If you want a lightweight set of everyday earbuds with strong water resistance and a voice-assistant shortcut built in, choose Motorola Sound Buds 065; if you need clearer voice calls in noisy places, a bigger bass driver and faster charging, choose HARMONY TWENTY-TWO HTT-21.
• Motorola Sound Buds 065 — biggest strength: a genuinely light, compact package (about 60 g total) with IPX4 water resistance, three sizes of silicone EarGels and Google Assistant controls — a comfortable, sweat-friendly daily pair.
• Motorola Sound Buds 065 — biggest trade-off: the battery math is modest — up to 5 hours per charge and up to 17 hours with the case, and the case itself takes around 2 hours to recharge.
• HARMONY TWENTY-TWO HTT-21 — biggest strength: ENC call noise cancelling with a four-mic setup, 13 mm dynamic drivers and fast charging that gives roughly 100 minutes of playback from a 10-minute top-up.
• HARMONY TWENTY-TWO HTT-21 — biggest trade-off: the charging case is bulkier and the total battery story is spread across a 500 mAh case rather than a slim pocket shell, and it's rated IPX5 rather than fully waterproof.
• Pick the Motorola if you want a barely-there pair for workouts, walks and podcasts, and you like hands-free Google Assistant.
• Pick the HARMONY TWENTY-TWO if most of your listening happens on calls, in cafés or on commutes, and bass depth plus fast charging matter more than a featherweight case.
The Moto Buds 065 are built around comfort and convenience. The spec sheet lists soft silicone EarGels in three sizes, an ergonomic in-ear design and a total item weight of just 60 g, so the whole kit disappears into a pocket or a bag. With Bluetooth 5.0 listed for instant pairing and a Bluetooth range of up to 15 meters, you can leave your phone on a desk or a gym bench and keep listening as you move around. Touch controls on both earbuds handle track skipping, volume and calls, and Google Assistant is baked in as a control method.
Water resistance is where this pair earns its keep. IPX4 means it shrugs off sweat and unexpected rain, which lines up with the workout-and-outdoor pitch. The audio side is a 32 ohm dynamic driver covering 20 Hz – 20,000 Hz — a standard full-range tuning that should handle most music, podcasts and video without drama. There's no headphone jack, so it's Bluetooth-only, and the box includes the earbuds, a charging case, a cable, six eartips and a manual.
The honest trade-off is stamina. Motorola lists up to 5 hours of playback per charge and up to 17 hours total with the case, and the case needs about 2 hours to charge. If you're the type who forgets to plug things in, that's a real limitation.
Buy it if you want a light, sweat-resistant, assistant-friendly pair for the gym, the commute or long walks, and you'd rather have a slim case than maximum run time. Skip it if you take a lot of calls in loud places or you hate charging routines.
The HTT-21 leads with its microphone system. The spec sheet calls out ENC — Environmental Noise Cancellation — with four mics, and the brand is careful to explain the distinction: ENC works on the sound picked up by the mics so the person on the other end hears your voice instead of the café, the street or the train carriage. That's a different job from ANC, and it's the single most useful feature here if you live on calls.
The other headline is the driver. A 13 mm dynamic driver is large for an in-ear bud, and it's paired with a 20 Hz – 20,000 Hz frequency range and 98 dB sensitivity — the recipe for the "deep bass" the listing promises. Bluetooth 5.4 is the newer standard of the two, and latency is quoted at 45 ms, which is low enough that lip-sync on video and casual gaming shouldn't feel off. A voice assistant button rounds out the controls, with Siri and Google Assistant both named.
Battery is the strong suit. The HTT-21 lists up to 6 hours per charge and roughly 40 hours with the case, and the fast-charge claim — 10 minutes for about 100 minutes of playback — is genuinely handy when you're heading out the door. The case is a 500 mAh unit that takes about 1.5 hours to charge. IPX5 gives slightly better water protection than IPX4, though neither is meant for swimming. Note the total weight: 36.6 g for the buds, with the case adding 28.7 g. The box includes three rubber ear tips in S/M/L and a USB-C cord.
Buy it if you take calls on the move, want deeper bass, or want to top up in minutes. Skip it if you want the smallest possible case or you never use a microphone.
• Best for clear voice calls → HARMONY TWENTY-TWO HTT-21. Four mics with ENC beat a single ENC mic setup on paper for call clarity in noisy places.
• Best for battery life → HARMONY TWENTY-TWO HTT-21. About 6 hours per charge and roughly 40 hours total, versus about 5 hours and 17 hours for the Motorola.
• Best for fast top-ups → HARMONY TWENTY-TWO HTT-21. 10 minutes of charging for about 100 minutes of playback is a spec the Motorola pair doesn't match; its case takes about 2 hours to fill.
• Best for lightweight, pocket-friendly carry → Motorola Sound Buds 065. About 60 g total and a slim, simple design.
• Best for water and sweat protection → HARMONY TWENTY-TWO HTT-21 on paper. IPX5 edges out IPX4, though both handle sweat and light rain.
• Best for bass depth → HARMONY TWENTY-TWO HTT-21. A 13 mm driver against the Motorola's unspecified dynamic driver.
• Best for hands-free assistant use → Motorola Sound Buds 065. Google Assistant is built into the controls, whereas the HTT-21 relies on a button press or Siri/Google Assistant activation.
• Best for connectivity longevity → HARMONY TWENTY-TWO HTT-21. Bluetooth 5.4 is a newer generation than the Motorola's Bluetooth 5.0/5.3 listing, with lower stated latency.
If I were choosing for myself, I'd take the HARMONY TWENTY-TWO HTT-21. In my opinion, the combination of a four-mic ENC system, a 13 mm bass driver, Bluetooth 5.4 and fast charging covers more of what most people actually do with earbuds — take calls, listen on the move and never think too hard about charging. The Motorola Sound Buds 065 is the better pick only if a featherweight fit and a slim case matter more to you than call clarity and run time. If price is the deciding factor for you, check the current price on Amazon for both before you commit.
FAQ
how to use wireless headphones mic on pc
how to use mic on wireless headphones
The microphone is built into the earbuds, so there's nothing extra to plug in. Just connect over Bluetooth and answer calls with the touch controls — both the Moto Buds 065 and the HTT-21 list touch controls and ENC call handling.
can you use bluetooth headphones as a mic
Yes. Any Bluetooth earbuds with a built-in mic, like both of these, can act as a microphone for calls, video meetings and voice chat once paired. Call quality depends on the mic array — the HTT-21's four-mic ENC setup is the more call-focused design of the two.
do all bluetooth headphones have a microphone
No. Bluetooth headphones commonly include a mic for calls, but it isn't guaranteed by the standard. Both products here do list ENC microphones, so both can be used for voice.
