• 2B2C Open-Ear biggest strength: an open-ear hook design with active noise cancellation on the mic side, so you hear your calls and your surroundings at the same time.
• 2B2C Open-Ear biggest trade-off: 10 hours of battery life per charge and no charging case figure listed, so heavy all-day users will be reaching for the cable.
• sprtoybat Earbuds biggest strength: up to 68 hours of total playtime with an 800 mAh charging case, plus IPX7 waterproofing and Bluetooth 5.4.
• sprtoybat Earbuds biggest trade-off: they sit in your ear canal, so you lose the open-ear awareness that makes the 2B2C set so easy to live with.
• Who 2B2C Open-Ear is for: drivers, truckers, office workers and anyone who takes a lot of calls while moving through the real world.
• Who sprtoybat Earbuds is for: runners, cyclists and gym-goers who want long battery life and a fit that survives sweat and motion.
The 2B2C Open-Ear is built around a single idea: keep your ears open. The earpiece is an open-ear hook that rests outside the ear canal rather than plugging it, so audio comes to you while ambient sound still gets in. If you have ever pulled an earbud out at a red light or missed someone calling your name in a warehouse, that design choice is the whole point. It weighs 1.2 ounces, and the lightweight build combined with the hook shape is meant for extended wear — the kind of session that stretches across a full shift rather than a 45-minute workout.
On the call side, the integrated microphone is the headline feature. The spec sheet lists active noise cancellation, which in this form factor is aimed at the mic and call clarity rather than sealing you off from the world. Controls are generous: button control plus touch plus voice, with a multifunction button handling the everyday stuff. Bluetooth 5.3, a 33-foot range, a 2-hour charge time and 10 hours of average battery life round out the practical picture. The supported protocol list is long — HSP, HFP, AVRCP, A2DP, SBC, AAC and the aptX family — which matters if you care about codec compatibility across phones and laptops.
sprtoybat Earbuds: Who It's For
The sprtoybat Earbuds go the other direction entirely. These are in-ear sport earphones with a hook, TPU ear hooks and three sizes of soft tips (S/M/L) so you can dial in a fit that stays put. The spec sheet lists IPX7 waterproof protection, which is the rating you want for sweat, rain and the general mess of outdoor training. If you run, cycle, lift or spend a lot of time moving, the secure-hook approach is a much better match than anything that rests loosely on your ear.
Battery is where these pull away. You get up to 8 hours on a single charge, and the charging case can refill the buds roughly 8 to 9 times for up to 68 hours of total playtime. The case carries an 800 mAh battery and an LED display that shows remaining charge, which is one of those small features you appreciate more the longer you own the product. Fast charging over Type-C gets you about 2 hours of music from a 10-minute top-up. Bluetooth 5.4 is the newest version in this comparison, with a 15-meter range, and the earphones pair with iOS, Android, laptops and tablets.
The 14.2mm dual-layer graphene drivers are the audio story, and the built-in ENC microphone is the call story — the spec sheet describes it as reducing background noise for clearer calls in noisy environments. One detail worth flagging: the product information lists passive noise cancellation, while the marketing copy talks about ENC on the mic. Those are two different things, and the passive entry is the more literal description of what the earbuds do to the sound around you. Controls are touch-based, though the description also mentions physical buttons as an accidental-press safeguard — worth confirming against the listing if button feel matters to you.
Who should buy it? Runners, gym regulars, commuters and anyone who wants to charge once and forget about it for days. Who should skip it? If you need to hear traffic, a forklift or a colleague walking up behind you, an in-ear seal works against you. And if you dislike the plugged-in feeling, the open-ear 2B2C is the better fit.
• Best for situational awareness → 2B2C Open-Ear. The open-ear hook rests outside the canal by design.
• Best for battery life → sprtoybat Earbuds. Up to 68 hours total with the charging case versus 10 hours on the 2B2C.
• Best for calls in motion → 2B2C Open-Ear. Active noise cancellation, a multifunction button and a long protocol list built around headset use.
• Best for workouts and sweat → sprtoybat Earbuds. IPX7 waterproofing plus three tip sizes and flexible ear hooks.
• Best for newer Bluetooth → sprtoybat Earbuds. Bluetooth 5.4 versus 5.3, with a 15-meter range.
• Best for drivers → 2B2C Open-Ear. Nothing blocks your ears while the mic stays live.
• Best for multi-day travel → sprtoybat Earbuds. The case and LED charge display make it a charge-and-go pick.
• Best for lighter wear over long stretches → 2B2C Open-Ear. At 1.2 ounces with an open hook, there is no seal pressing on your canal.
In my opinion, the honest answer splits by lifestyle. If your day is calls, driving and staying aware of your surroundings, I would buy the 2B2C Open-Ear — the open-ear design, active noise cancellation and headset-focused controls are exactly what that job needs, and 10 hours per charge is workable if you charge nightly. If your priority is training, sweat resistance and battery that lasts days, I would buy the sprtoybat Earbuds instead; IPX7, 68 hours with the case and Bluetooth 5.4 are hard to argue with for sport use. Neither is universally better — they solve different problems. Check the current price on Amazon before you commit, since that is the one variable this comparison cannot cover.
how to use wireless headphones mic on pc
Pair the headphones over Bluetooth, then open your computer's sound settings and select the headset as both the output and input device. On the 2B2C Open-Ear, the built-in mic and multifunction button handle calls once paired; on the sprtoybat Earbuds, the ENC mic takes over. If the mic does not appear, remove and re-pair the device so both the audio and headset profiles load.
how to use mic on wireless headphones
Connect over Bluetooth, then confirm the input source is set to the headset rather than your laptop's built-in mic. Both products here support hands-free calling — the 2B2C has a multifunction button, and the sprtoybat uses touch controls. The supported protocols on the 2B2C (HFP and HSP) are the ones that carry voice, which is why those profiles matter.
can you use bluetooth headphones as a mic
Yes. Any Bluetooth headset with a built-in microphone can work as a mic input once the hands-free profile is active on your device. Both the 2B2C Open-Ear and the sprtoybat Earbuds list built-in microphones and call support. Just remember that call audio and music audio use different profiles, so quality can change when the mic engages.
do all bluetooth headphones have a microphone
No. Bluetooth headphones without a built-in mic exist, and they can only play audio. Both products compared here do include microphones — the 2B2C lists an integrated mic with active noise cancellation, and the sprtoybat lists an ENC mic for calls. If calling is a priority, confirm the mic is listed before buying.
