If you want serious, upgradeable in-ear monitors for stage, studio or critical listening, choose BASN Bmaster; if you need a big bulk pack of simple wired earbuds for a classroom, library or shared-device program, choose Kigeli 100.
• BASN Bmaster's biggest strength: a hybrid triple-driver setup (two 10 mm dynamic drivers plus one balanced armature) with detachable MMCX cables, so the sound and the wiring are both upgradeable.
• BASN Bmaster's biggest trade-off: it's one pair of specialist IEMs with a cable that routes over the ear, which is more fuss than a plug-and-go earbud.
• Kigeli 100's biggest strength: it's a bulk set of 100 wired in-ear earbuds, which makes it a practical consumable rather than a single prized pair.
• Kigeli 100's biggest trade-off: no microphone and no volume adjustment, so it's playback-only — you can't take calls or control your music from the cable.
• Buy BASN Bmaster if you're a musician, drummer, sound engineer or detail-focused listener who wants one serious pair.
• Buy Kigeli 100 if you're equipping a class, a library, a gym or a drawer full of spare earbuds for kids and guests.
The Bmaster is built around its driver design. Inside each earpiece there are two 10 mm dynamic drivers paired with a single balanced armature, a hybrid arrangement that BASN uses to push bass weight from the dynamic side and articulation from the armature side. The stated frequency range runs from 18 Hz to 22 kHz, and impedance sits at a low 18 ohm, which means these are easy to drive from a phone or a laptop without reaching for an amp. In my reading of the spec sheet, that combination is the whole point of the product: it's tuned for people who want to hear detail in a mix rather than just background music.
The second thing that stands out is the fit philosophy. The earpieces sit at a 45-degree angle into the ear canal, and the cable is designed to hook over the back of the ear, reinforced with memory wire you can bend to the shape of your ear. That over-ear routing does two jobs: it keeps the cable out of the way of your hands and instrument, and it holds the earpiece steady so it won't drop out mid-performance. BASN explicitly points this design at stage performance, studio recording and church use — situations where a loose earbud is a real problem. If you've ever had a bud pop out during a take, you know exactly why that matters.
The cable situation is unusually flexible. You get two detachable MMCX cables in the box: a silver-plated oxygen-free copper cable, and a second woven cable with an inline mic and remote for calls and voice commands. MMCX is a standard connector, so you can swap in other MMCX cables later if you want a different length or a different feel. Around that, the package includes 12 pairs of eartips in different sizes, a 1/4-inch adapter for plugging into a monitoring system or interface, a shirt clip and a cleaning brush, plus a carrying case. It's a kit, not just a pair of buds.
So who should buy it? Musicians, drummers, worship-team players, podcasters and anyone who wants one pair of wired IEMs they can rely on and maintain. Who should skip it? Anyone who just needs cheap spares to hand out, and anyone who refuses to deal with over-ear cable routing or tip swapping. If that's you, the Kigeli set is the more sensible buy.
The Kigeli 100 is a different category of product entirely, and it's honest about that. This is a bulk box of 100 wired in-ear earbuds in black and grey, with a dynamic driver in each earpiece, a 3.5 mm jack and roughly one metre of cable. The shells are ABS plastic, chosen for a shiny finish that resists everyday scratches and scuffs — which is exactly the right priority when the same pair is going to be used by dozens of different people.
The feature list is deliberately simple. Kigeli describes stereo surround sound with noticeable bass and a straightforward, sensitive response, and the earpiece shape follows the geometry of the ear so it sits in place without hurting. There's sound isolation, which helps in a noisy room. What there isn't: a microphone, and any volume adjustment. The cable is playback only. That's a meaningful limitation if you plan to use these for online classes with two-way audio or for calls — they simply aren't built for that.
Where the Kigeli 100 makes sense is volume and turnover. Schools, libraries, museums, gyms and testing rooms all go through earbuds at a rate that makes single premium pairs impractical. Handing out a sealed pair, using it, and moving on is the workflow this product is designed for. The 3.5 mm jack fits most phones, tablets, laptops, desktops and MP3 players, though Kigeli does advise checking your devices match before ordering — sensible advice, since a growing number of phones have dropped the headphone jack entirely. Kigeli also notes a winding hazard and says adult supervision is needed for children under three.
Buy the Kigeli 100 if you're responsible for equipping a group, if you lose or break earbuds constantly, or if you want a shared pool for guests and students. Skip it if you care about sound quality as a hobby, if you need a mic for calls, or if you want to swap cables and tune the fit.
• Best for critical listening and monitoring → BASN Bmaster. Hybrid triple-driver design, 18 Hz–22 kHz range, 18 ohm impedance.
• Best for equipping a group → Kigeli 100. A bulk set of 100 pairs, which is the entire premise of the product.
• Best for taking calls → BASN Bmaster. One of its two included MMCX cables has a built-in mic and remote; the Kigeli 100 has no microphone at all.
• Best for fit security during performance → BASN Bmaster. The 45-degree angled nozzles and reinforced over-ear memory wire are designed to stop the buds falling out.
• Best for low-maintenance, low-stakes use → Kigeli 100. ABS shells built to shrug off daily scratches, and no cable to route or replace.
• Best for replaceable parts → BASN Bmaster. Detachable MMCX cables, 12 pairs of eartips, a cleaning brush and a carrying case.
• Best for kids and shared devices → Kigeli 100, with the caveat that there's no volume control on the cable and adult supervision is advised for very young children.
• Best for plug-and-play simplicity → Kigeli 100. No tip rolling, no over-ear routing, no decisions.
In my opinion, the BASN Bmaster is the one I'd buy for myself. The triple-driver hybrid design, the low 18 ohm impedance, the two detachable MMCX cables and the 12 pairs of eartips give you a product you can tune, maintain and keep using — and the over-ear fit is genuinely purposeful for stage and studio work. The Kigeli 100 isn't competing on sound; it's competing on logistics, and for a classroom or a shared equipment cupboard it's the smarter purchase by a wide margin. Pick based on whether you're buying one pair for yourself or a hundred pairs for other people.
what is in ear earphones
In-ear earphones are wired or wireless buds that sit inside the ear canal rather than resting on the outer ear. Both products here are that type: the BASN Bmaster uses angled nozzles with swappable eartips, while the Kigeli 100 uses a simpler rounded in-ear shell with a fixed tip.
what is in ear monitor earphones
An in-ear monitor is a wired earbud designed for performers and engineers to hear a mix accurately on stage or in a studio. The BASN Bmaster fits that description directly — hybrid triple drivers, over-ear cable routing, detachable MMCX connectors and a 1/4-inch adapter for monitoring systems. The Kigeli 100 is a general-purpose listening earbud, not a monitor.
how to clean earphones ear wax
Wipe the eartips with a dry cloth or a little isopropyl alcohol, and never push anything into the nozzle. The BASN Bmaster ships with a cleaning brush and removable eartips you can take off and wash, which makes this much easier. The Kigeli 100 has fixed tips, so you're limited to wiping the outside.
how to ear earphones
Seat the bud so it seals gently in the canal — a good seal is what gives you bass and noise isolation. With the BASN Bmaster, bend the memory wire over the back of your ear and try different eartip sizes from the 12 included pairs until the fit feels secure. The Kigeli 100 just pushes straight in.
