• Asobilor Dual 3.5mm — biggest strength: the foldable plug. It switches between single and double plug configurations, so you're covered whichever seat jack you land on.
• Asobilor Dual 3.5mm — biggest trade-off: it's a pure passive adapter. No DAC chip, no aluminum shell, just a gold-plated connector in a tiny plastic-bodied plug.
• Togconn 1/8 — biggest strength: the built-in intelligent DAC chip with decoding up to 24Bit/96kHz, plus OFC conductors and an aluminum shell.
• Togconn 1/8 — biggest trade-off: it's a fixed dual-plug design, so it's aimed squarely at dual-jack airline seats rather than doubling as a general-purpose adapter.
• Who Asobilor is for: travelers who want a pocket-sized, foldable adapter that handles both single and double jacks and works with Bose headphones.
• Who Togconn is for: flyers who mostly sit at dual-jack seats and want the extra decoding hardware and metal build.
The Asobilor Dual 3.5mm is a tiny piece of travel kit — it measures 0.2 x 1.6 x 0.5 inches and weighs 10 grams. That's the kind of thing that disappears into a jacket pocket or a seat-back pouch and never becomes a burden. The whole pitch here is flexibility: the plug folds into either a single or a double configuration, so you don't have to guess what the airline installed in your armrest. Plug your headphone cable into the 3.5mm female end, plug the adapter into the aviation jack, and you're listening.
The gold-plated tip is the other functional detail worth noting. Gold plating on a connector is about signal transfer and corrosion resistance over time, and Asobilor specifically frames it as improving signal input and reducing external noise. Take that as a design intent rather than a promise of dramatic sound changes — the real benefit of plating shows up over repeated plugging and unplugging, which is exactly what a travel adapter endures.
Compatibility is broad. Asobilor lists Bose 700, QC2, QC3, QC15, QC20, QC25, QC35, QC35ii, NC700, SoundLink, SoundLinkII, AE2, AE2i and AE2W, and it also works with most devices that have a standard single or dual 3.5mm output. There's a 12-month warranty backing it.
Togconn 1/8: Who It's For
Togconn 1/8 takes a different approach: it builds the adapter around electronics rather than pure mechanical flexibility. The headline component is an intelligent DAC chip with stable decoding performance and compatibility with audio sampling rates up to 24Bit/96kHz. Togconn describes it as low-power, with high-definition sound and noise reduction as the stated goals. For someone who cares about getting a clean digital-to-analog conversion out of an in-flight entertainment system, that's the reason to pick this one over a passive adapter.
The materials story is also more premium. Togconn uses OFC inner conductors for signal transmission, 24K gold-plated connectors for corrosion resistance, and aluminum shells for better heat dissipation. That aluminum housing is a genuine practical difference on a long-haul flight — metal shells feel more substantial and handle repeated handling better than thin plastic.
The catch is the plug configuration. This is listed as a dual 3.5mm male to 3.5mm female converter, and the compatible devices field names "3.5mm Airplane Flight Headphone" specifically. It's a fixed dual-plug design, so it's built for the seats that use two prongs rather than being a foldable, do-everything adapter. It's plug and play, and it carries a 12-month warranty with a stated 24-hour response window for questions.
Buy it if you usually fly aircraft with dual-jack seats and you value the DAC chip, OFC conductors and aluminum shell. Skip it if you want one adapter that also collapses down to a single plug for older or mixed cabin setups.
• Best for unknown or mixed seat jacks → Asobilor Dual 3.5mm. The foldable single/double plug means you're not stuck if the seat doesn't match your adapter.
• Best for dual-jack cabins specifically → Togconn 1/8. It's designed around the dual 3.5mm male configuration.
• Best for audio decoding quality → Togconn 1/8. The intelligent DAC chip and 24Bit/96kHz support are the differentiators.
• Best for build materials → Togconn 1/8. OFC conductors, 24K gold plating and aluminum shells versus Asobilor's plastic body with a gold-plated tip.
• Best for portability and packability → Asobilor Dual 3.5mm. At 10 grams and under two inches long, it's about as small as this category gets.
• Best for Bose owners → Asobilor Dual 3.5mm. The compatibility list explicitly covers the QC and NC700 families along with SoundLink and AE2 models.
• Best for low-power, passive simplicity → Asobilor Dual 3.5mm. No electronics inside means nothing to decode and nothing to power.
• Best for a metal-shell feel in hand → Togconn 1/8. The aluminum housing is the more robust-feeling option.
In my opinion, most travelers should buy the Asobilor Dual 3.5mm. The foldable plug solves the single biggest annoyance of in-flight audio: not knowing which jack your seat has until you're already settled in. It's 10 grams, it covers the Bose models a lot of flyers already own, and it does the core job without fuss.
I'd pick the Togconn 1/8 instead if you fly dual-jack aircraft regularly and want the DAC chip, OFC wiring and aluminum shell. That's a real upgrade in materials and decoding — just a less flexible one in the plug department. Either way, check the current price on Amazon before deciding, since that's the one variable I can't weigh for you.
what headphones for airplane
Any headphones with a standard 3.5mm jack work with either adapter — you plug your headphone cable into the adapter's 3.5mm female end, then into the seat jack. Asobilor explicitly lists Bose 700, QC2/3/15/20/25/35/35ii, NC700, SoundLink and AE2 models, and both adapters fit most 3.5mm devices. The adapter is what bridges your headphones to the plane, not the headphones themselves.
what is the best headphones for airplanes
I can't name a "best" headphone, but I can tell you what the adapters support. If you already own Bose QC or NC700 headphones, the Asobilor Dual 3.5mm lists them as compatible and gives you the foldable plug for single or double jacks. If your priority is the adapter's decoding, the Togconn 1/8 adds a DAC chip rated up to 24Bit/96kHz.
what earphones for airplane
The same rule applies: any earphone with a 3.5mm plug works, because both adapters present a 3.5mm female socket. What matters more is the jack at your seat. Choose the Asobilor if you need the foldable single/double option, or the Togconn if your cabin uses dual 3.5mm jacks and you want its OFC conductors and aluminum shell.
what kind of headphones for airplane
You want headphones with a detachable or standard 3.5mm cable, since that's what plugs into these adapters. Both Asobilor and Togconn convert the airline jack to a 3.5mm female input, so wired over-ear or in-ear models are the natural fit. Asobilor's foldable plug adds the flexibility to handle either jack layout you encounter.
