Sennheiser RS140 RF Wireless Headphones

I just got this set about 3 weeks ago and i love it. It fits around my ears very comfortable. I have owned some headsets that feel nice and comfy at first but after an hour or two they start to irritate my ears. I have worn the Sennheiser RS140 for over 12 hours straight without my ears feeling achy or sore in the slightest. As for battery life, for as long as I wear them (7-10hrs) I have never ran out of battery life. The nice features about the batteries for those that have plans to use their set a lot is the batteries are replaceable and can be found at any of your local drug stores. This wireless headset comes with comes with AAAx2 NiMH (Nickel Metal Hydride) batteries which are placed next to one of the speakers. Just turn one of the ear couplings and it comes off very easily. There are no wires behind the hear muff as it is all enclosed so you don't have to worry about damaging the speaker or connections when replacing the batteries. The recharge rate of this headset is about the same length as they were in use, so if you used them for 5hrs, it will take approximately 5hrs. to recharge.

As for the wireless part of the headset, it runs at a frequency of 900MHz so if you have any phones that run at this frequency, it could be a bit of a problem. Thankfully there are 3 different channels you can run them at. I noticed sometimes if you tilt your head forward you will get a bit of snow sound…tilt your head up and it goes away. Because of where I have my base located, it goes through lots of walls and I probably get more snow than most people will. This headset does not come with a power button for the base. Instead it turns on and off depending on if there is an audio signal going to the base. The headphones themselves have a large but not too large switch on the left ear piece on the behind that can easily be turned on/off with your thumb. If you turn the headphones on with the switch but there is no signal going to the base, it will remain off. Not sure if this is a disadvantage or not, but even if you are not using the headphones but a signal is being sent to the base, it remains on. The range of the headset is well within even a large house's distance. Placement of where the base is located has a lot to do with the reception you will get as is true with all wireless devices.

Now lets talk about sound quality. For a wireless headset, it's wonderful. It has rich base for those that like balanced music. I have used various headsets and a lot lack in the bass and mid ranges. Not these. In some instances on select songs, the base can be overwhelming a bit and overpowers the mid range sound frequencies. With 98% of your listening music it shouldn't be an issue. The headset claims that it enhances voices…from my experience it does. If you plan on using it for audio conversations, it is much easier to understand people than over regular speakers. Part of that though could be because of other noise cancellation design, it blocks out atmosphere sounds around you. Supposedly there is a built in feature that reduces hissing noise when no audio signal is being transmitted. I notice very little difference one way or another. There is always a low his that runs at low or no signal being transmitted, it just seems like it's a different frequency hiss but at the same volume level. The set has a feature that limits the volume of your incoming signal so that it doesn't blow your ear drums out. When listening to music and it has low spots, it increases the volume a little so you can better hear it. The manual calls this feature "Dynamic compression system". If you do not like this feature and what to hear your incoming audio in its purest form, it can be turned off by a switch in the bottom right of the base. Last but not least about the audio quality, there is a compression light that turns on or off pending on if its in use or not. It also has a second feature, for when it blinks slow, it is telling you that for optimal sound, your input level is too low and needs to be amplified a bit more. When the light is blinking too fast, it's telling you that you are sending a signal to the base that is too powerful and that you need to turn your output level into the headphones down.

The construction of the hear pads are like any other noise cancellation headset with foam (good thickness) covered in a thin material. I am not sure what kind it is but it doesn't get sticky against your skin when wet. I just know under all conditions and length of time, its comfortable. There are two sliders on the left and right side of the headset that are notched for lengthening and shortening the headset to fit your own head accordingly. The frame of the headset is plastic with foam on the inner part of the set giving you even more comfort. This foam is actually split into three different sections which you can not tell where it stops when its on your head. In between these three sections are two metal strips which is where the headset touches the base to recharge itself. The power switch as stated earlier is on the back left speaker. On the right, there are three options. One is balance, so you can adjust the volume coming out of each channel (good if you have hearing loss). The second is a Tune button which tunes into the correct frequency being sent from the base after you change it from one channel to another.

I only have a few words in reference to the manual. It's short and to the point. Within 74 pages they are able to include it in 9 the same content different languages. Each feature is explained in about two to three sentences. It would help if they included information about where the best location is to place the base, what the expected batter life is for different usages before they need to be replaced. At least it states all its features and what they do which is more than I can ask for from other companies.
Cost….they are worth every penny.

As i have an issue with earing out the pads, in the manual it lists model numbers for replacement pads along with additional headphones you can buy.

I paid $130 on the internet including shipping.
