The adapter is ok. At the processing can not be faulted. Shortcoming, however, is that you can not let the adapter to the equipment, as it will not function properly. You have to connect the adapter each time only on the iPhone and then connect only to the device. This is a bit annoying. But in any case it is a cheaper alternative than now thanks to the Lightning-connection of the new iPhones to get to the same new hi-fi equipment, radios or anything.
