Sennheiser D10 Phone Wireless Headset

The DA35 adapter is being used to adapt a headset mic (microdot) to my Sennheiser EW100 wireless system. The results have been excellent.

For years I had been using the older Sennheiser RS 120 wireless headset which operated in the 926-928 MHz frequency range. The performance was adequate, but the unit suffered from multipath cancellation (signal reduction due to the out of phase combination of multiple reflections). You will notice this when you move your head slightly, and there would be a sudden, and audible, change in signal amplitude or a short burst of background noise. As I had need for an addition system, I decided on the RS 175 as it seemed to have good reviews. I have not been disappointed. The RS 175 operates in the 2.4 GHz band with digital modulation. While 2.4 GHz systems are also subject to multipath propagation deterioration, I noticed none with this system, even with the headset taken outside onto the patio with the transmitter 40+ feet away. As typical with digital modulation systems, there was a threshold effect -- if the headset got out of range, the signal would abruptly disappear, quieting the audio -- in the past, you would simply be greeted with noise. In addition, I very much like the Bass Boost and Surround Sound options which can be quickly selected at the press of a button on the headset. The one negative for the headset is that you need to really take the headset off in order to figure out which button to press. I find this a rather minor inconvenience as I am not changing audio level, bass boost or surround sound options on the fly. In summary, Sennheiser did a superb job with this unit. The audio quality is excellent (I used an analog input -- an optical interface also exists for even better quality) and the annoying multipath effects so common with many wireless headsets are non-existent.

bought it so i could use my Sennheiser Game One headset with a chromebook or on my android phone, mic volume is spot on with this headset which is good considering the lack of mic volume adjustment available in those OSes, adapter included allows me to use it on PC also if my sound card goes out or is just acting out. volume of the output gets more than loud enough. The rocker on the side of the device adjusts the volume in the OS, its not internal hardware adjustments. easily worth the price. I didn't test the mute button since the headset I used has built in mute with mic boom being pushed up.

I spend alot of time on the phone being a Sales Professional and wish I would have pulled the trigger on a wireless office headset sooner in my career. I have been sufferring from severe neck pain for some time now and after about two weeks using this device the pain has reduced significantly. Although any wireless headset probably could have produced this same result I tested many other brands/models and this set hands down is the winner. This set works as advertised 300+ft from my desk.

Great multi device wireless headset. From desk phone, cell phone, to PC for Zoom, Skype.

This works with the Sennheiser HMD 26 headset and works well

I think sennheiser is the best wireless system

Sennheiser wireless is flawless. It never fails.

I use these for my sony & sennheiser wireless system.

This headset is very good for the price. I use it with my I-phone.
