneer HDJ-2000. That's a wide net across AKG's studio and hi-fi lines, and it means if you own one of those, you already know whether this fits. The plugs are gold-plated TRS, which is a sensible choice for reducing corrosion at the contact points over time, and the bundled 6.35mm screw-on adapter lets the same cable go from a phone or laptop into a console, amplifier, speaker, guitar, piano or drum setup. One cable, two worlds.
Linsoul Kiwi Ears Cadenza: Who It's For
The Cadenza is a different category of product entirely — it's the thing that makes sound. The core of it is a 10mm beryllium dynamic driver. Beryllium is worth talking about because of its physical properties: high tensile strength and stiffness for its mass, which lets the diaphragm move faster and more precisely. In practice, that translates to the traits the design targets — hard-hitting, responsive bass, rich mids, and clear treble, with resolution and clarity across the range.
What I find more interesting is the tuning philosophy. The Cadenza is described as acoustically tuned to a balanced, modern audiophile signature, achieved through a custom 3D-printed housing built around that 10mm driver. The bass is deliberately given a quicker decay so the mids stay natural instead of turning muddy or bloated — a common failure point in bass-forward in-ears. The treble follows a Harman-reference-style curve: smooth and non-fatiguing, but still carrying micro-details and air. On paper, that's a set designed to be listened to for hours rather than in short, exciting bursts.
Specs round it out at 32 ohm impedance and 110 dB sensitivity with a 20Hz–20KHz range, which means it should be easy to drive straight from a phone, laptop or dongle without extra amplification. It uses a detachable 0.78mm 2-pin connector and ships with a 4-core braided copper cable terminated in 3.5mm single-ended — so you can swap cables later, and if the cable ever fails, the earphones survive. The shell is plastic with a rounded-tip in-ear shape, in purple, with a one-year warranty.
Who should buy it: someone stepping up from bundled earbuds, a musician who wants an affordable wired monitor, or an enthusiast who wants a balanced, non-fatiguing tuning as a daily driver. Who should skip it: if you need wireless, active noise cancelling, or you already dislike the idea of a cable running to your phone, this isn't the tool.
Side-by-Side: Which Should You Choose?
• Best for actually buying headphones → Linsoul Kiwi Ears Cadenza. The K702 produces no sound of its own.
• Best for reach and flexibility → weishan K702. The coil stretches from 4 to 15 feet and the included 6.35mm adapter covers amps and consoles.
• Best for portable listening → Linsoul Kiwi Ears Cadenza. A 3.5mm single-ended plug, 32 ohm, 110 dB sensitivity — it's built to run off a phone or laptop.
• Best for tuning you can live with all day → Linsoul Kiwi Ears Cadenza. Balanced signature, quick bass decay, treble described as natural and free of fatigue.
• Best for long-term ownership → Linsoul Kiwi Ears Cadenza. The detachable 2-pin design means a failed cable is a cheap swap, not a dead product.
• Best for multi-device households → weishan K702. The same cable works with car stereos, tablets, laptops, MP3 players, computers and the listed AKG and Pioneer models.
• Best if you own neither and want to hear music → Linsoul Kiwi Ears Cadenza. Start with something that plays; add a cable only when you have a headphone that needs one.
If I were spending my own money and I didn't already own a compatible AKG headphone, I'd buy the Linsoul Kiwi Ears Cadenza. It's the complete product: driver, housing, cable, tuning, detachable connector. The beryllium driver and the balanced, Harman-referenced approach make it the more interesting purchase for anyone who wants to hear their music properly. The weishan K702 is genuinely good at what it does — I'd recommend it without hesitation to an AKG K240 or K712 owner whose cable has failed — but it's a repair, not an upgrade to your listening. Buy the Cadenza to listen; buy the K702 to fix.
It's a cable. Specifically a mini-XLR female to 3.5mm TRS male audio cable with a screw-on 6.35mm adapter, compatible with a long list of AKG models including the K240, K271, Q701, K702 and K712.
Yes. It terminates in a standard 3.5mm single-ended plug, and at 32 ohm impedance with 110 dB sensitivity it's designed to run from smartphones, computers and similar devices. If your phone has no headphone jack, you'll need an adapter or dongle.
They're not comparable purchases — one is a cable, one is a pair of in-ear monitors. Judge each against its own job: the K702 against the cost of replacing a compatible headphone cable, and the Cadenza against other wired IEMs with a detachable 2-pin cable. Check the current price on Amazon for both before deciding.
No. Noise control is listed as none, and the connection is wired only. It's a passive, wired in-ear monitor, so isolation comes from the fit of the rounded tips rather than electronics.
