If you want a detachable-cable planar headphone with a 106mm driver, choose FiiO FT7; if you need a lightweight, high-impedance open-back reference headphone, choose Generic ATH-R70X. For flights, I’d choose the FT7 only if you’re set on an open-back headphone and can accept that neither model is designed to isolate you from cabin noise.
The ATH-R70X is lighter on paper, but its 470-ohm impedance and open-back design make it a more specialized listening choice.
FiiO FT7 vs Generic ATH-R70X at a Glance
• FiiO FT7 strength: 106mm planar magnetic drivers, a detachable cable, and two interchangeable ear-pad types. Trade-off: It is open-back and weighs 427g.
• For flights: Neither model offers active noise cancelling or a closed-back seal. Both let surrounding sound in.
• Choose the FT7 if planar drivers, pad options, and a modular cable matter most.
• Choose the ATH-R70X if you want a lighter reference headphone for a desk or studio setup.
The FT7 is an over-ear, open-back planar magnetic headphone built around a 106mm driver and a 1μm diaphragm. FiiO also specifies a 20Hz–40,000Hz frequency range and 25-ohm impedance. Those figures make the FT7 the more straightforward of these two options to consider for a broad range of wired listening setups, though the specs alone can’t guarantee how it will sound with any particular device.
Its carbon-fiber body and headband are listed at 427g, and the package includes genuine lambskin and breathable fabric ear pads. That gives you a practical choice between two pad materials instead of a single fixed feel. The cable is detachable, uses a 4.4mm balanced connector, and comes with two adapter plugs. Those details make the FT7 appealing if you value modularity and want options for connecting it to different audio equipment.

For flights, the key limitation is the open-back design. It won’t provide the cabin isolation people usually seek from travel headphones, and the listed noise control is passive rather than active. I’d skip the FT7 if your priority is blocking engine noise, taking calls in a noisy cabin, or packing a particularly light headphone. Its 427g weight is also substantially more than the ATH-R70X’s listed 7.41 ounces.
The Generic ATH-R70X is presented as an open-back reference headphone for mixing, mastering, and critical listening. Its listed frequency range is 5Hz–40kHz, and its driver is dynamic rather than planar magnetic. The aluminum honeycomb housings are intended to preserve the open-back design, while the breathable fabric ear pads and 3D wing support system are aimed at extended listening comfort.
At 7.41 ounces, it is the lighter option by a wide margin compared with the FT7’s stated 427g. It also has a 470-ohm impedance, a detail worth taking seriously when choosing a listening source. In practical terms, I’d think of this as a headphone for a desk or studio chain that can properly drive a high-impedance model, rather than as a plug-and-play travel pick. Its cable is wired, and the supplied information identifies a 3.5mm jack.
The ATH-R70X is the more suitable choice if your main goal is extended, open-back listening at home or in a workroom and low headphone weight matters. It is a poor match for anyone expecting a closed-off listening experience on a plane. The open construction admits surrounding sound, and there is no active noise cancelling feature listed. Its high impedance also makes source compatibility more important than it is for the FT7.
• Best for a planar magnetic design → FiiO FT7. It has a 106mm planar driver; the ATH-R70X uses a dynamic driver.
• Best for a lighter headphone → Generic ATH-R70X. Its listed weight is 7.41 ounces, compared with 427g for the FT7.
• Best for two ear-pad materials → FiiO FT7. It includes lambskin and breathable fabric options.
• Best for a high-impedance studio setup → Generic ATH-R70X. Its 470-ohm impedance makes source suitability an important part of the decision.
• Best for a detachable cable and adapter options → FiiO FT7. Its cable is detachable and includes two audio adapter plugs.
• Best for an open-back reference-listening brief → Generic ATH-R70X. Its design is specifically positioned around mixing, mastering, and critical listening.
• Best for flights → Neither, if noise isolation is the priority. Both are open-back, and neither lists active noise cancelling.
• Best if you want the lower listed impedance → FiiO FT7. It is specified at 25 ohms, versus 470 ohms for the ATH-R70X.
One travel-search distinction matters here: “best long battery life headband headphones for flights” points toward wireless headphones with a battery, but neither of these models lists a battery. The FT7’s connectivity information is inconsistent: it identifies a detachable cable and wired jack, while also listing Bluetooth. There is no battery-life figure, so I wouldn’t treat it as a proven long-battery-life travel option.
My Verdict
I would choose the FiiO FT7 for home listening if I wanted the planar design, pad choice, and detachable cable.
I’d choose the Generic ATH-R70X for a lighter reference headphone, provided my audio source suits its 470-ohm impedance.
For flights, I would not buy either expecting cabin-noise isolation: both are open-back.
My pick for flights is the FT7 only if open-back listening is a deliberate choice and I’m willing to accept the weight and surrounding noise.
Neither is designed to block cabin noise. Both have open-back designs, and neither lists active noise cancelling. If isolation is your priority, these specs don’t make either one a strong fit for a flight.
The connectivity details list Bluetooth, but also describe a detachable cable and a headphone jack. No battery or battery-life figure is provided, so there isn’t enough information to call it a long-battery-life headphone.
The FT7 is listed at 25 ohms, while the ATH-R70X is 470 ohms. That makes the FT7 the less demanding-looking option by impedance, although actual listening results depend on the source and its output.
The ATH-R70X is much lighter by the listed figures and has breathable fabric pads with a 3D wing support system. The FT7 offers two pad materials and a carbon-fiber build, but its stated weight is 427g. Personal fit can still vary.
