5.0 out of 5 stars I live for wireless, December 30, 2000

By A Customer

This review is from: Sennheiser RS40 HiFi Wireless Supra-Aural Headphone (Electronics)

If you're going for audiophile quality sound, then these probably aren't for you. If you want a convenient wireless headphone system to watch TV or casually listen to music while moving about the house, then these are great. The sound quality is comparable to most inexpensive corded headphones and these sound better than other wireless headphones I've tried. They're light and comfortable and you just stick them back into the base to recharge. Supposedly the batteries last 4 hours per charge, but I've never tested that. The base features a slot to charge an additional battery (that can be purchased ...) and you can swap batteries quite easily.

This model has 3 frequencies that you can choose from by pressing a button on the base. If you have two of these, then you can use them both by leaving the bases on different frequencies. The headsets can then be tuned to either frequency (so both headsets can be tuned to listen to the same base signal). Unlike a cordless phone, where the handset switches frequency channels simultaneouly with the base station, this headset requires you to tune the headset to the frequency of the base station. This isn't hard at all, but this might explain why that other reviewer couldn't get a signal out of this (so read the manual). Along with the tuning dial, the headset also has a volume dial built-in.

I don't know what the guy from San Francisco did, but he is mistaken about the Sennheiser RS40's. They are a great wireless headphone. I get great sound throughout my home (even through walls). They are light and easy to use. I think SF just hooked them up wrong. These headphones are very very good. Try them if you're interested in good sound and light weight.

I was in the market for wireless headphones since I recently moved into a condo. I was all set to buy an inexpensive set of wireless Jensen headphones at a local CompUSA for $.... Well the reviews on Amazon were pretty unanimous, don't waste your money, and spend a little more to get either the Advent or the Sennheiser RF wireless headphones. I liked the style of the Sennheiser built in charger better and the reviews were a tad better. So I followed the reviews here and I am totally satisfied.

There are multiple jacks so I've hooked them into my Motorola Digital Cable box RCA jacks and I am thrilled with the quality. I can move from room to room with no interference whatsover. Someone here said they had trouble adjusting the frequency, I found it to be a breeze. I bought an extra battery since it can charge a spare. This is a five star unit if you are looking for good TV quality sound. It's not studio, but you aren't paying for studio quality. This is a great buy. And Amazon treated my order VERY professionally. Emailed me on the ship date, and gave me a UPS tracking number. I got it in 4 business days. I'm glad I looked here first. Thanks everybody!
