• SIMOLIO Dual — biggest strength: A complete 2.4GHz wireless TV system built for intelligibility — voice clarity, a tone control, left/right balance, a spare always-charged battery, and a bypass that lets the headphones and a soundbar run off the same optical port.
• SIMOLIO Dual — biggest trade-off: It is a TV-listening tool, not a music headphone. It is incompatible with Bluetooth-only TVs and needs a separately purchased HDMI converter on HDMI-only TVs, and it is not available for pacemaker carriers.
• Linsoul Kiwi Ears Ellipse — biggest strength: Wired, over-ear, studio-grade presentation from a premium 50mm dynamic driver with PU/PEK composite diaphragms, paired with an audiophile hybrid cable in 3.5mm and 4.4mm options.
• Linsoul Kiwi Ears Ellipse — biggest trade-off: Passive isolation only, wired-only, and it depends on your own source and amplification — no batteries, no transmitter, no TV-specific features.
• For the senior or hard-of-hearing TV viewer who wants their own volume without blasting the room → SIMOLIO Dual.
• For the listener who wants an open, detailed monitor for mixing, editing or focused music listening → Linsoul Kiwi Ears Ellipse.
The SIMOLIO Dual is a purpose-built TV listening system, and it says so plainly in its design. It runs on 2.4GHz RF rather than Bluetooth, which means no pairing step and no lip-sync delay to fight with. The signal is rated to hold up to roughly 164 feet and can pass through walls and ceilings, so you can walk to the kitchen mid-program and keep the audio. For anyone who has ever given up on a flaky Bluetooth connection halfway through a movie, that reliability is the whole point.
The feature list reads like a checklist written by someone who lives with hearing difficulty. Voice clarity and noise reduction push dialogue forward against background music and effects. A tone control lets you hunt for the frequency range where speech clicks for you, and a balance control adjusts left and right independently so one ear can be brought up to match the other. Mono or stereo is selectable. There is an ambient sound mode that lets you hear someone talking to you nearby without pulling the eartips out — a small thing that matters a lot in a shared living room.
Battery life is quoted at about 14 hours per charge with a 3-hour charge time, and the base station holds a second battery that stays topped up and ready, so a swap takes seconds. The optical bypass is the clever bit: with an optical connection, the headphones and your existing soundbar or AV receiver can share the same optical output, so you listen at your own volume while everyone else hears the TV normally through the speakers.
Who should buy it: seniors and hard-of-hearing viewers who want clear, loud dialogue at their own level without disturbing family or neighbors. Who should skip it: anyone with severe hearing difficulty or who relies on hearing aids — this cannot replace a hearing aid — and anyone with a pacemaker, since it is not available for pacemaker carriers. Also skip it if your TV is Bluetooth-only, or if your only free port is HDMI and you do not want to buy an HDMI converter separately.
The Ellipse is a different animal entirely. This is a wired, over-ear headphone built around a 50mm dynamic driver with custom PU and PEK composite diaphragms and an ultra-pure copper ring. The rated frequency range covers 20Hz to 20,000Hz. It ships with the Tripowin Nova monitor cable — a 4-strand hybrid architecture combining silver foil and OCC strands — which Linsoul says minimizes signal loss and widens the frequency response, wrapped in a PVC jacket to resist tangling. You get both a 3.5mm and a 4.4mm jack option, which tells you this is aimed at people plugging into real gear: an interface, a DAC/amp, or a balanced output.
The enclosure is polyurethane in black, and the ear placement is over-ear. Noise control is listed as sound isolation, meaning it relies on the physical seal and fit of the earcups rather than active electronics. There are push-button and touch controls on the headphone itself.
What this means in daily use: this is a headphone for sitting down and listening. Editing a podcast, tracking a mix, checking a vocal take, or just working through an album with attention. The 4.4mm balanced option and the cable construction signal that the Ellipse expects a decent source to show what it can do — plug it into a laptop headphone jack and you are hearing a fraction of the story.
Who should buy it: listeners and creators who want a wired, over-ear, studio-oriented monitor and already own or plan to own a proper source. Who should skip it: anyone who wants wireless freedom, TV-specific voice enhancement, or a spare-battery system — none of that is here. If you watch TV from the couch and want to hear dialogue better, this is the wrong tool.
Side-by-Side: Which Should You Choose?
• Best for TV dialogue and hard-of-hearing viewers → SIMOLIO Dual. Voice clarity, tone control and balance control are built for exactly this.
• Best for wireless freedom and range → SIMOLIO Dual. 2.4GHz RF with no pairing and up to roughly 164 feet of range through walls.
• Best for battery convenience → SIMOLIO Dual. About 14 hours per charge, 3-hour charge time, plus a spare battery kept charged in the base.
• Best for watching TV with others in the room → SIMOLIO Dual. The optical bypass lets the headphones and your soundbar share one optical output.
• Best for sharing the couch without sharing the volume → Linsoul Kiwi Ears Ellipse, with a caveat. It is wired and isolates sound, so it keeps your audio to yourself, but it does nothing to boost TV speech.
• Best for plugging into a DAC, amp or balanced output → Linsoul Kiwi Ears Ellipse. It offers both 3.5mm and 4.4mm jacks.
• Best for a simple setup with no extra boxes → Linsoul Kiwi Ears Ellipse. Wired means no transmitter, no power adapter, no converter.
In my opinion, these two products are not really competing — they solve different problems, and the right answer is whichever problem is yours. If your goal is hearing the TV clearly at your own volume without disturbing anyone, I would buy the SIMOLIO Dual. Its voice clarity, tone and balance controls, spare battery and soundbar bypass are all pointed at that single job, and nothing on the Ellipse replaces any of it.
If your goal is open, detailed, wired monitoring for music or studio work, I would buy the Linsoul Kiwi Ears Ellipse. It is the more rewarding headphone for listening, provided you feed it a proper source.

how to open back headphones work
Open-back headphones use earcups with vents or grilles that let air move between the driver and the outside world instead of sealing it in. That open airflow reduces the pressure buildup behind the driver, which typically produces a wider, more natural sense of space. The trade-off is that sound leaks out and outside noise leaks in, so they are best used in a quiet room rather than on a commute.
what is open back studio headphones
It refers to over-ear headphones designed for studio and critical-listening work, with vented earcups that trade isolation for a more open, spacious presentation. Engineers use them for mixing and referencing because the soundstage feels less closed-in. The Linsoul Kiwi Ears Ellipse is an over-ear, wired, studio-oriented design, though it is listed with sound isolation rather than an open-back venting spec, so treat it as a studio monitor first and confirm the enclosure type before buying.
what are the best open back headphones
There is no single answer, because "best" depends on whether you need isolation or openness, wireless or wired, and a TV-friendly feature set or a studio one. In this comparison, the SIMOLIO Dual is the better pick if you want clear TV dialogue at your own volume, while the Linsoul Kiwi Ears Ellipse is the better pick for wired, over-ear monitoring with a 50mm dynamic driver.
are open back headphones better
They are better for some things and worse for others. The open design usually gives a wider, more natural soundstage, which many listeners prefer for music and mixing. But they leak sound both ways, so they are poor for noisy environments, and they do nothing to boost TV speech — which is exactly why the SIMOLIO Dual exists as a closed, wireless, TV-focused system.
