How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the safer long-term bet on battery, water protection and support, choose Csasan Earbuds; if you need the newer Bluetooth generation, more microphones for calls and a slightly bigger driver, choose BUABMEQ Earbuds 2025.
• Csasan Earbuds — biggest strength: 40 hours of total playtime from a case that shows its charge as a number, plus a 24-month repairment warranty and IPX7 protection — a very complete everyday package.
• Csasan Earbuds — biggest trade-off: Bluetooth 5.3 rather than 5.4, and 13mm drivers versus the larger 14.2mm set in the rival, so it is not the newest spec sheet on paper.
• BUABMEQ Earbuds 2025 — biggest strength: Bluetooth 5.4, a 14.2mm driver and a four-microphone ENC array — the most interesting mix here for call quality and wireless stability.
• BUABMEQ Earbuds 2025 — biggest trade-off: A shorter 90-day warranty and 48 hours of total playtime that depends on rotating the buds, since each single charge is rated at 6–8 hours.
• Who each pick is for: Csasan for anyone who wants set-and-forget battery life and long-term peace of mind; BUABMEQ for buyers who prioritise the newest Bluetooth version and clearer voice pickup.
The Csasan Earbuds (model J90 Pro) are built around one idea: keep going without thinking about the charger. Each bud is rated for up to 8 hours of listening, and the case adds another four to five full charges for a total of 40 hours. The case itself has a numerical LED readout for its own charge level and light bars for each bud, so you always know where you stand. Charging from empty takes about 1.5 hours over USB-C.
The other half of the story is calls. Each bud carries two microphones — four in total — using ENC call noise cancellation to pull your voice out of background noise, which is exactly what you want on a windy street or in a busy office. The 13mm dynamic driver covers 20Hz–20kHz and is tuned for deep bass, so music has weight without sounding thin. Bluetooth 5.3 with a hall switch means the buds reconnect automatically the moment you open the case, and the stated wireless range reaches up to 15 metres.
Who should skip it: buyers who specifically want Bluetooth 5.4, the largest driver available, or a four-mic array. If those specs top your list, read on.
BUABMEQ Earbuds 2025: Who It's For
The BUABMEQ S40 leads with connectivity. Bluetooth 5.4 is the newest version here, and combined with a hall switch it reconnects automatically when you open the case, just like the Csasan. The difference is the extra headroom 5.4 can offer for stability and latency on newer phones and laptops — worth noting if you upgrade your devices often.
Call handling is the second pillar. Each bud has a built-in microphone — four in total across the pair — with CVC noise cancelling, the processing that helps the person on the other end hear you clearly rather than the room around you. If you spend your day on calls, that is a meaningful feature to weigh.
Sound comes from a 14.2mm dynamic driver with triple-layer composite diaphragms, covering the same 20Hz–20kHz range but with a larger piston area than the Csasan's 13mm unit. In practice that usually means more low-end presence and a wider sense of space. You also get mono mode and twin stereo mode, so you can hand one bud to a friend and share audio — a small but genuinely useful touch.
Battery is rated at 7 hours average per bud and 6–8 hours on a single charge, with a 400mAh case that provides four extra full charges for a total of 48 hours when you rotate the buds. The dual digital LED display shows the case level and flashes from 1 to 100 while charging. Each bud weighs 0.13oz and measures 1.33 x 0.66in, with the case at 2.04 x 0.98in — compact enough for a pocket. Three ear tip sizes are included, and IPX7 waterproofing with a nano-coating covers sweat and rain.
Who should skip it: anyone who wants the longest warranty or the simplest battery maths. The 90-day warranty is short, and the 48-hour figure assumes you swap buds in and out rather than running one pair continuously.
• Best for total battery life → Csasan Earbuds. 40 hours with a numerical case display and up to 8 hours per single charge is easier to live with than a 48-hour figure that relies on rotating buds.
• Best for the newest wireless standard → BUABMEQ Earbuds 2025. Bluetooth 5.4 versus 5.3 is the single clearest spec gap between them.
• Best for call clarity on paper → BUABMEQ Earbuds 2025. Four ENC microphones with CVC noise cancelling is a stronger call-focused setup than the Csasan's ENC array.
• Best for bass and driver size → BUABMEQ Earbuds 2025. A 14.2mm driver with triple-layer diaphragms beats a 13mm unit for sheer air movement.
• Best for long-term peace of mind → Csasan Earbuds. A 24-month repairment warranty against 90 days is not a close contest.
• Best for sharing audio → BUABMEQ Earbuds 2025. Mono mode lets one bud work alone, so you can pass the other to someone else.
• Best for travel and workouts → either. Both are IPX7, both are lightweight, both use touch controls and USB-C charging.
• Best for set-and-forget simplicity → Csasan Earbuds. The numbered case display removes all guesswork about remaining power.
I would buy the Csasan Earbuds. The reason is not the spec sheet — on paper the BUABMEQ wins on Bluetooth version, driver size and microphone count, and those are real advantages. But the Csasan pairs 40 hours of usable battery, a clear numeric charge display, IPX7 protection and a 24-month repairment warranty into one package. For most people, that combination of reliability and support matters more day to day than a 0.4 Bluetooth version bump. If calls and audio quality are your top priority, the BUABMEQ is the better fit — just go in knowing the warranty is shorter.
FAQ
how to use wireless headphones mic on pc
how to use mic on wireless headphones
Just wear the buds and take the call — the microphones are built in. On these models the touch controls handle answering and ending calls, so you never touch your phone. ENC or CVC processing then works to reduce background noise so your voice comes through clearly.
can you use bluetooth headphones as a mic
Yes. Any Bluetooth headset with a built-in microphone, including both earbuds here, can act as a microphone for calls, video meetings and voice chat. The earbuds simply need to be selected as the input device in your app or system settings.
do all bluetooth headphones have a microphone
No. Plenty of Bluetooth headphones are designed for listening only. That is why it pays to check the listing — both the Csasan Earbuds and the BUABMEQ Earbuds 2025 explicitly include built-in microphones for calls, with noise-cancelling processing on top.
