4.0 out of 5 stars Worth the price, June 4, 2004
By Driver Ed (Goldens Bridge, NY (USA)) - See all my reviews
This review is from: Sony MDR-IF240RK Wireless Headphone System (Electronics)
This review is on the Sony MDR-IF240R not MDR-IF240RK, not sure if there's any difference. I needed a wireless headphone for the bedroom because I watch TV over 2 hours every night while my wife sleeps and about 2 hours early in the morning. I've also owned a wireless Sennheiser HDR60 and a wired Panasonic RP-HT970 Vibration Series Headphone. The Sennheiser worked fine, but their rechargeable battery (two included) would only last me about two days. I always had one recharging so I could swap it out, but it was still annoying to have it cut out in the middle of a program. After a year one of the batteries wouldn't hold a charge any more and when I saw how much a replacement battery cost, I decided to buy the Panasonic. Because it was wired, the Panasonic RP-HT970 sounded great, especially the bass effects with DVD's. It was very comfortable and I would still be using it, if I hadn't tripped on the cable and broke it. It had also been an obstacle for my wife when she had to walk across the room.

I decided to go wireless again and bought the Sony MDR-IF240R after reading reviews. I wanted a headphone that used standard batteries and wouldn't need constant replacing. I have cordless phones and a wireless PC network, so I decided having no interference using infrared was better than having the ability to go room to room using other technology. Since I only used it for TV viewing, I was willing to accept decent, if not great, sound quality. This headphone met all my requirements. I put in one standard AAA battery instead of the rechargeable battery that came with it and I haven't had to change it in over two weeks of constant use (4 hours/day).

The headphones are mostly plastic and look a bit cheap. They are fairly comfortable, but if I tilt my head, they will fall off because the foam cushions are flat rather than cupped like the Sennheiser and the headband is rather flimsy. That would be my biggest complaint. Sony should also have provided a longer cable for the transmitter to allow more flexibility in placement. Sound quality is fine for TV viewing, but it can't compare to the quality of a wired headphone like the Panasonic which makes you feel like you're actually in a movie when played on DVD.

I have perfect reception using it at 12 feet and I've walked 45 degrees to the left and right without any loss. If something comes between the headphone and the transmitter, it will cut out, so positioning is very important. You can eliminate the hiss that others have mentioned, if you turn up the volume on the sound source (e.g. TV or Receiver) rather than turning up the volume control on the headphone. On the Sennheiser there was a tuning control, which I had to fiddle with in order to receive a signal, but the Sony doesn't have or need one.

In conclusion, this headphone met all my expectations, the price was reasonable and I would recommend it to others until someone comes out without something that has better sound quality and excellent battery life.

Sound quality - 4 stars (compared to other wireless)
Battery life - 5 stars
Range - 4 stars
Comfort - 4 stars
Fit and finish - 3 stars
Price - 4 stars

3.0 out of 5 stars Okay for tv, games, nok for music, January 2, 2004
By kyamadaret (Honolulu, HI USA) - See all my reviews
This review is from: Sony MDR-IF240RK Wireless Headphone System (Electronics)
These wireless headphones perform as advertised. Almost. I don't quite get the "24 feet" range but then again all the range I needed and expected was within a standard sized room. The convenience is freedom of movement within the room with decent fidelity to watch late night television or play computer games without distracting others. However the phones have a noticable hiss which is distracting for most music. Also a minor peeve is the plastic bar across the top. The bar is not padded and the phones have built-in springs which force the bar down on the top of your head. Noticably uncomforable for me after a while and I have a full head of hair. The comfort level is okay if you wear the phones draped along the back of your neck (which makes it tough to sit back in a high backed chair or lie down on the couch) or below your jaw (which makes it tough to munch on snacks in that position though). Or you can kludge it to a certain length with some electrical tape. Overall the phones are okay given the price. Just be sure that your expectations match what you are paying. If you want high fidelity and comfort and range, you will be better off paying up for another model.

5.0 out of 5 stars Great for TV watching; wish I'd ordered them sooner, April 7, 2006
By Aaron Contorer (San Diego, USA) - See all my reviews

Amazon Verified Purchase(What's this?)
This review is from: Sony MDR-IF240RK Wireless Headphone System (Electronics)
These headphones are clearly not intended for listening to music at high quality. But I have been using them to listen to my TV, and am delighted with the ease of setup, ease of use, long battery life, and apparent immunity from interference.

You can't use them outside the room, and the sound quality is good but not great. Perfect for TV. Even if obstacles partly block the infrared path, the sound continues uninterrupted. The headphones are comfortable and light, and run for many hours before recharging.

I am totally satisfied with the product, and only wish I had ordered something like this years ago!
