That definitely makes a difference and I think a lot of attention was spent by Sennheiser to use that as the primary 'tuning' aspect of the HD5/6 driver design. I also found that placing different and varied shapes of foam within the void that's created by the HD5* series headphone shells has a...

Thanks for the suggestions, but being an MOT cable-maker myself I'm pretty well-attuned to how different combinations of wire and connectors can affect capacitance, inductance, impedance etc. I agree with your suggestion that connectors using different metals in terms of capacitance (not...

You don't see the S/S2 in the photo becasue they were SENT BACK. The ones in the photo are the ones worth keeping in my opinion.

Just my two-penneth. I really wanted to hear evolution in the 660S and the 660S2 but all I got was 'dressing' akin to what car manufacturers do to any given model during the course of a production run; adding bits and pieces to give it a 'mid-term refresh' to make it look up to date in order to...

I couldn't possibly. It would disrupt my little OCD-filled world and send me into a tailspin of confusion and despair! lol One will turn up. Just keep an eye on the usual selling platforms like I do :wink: Actually, there's maybe half a plan to do something in combination with a cable I am...

40 European Euros brought home HD565 set number 12 today and these are probably the best-condition set I've ever reeled in. Not a mark or a scratch or a blemish on them anywhere and relatively free of the usual dust and skin/hair/mucal detritus. As a matter of course however they are always...

Let's also not forget the failure modes that LMB's can have; premature capacity failure or reduced lifetime operation explosion risk due to manufacturing/handling faults requirement to declare LMB devices and restrictions to travelling (should have been an obvious one due to the primary user...

Let's hope the CP13 specs can also compare favourably with the DDII specs from 40 years ago: W&F - 0.13% (DIN), 0.08% (WRMS) Frequency range - 40-15000 @4Hz Output - 2x 20mW Battery life - 9h Weight - 290gr

That logic is fundamentally flawed in several ways and it's absolutely NOT the same with any western company! Commercial success is derived from a product development path that that includes and derives value from consumer/market research as well as the full complement of technical aspects...

As per the title, can anyone advise the correct pinout for the 3.5mm TRRS connector for the Hifiman Deva? TIA!

Firstly, thanks for addressing the points I raised. If you are asking for opinions and ideas here on the forum then you should at least expect a lot of interest from 'portable analogue audio / Walkman enthusiasts' such as myself and many others here (?) If that's a genuine goal which targets...

It's against forum rules. You'll find one if you look in the obvious places.

A good-condition Dolby S 3-head deck e.g. Sony TCK815S will cost between €200-300 or cheaper depending on how hard you look. If you think that's an exhorbitant price then your expectations are unrealsitic. However, the main point is that FiiO are definitely NOT going to include what you keep...

Assuming FiiO is 'ready-for-market-deployment' after developing this product, then here's what we defintively know : W&F = 0.15% RMS ...which in my opinion makes it unsuitable for anyone wanting to listen to classical music or where long note decay exists. This limits it to certain music...
