Sony MDR-IF240RK Review


Go wireless with your music

Wireless signal connection for cord free and uninterruptible sound transmission ; 24 ft. wireless range from the headset to the transmitter ; Light weight and durable ; Open air design ; Rechargeable battery that recharges when placed on the...

Some users have reported some hiss and static type noises, but this has not been confirmed as an outstanding issue ; As with all rechargeable batteries, they become worn over time and begin to lose charge

Check the Amazon website here for more information on this product.

Not that kinda $ good


I picked up these same headphones at a brick and mortar for like 60 bucks on clearance. After using them for a year though I could never see myself spending 250 on these. They are just not worth that kind of money. If you can pick them up on a huge...

Sound quality is just OK. The battery life is good

NO noise reduction because of the fact that they do not cover your ear completely. Not worth 250 at all

Proper set up


These do exactly what I wanted., a way to watch TV late at night when I get home from work without disturbing the household. I had hissing until I figured out how to set them up. Plug them into the earphone jack. This turns off the TV speakers and just...

very good sound once set up properly, comfortable

Foam ear covers come off easily, can't walk away and still get reception

Consumer review by:



for the price cant beat it.

got this for my older uncle. they fit perfect. the cushions are nice and soft. the headphones are incredibly loud and it comes with rechargeable batteries

if you loose the line of sight there goes your sound

They work


I originally bought them for my father so he could blast his tv's volume without disturbing his neighbor (he's in a nursing home). Then I find out he doesn't want anything on his ears so I took it home and I'm using it. Have to remember to unplug it...

They work well enough

When you put them on max volume you get buzzing

Consumer review by:

Just what I needed


This is perfect. It's got the volume on the headset itself, and that's pretty convenient, easy to hook up, long battery life, etc. The only downside for me so far is that when I go to use the bathroom and it loses connection with its stand, all you...

Lightweight, comfortable, and cheap

When signal is lost all you hear is static which drives me insane

Consumer review by:

Great Value


I second jhjr4 in that the other reviewers don't understand audio equipment. Turn up your source volume to max (or near it) and then slowly turn up your headset. Be careful not to unplug the headphone jack otherwise you'll wake up the neighborhood with...

Comfortable, Solid Sound, Rechargeable Battery

IR doesn't allow walking around, ear cushions fall off easily

Consumer review by:

Please read this before all negative reviews


People that are complaining about hissing and cracking need to learn how to setup stereo equipment before running to their computer and writing negative reviews. Turn up your source audio close to max and then gradually turn up your headset volume.....

Educate yourself on how to setup equipment

Great value. $38 on amazon, free shipping

Do not buy, they are unusable


Do not buy these, they are unusable, they make an extremely loud an irritating hissing and crackling noise, while barely being able to hear the actual sound they are meant to be playing. Absolute waste of money, if their were 0 stars, that's what I...


They make an unbearable hissing and crackling sound, even within a cm of the transmitter

Consumer review by:

A Waste of Money


I got these with the express purpose of enjoying TV while exercising. The amount of extra hiss & static was unbearable when on the treadmill . . . an absolute waste of money.
