This adapter jack 3.5 to 6.35, which personally I use to connect my helmet on my amps, is simple and has a gold plated terminals. The sound is good, one is almost surprised by the sound quality for the price which is just over 2 in total (I paid the single object 104). I received the item within a reasonable time, nothing to say about that. However, the packaging of the object was a bit light, it was just in an envelope, even packed in a plastic bag, it could have been damaged. In short, a product itself excellent, unbeatable quality / price. But a shipment that could have been a little better treatment.
