• Retevis RT22 — biggest strength: a K-head 2-pin wired earpiece with a mushroom in-ear earhook, a face-up PTT button and a sensitive mic, so you can talk on a compatible two-way radio without holding anything.
• Retevis RT22 — biggest trade-off: it's a wired accessory, not a standalone Bluetooth headphone, and it's designed around radio use rather than music or general phone audio.
• DHBY Sport Earbuds Headphone — biggest strength: true wireless stereo Bluetooth 5.0 with touch control, one-step pairing and a 20Hz–20,000Hz dynamic driver for full-range sound.
• DHBY Sport Earbuds Headphone — biggest trade-off: it's wireless only with no jack, and it relies on passive noise cancellation rather than active noise control.
• Who each is for: Retevis RT22 for radio, security, events and noisy-jobsite talk; DHBY for music, calls and webinars from a phone or laptop.
This is a walkie-talkie earpiece, and it makes no apology for it. The K-head 2-pin connector is the whole point: it's built to plug into a long list of compatible radios — Retevis RT22, RT21, RT68, RT68H, H777, RT27, RT86 and more, plus Pxton, Baofeng BF-888S/BF-T26 and Kenwood two-way radios. If you already own one of those, this drops straight in. If you don't, this isn't the product for you.
Where it earns its keep is in the ear and on the cable. The mushroom earplug rotates, so you can fit it to your left or right ear, and the earhook is designed to stay put without pressing on your ear over long shifts. The PTT button faces up so a single touch starts a call, and the mic is tuned for clear pickup even when things get loud around you. The movable fixing clip lets you pin the cable to a collar or shirt, and you can coil the cable onto it to stop tangling.
The audio spec tells you what it's for: a 16-ohm dynamic driver with a 300Hz–3400Hz frequency range. That's a narrow band — exactly the range human speech lives in. It's not a music headphone and it was never meant to be. Battery average life is listed at 10 hours, and it's wired, so this is about the connected radio setup rather than the earpiece holding a charge on its own. In my opinion, the right buyer is someone doing security, events, hospitality, warehouse or site work who wants private, hands-free voice and doesn't want to fiddle with Bluetooth pairing. Skip it if you want music, wireless freedom, or you don't own a compatible radio.
This one is a completely different animal. It's a true wireless stereo pair with Bluetooth 5.0, and the design brief is clearly "wear it all day and move." The 20Hz–20,000Hz dynamic driver covers the full audible range, so music, podcasts and voice all land properly. Bluetooth 5.0 gives you stable, tangle-free transmission, and pairing is a one-step job: lift both earbuds out of the charging box, they connect to each other, then you pair once in your phone's Bluetooth settings. That simplicity matters if you're the kind of person who wants to start a webinar without a five-minute setup ritual.
Control is by finger touch — a light tap answers or dials calls, plays or pauses, skips tracks, and powers the buds on or off. The fit is the ergonomic in-ear shape in skin-friendly silicone, and the brand's own framing is "no pain whole day," which is the claim to test against your own ears. It's also described as waterproof, aimed at sweat during sport. Noise handling is passive noise cancellation, which means the sealed in-ear fit does the blocking rather than electronics.
Here's the honest trade-off. There's no headphone jack — it's wireless only. Passive noise cancellation won't match active systems in a genuinely loud room. And on-ear touch controls can misfire if you're wearing a hood or adjusting the bud. For webinars, though, the combination of a full-range driver, in-call stereo sound and touch controls is a sensible fit — and if fast charging bluetooth earbuds for webinars is what you're after, the charging-box workflow is exactly the pattern to look for here. I'd recommend it for people who want music and calls from a phone or laptop, not for anyone who needs to talk into a two-way radio.
• Best for two-way radio talk → Retevis RT22. The K-head 2-pin plug and PTT button exist for exactly that.
• Best for music and full-range audio → DHBY Sport Earbuds Headphone. A 20Hz–20,000Hz driver versus a 300Hz–3400Hz speech band is not a close call.
• Best for wireless freedom → DHBY Sport Earbuds Headphone. Bluetooth 5.0, true wireless, no jack, no cable.
• Best for private, hands-free voice on a compatible radio → Retevis RT22. The mushroom earhook keeps the audio in your ear and off the room.
• Best for long-wear comfort in one ear → Retevis RT22. It's designed to rotate to either ear and sit without pressure.
• Best for touch control and one-step pairing → DHBY Sport Earbuds Headphone. Tap to answer, tap to skip, pair once.
• Best for a loud, messy environment → Retevis RT22. The sensitive mic is built to hold up when there's noise around you.
• Best for workouts and sweat → DHBY Sport Earbuds Headphone. Silicone fit and a stated waterproof build.
• Best for mixed multi-brand radio fleets → Retevis RT22. It lists compatibility with Retevis, Pxton, Baofeng and Kenwood radios.
If your day is built around a two-way radio and you want private, hands-free voice that never needs pairing, I'd buy the Retevis RT22 — the 2-pin compatibility, face-up PTT and speech-tuned 300Hz–3400Hz driver are all pointed at that job. If your day is built around a phone or laptop — music, calls, and running webinars where you want to tap to mute and move freely — I'd buy the DHBY Sport Earbuds Headphone for its Bluetooth 5.0 wireless design, touch controls and full-range 20Hz–20,000Hz driver. Two different tools, two different jobs. Match the product to the job and you'll be happy either way. Whatever you decide, check the current price on Amazon before you commit.
An in-ear headset is a device whose speaker sits inside your ear canal rather than over your ear. Both products here are in-ear designs: the Retevis RT22 uses a rotatable mushroom earplug on an earhook, and the DHBY Sport Earbuds Headphone uses a rounded-tip silicone earbud.
What is over ear headset?
An over-ear headset has cups that sit around or on top of your ear instead of inside it. Neither product on this page is over-ear — the Retevis RT22 is listed as In Ear and the DHBY Sport Earbuds Headphone is listed as In Ear, so if you specifically want over-ear cups, keep looking.
For the Retevis RT22, rotate the mushroom earplug to the direction you need and slot it into your chosen ear, then clip the cable to your clothing so it stays in place. That single-ear setup is exactly what it's designed for. The DHBY pair is a two-earbud TWS design, so it isn't meant to be worn in one ear only.
If you mean getting an earpiece to sit comfortably rather than forcing it, the trick is angle, not pressure. On the Retevis RT22 you adjust the rotatable earplug to match your ear's shape so it sits without pressing. On the DHBY Sport Earbuds Headphone, the rounded silicone tip is built for a soft, ergonomic fit — try a gentle twist rather than pushing straight in.
