Question: Does it connect to a S/PDIF optical digital audio port?  "Toslink" cable included?  What are connections, what cables included?
Document: If your tv does not have audio out RCAs, you will need to buy a converter and digital audio coax or digital optical cable, approximately $50 in additional parts. Many TVs do not have RCA audio outs (only inputs), they have digital audio coax or optical outs, which Rocketfish does not support - it seems outdated to support only one method of connectivity when there are several more popular configurations.We have access to several different brands (Samsung, Hitachi, Phillips, Vizio) and none of them were able to hook up to the headphones.
I thought I was going crazy because I must have plugged the RCAs into every port on my TV, but these headphones will not hook up to either of our TVs. A digital optical cable or digital coaxial cable is needed to hook up to the TV - neither of which is supported by the Rocketfish headphones. Incredibly frustrating. I checked both my TV manufacturer's manual, as well as the Rocketfish website and - yep - they won't work with TVs that don't have RCA outputs.I did not bother with a converter as someone else mentioned, I just returned them citing incompatibility.
I did connect the RCA audio cable to our Directv genie box instead of directly into the tv, as suggested in the directions, because I could not get it to pair connected to the tv. The directions are very clear and understandable. I am amazed at the sound quality and clarity. I don't have to ask anymore, what did they say? I could actually hear the lowest speech in a musical background. I am also able to hear our surround sound through the headset. I feel like I am in a theater setting.
I will first detail the packaging/quality, then the actual sound of the headphones.First off, the package was fine, but the actual headphones were dusty (yes, dust!) and the cables and packaging looked like they were just tossed in there by a 4-year old. No ties or anything, just crumpled up and thrown in. The headphone and stand quality are thin plastic (I expected a little nicer for the price) and the button are kind of crappy. It does come with a RCA to RCA audio cable though.As for the sound quality, these aren't that bad.
I am very happy with the Rocketfish Wireless Headphones. Easy to setup, pairing worked automatically without a second thought on my part, and the set charged quickly. Some have complained that the charging mechanism is problematic. Not sure how that can be. The docking base includes two pins that match up to two large contacts on the left ear piece. Simply drop the headphones into the base and the charging light appears. I was pleasantly surprised that the base included output connections that pass through the audio content to an external amplifier.I use the headphones to watch/listen to TV while I exercise, and was worried that headphones would not stay put.
So far they work as they should. *Standard connections on the stand are RCA In/Out. No 3.5mm or 1/8&#34; or anything else. Keep that in mind if connecting other peripherals. You'll need adapter cables.
Easy to set up. I set my TV's "Audio Settings" control so that the audio output is not affected by the TV's remote control. Now I can listen at a comfortable volume for me while the rest of the family can set the speaker volume to their preference.No longer do I have to choose between missing half of what people are saying or turning the TV volume up so loud it is irritating to others in the room.Easy to set up, easy to use. Plug in the AC adapter, connect the TV's audio output, turn it on and in about 30 seconds the transmitter connects to the receiver.
If you are looking fore wireless this is the best I have experienced. The volume control is easy to use, as you simply press up or down on the right side, and charging is easy. Besides sound quality I have a few more complaints. One is that the unit must be on to charge. Another would be that they really skimped when they give you cables for this. They gave a 6 ft rca to rca witha 1 ft rca (female) to 3.5mm. basically a way to convert the cable to 3.5mm.
I was hoping for 2 discrete cables. Lastly I should note that these are more comfortable.
I am a little hard of hearing--not deaf. I don't need a hearing aid. But I like the TV volume at about 32, while the others in my house like it at about 24. I bought the Rocketfish digital headphones and the problem is solved. I can set the TV volume at 24, put on the headphones and adjust the volume to my liking. The headphones have the additional advantage of shutting out ambient background noise. Let the grandkids cry--no problems here. I have never sent a review before about any products.
Answer: No. RCA connection only, as far as I know.
