How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the newer Bluetooth version, a longer wireless range and bigger drivers for richer bass, choose Jesebang Earbuds; if you need earhooks tuned for smaller ears and glasses wearers, choose Csasan Sports Earbuds. Both are over-ear-hook sports buds with ENC mics, 48-hour total battery and IP7-class water protection. The difference is in the details — and those details decide which one fits your head and your routine.
• Jesebang Earbuds — biggest strength: Bluetooth 5.4 with a 15 m range, 14.2 mm dynamic drivers and four ENC mics that the spec sheet says filter more than 80% of outside noise.
• Jesebang Earbuds — biggest trade-off: It's the bulkier-feeling proposition of the two on paper — a silicone over-ear hook plus an in-ear tip, and no explicit accommodation for glasses wearers.
• Csasan Sports Earbuds — biggest strength: Earhook ergonomics built around pressure distribution, explicitly aimed at smaller ear canals and people who wear glasses, plus IPX7 protection.
• Csasan Sports Earbuds — biggest trade-off: Bluetooth 5.3, a 10 m range and 13 mm drivers — slightly behind Jesebang on paper, and the protection is not meant for swimming.
• Who each is for: Jesebang for the buyer who wants the newest connection standard, the widest range and the deepest low end. Csasan for the buyer whose main worry is the buds staying comfortable and locked in during long, sweaty sessions.
The Jesebang YT18 is a sports earbud built around three ideas: connection, calls and bass. The Bluetooth 5.4 radio is the headline — the spec sheet claims a 30% bump in transmission speed over the previous generation, a stable signal, and a working range up to 15 m. In practice that means you can leave your phone on a bench, a gym bag or a kitchen counter and keep listening while you move around. Hall-effect sensing handles the pairing ritual: after the first setup, opening the case and lifting the buds out reconnects them automatically, no button-holding.
Call quality is the second pillar. Jesebang uses four ENC microphones that the listing says cut more than 80% of external noise, which is the kind of claim that matters most on a windy running path or a busy commute. The 14.2 mm dynamic drivers are the largest in this comparison, and the sound chamber design is aimed squarely at low-frequency depth with balanced mids and clear highs. If your playlist leans on bass-heavy training music, that's the spec to care about.
Comfort and control are handled with a soft, flexible earhook and a 6-gram-per-bud weight, with three ear-tip sizes (S, M, L) so you can dial in the seal. Battery is 8 hours per charge and up to 48 hours with the 400 mAh case, which itself recharges in about 2 hours. A dual LED display shows the remaining power for the buds and the case. IP7 nano-coating covers sweat and rain. Touch controls handle play/pause, volume, tracks, calls and your voice assistant, and it works with iOS, Android and standard Bluetooth devices.
Csasan Sports Earbuds: Who It's For
The Csasan V90 takes a different starting point: fit first, sound second. The flexible silicone earhooks are described as adapting to your individual ear contour, with a pressure-distributing design that specifically targets two groups — people with smaller ear canals and people who wear glasses. That's a genuinely useful piece of positioning, because wear fatigue and hook-versus-glasses conflict are the two most common reasons people abandon sport buds mid-run. The claim here is that they stay locked in without mid-workout fiddling, whether you're on a cycling trail or grinding out a long run.
Sound comes from 13 mm dynamic drivers — a step down from Jesebang's 14.2 mm, but still a proper dynamic driver with a 20 Hz–20 kHz range and a bass-forward tuning meant to drive training momentum. The ENC mic system isolates your voice and pushes down background noise like gym music or street traffic, so calls and virtual meetings stay usable without stopping what you're doing.
Battery mirrors Jesebang closely: 8 hours per charge, 1.5-hour USB-C fast charge, and a 48-hour total with the case. The dual LED display shows the exact battery percentage for the case and each bud individually. Bluetooth 5.3 handles the connection with low latency and a 10 m range, and a Hall sensor auto-pairs the moment you open the case, with device switching between phone, tablet and laptop. IPX7 protection handles sweat, rain and humidity — but the listing is clear that this is not for swimming or prolonged submersion, so don't treat it as pool gear. Touch panels cover music, volume, calls, track skipping and voice assistants across iOS, Android and most Bluetooth devices.
Who should buy it: anyone with smaller ears, glasses wearers, and athletes who prioritize a fatigue-free locked-in fit over raw spec numbers. Who should skip it: buyers who want the newest Bluetooth generation, the longest range or the biggest driver — Jesebang wins all three on paper.
Side-by-Side: Which Should You Choose?
• Best Bluetooth version and range → Jesebang Earbuds (5.4, up to 15 m versus 5.3 and 10 m).
• Biggest drivers and deepest bass → Jesebang Earbuds (14.2 mm versus 13 mm).
• Best call clarity in noisy places → Jesebang Earbuds — four ENC mics with the stated 80%+ external noise filtering.
• Best fit-focused ergonomics for long sessions → Csasan Sports Earbuds, thanks to the pressure-distributing hook design.
• Battery life → a tie. Both deliver 8 hours per charge, 48 hours total and a 1.5-hour charge time.
• Water protection → effectively a tie, with one caveat: Csasan states IPX7 explicitly but warns against swimming; Jesebang states IP7 nano-coating for sweat and rain.
• Battery visibility → both, since each has a dual LED display for case and bud power.
In my opinion, Jesebang Earbuds are the better all-round pick for most people. Bluetooth 5.4, the 15 m range, four ENC mics and the larger 14.2 mm drivers give you more headroom on connection, calls and bass, and the 48-hour battery and IP7 coating cover the sports basics without compromise. I'd only steer you to Csasan Sports Earbuds if fit is your deciding factor — smaller ears or glasses make its earhook design the smarter choice, and a bud that stays comfortable is worth more than a spec-sheet edge you'll never notice. Check the current price on Amazon before you commit, since that's the one variable that can flip this decision.
how to use wireless headphones mic on pc
Pair the buds over Bluetooth, then open your computer's sound settings and set the headset as both the output and the input device. On Windows, pick the "Headset" profile rather than "Headphones" so the mic channel is active; on macOS, select the buds under Input in Sound settings. Both Jesebang and Csasan use ENC mics and support standard Bluetooth devices, so no extra dongle is needed.
how to use mic on wireless headphones
Put the buds in, connect them to your phone or laptop, then start your call or recording app and confirm the earbuds are selected as the microphone. The touch panels on both models handle answer and hang-up, and the ENC system actively filters background noise. If the mic seems quiet, check that you're using the headset profile and that the buds aren't in a single-ear mode.
can you use bluetooth headphones as a mic
Yes — any Bluetooth headset with a built-in microphone can work as a mic, and both of these have ENC mic systems for calls. The catch is that using the mic usually switches the connection to a lower-bandwidth headset profile, which slightly reduces audio quality. For calls and meetings that trade-off is normal and not noticeable in practice.
do all bluetooth headphones have a microphone
No. Plenty of Bluetooth headphones are playback-only and have no mic at all, which is why the spec sheet matters. Both the Jesebang YT18 and the Csasan V90 list ENC microphones for calls, so both can be used for voice — but always confirm the mic spec before buying any wireless bud.
