How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear headset built for calls and all-day workwear comfort, choose ShenzhenShokzCo.Ltd OpenComm2; if you need a wired, over-ear headphone tuned for critical listening and studio-style monitoring, choose Linsoul Kiwi Ears Altruva.
• ShenzhenShokzCo.Ltd OpenComm2 — biggest strength: Bone conduction with an open-ear fit, a noise-canceling mic with DSP, and a USB-A wireless adapter that keeps a PC or Mac connection stable while staying Zoom-Certified.
• ShenzhenShokzCo.Ltd OpenComm2 — biggest trade-off: It's a wireless work headset, not a hi-fi music tool — no wired jack, and noise control is listed as None, so isolation isn't the point.
• Linsoul Kiwi Ears Altruva — biggest strength: A 50mm dynamic driver tuned to a studio-monitor profile, paired with a hybrid audiophile cable built to minimize signal loss and widen frequency response.
• Linsoul Kiwi Ears Altruva — biggest trade-off: It's a wired, analog-style listening headphone. There's no battery, no mic spec, no wireless adapter, and nothing here is aimed at meeting software.
• Pick the OpenComm2 if your day is meetings, calls, and being reachable while your ears stay open to the room.
• Pick the Altruva if your day is music, mixes, and hearing a track properly through a cable.
The OpenComm2 is a work tool first. It's an open-ear headset at just 35g, built on a nickel-titanium alloy frame with a soft silicone finish that's rated IP55 water-resistant — the kind of spec sheet that says "wear it through a long shift" rather than "baby it on a desk." The bone conduction driver sits outside your ear canal, so you hear your audio and your surroundings at the same time. For anyone who needs to stay aware of a shared office, a warehouse floor, or a household while on a call, that's the whole reason to buy it.
The call side is where the details stack up. Shokz uses its 7th-generation bone conduction technology with PremiumPitch 2.0 audio and a noise-canceling microphone with DSP, which is the part that matters most if you're the person everyone struggles to hear on Zoom. The Loop120 USB-A wireless adapter is included specifically to keep a PC or Mac connection stable, and the headset is Zoom-Certified, so the conferencing software side is meant to just work. Controls are physical buttons on the headset: volume, mute and unmute, play and pause. I like that for calls — a real mute button beats hunting through a menu mid-sentence.
Battery is stated as up to 16 hours of talk time and 8 hours of listening time, with a 5-minute quick charge giving 2 hours of talk time. Bluetooth 5.1, a 98-foot range, and a 1-hour charge round it out. Who should skip it? Anyone shopping for critical music listening, deep bass, or isolation. There's no headphone jack, and noise control is listed as None — this is deliberate open-ear design, not a noise-canceling headphone.
The Altruva is the opposite kind of product, and that's the point. It's an over-ear headphone with a 50mm dynamic driver, tuned to a studio monitor-like sound profile. Linsoul describes the bass as hitting hard and fast — a thumpy kick that doesn't smear the midrange — with a natural, balanced middle that keeps instruments and vocals accurate in their fundamental ranges. If you've ever put on a bass-heavy consumer headphone and wondered where the vocals went, this tuning is the answer to that complaint.
The bundle also includes the Tripowin Nova monitor cable, a 3.5mm over-ear wire built with a 4-strand hybrid architecture (Silver Foil 7x0.25mm plus OCC 10x0.08mm). The claim behind that construction is less signal loss and a wider frequency response — the kind of detail that matters to someone who already cares about cables, and is simply a nice extra to everyone else.
Who should buy it? Someone who listens at a desk or in a chair, plugged into a source, and wants a monitor-style signature for music, mixing, or just paying attention to a record. Who should skip it? Anyone who needs wireless freedom, a built-in microphone for calls, meeting-software certification, or a battery. None of that is in this spec sheet, and it isn't pretending to be. This is a wired listening headphone, and it should be judged that way.
• Best for work calls and meetings → ShenzhenShokzCo.Ltd OpenComm2. Noise-canceling mic with DSP, physical mute button, Zoom-Certified, and an included USB-A adapter for stable PC or Mac connection.
• Best for listening to music critically → Linsoul Kiwi Ears Altruva. 50mm dynamic driver with a studio-monitor tuning and a hybrid audiophile cable in the box.
• Best for all-day wear → ShenzhenShokzCo.Ltd OpenComm2. 35g, flexible frame, soft silicone, IP55 water resistance.
• Best for battery life and quick top-ups → ShenzhenShokzCo.Ltd OpenComm2. Up to 16h talk time, 8h listening, and a 5-minute charge for 2h of talk time.
• Best for staying aware of your surroundings → ShenzhenShokzCo.Ltd OpenComm2. Open-ear bone conduction leaves your ears uncovered by design.
• Best for bass impact and vocal accuracy → Linsoul Kiwi Ears Altruva. Hard, fast low end with a balanced midrange, per the stated tuning.
• Best for cable-first, no-battery listening → Linsoul Kiwi Ears Altruva. Wired 3.5mm connection, nothing to charge.
• Best for hybrid setups → both, in different roles. The OpenComm2 for the workday, the Altruva for the listening session afterward.
In my opinion, these two don't really compete — they cover different halves of a day. If I had to buy one and only one, I'd take the ShenzhenShokzCo.Ltd OpenComm2, because it solves a problem most people actually have on a schedule: being on calls, being heard clearly, and staying reachable for up to 16 hours without something jammed in my ears. I'd recommend the Linsoul Kiwi Ears Altruva to anyone whose priority is sound quality first and who listens at a desk with a cable — that 50mm monitor-tuned driver is the reason to pick it. Buy the one that matches your day, not the one with more features.
The OpenComm2, clearly. It has a noise-canceling mic with DSP, a dedicated mute button, Zoom certification, and an included USB-A wireless adapter for a stable PC or Mac link. The Altruva's spec sheet lists no microphone or conferencing features at all.
Nothing in its data sheet lists a microphone, Bluetooth, or a battery. It's a wired over-ear headphone using a 3.5mm Tripowin Nova cable, so plan on plugging it into a source.
The Altruva, in my opinion. Its 50mm dynamic driver is tuned for a studio-monitor profile with hard, fast bass and a balanced midrange. The OpenComm2 is built around calls and awareness, with an open-ear design and no noise control listed.
I can't quote prices here, and both products sit in very different categories, so the honest move is to check the current price on Amazon for each and compare them against what you actually need — calls and battery, or wired sound quality.
