If you want sealed in-ear isolation with ENC call clarity and quick-charge convenience for meetings and commuting, choose HARMONY TWENTY-TWO HTT-21; if you need open-ear awareness, feather-light comfort and marathon playtime for running, cycling and all-day wear, choose WIVTAK Open Ear Headphones.
• HARMONY TWENTY-TWO HTT-21 — biggest strength: Four-mic ENC call noise cancelling, a 13mm dynamic driver and Bluetooth 5.4 in a compact in-ear design, with a 10-minute quick charge that yields 100 minutes of playback and roughly 6 hours per charge (up to 40 hours with the case).
• HARMONY TWENTY-TWO HTT-21 — biggest trade-off: It is an in-ear earbud with IPX5 protection, not an open-ear design, so it physically blocks your ear canal and you lose the ambient awareness that runners and cyclists often want.
• WIVTAK Open Ear Headphones — biggest strength: Open-ear air-conduction design at just 0.28oz with ergonomic earhooks, physical buttons to eliminate touch errors, a claimed 62-hour playtime, multipoint Bluetooth 5.4 and 98% ambient noise filtering for calls.
• WIVTAK Open Ear Headphones — biggest trade-off: The open-ear fit means no sealed bass and no passive isolation, the stated single-charge battery life in the spec sheet reads just 1 hour (the 62H figure refers to total playtime with the charging station), and charging takes 2 hours.
• Who each pick is for: HARMONY TWENTY-TWO HTT-21 suits anyone who lives on calls and wants quiet, focused listening; WIVTAK Open Ear Headphones suit runners, cyclists and all-day wearers who refuse to block out the world.
The HTT-21 is built around one job: making your voice sound clear when you're on a call. It carries ENC — Environmental Noise Cancellation — across four microphones, which works on the sound picked up at your end so the person you're talking to hears you rather than the café, the street or the train carriage. That is a different job from ANC, which reduces what you hear. Both appear in the spec sheet here, but if your priority is being understood during meetings, the ENC side is the one that matters.
Buy it if you take a lot of calls, want voice-assistant access by touch or hands-free, and like the idea of in-ear buds that stay small and pocketable. Skip it if you want to hear traffic while you run, or if you dislike anything sitting inside your ear canal.
WIVTAK Open Ear Headphones: Who It's For
The WIVTAK pair solves the opposite problem. Nothing enters your ear canal — the drivers sit outside and fire sound inward via air conduction, held by earhooks. At 0.28oz they're genuinely light, and the design is explicitly aimed at running, cycling and workouts where hearing your surroundings is a safety feature, not a compromise. You can hold a conversation, hear a car behind you, or share what you're listening to with someone sitting next to you.
Sound is handled by 14.2mm dynamic drivers with a LISO 2.0 bass boost and three built-in EQ modes you switch without an app — deep bass, clear vocals, or balanced. Controls are physical buttons rather than touch, which is the right call for sweaty, moving hands: skipping tracks or adjusting volume is deliberate, not accidental. Bluetooth 5.4 adds multipoint so the headphones can hop between devices, and a 5-minute charge returns an hour of playback.
Two things to weigh honestly. Open-ear means almost no bass seal and no isolation from the world around you — great outdoors, less great on a plane. And the spec sheet lists a 2-hour charge time and a 1-hour average battery life per charge, with the headline 62 hours coming from the charging station, so plan around docking them rather than expecting one giant single-charge session. The 2-year manufacturer warranty is a genuine plus.
• Best for clear calls and meetings → HARMONY TWENTY-TWO HTT-21. Four-mic ENC is the whole point of this model.
• Best for running, cycling and outdoor safety → WIVTAK Open Ear Headphones. Open-ear air conduction keeps you aware of traffic and crowds.
• Best for all-day comfort → WIVTAK Open Ear Headphones. At 0.28oz with earhooks, there's nothing pressing into your ear canal.
• Best for quick top-ups → HARMONY TWENTY-TWO HTT-21. Ten minutes of charging buys about 100 minutes of playback.
• Best for total playtime with the case → HARMONY TWENTY-TWO HTT-21. Roughly 6 hours per charge and up to 40 hours with the case is easier to live with than a one-hour single charge.
• Best for glove-and-sweat-proof controls → WIVTAK Open Ear Headphones. Physical buttons beat touch controls when your hands are busy.
• Best for sharing audio with someone nearby → WIVTAK Open Ear Headphones. The open design leaks sound by nature, which here is a feature.
• Best for commuting and noisy environments → HARMONY TWENTY-TWO HTT-21. Sealed in-ear fit plus ENC handles a busy train better than an open design.
If I had to pick one, I'd buy the HARMONY TWENTY-TWO HTT-21 for meetings, calls and general commuting. The ENC microphone array, the quick-charge math and the case-backed 40-hour playtime all point at the same buyer: someone who is on the phone a lot and wants the other person to hear them clearly. The WIVTAK Open Ear Headphones are the better choice if your day is spent moving outdoors and you value awareness and comfort over isolation. Check the current price on Amazon before you decide — that's the one variable this comparison can't settle for you.
how to use wireless headphones mic on pc
Pair the headphones over Bluetooth 5.4, then in your computer's sound settings select them as both the output device and the input device. The HTT-21 uses its ENC microphone array for calls; the WIVTAK pair uses its ENC mic for the same purpose. If your PC doesn't list them as a microphone, remove and re-pair the device.
how to use mic on wireless headphones
Once connected, the microphone is active automatically for calls and voice chat — you don't switch it on separately. On the HTT-21 you can also trigger Siri or Google Assistant with a touch or hands-free, which routes audio through the same mic path. On the WIVTAK pair, the physical button answers and ends calls.
can you use bluetooth headphones as a mic
Yes. Both of these are Bluetooth 5.4 headsets with built-in microphones, so they work as a mic for calls and voice chat. The HTT-21 leans on four-mic ENC to reduce background noise on your voice, while the WIVTAK filters a claimed 98% of ambient noise. Neither replaces a dedicated studio microphone for recording.
do all bluetooth headphones have a microphone
No. Many Bluetooth headphones are designed purely for listening, especially open-ear models aimed at music. Both products here do include microphones — the HTT-21 with ENC call noise cancelling and the WIVTAK with ENC plus AI noise cancellation — so both can be used for calls, but that isn't guaranteed across the category.
