How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, stage-ready in-ear monitor with a detachable MMCX cable system and a full accessory kit, choose BASN Bmaster Triple Drivers; if you need a full-size, over-ear planar magnetic headphone with a big 106mm driver and a closed-back isolating enclosure for long listening sessions, choose Monoprice Monolith M1570C.
• BASN Bmaster Triple Drivers — biggest strength: A triple-driver hybrid setup (two dynamic drivers plus one balanced armature) in a tiny in-ear shell, with two detachable MMCX cables included and a deep accessory bundle.
• BASN Bmaster Triple Drivers — biggest trade-off: It's plastic-bodied and cable-dependent, so it's a lightweight, purpose-built tool rather than a luxury object — and it lives inside your ear canal, which not everyone enjoys.
• Monoprice Monolith M1570C — biggest strength: A 106mm planar magnetic driver with a dual linear symmetry magnet array inside a closed-back over-ear housing, tuned for a wide soundstage and tight bass.
• Monoprice Monolith M1570C — biggest trade-off: It's a big, wired, over-ear headphone that needs a 1/4-inch jack and a proper amp-friendly source, and it weighs under 23 ounces — comfortable for long sessions, but still a lot of headphone on your head.
• Who the BASN is for: Musicians, audio engineers, and anyone who wants isolating in-ears for stage, monitoring, commuting, or noisy rooms.
• Who the Monolith is for: Audiophiles and home listeners who want a closed-back planar for critical listening, mixing, or late-night sessions without leaking sound.
The BASN Bmaster Triple Drivers is built around a simple idea: get a lot of driver technology into a small, isolating in-ear. It runs two dynamic drivers plus one balanced armature, with a rated impedance of 34 ohms and a frequency range of 20 Hz to 20,000 Hz. In practice that combination is what gives it the sound character described in the specs — full low end, a clear midrange, and treble that stays detailed rather than harsh. The balanced armature handles the upper detail, the dynamic drivers carry the weight, and the result is a coherent, balanced presentation rather than a bass-only party trick.
The accessory list is genuinely unusual at this tier. You get two cables — an inline remote/mic cable and an OFC silver-plated cable — both detachable via MMCX connectors that rotate 360 degrees, so you can swap cables or replace one if it fails. There's a 6.3mm adapter for plugging into pro gear, a cable clip, a cleaning tool, tangle-free velcro strips, and a carrying case. The shell is plastic and the model is the Bmaster-Blue, so it's a practical tool, not a statement piece.
Who should skip it? If you dislike things sitting inside your ear canal, or you want a single pair of over-ear headphones for everything, this isn't your product. And if you want a full-size soundstage with a big planar driver, no in-ear will scratch that itch.
Monoprice Monolith M1570C: Who It's For
The Monoprice Monolith M1570C is a different animal entirely. This is a full-size, over-ear, closed-back planar magnetic headphone built around a 106mm planar driver using a dual linear symmetry magnet array. Planar drivers move a thin diaphragm across a large surface area, and Monoprice has tuned this one for an extended, airy top end and bass that's tight and deep rather than boomy. The 60-ohm nominal impedance and 20 Hz–20,000 Hz range tell you it's aimed at listeners who'll pair it with a decent source rather than a phone dongle.
The closed-back housing is the headline feature for a lot of buyers. Outside noise stays out and your music stays in, which is the whole point of a closed design: you can listen critically in a room that isn't silent, and the person next to you isn't forced to hear your session. The specs call it out as a fit for less-than-silent environments, and I'd agree — this is the kind of headphone you reach for on a late-night listening session or in a home studio where isolation matters.
Comfort looks well thought out. It weighs under 23 ounces, uses a padded headband, and ships with large faux leather earpads plus two swappable memory foam sets — one lambskin and one velour. The earpads are removable, so you can change the feel or the sound signature without buying a new headphone. That's a real long-term ownership perk.
Side-by-Side: Which Should You Choose?
• Best for stage and live performance → BASN Bmaster Triple Drivers. The earhook, secure in-ear fit, and detachable MMCX cables are designed for movement and quick cable swaps.
• Best for sound isolation in a noisy room → Monoprice Monolith M1570C. The closed-back over-ear design keeps outside noise out and your music in, which in-ears can't match for passive full-spectrum blocking.
• Best for long listening sessions → Monoprice Monolith M1570C. Under 23 ounces with a padded headband and swappable memory foam earpads is built for hours, whereas in-ears eventually fatigue the canal.
• Best for portability and travel → BASN Bmaster Triple Drivers. The carrying case, compact shell, and velcro cable ties make it a go-anywhere kit.
• Best for critical home listening and mixing → Monoprice Monolith M1570C. The 106mm planar driver and wide soundstage are aimed squarely at detail-oriented listeners.
• Best for cable customization and repairability → BASN Bmaster Triple Drivers. Two included cables plus 360-degree rotating MMCX connectors mean you can replace or upgrade the cable yourself.
• Best for plugging into pro gear → BASN Bmaster Triple Drivers. The included 6.3mm adapter lets it go straight into a mixing desk or interface; the Monolith already uses a 1/4-inch plug for the same kind of gear.
• Best for someone who hates things in their ears → Monoprice Monolith M1570C. Simple as that.
In my opinion, the right pick comes down to where you listen, not which is "better." If your listening happens on a stage, in a rehearsal room, on a commute, or anywhere you need isolation in a tiny package, I'd buy the BASN Bmaster Triple Drivers — the triple-driver hybrid tuning, secure earhook fit, and dual detachable MMCX cables make it a genuinely flexible tool, and the accessory kit covers almost everything you'd otherwise buy separately.
If your listening happens at a desk or in a chair, and you want a big planar soundstage with a closed-back enclosure you can wear for hours, I'd buy the Monoprice Monolith M1570C instead. The 106mm planar driver and swappable memory foam earpads are the reasons. Check the current price on Amazon for whichever one fits your setup, then commit.
It's wired and in-ear with an earhook that keeps it in place, so it handles movement well. But it's not marketed as sweat-proof or water-resistant, so treat it as a stage and monitoring tool rather than workout gear.
It's a 60-ohm planar magnetic headphone with a 1/4-inch plug and mini 4-pin XLR connectors, so it's clearly built for a proper desktop source or amp rather than a phone. Planar drivers generally reward good amplification.
The BASN relies on eartip seal inside your ear canal, which can block a lot of noise if you get the fit right. The Monolith uses a closed-back over-ear housing that keeps sound in and out more consistently. For blocking steady background noise, a good in-ear seal often wins; for keeping your music from leaking, the closed-back over-ear wins.
Yes to both. The BASN uses 360-degree rotating MMCX connectors and ships with two cables, so replacement or upgrades are straightforward. The Monolith's earpads are removable and it comes with lambskin and velour memory foam sets, so you can swap the feel and tuning.
