Sony MDR RF811RK body


The body of the Sony MDR RF811RK headphones is made of a very acceptable durable plastic. The materials are not fancy, but in this price range you can't always find the build quality of more expensive Bluetooth headsets. The package comes with the base/transmitter, power cable and Ni-Mh rechargeable batteries.

The fit is remarkable thanks to the self-adjusting headband. The structure is not foldable, and they are not outdoor headphones, but they are perfect for home use. You can wear them for hours without any discomfort, thanks to the generous pads on the cups.


The Sony MDR-RF811RK use radio frequency wireless technology that allows you to use them wirelessly within a range of up to 100 meters (provided there are no obstacles). RF connectivity is the best for a TV headset because of the range. In addition, you can connect two headsets simultaneously.

They come with a station or base that connects to the TV or your favorite device with a standard jack. Unlike other wireless headphones, they do not use Bluetooth connectivity. They are not as versatile since you need the base, but the RF connectivity doesn't suffer from interference. As we said, this technology is the best if you are looking for a headset to connect to a 4K TV.

Battery life

The batteries that come with the Sony MDR RF811RK headphones (others can be purchased separately) provide up to 16 hours of continuous playback at medium volumes. Capacity varies according to volume, but is very good for a cheap wireless headset.

Sound quality

These Sony headphones feature 40 mm neodymium drivers that deliver a rich and powerful sound. The closed design of the Sony MDR RF811RK minimizes external noise, helping you enjoy subtle details (which would otherwise be drowned out by ambient sounds).

They are very cheap headphones, and do not offer the sound quality or fidelity of the best HiFi headphones, of course. That said, the audio is very pleasant, and the power surprised us. Likewise, the connectivity is perfect, and you can use them with different audio sources, such as TVs, tablets, etc.

The quality of the connection and good isolation are two of the best features offered by the Sony MDR-RF811RK. This wouldn't matter so much if the sound didn't stand out, but it's actually remarkable for this price range. All frequencies are perceived as clear and rich, with good textures.

They are very affordable for the quality they offer in all departments. Connectivity works flawlessly, and you can select the channel or volume directly from the Sony MDR-RF811RK headphones.

The audio of these inexpensive headphones is very decent, as is the passive noise isolation. They are comfortable, have a good battery and the wireless range of 100 meters is unique. In this price range, it's difficult to find a better option.

Why don't we like them?

The build quality is not the best, and the sound is not the most subtle either. However, this is to be expected for such an affordable TV headset. On the other hand, they do not have Bluetooth connectivity. RF technology is perfect for the home, but it's not as versatile as Bluetooth.
