If you want a stage-ready personal in-ear monitor amplifier you can run off a wall outlet with two sources mixed into one clean feed, choose ANLEON S1; if you need actual in-ear monitor earphones that seal out the stage and plug straight into your existing gear, choose BASN Bsinger BC100.
• ANLEON S1 – biggest strength: Dual XLR inputs with Level and Balance/Mix controls let you blend two sources into one personal monitor feed, and the high-power headphone output with a limiter is built to stay audible over a loud band.
• ANLEON S1 – biggest trade-off: It's a corded desktop/stage unit, not earphones. You still need your own in-ears, and it's aimed at performers who stay put rather than move around the stage.
• BASN Bsinger BC100 – biggest strength: Ergonomic in-ear design with memory earhooks, roughly 20dB of noise isolation, and a detachable MMCX cable you can swap or upgrade.
• BASN Bsinger BC100 – biggest trade-off: It's a passive IEM — no amplifier, no mixing — and the 3.5mm jack means you may need an adapter for pro monitoring systems with 1/4" outputs.
• Who each pick is for: ANLEON S1 for drummers, keyboardists and other mostly-stationary players who need to mix two sources; BASN Bsinger BC100 for singers, drummers and musicians who want a secure, isolating in-ear they can wear for a whole set.
The ANLEON S1 is a personal in-ear monitor headphone amplifier — think of it as the little box that sits next to you and feeds your in-ears. It takes dual XLR inputs, so you can run two sources in at once, and switch between 2-channel, mono or stereo operation. Two knobs, Level and Balance, do the mixing. That's the whole idea: no menu diving, no app, just reach over and dial in your blend.
What it does best is solve the "I can't hear myself" problem. The headphone output is high-powered on purpose, and there's a limiter to protect your ears at the same time. The spec sheet explicitly calls it loud enough for drummers, which tells you who the designers had in mind: the person at the back of the stage getting buried under guitars. The aluminum enclosure and black finish suggest something meant to survive a pedalboard or a floor tom's worth of abuse. Power comes from a corded 9V/300mA adapter (110–240V), and the box ships with the amp, a user manual and the adaptor. It's a solid-state amp, so no tubes to worry about, and ANLEON backs it with a 36-month warranty.
Who should skip it: anyone who moves around the stage — the description is upfront that it suits musicians who aren't moving. And if you don't already own in-ear monitors, this isn't the earphones, it's the amplifier. Budget for both.
BASN Bsinger BC100: Who It's For
The BASN Bsinger BC100 is the other half of that equation: the earphones themselves. It's a universal-fit in-ear monitor built around a dual dynamic micro driver with a PET and copper diaphragm, covering 20Hz to 20,000Hz at 18 ohms impedance. Low impedance like that means it doesn't demand much power to get loud, which is handy when you're plugging into a phone, a tablet or a performing device.
The real story here is fit and isolation. BASN studied ear canals to shape a universal earpiece that behaves more like a custom mold, and the adjustable memory earhook bends to your ear and holds. That's what keeps the seal — and the seal is what gives you the claimed up to 20dB of noise blocking. On a loud stage, that isolation is the difference between hearing your own voice and guessing at it. The soft silicone tips and rounded-tip shape are there for long wear, which matters when a set runs past an hour.
The cable is worth a mention too. It's a woven MMCX detachable cable, so if it fails you replace the cable, not the earphones — and MMCX means you can swap in other cables, including ones with a mic for hands-free calls. BASN notes the connector also works with a range of other MMCX in-ears. The included L-type 1/4" jack adapts the 3.5mm plug for pro monitoring systems, phones, tablets and performing gear. There's a black carrying case, and a 12-month warranty behind the order.
Who should buy it: singers, drummers, mixing engineers and anyone who needs an isolating in-ear that stays put while they perform. The balanced highs, mids and low end makes it reasonable for studio mixing too, not just stage.
Who should skip it: if you need to blend two sources or boost a weak signal, this does neither — it's passive. And if you want the simplest possible setup, the memory wire takes a minute to shape the first time.
• Best for mixing two sources → ANLEON S1. Dual XLR inputs plus Level and Balance controls are the entire point.
• Best for hearing yourself over a loud band → ANLEON S1. High-power headphone output with a limiter, described as loud enough for drummers.
• Best for noise isolation → BASN Bsinger BC100. Up to 20dB of blocking from the ergonomic seal.
• Best for staying secure while you move → BASN Bsinger BC100. Memory earhooks and a custom-molded-style fit.
• Best for cable longevity and upgrades → BASN Bsinger BC100. Detachable MMCX, replaceable and swappable.
• Best for a fixed position on stage or in the studio → ANLEON S1. Aluminum body, corded power, no battery to manage.
• Best for plugging into a phone or tablet → BASN Bsinger BC100. 3.5mm jack with an L-type 1/4" adapter included.
• Best if you already own in-ears → ANLEON S1. You're only adding the amp.
In my opinion, most people searching these two names are really asking one question: do I need the amp or the earphones? If you're a drummer or keyboardist fighting to hear your own mix, I'd buy the ANLEON S1 — the dual XLR inputs and the loud, limited headphone output solve a problem no pair of earphones can. If you're a singer or gigging musician who just needs an isolating, secure in-ear, I'd buy the BASN Bsinger BC100 and pair it with whatever monitor feed you already have. They're not competitors so much as two halves of the same rig — and if you can stretch to both, that's the setup I'd actually want on stage. Check the current price on Amazon for each before you commit, since that's the one thing that changes.
FAQ
how to check headphones battery
how to check headphones battery on iphone
There's no battery indicator to find here because neither product is wireless or rechargeable. The BC100 connects over a wired 3.5mm jack, and the S1 plugs into a wall outlet — so your iPhone's battery widget won't show either one.
how to check headphones
Start with the connection. On the BC100, confirm the MMCX cable is fully seated and the 3.5mm plug (or the included L-type 1/4" adapter) is pushed in. On the S1, check that the 9V adapter is connected and that your XLR sources are live, then bring up the Level knob.
how to check headphones mic
The BASN Bsinger BC100 ships with a media-control cable, but any mic functionality depends on the cable you're using — BASN notes that other function cables need to be bought separately. The ANLEON S1 is an amplifier with no microphone of its own.
