If you want wired, open-back planar headphones with a straightforward setup, choose Avantone Pro Planar Headphones; if you need a more connection-flexible package with detailed driver and cable specifications, choose FiiO FT5. For the “for kids bluetooth” search, neither is a Bluetooth pick: both are wired, open-back headphones aimed at adult listening.
• Avantone Pro Planar Headphones: Open-back planar design, detachable cable, and a stated 30Hz–30kHz frequency range; the trade-off is a wired-only setup with no noise control.
• FiiO FT5: 90mm planar drivers, a stated 7Hz–40kHz frequency range, and swappable audio plugs; the trade-off is that its open-back design also offers no noise control.
• Choose Avantone if you want a relatively simple wired headphone for focused listening or audio work.
• Choose FiiO if you want multiple connection options and the included adapters and earpad choices.
• Neither is the best fit for a child specifically seeking Bluetooth, or for someone who needs sound isolation.
Avantone’s appeal starts with its combination of open-back construction and planar magnetic drivers. The listed frequency range is 30Hz to 30kHz, and the headphones use a wired 3.5mm connection. That makes the setup uncomplicated: connect the cable to a compatible source and listen. The cable is detachable, so it can be separated from the headphones rather than remaining permanently fixed.
The open-back design is the central consideration. It suits a listening space where sound can travel out from the headphones and surrounding sound can reach the listener. That can make sense for stationary listening, music work, or a quiet room at home. The product description positions the headphones for musicians, engineers, content creators, and hi-fi listeners, but the spec sheet doesn’t establish that they are suitable for every studio setup or every source device. Check that your intended equipment has a compatible 3.5mm output.
The listed bundle includes a red carrying bag, and the headphones are described as over-ear, with metal and plastic enclosure materials. Those details make this the more straightforward option of the two on paper: there is no list of interchangeable plugs or alternate earpads to sort through. Its stated 3.5-pound item weight is worth considering if you plan to carry it regularly; that figure may include packaging or other included items, so it should not be treated as a precise worn weight.

FiiO’s FT5 is also an open-back planar headphone, but its specification sheet gives more detail about the driver and connection setup. It lists a 90mm planar magnetic driver, a 7Hz–40kHz frequency response, and a 36-ohm impedance. The stated sensitivity figures are 110dB/1Vrms at 1kHz and 96dB/mW at 1kHz. Those numbers provide useful reference points when checking compatibility with a source, although they do not guarantee a particular listening level or sound quality in every setup.
The FT5’s connection package is its practical differentiator. It includes interchangeable 3.5mm and 4.4mm plugs, with the 4.4mm plug pre-installed, plus a 6.35mm-to-3.5mm adapter and an XLR-4-to-4.4mm balanced adapter. The headphone end of its cable uses dual 3.5mm plugs. This gives a buyer more options for connecting to compatible equipment than the Avantone’s listed 3.5mm connection, but it also means checking what the source actually supports before choosing a plug or adapter.
Comfort and fit involve more than a single construction claim. FiiO describes the build as lightweight magnesium alloy, and the package includes protein-leather and suede earpad pairs, with the suede pads pre-installed. That gives the buyer a choice of pad material rather than one fixed option. The product listing also gives an item weight of 1.91kg; because that is an item detail and may refer to the packaged product, it is not a dependable measure of how heavy the headphones feel when worn.
Who should skip it: Skip the FT5 if you want wireless listening, need closed-back isolation, or would rather avoid choosing among several included connection options.
• Best for a simple 3.5mm wired setup → Avantone Pro Planar Headphones. Its listed connection is a 3.5mm jack, and the cable detaches from the headphones.
• Best for more plug choices → FiiO FT5. It includes interchangeable 3.5mm and 4.4mm plugs, plus adapters for other listed connection types.
• Best if a broad stated frequency range matters to your comparison → FiiO FT5. Its listed range is 7Hz–40kHz, compared with Avantone’s 30Hz–30kHz. A wider specification alone does not establish which headphone will sound better to you.
• Best for a detachable cable → Avantone Pro Planar Headphones. Detachability is explicitly listed for Avantone; FiiO’s data instead details its cable material and connector arrangement.
• Best for trying different included earpads → FiiO FT5. It comes with protein-leather and suede options, with the suede pair pre-installed.
• Best for an included carrying bag → Avantone Pro Planar Headphones. Its listed accessories include a red carrying bag; FiiO’s package lists a leather storage case and a velvet bag.
• Best for a child who specifically wants Bluetooth → Neither. Both are wired, open-back designs, and neither data sheet lists Bluetooth.
• Best for a quiet commute or noisy surroundings → Neither. Both list no noise control, and their open-back designs do not offer the isolation some listeners need.
Buying Considerations
Next, match the cable to your equipment. Avantone lists a 3.5mm connection and a detachable cable. FiiO provides several plug and adapter options, but those are only useful if they match your source and intended connection. If you are comparing headphones for a laptop, confirm which audio output you plan to use rather than assuming every adapter is needed or compatible with every device.
That matters for searches such as “best long battery life open ear headphones for laptop.” Neither product has a listed battery or Bluetooth connection, so battery life is not a meaningful point of comparison here. They are wired headphones, and “open-ear” is not the same as open-back: these models have over-ear cups and open-back designs.
The same distinction applies to searches like “headphone for fishing” or “neckband headphones for yoga.” Neither sheet lists a neckband, water resistance, or wireless operation. A wired over-ear headphone may not suit the movement or surroundings those activities involve. For those needs, look for products whose specifications explicitly address wireless use, fit, and exposure to moisture rather than treating either of these as an activity-specific option.
Finally, weigh accessory flexibility against simplicity. Avantone’s listed package is more pared down, with a detachable cable and carrying bag. FiiO’s bundle includes additional plug and pad choices, along with a storage case and velvet bag. More included accessories can be useful, but they do not automatically make a headphone the better choice if you only need a basic connection. If price affects your decision, check the current price on Amazon using the page’s button; no price comparison is stated here.
I would choose the FiiO FT5 for its wider connection options and included earpad alternatives, provided my audio source supports the intended plug. Avantone is the simpler fit if a detachable cable and 3.5mm connection are all I need. For “for kids bluetooth,” I would choose neither: both are wired, open-back products, not Bluetooth headphones. My pick is the FT5 for a flexible home listening setup, not for isolation or wireless use.
FAQ
Either may work if the laptop has a compatible audio connection, but the sheets do not specify laptop compatibility. Avantone lists a 3.5mm connection, while FiiO includes 3.5mm and 4.4mm plugs and additional adapters. Check your laptop’s output before deciding.
Neither lists noise control, and both use open-back designs. They are not the right comparison if your priority is isolating yourself from a noisy room or keeping sound contained around other people.
Avantone lists a detachable cable and a carrying bag. FiiO lists multiple plug and adapter options, two earpad materials, a leather case, and a velvet bag. The better package is the one that matches your equipment and how you plan to store or wear the headphones.
