• SIMOLIO 2 — biggest strength: True infrared, dual-channel over-ear headphones sold as a two-pack, made for car headrest and ceiling-mounted DVD systems and IR TVs, with no Bluetooth pairing at all.
• SIMOLIO 2 — biggest trade-off: It is not a general-purpose headphone. No Bluetooth, no active noise cancelling, and it needs an IR source (your car system, or an IR transmitter you buy separately) to be wireless.
• Srhythm NiceComfort 25Pro — biggest strength: Active noise cancelling that the brand says quells up to 90% of ambient noise, Bluetooth 5.3, low-latency game mode and a claimed 40 hours of playtime in one compact folding package.
• Srhythm NiceComfort 25Pro — biggest trade-off: It is a single headphone, not a pair, and the noise cancelling is not total — the brand itself notes human voices still come through and ANC is less effective in quiet rooms.
• Pick SIMOLIO 2 if you are outfitting a car with a factory rear-seat entertainment system and want two kids listening at once, each on their own channel.
• Pick Srhythm NiceComfort 25Pro if you want one modern wireless headphone for music, calls, gaming and flights with real noise cancelling.
The SIMOLIO 2 is a very specific tool, and that specificity is its whole appeal. It is an infrared headphone, not a Bluetooth one — the brand repeats that warning again and again, and it matters. Infrared means the audio travels on light, the same way your car's factory rear-seat system already sends sound to its own headphones. That is why the compatibility list is so long and so granular: Honda Odyssey, Pilot, Accord, CR-V; Chrysler Town & Country and Pacifica; Dodge Grand Caravan and Durango; Chevy Tahoe, Suburban and Silverado; Ford Expedition and Explorer; Toyota Sienna and Highlander; Nissan Armada; GMC Yukon; Kia Sedona, and many more, spanning model years from the early 2000s into the 2020s. If your vehicle has a ceiling-mounted or headrest DVD player, this is the kind of headphone that was designed to talk to it.
What it is not: a music headphone for your commute. There is no Bluetooth, no active noise cancelling (only passive sound isolation), and no microphone for calls. The IR wireless mode only works when it can see an IR transmitter — in the car that is your factory system, at home you would need to buy a compatible transmitter separately. If you want one pair of headphones for everything, this is the wrong product. If you want to end the "he's watching my movie" argument in the back seat, it is exactly right.
Srhythm NiceComfort 25Pro: Who It's For
The NiceComfort 25Pro is the opposite philosophy: one headphone that tries to do everything well. The headline feature is active noise cancelling, which Srhythm describes as combining a snug physical seal with electronic cancellation to quell up to 90% of ambient noise. The brand is refreshingly honest about the limits — it is not 100% cancelling, human voices are not eliminated, and ANC is less effective in a quiet environment. That is a realistic description of what ANC does. It works in both wired and wireless mode, so you can keep the cancellation on even when you plug in the included 3.5 mm aux cable.
On the wireless side you get Bluetooth 5.3 with a stated range of 30–50 feet without obstacles, the ability to pair with two devices at once and switch between music, calls and video without reconnecting, and a low-latency mode aimed at gaming and video so the audio stays in sync. The drivers are 40 mm dynamic, impedance is 32 ohm, and the brand lists around 40 hours of average playtime with a 2.5-hour charge over USB-C. There is an over-voltage protection feature for safer charging. The microphone only works in wireless mode — worth knowing if you plan to take calls.
The physical design suits travel and school. It weighs 0.4 lb (204 g), the earcups are over-ear with a leather-and-plastic build, and the buttons have been moved to the bottom of the ear-cup as side square buttons for easier operation. It folds compactly, which is the point of the "compact foldable" formula, and Srhythm says it stays comfortable even if you wear glasses. In the box you get the headphones, a protective case, a 3.5 mm aux cable, a 6.35 mm adapter, a two-pin airplane adapter and a USB-C charging cable — a genuinely travel-ready kit. There is a one-year warranty.
Side-by-Side: Which Should You Choose?
• Best for in-car rear-seat DVD systems → SIMOLIO 2. It is built for factory IR entertainment systems and lists compatibility across a huge range of vehicles.
• Best for two kids watching different things → SIMOLIO 2. Dual A/B channels plus a two-pack means two streams, no interference.
• Best for noise cancelling on a plane or train → Srhythm NiceComfort 25Pro. Active noise cancelling, up to 90% of ambient noise per the brand.
• Best for battery life → Srhythm NiceComfort 25Pro. Around 40 hours versus roughly 20 hours on the SIMOLIO 2.
• Best for wireless freedom with your phone → Srhythm NiceComfort 25Pro. Bluetooth 5.3, dual-device pairing, low-latency game mode.
• Best for a wired, no-pairing setup → SIMOLIO 2. Infrared plus a 3.5 mm jack, no Bluetooth to configure.
• Best for travel accessories out of the box → Srhythm NiceComfort 25Pro. Protective case, airplane adapter and adapters are included.
• Best for kids' head fit → SIMOLIO 2. The memory stainless-steel headband flexes and angles for smaller heads.
In my opinion these are not really competitors — they solve different problems, and the right answer depends entirely on your car. If you have a factory rear-seat entertainment system and two kids, I would buy the SIMOLIO 2: the dual-channel two-pack is the only one of these that actually fixes the "everyone wants their own movie" problem, and it is purpose-built for exactly that job. If instead you want one headphone for commuting, flying, studying and gaming, I would buy the Srhythm NiceComfort 25Pro — the active noise cancelling, Bluetooth 5.3, 40-hour playtime and folding travel kit make it the far more versatile everyday pick. Check the current price on Amazon before you commit, since both are sold there directly.
No. It is an infrared headphone, not a Bluetooth one, and the brand states this repeatedly. It works wirelessly only with an IR source such as a compatible car DVD system, or with an IR transmitter you buy separately. It also has a 3.5 mm jack for wired listening.
No. Srhythm says it cancels up to 90% of ambient noise, not 100%, that human voices are not eliminated, and that ANC is less effective in quiet environments. It is best at steady low-frequency noise like engine and cabin drone.
The SIMOLIO 2, clearly. It is sold as a two-pack, uses dual A/B channels so two kids can watch different movies without interference, and has a flexible memory stainless-steel headband that adjusts to smaller heads. The Srhythm is a single adult-oriented Bluetooth headphone.
The Srhythm NiceComfort 25Pro, at around 40 hours of average playtime per the brand, versus roughly 20 hours for the SIMOLIO 2. Both charge over their own included cables, and the Srhythm can also run wired via the 3.5 mm aux cable when the battery is low.
