Strength:

Wireless, comfortable, good range

Weakness:

Uses expensive, non-standard battery

I set out to buy a wireless headphone set that cost less than $150. I tested headphones from Advent and JVC in addtion to the Sennheisers, and the Senns sounded the best. Wireless headphones do not sound as good as those with wires. The RS-4s are a little muddy in midrange and could use a little bit more bass. For the price, however, they are the best of class. If you are an audiophile, buy wired headphones or buy a $300 wireless set. If you just want to listen to music while you are moving around doing other things, then buy these. I have no problems with their range, my set comes through loud and clear everywhere in my house. In sum, I'm happy with my purchase.

Where it counts:sound quality

I bought this headphone based on the Sennheiser reputation and wanting to be able to listen to quality music in a private cordless manner.
It was impossible to get any acceptable sound quality by tuning to the transmitter.
Sound was weak, distorted and with a lot of hiss, regardless which of the 3 channels I used.
I also started receiving music from somewhere else on 2 of the channels.
Ihis is in my opinion complete garbage, I knew not to expect the great quality that I get from my Beyer Dynamic DT990 normal headphone, but didn't expect this terrible sound quality.
I immediatly returned it the next day and got a refund without a problem.
I will never buy a cordless headset again.

Strength:

Price, No Cables, Good Sound Quality, Good Bass, Excellent Range.

Weakness:

Slight Hiss, Battery only 3.5 hours, No Stand for Reciever.

I tested a few other wireless Headphones in the range of $80 to $150. The Advent AW770, Sony MDR-RF930K and JVC HA-300RF The RS4-9's are by far the best sounding of the bunch.
The sound is clear and strong, with good bass. The range on them are up to 300' and I have no problem getting to about 250 of those feet. They start to break up at that point and as you keep walking, but it's still a great distance. Lets not forget about the convience of no cords. My wife is in no way interested in A/V, but she loves the hell out of these... No wires in the way, she can listen anywhere she wants and very easy for her to use.
My main problem with the RS4-9's is the battery life. Although there are two battery chargers on the transmitter the life is only 3.5 hours. Terrible if you only have one battery. You will need to an extra one. Personally I would recommend both, because it takes 9 hours to recharge a fully depleted battery. So if you have all three you have a fully rotatible battery system. Extra batteries are $19.99 and only Sennheiser batteries can be used.
There is a hiss on these H/P's which is not really that bad, and can be mad minimal with a combination of your source volume and the H/P reciever volume. First turn down the volume on the H/P's then turn up the volume on your source then adjust the volume on the H/P's accordingly.
Sennheiser really should have supplied a stand to rest the H/P when not in use. So you put them back where they belong when your finnished using them and so you don't have to lay them on different surfaces.
Overall, I love the RS4-9's. They are very lightweight and comfortable. They sound very good and i would definatly recommend them to anyone. I would also recommend getting them from JandR.com. I paid $69.99 for mine and All of the others I tested are under $100. Great prices JandR, Well Done...

everything possible

The only thing worse than wasting my money on these headphones,is the place i bought these from (PALM AUDIO VIDEO,DESTIN FLORIDA). I have spent thousands there but they will not get another dime from me.Had these a week would not even give me a store credit.I have other sennheiser headphones that are great but do not shop there or buy these RS40's.

Sennheiser is a true and dependable namebrand and that's why I purchased these 900mhz wireless headphones (400mhz in Europe). Expecting them to sound much like their HD counterparts, I was totally disappointed! You have to manually tune the headphones in like an AM/FM radiostation and then the headphones aren't nearly as comfortable as the HD series. Still to this day I can never seem to tune the headphones to match the transmitter properly! Sennheiser claims coverage up to 150'. How about more like 150mm or even 150nm. Now I'm not trying to dog Sennheiser but this has got to be their worst product ever produced! Stay away from the RS4-9 wireless headphones at all cost!!

I don't know why people expect 900MHz headphones to sound like their wired counterparts. I've tried other 900MHz headphones in this price range, and these are by far the best. If you want better, buy the 6s or the 8s. If you want audiophile quality, deal with the wire and purchase a set of HD 600s or Stax Lambda Nova Signatures.
