• Kenwood KHS-34 — biggest strength: A C-ring hanger that rests outside the ear canal, so you keep ambient awareness while the in-line PTT and clip mic keep your hands free. At roughly 5.67 g it's about as light as a radio earpiece gets.
• Kenwood KHS-34 — biggest trade-off: It's a single unit with one 3.5 mm jack, and it's aimed at the Kenwood ProTalk PKT-23 series specifically. If you're running Baofeng or other Kenwood models, this isn't the plug for you.
• COMMIXC 2-Pack — biggest strength: Two headsets, a 3.5 mm + 2.5 mm two-pin connector, and a compatibility list that stretches across Kenwood ProTalk/FreeTalk and a wide range of Baofeng handhelds. Ergonomic earplugs seat inside the canal.
• COMMIXC 2-Pack — biggest trade-off: It's the heavier, bulkier option (30 g for the pack), there's no noise control listed, and the in-canal earplug blocks more of the world around you than a C-ring design.
• Who each pick is for: Kenwood KHS-34 if you want one light, open-ear headset for a PKT-23 and value comfort over coverage. COMMIXC 2-Pack if you need spares, share headsets across a small crew, or run mixed Kenwood/Baofeng radios.
The KHS-34 is a single-pin wired earpiece built around one idea: keep the ear open. Its C-ring hanger sits outside the ear rather than plugging the canal, which is the whole point of a design like this. You hear your radio traffic and the room around you — footsteps, a door, someone calling your name. For anyone working security, events, retail floors or warehouse aisles, that awareness matters more than isolation.
It's also genuinely light. The listed item weight is 5.67 g, and the earpiece can be worn on either ear, so you're not locked into one side. The in-line push-to-talk switch and clip microphone mean you can key up without pulling the radio off your belt, and the dynamic driver with 32 ohm impedance is a straightforward, low-drama spec for voice audio. Kenwood describes it as built for loud environments, which is exactly where an in-line PTT earns its keep — you're not fumbling for the radio itself.
Who should skip it? Anyone whose radios don't use a single 3.5 mm connection to the PKT-23 series. This is a targeted accessory, not a universal one, and it's a single unit — no spare in the box. If you want a headset that covers multiple radio brands or you need a second one for a partner, look at the COMMIXC instead. Note that the listing notes a Bluetooth connectivity field alongside the wired 3.5 mm jack, but the product itself is described as a wired earpiece with a physical PTT switch — treat the wired connection as the real-world use case.
The COMMIXC 2-Pack is the opposite philosophy: cover as many radios as possible, and give you two headsets while you're at it. The connector is a two-pin 3.5 mm + 2.5 mm setup with an 8.6 mm pin spacing, and the compatibility list is long — Kenwood ProTalk, FreeTalk, TK-series, NX-series, TH-series handhelds, plus Baofeng UV-5R, UV-B5, BF-888S and more. If your radio drawer is a mixed bag, this is the headset that's most likely to just plug in and work.
The earpiece itself is different from the Kenwood's open C-ring. COMMIXC uses an ergonomic earplug that seats in the ear canal, and the brand's stated goal is to reduce the "vacuum pressure" a single earbud can create so it stays comfortable over long wear and doesn't fall out. That in-canal fit means more isolation — handy in loud venues, less handy if you need to hear what's happening around you. The frequency range is listed at 20 Hz to 20,000 Hz, and the pins are electroplated for anti-oxidation, which is a real-world detail aimed at avoiding the intermittent contact that kills cheap headsets over time.
The PTT microphone clips to your clothing, there's a cord between mic and earpiece for reach, and setup is plug-and-play — no pairing, no menu. COMMIXC lists a 1-year manufacturer warranty and the pack contains two units, which makes it the practical pick for a two-person team or anyone who wants a backup. The trade-off is honest: it's heavier as a package at 30 g, there's no noise control listed, and the in-ear plug cuts you off from your surroundings more than the Kenwood does.
• Best for open-ear awareness → Kenwood KHS-34. The C-ring rests outside the canal, so you stay tuned in to your environment.
• Best for radio compatibility → COMMIXC 2-Pack. Two-pin 3.5/2.5 mm with a broad Kenwood + Baofeng model list beats a single-pin PKT-23-specific design.
• Best for lightest wear → Kenwood KHS-34. 5.67 g versus a 30 g two-headset pack; the Kenwood disappears on your ear.
• Best for spares or sharing → COMMIXC 2-Pack. Two headsets in one purchase, plus a 1-year manufacturer warranty.
• Best for loud, isolated environments → COMMIXC 2-Pack. The in-canal earplug seals more sound out while you talk.
• Best for mixed-brand crews → COMMIXC 2-Pack. One box covers Kenwood and Baofeng radios; the Kenwood covers only its own PKT-23 line.
• Best for dedicated PKT-23 users → Kenwood KHS-34. If every radio you own is a ProTalk PKT-23, the single-pin fit is the clean, no-adapter answer.
• Best for long-shift comfort with canal-free fit → Kenwood KHS-34. Either-ear C-ring design for extended use.
If I owned Kenwood ProTalk PKT-23 radios and wanted one headset that stays comfortable and keeps me aware of my surroundings, I'd buy the Kenwood KHS-34. The C-ring design and 5.67 g weight are exactly what I'd want on a long shift, and the in-line PTT is where it needs to be.
But for most people, I'd lean COMMIXC 2-Pack. The two-pin connector covers a far wider spread of Kenwood and Baofeng radios, you get two headsets instead of one, and the in-canal earplug plus electroplated pins make it the more versatile, longer-lived buy. In my opinion, that flexibility wins for anyone who isn't locked into a single radio model.
FAQ
No. The KHS-34 uses a single 3.5 mm jack designed for the Kenwood ProTalk PKT-23 series. Baofeng handhelds generally use a two-pin 3.5/2.5 mm connection, which is what the COMMIXC 2-Pack provides.
It depends on what "better" means to you. The COMMIXC's in-canal earplug isolates more sound, which suits loud venues. The Kenwood KHS-34 rests outside the ear, so you hear your radio and the room — better for security or coordination work where awareness matters.
Yes. The pack contains two units, which is why it suits two-person teams or anyone who wants a spare. The Kenwood KHS-34 is sold as a single earpiece.
