If you want a neutral, open-back reference headphone you can wear for hours while you analyze or produce music, choose Amazon Renewed Sennheiser HD 560; if you need a studio-style over-ear with a large dynamic driver and a premium hybrid cable in the box, choose Linsoul Kiwikiwi Ears Ellipse.
• Amazon Renewed Sennheiser HD 560 — biggest strength: Open-back earcups plus E.A.R. angled driver alignment that recreates the triangular listening position of a hi-fi speaker setup, so the sound stage feels wide and the bass stays honest.
• Amazon Renewed Sennheiser HD 560 — biggest trade-off: Open-back design leaks sound both ways, so it is a poor fit for noisy rooms, offices, or anywhere you need isolation; it is also wired-only with no noise cancelling.
• Linsoul Kiwikiwi Ears Ellipse — biggest strength: A premium 50mm dynamic driver built with PU/PEK composite diaphragms, a copper ring, a CCAW high-tension voice coil and N42 magnets, paired with a hybrid silver-foil/OCC cable.
• Linsoul Kiwikiwi Ears Ellipse — biggest trade-off: The data sheet is thin on specs like impedance, frequency range and weight, so you have less to go on if you like matching a headphone to a specific amp or source.
• Who each pick is for: The HD 560 suits analytical listeners who want a linear, open, long-session headphone; the Ellipse suits buyers who want a big-driver studio-style can and a quality cable included.
The HD 560 is built around one idea: telling you the truth about your music. Its open-back earcups let sound waves expand naturally instead of trapping them against your ears, which is why the presentation feels spacious rather than boxed in. Sennheiser's E.A.R. (Ergonomic Acoustic Refinement) tilts the drivers to the natural angle of your ears, mimicking the triangle you would sit in with proper loudspeakers or in a high-end studio. The result is a wide sound field with detail you can pick apart — useful when you are checking a mix, editing audio, or just listening closely to a record you know well.
The tuning is deliberately neutral. The low end is extended and present enough to feel gratifying, but it is not boosted, so bass lines sit where the recording put them. That is the point of an analytical headphone: it reveals rather than flatters. Comfort matters here too, since linear sound is meant for long sessions. The headband is ultra-light and adjustable, the earcups articulate, and the earpads are soft enough to rest around the ear for hours. The cable detaches, and the supplied 6.3mm plug unscrews to reveal a 3.5mm jack, so the same headphone works with headphone amps, audio interfaces, A/V receivers and everyday 3.5mm sources. Impedance is 120 ohm and the rated frequency range runs from 6 Hz to 38 kHz.
Who should buy it: producers, editors, students and detail-focused listeners who want an honest, open, wired headphone for a desk setup and long wearing sessions. Who should skip it: anyone who needs isolation on a commute or in a shared office, anyone who wants wireless or noise cancelling, and anyone who prefers a warm, bass-heavy signature over a neutral one. As a renewed unit it also carries a 90-day limited warranty, which is worth weighing if you like long coverage windows.
The Ellipse is aimed squarely at the studio-grade side of the market. Its centerpiece is a new 50mm dynamic driver, and that size matters: a larger diaphragm moves more air, which is typically how a headphone builds a fuller low end and a more physical sense of scale. The driver is not off-the-shelf either — Linsoul specifies custom PU and PEK composite diaphragms with an ultra-pure copper ring, driven by a custom CCAW high-tension voice coil and strong N42 high-performance magnets. In plain terms, that is a parts list built for control and efficiency rather than for hitting a cost target.
The second half of the story is the cable. The bundle includes a Tripowin Nova monitor cable built with a 4-strand hybrid architecture combining silver foil and OCC copper, wrapped in a PVC jacket. Linsoul's pitch is that this minimizes signal loss and widens frequency response while staying tangle-free. I would treat the sonic claims with reasonable skepticism — cables are the most argued-about part of this hobby — but the practical upshot is real: you get an audiophile-grade cable in the box instead of having to buy one separately, and a PVC jacket is genuinely nicer to live with than stiff, memory-prone stock wiring.
Who should buy it: listeners and home-studio users who want a large-diaphragm over-ear with premium driver materials and a quality cable included, and who are comfortable buying from a brand known for its in-ear and cable work rather than from a legacy headphone house. Who should skip it: anyone who needs published impedance and frequency-range figures to match a specific amplifier, anyone who wants an open-back sound stage, and anyone who wants the reassurance of a long, clearly documented warranty term.
Side-by-Side: Which Should You Choose?
• Best for analytical, neutral listening → Amazon Renewed Sennheiser HD 560. The linear tuning and open-back design exist to reveal the recording, not to sweeten it.
• Best for long wearing sessions → Amazon Renewed Sennheiser HD 560. Ultra-light adjustable headband, articulating earcups and soft earpads are specified for exactly that.
• Best for source flexibility → Amazon Renewed Sennheiser HD 560. The detachable cable's 6.3mm plug unscrews to a 3.5mm jack, covering amps, interfaces, receivers and everyday gear.
• Best for a large driver and premium materials → Linsoul Kiwikiwi Ears Ellipse. A 50mm dynamic driver with PU/PEK composite diaphragms, a copper ring and N42 magnets is a serious spec sheet.
• Best for getting a quality cable included → Linsoul Kiwikiwi Ears Ellipse. The Tripowin Nova hybrid cable ships in the box, so there is nothing extra to buy.
• Best for isolation or quiet listening in shared spaces → neither, honestly. The HD 560 is open-back and leaks; the Ellipse is a wired over-ear with no noise-cancelling listed. If isolation is the priority, look elsewhere.
• Best for buyers who want published specs to match an amp → Amazon Renewed Sennheiser HD 560. With 120 ohm impedance and a 6 Hz–38 kHz rating, you know what you are plugging into.
I would buy the Amazon Renewed Sennheiser HD 560. In my opinion, it is the more complete, more predictable package: a defined tuning philosophy, a documented 120 ohm impedance, a stated 6 Hz–38 kHz range, a detachable cable that adapts between 6.3mm and 3.5mm, and comfort engineered for long sessions. The Ellipse has the more exciting driver story and a better cable in the box, and if a big 50mm diaphragm and included hybrid wiring are what you are chasing, it is a legitimate pick. But when I am spending my own money on a headphone I will wear every day, I want the one whose behavior I can reason about before it arrives — and that is the HD 560.
It is the HD 560S model, sold through Amazon Renewed, and it comes with a 90-day limited warranty. The specs — 120 ohm impedance, 6 Hz to 38 kHz, detachable cable with a 6.3mm plug and 3.5mm adapter — are the model's standard figures.
Linsoul does not publish an impedance figure in the product data, so I cannot say definitively. A 50mm dynamic driver with N42 magnets and a high-tension voice coil is typically easy enough to drive from a decent source, but if you plan to use a dedicated amp, check the current specs on the product page before buying.
In my opinion the HD 560 is the safer choice for analytical work, because its neutral response and open-back, angled-driver staging are designed to reveal detail rather than add color. The Ellipse is aimed at studio-grade clarity too, and its larger driver will likely give you more low-end weight — good for tracking and casual production, less ideal if you want the flattest possible reference.
Prices change constantly and depend on the seller and condition, so I will not quote a number. Compare the current price on Amazon for both, and remember to factor in the Ellipse's included cable and the HD 560's 90-day warranty when you weigh the two.
