This is from the company President. It's nice to know he's taking this seriously. He also brings up some valid points regarding the dimensional tolarances of plugs and even more pertainent, the shape of the tips which vary from manufacturer to manufacturer. It's easy to say that jacks should work with all plugs, but the other side of the coin should hold true as well...plugs should work with all jacks. In any event, he's not stopping there and he wants samples back for evaluation and he's already working wiith his factory. They've purged their inventory and are doing a bunch of AQL tests to determine the scope of this issue. here's the letter: Hi Peter, I am sorry to hear that you are having some reliability problems with the CL1384. From the units that you are getting back from customers for jack replacement, please can you send us the faulty jack sockets so that we can send them to our QA Manager for evaluation. Please send to Cliff USA ASAP and they will forward them onto our QA Manager in the UK. Is the problem due to the contacts not opening fully and if it is, do you think it could it be something to do with some of the plugs that are being used in the jacks? As you know there are many different variants of 3.5mm jack plugs out in the world and the dimensions can vary. Because we cannot control the type and size of plug that is used in our jacks, we have had problems in the past particularly with undersized plugs not opening the switched contacts fully. Regards,
