@bruxinho, the cable itself is very nice at the moment. This is at least from what I see and Bob said. Adding an extension cable might make the sound worse as adding joints or jacks to any cables can cause some noticeable loss in overall sound.
I had ATH CKM50 in the past and it has a short cable and extension cable as you mentioned. It was good with its short cable but when I plugged the extention cable I was hearing some loss in overall sound. Even though it might look as a good idea to add a plug for extension cable, the results might be worser than what you think. So I don't prefer any extentsions or jacks on any Trinity models since I don't like the idea of loosing the overall sound quality. Of course, except the short right angled jack adapter.
it's a fair point, but it does depend on your usage. for general listening, the longer cable wins. for gym use, the short cable + extension will be fine for the majority of cases; if you're working out you don't need *perfect* quality as if you're working out right it's only background. the difference in one joint will be minimal - you're already happy with the adapter, so it's no different to that. certainly, the meelec s6p i'm using now has no appreciable difference between having the extension cable in use. it's like a car radio - how hi-fi can it really be with background noise and vibration? in the gym, the background noise is added to your internal noise and the effort you're putting it and the heartbeat pounding in your ears... there's a limit to how much difference an extension cable will make in that scenario.
like i said, though, i'm in the process of discussing the gym usage separately to the kickstarter offering; the only thing i would like to see added for the release on kickstarter is memory wire as personally i find that more comfortable and secure, and it would allow gym use with them if i wanted to chance it (even though they're not sweat-proofed). the techne's over-ear fit look ideal for that, but the lightness and sealed nature of the hyperion suggest that would probably work too.
utterly perfect for me would be delta + memory wire, techne/hyperion + memory wire and a short cable + extension and a control button so i could use them in the gym. ideally, the techne would come with a fixed filter, too, for that use to make them more secure/sealed. but that's for me, and for my use case only. even with the long cable, i'd likely chance techne/hyperion as gym headphones if they had memory wire as a) i reckon they'll sound better than my meelec s6p if my alfa genus are anything to go by and b) the secure fit is a higher priority than the cable length and controller for that usage. just as headphones? well, i pledged for the delta for that.
but that's perfect *for me* and for my *use cases*. i doubt every other person would agree. in fact, one of the more interesting discussions (to me!) i had was with another user who preferred a long, fixed cable for his exercise use as it involved stretching, which meant a short cable + extension was more likely to come loose. he also taped his at the back of his neck, which doesn't work for me as i have long hair, but meant he didn't see the need for memory wire. two very similar usages, but two different preferences.
ultimately, you can't make everyone happy. the option is to make multiple variations, or to make something customisable. but it's bob's choice as to where he wants to take it, as it's his company and his design. if he wants more input from me, or testing of prototypes, he's got it for the asking. otherwise, all i can do is see what other people want and let bob see whether there's any sort of consensus, or whether there's room for innovation.
