If you want wireless freedom and long listening sessions for mobile gaming, choose Sony RF400; if you need lightweight, wired headphones with an open, spacious presentation, choose Audio-Technica ATH-R50X. The Sony is designed around a TV transmitter, while the Audio-Technica is a straightforward wired headphone for a private listening space. For phone gaming, neither is a Bluetooth headset, so the connection you need matters as much as the sound design.
Sony RF400 vs Audio-Technica ATH-R50X at a Glance
• Audio-Technica ATH-R50X: Its open-back design and 207-gram construction favor spacious listening and lighter wear; the trade-off is a wired connection that does not isolate sound from the room.
• Choose the Sony for wireless TV listening and long sessions near home.
• Choose the ATH-R50X for wired listening in a quiet room, including audio work and focused music listening.
• For mobile gaming, consider your device’s headphone connection: neither model uses Bluetooth.
The Sony RF400 is an over-ear wireless headphone system built for listening from a television. Its included transmitter dock connects to a TV through an RCA audio output or headphone jack, then sends audio to the headphones over RF. Sony specifies a wireless range of up to 150 feet and up to 20 hours of battery life. That combination is useful when you want to move around at home without staying tethered to the TV.
It also has a closed-type design, a noise-reduction system, and 40 mm dynamic drivers. Those are relevant if you want a more contained listening setup for a show or game while others are nearby. The headphone’s comfort-focused ear pads and headband may suit extended sessions, while the transmitter-based arrangement avoids a cable running from the headphones to the television.

The Audio-Technica ATH-R50X is a wired, open-back headphone aimed at accurate listening and audio production. Its design emphasizes extended bass, clear midrange, quick response, and a wide, realistic soundstage. In practical terms, that open presentation may appeal to someone who prefers a less enclosed listening feel for music, editing, or studio work in a private space.
At 207 grams, it is a lightweight over-ear option. It comes with two detachable cables: one 3.0 meters long and one 1.2 meters long. Both connect at the left earcup with a twist-lock connector; the package also includes a 6.3 mm adapter and a carrying pouch. The shorter cable may be easier to manage at a desk or with a nearby device, while the longer one gives more room to move around a listening position.
That openness has a real trade-off: the ATH-R50X does not seal off the outside world. Sound can pass between the earcups and the room, so it is less suited to noisy surroundings or situations where you need to keep your audio private. It is also wired, not Bluetooth. For mobile gaming, it can work only if your device supports a compatible wired headphone connection. If you specifically want Bluetooth headphones for mobile gaming, this is not the feature set you are looking for.
• Best for wireless TV listening → Sony RF400. Its transmitter connects to a TV’s RCA output or headphone jack, with RF wireless audio to the headphones.
• Best for a long stated listening window → Sony RF400. Sony lists up to 20 hours of battery life, though the headphones need charging.
• Best for moving around at home → Sony RF400. Its specified wireless range is up to 150 feet, which gives it a clear advantage over a cable-bound design.
• Best for a spacious, open listening presentation → Audio-Technica ATH-R50X. Its open-back construction is intended to create a wide, realistic soundstage.
• Best for audio production in a private space → Audio-Technica ATH-R50X. Its design is positioned for mixing, mastering, and other demanding listening tasks.
• Best for lighter wired wear → Audio-Technica ATH-R50X. Its stated weight is 207 grams, and it includes two detachable cable lengths.
• Best for direct phone use without checking a wireless transmitter setup → neither by default. The Sony uses RF through its dock, and the Audio-Technica is wired; check your phone’s available audio connection before choosing.
• Best for blocking out more of the room → Sony RF400. Its closed-type design is the more suitable of these two for a contained listening experience, while the ATH-R50X’s open-back construction lets room sound in.
I would choose the Audio-Technica ATH-R50X for mobile gaming only if my phone supports its wired connection and I’m playing somewhere quiet. Its lightweight build and open presentation make more sense for a personal, stationary setup than a TV-focused transmitter system.
If wireless freedom at home is the priority, I’d choose the Sony RF400 instead—but for TV listening, not as a Bluetooth phone headset. For mobile gaming, my deciding factor is whether I want a compatible wired connection or a wireless setup built around a TV.
No. The Sony RF400 uses RF wireless technology and a transmitter dock, which connects to a TV through RCA audio out or a headphone jack. It is not described as a Bluetooth headphone.
It is a wired headphone with a 3.5 mm jack. You can use it with a gaming device that supports a compatible wired headphone connection, but the product information does not describe Bluetooth connectivity.
The Sony RF400’s closed-type design is the more contained option. The ATH-R50X is open-back, so it does not isolate you from room sound in the same way and may be less suitable where you need to keep audio to yourself.
The Sony specifies up to 20 hours of battery life and has comfort-focused ear pads and a headband. The ATH-R50X is lightweight at 207 grams and has a new headband design; its open-back construction may suit extended listening in a quiet space. Which feels more comfortable will depend on the listener.
