If you want a listen-only acoustic-tube earpiece that keeps your radio traffic private while leaving your hands free, choose ERIPHA 3.5mm; if you need a two-pin headset with a push-to-talk mic so you can actually transmit, choose COMMIXC 2-Pack.
• ERIPHA 3.5mm — biggest strength: a single 3.5mm right-angle plug with a transparent acoustic tube and two swivel clips, so you hear incoming audio discreetly and keep both hands on the job.
• ERIPHA 3.5mm — biggest trade-off: it's listen-only. There is no push-to-talk button and no microphone on the headset itself, so you speak through your radio or a shoulder speaker mic instead.
• COMMIXC 2-Pack — biggest strength: a full two-pin (3.5mm + 2.5mm) headset with an in-line push-to-talk mic and clip, so you can both hear and transmit without touching the radio body.
• COMMIXC 2-Pack — biggest trade-off: it only fits radios with a two-pin jack (8.6mm pin spacing), which rules out anything with a single 3.5mm socket.
• Who each pick is for: ERIPHA for single-jack radios and anyone who mainly needs to listen; COMMIXC for Kenwood and Bao Feng two-pin radios where you need to talk back.
The ERIPHA 3.5mm is a listen-only acoustic-tube earpiece built around one very specific job: getting radio audio into your ear quietly, without a speaker blaring into the room. The transparent acoustic tube does the heavy lifting here — it carries sound up from the plug to the earbud, which is exactly why this style shows up in loud or crowded environments where a speaker would either be drowned out or draw unwanted attention. The plug itself is a right-angle 3.5mm with an electroplated anti-oxidation coating, and it's designed to pair with a mic that has a 3.5mm jack, like a shoulder speaker microphone or a radio worn near the chest.
What I like about the design is how much thought went into wearing it, not just hearing through it. You get two swivel clips that twist 180 degrees and lock onto clothing, plus a reinforced PU cable and a durable coil cord that gives you length flexibility depending on where the radio sits. The soft, skin-friendly acoustic-tube earbud is shaped to fit either ear and is meant for long stretches of wear, and the package includes two replacement mushroom earbuds on top of the two headsets. That's the kind of spare-parts thinking that matters if you're running a small security or hospitality team where buds get lost.
COMMIXC 2-Pack: Who It's For
The COMMIXC 2-Pack is the other half of the equation: a proper two-way headset with an in-line push-to-talk microphone, so the whole conversation — listening and talking — runs through the earpiece and mic rather than the radio's own speaker. The connector is the headline spec: a two-pin standard jack at 3.5mm + 2.5mm with 8.6mm pin spacing, electroplated to resist oxidation and avoid the poor-contact gremlins that plague cheap headsets. That pin layout is what makes it a direct fit for a long list of Kenwood ProTalk/FreeTalk models (TK208 through TK3400 series, TH handhelds, NX-220/230/240/320) and Bao Feng handhelds (UV-5R family, UV-B5, BF-888S, UV-3R, UV-6, and more).
The earpiece itself is a rounded-tip plug that seats into the ear canal. COMMIXC frames the ergonomics around reducing the vacuum pressure you get from a single-headphone-style bud, which is a real annoyance on long shifts, and claims it stays put without tiring your ear. Sound is handled by a dynamic driver rated 20 Hz to 20,000 Hz, with the company emphasizing crisp output in noisy places. The PTT mic clips to your clothing, and the cord between mic and earpiece is sized to give you room to move. No setup, no pairing — plug into the radio and go.
Buy the COMMIXC 2-Pack if you run a Kenwood or Bao Feng two-pin radio and you need to transmit, not just listen — covert or stealth work, event staff, retail, security patrols, anyone who wants push-to-talk at their collar instead of fumbling for the radio. Skip it if your radio only has a single 3.5mm socket, or if you specifically want the acoustic-tube listening style. It's a 2-pack, adult sizing, 1-year manufacturer warranty, and it weighs about 30 g.
Side-by-Side: Which Should You Choose?
• Best for discreet listening only → ERIPHA 3.5mm. The acoustic tube routes audio to your ear with no outward speaker, which is the point of this design.
• Best for single 3.5mm-jack radios → ERIPHA 3.5mm. One right-angle plug, works with a 3.5mm mic or shoulder speaker mic.
• Best for Kenwood/Bao Feng two-pin radios → COMMIXC 2-Pack. The 3.5mm + 2.5mm pins at 8.6mm spacing are built for that family of radios.
• Best for long-wear comfort → COMMIXC 2-Pack on paper, given the ergonomic ear-canal tip designed to reduce vacuum pressure; ERIPHA counters with a soft acoustic-tube bud for either ear.
• Best for hands-free cable management → ERIPHA 3.5mm. Two 180° swivel clips plus a coil cord give you more ways to route the cable.
• Best for spare parts in the box → ERIPHA 3.5mm. You get two replacement mushroom earbuds alongside the two headsets.
• Best all-rounder for a mixed team → it depends on your radios, not your budget — check which jack your radios use first, then pick the matching headset.
In my opinion, the connector on your radio decides this before anything else, so start there. For a two-pin Kenwood or Bao Feng handheld where you need to key up and talk, I'd buy the COMMIXC 2-Pack — the in-line PTT mic and the 20 Hz–20,000 Hz dynamic driver make it the more complete communication tool. For a single 3.5mm radio and a job that's mostly listening — security, hospitality, noisy floors — I'd take the ERIPHA 3.5mm for its acoustic tube, swivel clips, and spare earbuds. If you truly need both, they're cheap enough to own as a pair, and the current price is worth checking on Amazon before you commit.
Ear pieces (often written "earpieces") are the small in-ear components that deliver audio from a radio or headset into your ear. In two-way radio gear they come in styles like acoustic-tube buds or ear-canal plugs, and both products here are 2-packs of that kind of earpiece.
For singers, earpieces are in-ear monitors that feed a mix of vocals and instruments back to the performer on stage. That's a different job from these radio earpieces — the ERIPHA and COMMIXC units are built for walkie-talkie and two-way radio communication, not stage monitoring.
They're the earpiece portion of a headset — the part that sits in the ear — as opposed to the cable, plug, or microphone. On the ERIPHA that's a soft acoustic-tube bud; on the COMMIXC it's a rounded-tip plug that inserts into the ear canal.
They act as in-ear monitors, letting a performer hear a controlled mix without stage wedges. Radio earpieces like these do something similar but simpler: they keep incoming radio audio private, and on the COMMIXC the attached PTT mic also lets you transmit.
