Sennheiser RS 175 Reviews

Excellent sound quality, light weight, good range

By Erin
Rated 5 out of 5
Date: 2025-03-28

I'm happy that I chose these as my first set of wireless headphones! I am a sound quality snob and these are just right for me. I love the surround-sound setting and the bass options. The high quality sound lets me listen at a lower volume and still enjoy the beats while doing things around the house. The range covers my house and the garage as well, so doing chores and projects are a lot more fun! I like the angled shape of the earpieces also, they're very comfortable. They were true to the initial charging time stated and took about 16 hours. After that they last for hours and don't take very long to recharge, usually less than 30 minutes. I highly recommend them for ease of use and sound quality!

Very easy to use and sounds great

The RS 175 is extremely easy to use and sounds great. I hooked it up with my analog TV headphone out jack, and you can play the headphones by themselves, or at the same time as the optical digital TV out plays through the audio video amplifier into my corded speakers. That way if noisy people enter our living room I can just slip on the headphones and not have to ask them to be quiet or to leave, and I don't have to jack up the sound coming out of the speakers. Also, you just turn them on and they are automatically connected, you don't have to take any additional steps or try to debug any issues. The audio quality is very good and the headset is comfortable.

I want to use the RS 175 system to monitor the output of an analog mixer that is part of a home recording setup. How much latency can I expect between the time the signal appears at the mixer and the time it reaches the headphones? I can't find any specs on latency.
Asked by: Frank
there is no noticeable latency, as the RS 175 is designed for home entertainment system. They are optimized for Movies, TV and game playback and sound great. However that eq curve is not great for recording as it enhances bass response and dialogue. I would suggest one of Sennheiser's studio headphones for recording.

Can anyone compare the sound quality of the RS 175 to the Sennheiser HD 450BT wireless bluetooth headphones?
Asked by: Frank
After a search, I am not finding much differences in audio. The main difference between the 2 will be the Wireless Connectivity. The 450BT provides Bluetooth to connect wirelessly to any other Bluetooth capable device. The RS 175 operates on Radio Frequency (RF) that interacts wirelessly with the Base. You will need to connect your audio source to the Base to transmit audio to the packaged headphones.

Yamaha RX-a730 has a 3-port RCA type av out (video/left/right). Is this where i would connect the base unit?
Asked by: David
Yes, it should work. You would have to assign what audio goes out of the RCA connection if you have multiple sources you'd like to listen to.
