"Frustration cable" but it does the job
on 28 July 2015
My girlfriend refers to this as 'frustration cable' due to the ridiculously long length, and inflexible nature. That aside, it seems to be reasonably well made, and it certainly functions as desired.
The actual operation for putting a Samsung Galaxy into dock mode is very simple, a single specific (420k iirc) resistor to pin 5 of the microusb, having several attempts at making my own connectors and failing to get a reliable audio signal, I bit the bullet and ordered the iBolt. At the time, it was the only premade docking cable available. 10 months on and I'm happy to say it's still working perfectly.
For a relatively expensive cable, it doesn't really have the feel of quality. The connectors are chunky and feel cheap, with untidy trimmings from the injection moulding. Nothing to worry about, they are solid, but it doesn't feel or look anything like a premium product. The cable itself is far too long for my needs, and I suspect most other peoples too. It is also very stiff and prone to retaining kinks/bends (of which there are many from the initial packaging, so don't think you can treat it carefully and be fine). There is no velcro tab or winder to hold any extra tidy, something which is worth adding if you don't plan on using the full length, or permanently routing it discretely behind your dash.
The excessively long length isn't just a cosmetic issue. The electronic effect of having a much longer cable than required is bad news for both charging and sound quality. It seems that most of the negative reviews are due to a ground loop, caused by the charging and audio sharing the same common ground. This will be evident as a high pitched whine while the engine is running. Easily remedied with the addition of a ground loop isolator. This isn't really any fault of the cable itself, a fact of basic electronics.
All in all, it works. And that's what's important. Having damaged the jack port of my Galaxy S4 active, this is now the only means of getting wired audio out of my phone.
