Question: Does the cable fit into the iphone 5 if the iphone has an Otterbox case on it?  I already have a cable where the connector is too fat.
Document: This makes it easier to run it into center compartments and other AUX port hiding places.3. Rugged feeling construction.4. The straight plug housing is slim enough to fit into an iPhone hard case.5. The right angle plug (not shown correctly on product page, so I have included one that I took in the user photos section.Overall, this is a "go to" cable buy.
I bought these to use with my iPhone 5S that is housed in a Speck Candy Shell case. When I upgraded my phone & got the case my previous aux cable would no longer fit the aux port. These are perfect and work very well. I would recommend.
The cable seems of good quality. I used the straight end on my iPhone 5 w/ a Speck Candyshell Grip case without issue. I'm sure this cable could be used with phone cases even with very narrow headphone openings. My only concern is the thickness of the cable. As another reviewer said, it isn't much bigger than a linguine noodle. I'll give the cable 5 stars and update later if something happens due to the thickness of the cable.
the 3ft is a bit short for me. But the loss of one star is because of the cheaper plastic enclosure of the right angle piece: the Beats cable has a flexible rubber right angle; the plastic of the Belkin is already breaking open after repeated pressure on the 1/8 inch gap between the right angle and the iphone case.
This cable just use it, When you fist impression , really looks nice . When connected got a lovely quality.I give it 5 stars over other many cables I tested with my Nissan Altima V6 Bose audio system AUX , Other failed due to quality and or connector size which cause the cable to pulled out by itself.
I keep my iPhone in a SPECK rubberized case (which is fantastic) and the  Belkin Right Angle Auxiliary Cable is the only aux cable I own that will plug in without peeling back the case.
This is a decent auxiliary cable for its purpose. I connect my iPhone to my car's auxiliary input, and the sound is very good (but then again, so was my 2 dollar cheapie cable). I like the right-angle plug for plugging into my iPhone. The 3 foot cable is a bit too short for my liking, but there is also a 6 foot version for a bit more. 5 stars for the function and feature.So what's not to love? Well, the price tag.
I don't know what genius decided that our new Mazda had to have a completely black interior, but they weren't doing any favors to those of us with middle-aged eyes (don't get me started on the heat in the middle of the Mojave Desert summer). Even my six-year-old can't find black items sitting on the black upholstery.It seems that every cable we need to use in the car is black. I already have a challenge finding the charger for my iPhone.
The angled design is perfect for my iPhone 5 and my car's aux port. The iPhone 5 has the audio jack at the bottom of the port. The problem is that I like to plug up the phone in my car and stick the phone in the cup holder. With the new iPhone design, it made the phone off-balance until I got this cord.
The right angle shape makes this more durable. In my case, I use this cable to connect my phone to the auxiliary audio jack in my car.
Answer: Yes it will. I have a 5s with an otter box defender and it fits.
