The Sennheiser RS 175 is a set of wireless headphones intended for home use that offer excellent range and thunderous bass. With it on, you get some serious added thump out of the drums that will excite bass fiends but not purists. If you need the speakers active so others can be enjoying the same audio we recommend connecting your Assistive Listening System to the audio outputs (ie: RCA, optical output, digital audio out, etc) of the audio component. If the above solution does not resolve the issue it may be a situation where the wireless environment is too crowded and the multiple wireless signals keep butting up against each other and causing issues. - RS 185 - Uses rechargeable batteries and will automatically tune to the transmitter once set up. The hub will then provide outputs to run audio to the TV and audio to the headphones as well. A good quality digital to analog decoder is the OREI DA 34. Download. If the digital optical output is already being used by a device like a sound bar you will want the J-TECHDigital to Analog Decoder because it offers both an analog output for the headphones to use and an optical output for the soundbar (or other device) to use. If you need the speakers active so others can be enjoying the same audio we recommend connecting your headphones to the audio outputs (ie: RCA outputs, digital optical audio output, digital coaxial audio out, etc) of the audio component rather than the headphone output.

You will not lose audio quality as the digital signal is a carrier signal only. I'm rarely a fan of surround effects on stereo headphones for the simple reason that they rarely work well with stereo mixes, but I'm a much bigger fan of ones that can be turned off. Can I use wireless headphones for performance applications or music practice? A connection to the headphone jack of any audio component (ie: TV, A/V receiver, computer, etc) will automatically disable the speakers. I had no problem walking into different rooms of my apartment, closing the door, and receiving audio with no disruption. The RS 175's digital transmission quality, which uses frequency modulation over 2.4-2.8GHz to transmit audio fed to the charging base to the headphones, is nearly flawless, and it's easy to forget you're listening to wireless headphones. Most of the time the two signals are away from each other and there is no issue. You can purchase the adapter from Amazon.com, please see link below: RCA "Y" connector (Needed for RS 165, 175, 195). Contributing Editor Tim Gideon has been writing for PCMag since 2006. DirecTV Genie Client boxes offers a non-traditional audio output that requires a special connector that you can get two ways, http://www.amazon.com/Directv-Dtv-Pin-Composite-Only/dp/B00BDXBBJ2/ref=sr_1_1?ie=UTF8&qid=1447776467&sr=8-1&keywords=10+pin+adapter, http://www.amazon.com/Hosa-GRA101-RCA-Female-Coupler/dp/B000068O40/ref=sr_1_3?ie=UTF8&qid=1447777048&sr=8-3&keywords=rca+couplers, http://www.amazon.com/dp/B009Q88W0W?psc=1a. The cradle for the RS 175 recharges the batteries through contacts on the headband's underside; when the headband rests atop the charging dock, it begins charging automatically. The wireless range is up to 100 feet. For example if you take a set of headphones from one system (like the HDR 180 headphones from the RS 180 system) and pair it with a different system (like the RS 170) the headphones will provide audio however the headphones will not have the additional features (like Surround Sound) because the headphones do not have the supporting internal electronics. Radio Frequency signals have the ability to pass through most obstacles (like walls). Why do I experience Static/Hum/Hiss when using an Infrared Assistive Listening System? typically use an advanced digital audio signal such as HDMI or advanced Dolby audio. Our expert industry analysis and practical solutions help you make better buying decisions and get more from technology. Sennheiser headphones come in a range of styles including in-ear and on-ear versions. Many of the older wireless headphones manufactured by Sennheiser were designed before the digital/optical connection became as common as it is today and up until quite recently most audio devices had both RCA outputs and digital/optical outputs hence the headphones were able to be connected directly. The WiFi router will "see" the signal of the headphones and establish it's own signal in a different part of the bandwidth and the two devices will work without interfering with each other. What’s more, the innovative digital wireless technology ensures that signal transmission remains clear and accurate as you move from room to room. 2) If a set top box (cable box, DVR, etc) is in use look for audio output jacks on this device and connect the headphones to the set top box to allow for independent operation of TV speakers and headphones and hence the TV volume can be turned down or muted. The home theater-focused wireless headphones category is, compared with the larger realm of Bluetooth headphones, a niche market. The RS 175 sounds very bright and at times a little thin without Bass mode activated. The resolution is to call the cable company and request that the audio signal is reset. Features a selectable Bass Boost and Surround Sound options. Leave the system disconnected from power and the batteries out of the headset for 15 minutes. The wireless range is up to 360 feet. If it's a more mobile wireless experience you're after, the Harman Kardon BT, the Harman Kardon Soho Wireless ($95.50 at Amazon) , and the AKG K845BT ( at Amazon) are all comparably priced Bluetooth options with excellent sound. Dampen the Din: Bose Noise Cancelling Headphones 700 vs. QuietComfort 35 II. Features an AROUND THE EAR closed ear cup design that will block out ambient sound. Uses Radio Frequency (RF) technology to transmit the audio. First time purchase with Sennheiser and will purchase more in the future. It is not possible to retrofit older Sennheiser models to have a digital audio input as the internal electronics are designed for an analog connection/signal not a digital connection/signal. The Sennheiser RS 175, RS 185 and RS 195 Wireless Headphones have the ability to connect directly to a digital optical output that is outputting a PCM signal. So, if you're all thumbs, you might want to make sure the cradle is placed out of the way. The different wireless headphone models utilize different signal transmission technologies so the compatibility and interchangeability of the different wireless headphone models is dependent on the specific wireless headphone models in question. NOTE: A couple of the versions of the Digital to Analog Decoder are as follows: - GEFEN Digital Audio Decoder (http://www.amazon.com/Gefen-GTV-DD-2-AA- Digital-Audio-Decoder/dp/B0021QBIBQ/ref=sr_1_2?ie=UTF8&qid=1393427713&sr=8-2&keywords=GEFEN+digital+to+analog+decoder), - OREI Digital to Analog Audio Decoder (http://www.amazon.com/Orei-DA34-Digital-5-1-Channel-Headphone/dp/B008EPW7O0/ref=sr_1_2?ie=UTF8&qid=1393427822&sr=8-2&keywords=OREI+da+34). It's great all around. The headphones run on two included rechargeable AAA batteries, with one hidden behind the twist-off earpads of each earcup. Additional features include a a left/right balance control (ie: individual volume for each ear) and a speech intelligibility circuit to make spoken word much easier to understand. Radio Frequency is a type of wireless signal. NOTE: In some instances an adapter or extra component will be needed to make the appropriate connection. To overcome latency issues sometimes the component that the headphones are connected into will have a latency adjustment which can be used to adjust the component to match up with the headphones. Features an ON EAR "Open-Aire" ear cup design for hyper realistic sound however ambient sound will pass into the headphone too. Usually the delay (even at the 45 m/s level) is not discernible and hence goes unnoticed. The effective wireless signal transmission range (ie: how far the headphones can get from the transmitter) will vary from product to product and is determined by the type of wireless transmission signal being used by the individual wireless headphone system. Please bear in mind that we recommend these specific devices because we have tested them and know that they work. These will include transmitter/charging station, headphones, power cable, audio cable, batteries and adapters.Step 2: Insert the batteries into the headphones. He specializes in reviewing audio products, and is obsessed with headphones, speakers, and recording gear. The Bass Boost and Surround Sound listening modes will allow you to experience your home entertainment system like never before – the former increases the audio bass response while the two virtual surround modes offer a more spatial and livelier stereo sound. These plastic caps are only there to protect the connectors before use. Uses a digital signal to transmit the audio. The Bass Boost and Sur- Uses Radio Frequency (RF) technology to transmit the audio. The transmission strength is also solid; Sennheiser estimates the range at roughly 330 feet, which is both insanely good and very hard to confirm in New York City.
