If you want a secure, noise-isolating in-ear monitor for exercise, choose BASN High-Definition; if you need an over-ear, open-back style studio monitor for critical listening and mixing, choose Linsoul Kiwi Ears Ellipse. That's the short version, and for anyone hunting the best earphones for exercise, the split really does come down to fit and isolation versus open, airy staging. I'll walk through the open back monitor headphones angle in detail, then tell you which one I'd actually buy.
• BASN High-Definition — biggest strength: dual dynamic drivers with neodymium magnets, a deep in-ear seal, and a detachable MMCX cable, all built for movement and stage use.
• BASN High-Definition — biggest trade-off: it's a wired, in-ear design with 18Ω impedance, so it leans on your source and on getting a good tip seal rather than on room-filling openness.
• Linsoul Kiwi Ears Ellipse — biggest strength: a large 50mm dynamic driver with PU/PEK composite diaphragms and a hybrid silver-foil/OCC cable aimed at studio-grade clarity.
• Linsoul Kiwi Ears Ellipse — biggest trade-off: it's an over-ear, open, wired headphone with no inline mic or wireless, so it's tethered and not built for sweaty movement.
• Who each pick is for: BASN for musicians and gym-goers who want isolation and a locked-in fit; Ellipse for producers and listeners who want an open, wide presentation at a desk.
The BASN High-Definition is an in-ear monitor built around two dynamic drivers with neodymium magnets, and the whole design philosophy is accuracy on a stage. The frequency response runs 20Hz–20kHz with 93dB sensitivity and 18Ω impedance, which means it's efficient enough to run off a phone or a receiver pack without much fuss. The over-ear hook shape and five pairs of medical-grade eartips exist for one reason: a seal. That seal is what cancels ambient noise — the spec sheet rates it up to 35dB of isolation — and sends your guitar, voice or drums straight to your ears.
Who should skip it? If you want an open, spacious soundstage for mixing at a desk, this isn't that — it's an isolating in-ear, and the closed, sealed presentation is the point. It's also wired only, so if you need wireless freedom, look elsewhere. And if you're a heavy sweater who wants something you can rinse, note that the sheet doesn't list a water-resistance rating here. In my opinion, this is the pick for the person who wants the sound delivered into their ears, distractions blocked out, and the fit locked down for activity.
Linsoul Kiwi Ears Ellipse: Who It's For
The Linsoul Kiwi Ears Ellipse is a different animal entirely. It's an over-ear, open, wired headphone built around a premium 50mm dynamic driver — a big driver by any measure. That driver uses custom PU and PEK composite diaphragms with an ultra-pure copper ring, driven by a CCAW high-tension voice coil and N42 high-performance magnets. The included cable is a four-strand silver-foil and OCC hybrid, which the brand says minimizes signal loss and widens frequency response for what it calls studio-grade clarity.
This is designed for professional audio monitoring, and the compatibility list backs that up: music production gear, laptops, desktops, gaming consoles, tablets, phones, smart speakers and TVs. If you're mixing, editing, or just want an open, airy presentation where instruments feel spread out around you instead of sealed inside your head, the over-ear cup design and open approach are the whole appeal. The 3.5mm jack and wired connection mean you're tethered to your source, which is normal for studio work but worth knowing before you buy.
Who should skip it? Anyone who wants to move. This is not a workout companion — over-ear cups, a wired cable and no inline mic or wireless make it a desk and studio tool, not a treadmill one. The sheet lists it as waterproof, but waterproofing isn't the same as sweat-proof-and-secure-for-running, and an open over-ear won't stay put through burpees. If your priority is the best headset for exercise, this isn't it. If your priority is a wide, open, analytical listen at a desk, it's a strong fit.
• Best for exercise and movement → BASN High-Definition: the over-ear hooks, adjustable fit and 35dB isolation are built for staying put and blocking gym noise.
• Best for open, spacious listening → Linsoul Kiwi Ears Ellipse: the over-ear cup design and 50mm driver are aimed at a wide, airy presentation.
• Best for stage and rehearsal → BASN High-Definition: the in-ear seal and dual neodymium drivers are tuned for musicians hearing themselves clearly.
• Best for studio monitoring and mixing → Linsoul Kiwi Ears Ellipse: it's explicitly positioned for professional audio monitoring.
• Best for calls and hands-free → BASN High-Definition: its included cable has a built-in mic and remote; the Ellipse cable has none.
• Best for repairability → BASN High-Definition: the detachable MMCX connector lets you replace the cable, and it works with several major-brand earphones.
• Best for a phone or receiver pack → BASN High-Definition: 18Ω impedance and 93dB sensitivity keep it easy to drive.
• Best for a desk setup with a laptop or console → Linsoul Kiwi Ears Ellipse: its compatibility list covers production gear, computers, consoles and TVs.
I'd buy the BASN High-Definition. In my opinion, it's the more versatile of the two for most people — the sealed fit, detachable MMCX cable, inline mic and locked-in over-ear hooks make it the better all-rounder, and it's the obvious choice if exercise is anywhere on your list. The Ellipse is the more specialized tool: a genuine open, over-ear studio monitor with a big 50mm driver for critical desk listening. If you mostly mix at a desk, get the Ellipse. If you want one set that handles the gym, the stage and the commute, get the BASN. Either way, check the current price on Amazon through the button on this page before you commit.
how to open back headphones work
Open-back headphones like the Linsoul Kiwi Ears Ellipse use over-ear cups that let air move freely rather than sealing against your head. That openness is what creates a wider, more spacious presentation, but it also means they leak sound and block very little external noise — the opposite of the isolating BASN in-ear design.
what is open back studio headphones
An open-back studio headphone is a wired, over-ear design intended for monitoring and mixing, where an airy soundstage matters more than isolation. The Ellipse fits that description with its 50mm dynamic driver and over-ear cups, and its compatibility list includes music production equipment, laptops and consoles.
what are the best open back headphones
There's no single answer, but for this matchup the Ellipse is the open, over-ear option — a 50mm driver with PU/PEK composite diaphragms built for studio-grade clarity. If you actually want isolation, the BASN High-Definition is the better pick, since an open design is meant to let sound in and out.
are open back headphones better
Better for what? For an open, spacious, analytical listen at a desk, open-back designs like the Ellipse have a real advantage. For exercise, commuting or blocking noise, they're worse — the BASN High-Definition's in-ear seal and up-to-35dB isolation are the better fit. Match the design to the job.
