Crutchfield Customer Review (What's this?)

We ,a small congregation are enjoying this product in our chapel for some of our hearing impaired members .They are great and we are overjoyed to be able to hear from the pulpit, some of us for the first time. We contacted Crutchfield and explained our problem to Zac and he recommended these Headphones and transmitter and they work great. Thank you Crutchfield, and to Zac from the Rensselaer Branch of the Church of Jesus Crist of latter Day Saints In Rensselaer Indiana. Also thank's to the maker of these fine electronic miracles Sennheiser.

Crutchfield Customer Review (What's this?)

We love the headset we purchased. It was to replace the original headset we had for the wireless head phone my husband uses to watch television.. You see, he is hard of hearing and must have the sound on the TV up very high to hear anything. A friend whose husband had the same problem passed the set on to us after he passed away and it has been as life saving for me as it was for her. What is really neat is he can do other things (like the dishes) and not lose his place in his show because the headphones work in what ever room he is in. We really like it - it keeps peace in the family!!!

Thanks for your question. I'm sorry, no, there is no base included. On the main product page you can see what's in the box which is HDR-120 Wireless on-the-ear headset and 2 "AAA" Ni-MH rechargeable batteries (1.2V/600 mAh). For the base to be included you would have to purchase the RS 135-9 at the link below, hope this helps. https://www.crutchfield.com/p_143RS1359/Sennheiser-RS-135-9.html [ Kenny  Mar 17, 2017 ]  Staff
