The Sennheiser RS 175 have the same look and build quality as the RS 165, but for critical listening, they sound a bit worse. They don’t do as well with voices and instruments, and there’s a bit too much bass. Also, they aren’t flexible enough to be used anywhere but inside with a clear line of sight to the transmitter. They are comfortable and have low latency, which is good for watching movies.
The all-black design of the Sennheiser RS 175 is sleek and simple. The over-ear earpads are comfortable and well-padded, but the padding on the headband, which is split into two parts to make room for the charging port, can put a bit too much pressure on the head after a long time of listening.

Where to buy Sennheiser RS 175 RF Wireless Headphone?
On the outside of the right earcup, there are controls for turning the volume up and down and for changing the Bass mode and Surround settings (more on those in the next section). Along the side of each earcup is a Power button and an indicator LED. When you turn on the headphones, an indicator on the charging cradle/transmitter also lights up.
The headphones run on two rechargeable AAA batteries that come with the set. One of the batteries is hidden behind the earpads of each earcup, which twist off. The cradle for the RS 175 recharges the batteries through contacts on the underside of the headband. When the headband is placed on the charging dock, it automatically starts charging. Sennheiser says the battery life is up to 18 hours, but a lot will depend on how loudly you play your music.
The cradle/transmitter is neither ugly nor a beautiful piece of design. It’s a functional tower that stands up and holds the headphones. On the front panel, there are buttons for Surround and Bass modes and an LED that shows the current status. On the back, there is an optical input for digital audio from your home theatre system and a 3.5mm analogue input for sources like a computer or mobile device.
You can choose between the two inputs with a switch on the back panel. Cables for both inputs are included, but the 3.5mm cable’s connector might be too big for your phone or tablet case. The only thing I don’t like about how the cradle is made is that it’s pretty light and seems easy to knock over, even though the base is shaped to keep it stable. The Sennheiser HDR RS 175 could be just what you need if you want to find a great way to get the most out of your movies without bothering your neighbours.
