How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the longer per-charge runtime and a semi-in-ear fit that stays light for all-day wear, choose Motast Earbud; if you need faster recharging, a sealed in-ear fit with swappable eartips, and a longer Bluetooth range for a wireless headset for pc, choose BLXSounds Earbuds. Both are budget Bluetooth 5.3 earbuds with four ENC mics and a 40-hour total figure, which is why so many people hunting for the best earphones for pc end up stuck between them. The real differences are in battery math, fit style, and how the mics behave on calls.
• Motast Earbud — biggest strength: 14.2mm dynamic drivers plus a semi-in-ear design at 0.14 oz per bud, with IP7 waterproofing, a 40-hour total figure and dual LED power displays.
• Motast Earbud — biggest trade-off: Roughly 6 hours per charge at 50–60% volume, and a 6-hour charge time in the spec sheet, so you lean heavily on the case.
• BLXSounds Earbuds — biggest strength: 8 hours per charge, a 1-hour charge time, a 15-meter Bluetooth range, and three sizes of silicone eartips for a sealed in-ear fit.
• BLXSounds Earbuds — biggest trade-off: IP5 water resistance only, so heavy sweat or rain is riskier than on the Motast pair.
• Who each pick is for: Motast Earbud for long-session listeners who want a light, open, semi-in-ear feel and strong splash protection; BLXSounds Earbuds for call-heavy users and PC workers who want a sealed fit, quick top-ups and extra wireless range.
The Motast Earbud (model T19) is built around two ideas: a big driver and a light, open fit. The 14.2mm dynamic speakers are larger than what you'll find in most earbuds at this level, and a bigger driver generally moves more air, which is why the spec sheet talks about a wider frequency range and more detailed sound. Paired with the stereo bass tuning, that's a recipe for a warmer, fuller low end rather than a thin, clinical presentation. Four ENC mics handle calls, and the listed figure is passive cancellation of up to 80% of background noise. Treat that as the manufacturer's number, not a lab measurement, but it tells you the design intent: keep your voice ahead of the room.
The fit is semi-in-ear, and each earbud is 0.14 oz — light enough that you'll forget you're wearing them. That open style is more comfortable for long stretches and lets in ambient sound, which some people prefer at a desk or on a bike. The catch is that semi-in-ear doesn't seal, so isolation is modest and bass can feel less anchored than a sealed in-ear design. IP7 nano-coating is the standout spec: that's a high water-resistance rating for earbuds, and it's the reason I'd point sweaty runners and rainy-commute riders here.
Buy it if: you want the lightest-feeling option, the biggest driver, the best water resistance, and you're fine charging overnight. Skip it if: you need a sealed fit with tip options, fast recharging, or maximum Bluetooth range.
BLXSounds Earbuds: Who It's For
The BLXSounds Earbuds (A9 Pro) read like a pair designed for the desk and the phone call. The 13.2mm dynamic drivers use triple-layer composite diaphragms with what the sheet calls professional tuning, and the sound is described as powerful bass with a clear, balanced top end. A 32-ohm impedance figure is listed, which is a normal, easy-to-drive load — nothing here suggests you'd need special gear to get volume out of them. On the mic side, the four ENC mics are tuned to reduce moderate wind noise specifically, which matters if you take calls outdoors or near a window.
Battery is the clearest win. Eight hours per charge, 40 hours total with the case, and a 1-hour charge time. That last number is the one I keep coming back to: an hour on the cable gets you a full day of listening, versus the overnight cycle on the Motast pair. The LED display shows charge levels for each earbud and the case separately, same practical benefit as the Motast design. Bluetooth 5.3 gives automatic pairing and a listed range of up to 15 meters, which is noticeably longer than typical earbud range and useful if you walk away from your laptop mid-call.
Comfort comes from a sealed in-ear design with three sizes of soft silicone eartips, and each bud weighs 4 g — the same as the Motast pair. Sealed tips mean better passive isolation and more consistent bass, plus you can size them to your ears. The compromise is water resistance: IP5 covers dust and rain, which is fine for commuting and light workouts, but it's a lower rating than IP7 and I wouldn't push it through heavy sweat sessions. The active noise cancellation listing in the product data is worth noting as a spec field; the feature bullets emphasize ENC call noise reduction, so I'd treat call clarity as the headline rather than assume strong ANC for music.
Side-by-Side: Which Should You Choose?
• Best for all-day battery per charge → BLXSounds Earbuds (8 hours vs about 6 hours).
• Best for fast top-ups → BLXSounds Earbuds (1-hour charge time vs 6 hours).
• Best for sweat and rain → Motast Earbud (IP7 nano-coating vs IP5).
• Best for a sealed, customizable fit → BLXSounds Earbuds (three silicone eartip sizes vs a fixed semi-in-ear shape).
• Best for a light, open, barely-there feel → Motast Earbud (semi-in-ear, 0.14 oz per bud).
• Best for bigger drivers and bass weight → Motast Earbud (14.2mm vs 13.2mm).
• Best for range and roaming from your desk → BLXSounds Earbuds (listed up to 15 m).
• Best for wind-heavy calls → BLXSounds Earbuds (ENC mics tuned for moderate wind noise).
For a headphone for pc setup where you're on calls, jumping between apps, and topping up between meetings, I'd buy the BLXSounds Earbuds. The 1-hour charge time, 8-hour single-charge runtime, 15-meter range and sealed fit with eartip options make it the easier pair to live with at a desk all day, and the wind-noise-focused ENC mics suit a wireless headset for pc used for voice chat.
That said, if your priority is long listening sessions in a light, open-fitting bud and you want the best water resistance of the two, the Motast Earbud is the one I'd recommend — just plan on charging it overnight and check the current price on Amazon before you commit.
FAQ
Pair the earbuds over Bluetooth 5.3, then open your computer's sound settings and select the earbuds as both the output and the input device. Both the Motast Earbud and BLXSounds Earbuds support laptops and Bluetooth-enabled devices, and both use built-in ENC mics for calls.
how to use mic on wireless headphones
Just wear them and take the call — the mics are built in and there's no boom arm to position. Touch controls on both models handle answering and ending calls, so you don't need to touch your phone or laptop.
can you use bluetooth headphones as a mic
Yes. Both of these are Bluetooth earbuds with four built-in ENC mics, so they work as a microphone for calls and voice chat once paired. The BLXSounds pair is specifically tuned to reduce moderate wind noise, which helps outdoors.
do all bluetooth headphones have a microphone
No. Plenty of Bluetooth headphones are listen-only. Both models here do have mics — the Motast Earbud lists four ENC mics with up to 80% passive background-noise cancellation, and the BLXSounds Earbuds list four ENC noise-cancelling mics.
