Question: Is this a stereo cable?
Document: commonly used stereo audio mini-cable. It works well for small hardware such as mp3 players and smart phones - to plug into the car stereo player and other uses.
Not sure if its the car stereo or this cable.Ive never had a deck make this buzzing noise every time I connect the mp3 player.Have tried other cables.Same thing.
Bought this thing thinking it would be a good little Aux cable for my car stereo. Boy was I wrong.1. wire quality is crap causing the audio quality to suck.2. the little wind up piece retracts itself randomly when you aren't touching it.3. wind up piece broke the 3rd day I had it, but that was only after I could only hear music when I held it at a certain position.totally cheap piece of trash.
This cable does NOT work for iPhone 3GS. I tried to connect my iPhone 3GS to my car's AUX port using this cable. It went into both ports, but I heard either no sound or a big noise from the car speakers. As I tried to adjust connection several times, sometimes music came out from the car speakers but it was not stereo but monaural. Apparently the metal connector part of this cable does not match the iPhone 3GS headphone port.
I got this item in the mail and it didn't even work at all with my stereo and iphone. Terrible purchase!
I can now plug my iPhone into my car stereo and get real stereophonic sound. Can Sham-Wow do that?
I`m using for my entertainment in home, and my cars, trucks, to connect to my stereo, tablet, phone, pc, and lap top.
Exactly what I expected, ship quickly, and works as it should. I'd buy it again. I like having my phone connected to my car stereo.
Item worked, I just did not anticipate how low quality the sound was going to be when I used the item to plug my phone into my car stereo.
Car audio cord works with my car and my stereo in my room it the right length for envy thing and nothing was wrong with it it works well.
Answer: It's an Auxiliary Cord. I connect it to my phone so that I can listen to music in my car.
