    iPhone 6s Sound Quality

    I'm sure you know this, but given Gizmodo's usual way of operating, if you do pass something on to them, try to give them a clear perspective of the scope of the problem and the mix of findings contained even in this thread. Besides my videos and this thread, these other URLs might be useful as...

    iPhone 6s Sound Quality

      As far as I know this forum is basically the only place where people are actively talking and swapping notes about this issue. You would expect this kind of discussion about an issue that only really affects users with some fancier IEMs (so far we have not been able to nominate a single pair...

      That's interesting. When I tested this, I could completely mute the output and still get various noises.

    iPhone 6s Sound Quality

      As far as my experience goes, anything that makes the phone think about anything will cause some kind of burst of noise on the headphone jack. It seems that in particular the app switcher and the system settings tray in particular makes very distinct noises, but any background activity causes...

    iPhone 6s Sound Quality

      As far as I know all Apple has just acknowledged is that they've received multiple similar reports, they haven't acknowledge it's a 'problem' per se.   This video should demonstrate many of the situations where you should be hearing the noise, and what it should sort of sound like (it will...

    Because of the nature of the problem, it's really difficult to know what is going on here. Either   The issue is batch or model related, which explains why some users hear the noise and some don't. So far we've ruled out Samsung vs TSMC chips as being the differentiator. We don't know if it...

      I had a Samsung 6S, vwinter has a TSMC 6S+. Both hear the buzzing.

    iPhone 6s Sound Quality

    So just to add a little more information in light of other reported differences between the TSMC and Samsung chipped iPhone 6S, my unit is reported as a N71AP in the 'Lirum Device Info Lite' app suggested in the Engadget article. This means it's the Samsung chip. Don't know if this might be a...

    iPhone 6s Sound Quality

    Got a quick update from Apple support yesterday after my issue was escalated to engineering; they said they were investigating and confirmed that they had received several similar complaints. So that's promising.

    @Whitigir No worries about your comments, I understand where you are coming from. I've learnt from the past that in these cases it's best to verify these sorts of things before posting about them, which is why this time I was very careful to confirm on the demo units that I could hear the noise...

    At the moment I'm waiting to receive a replacement Takstar Pro 80 that was purchased for me by LHLabs.   The replacement Geek Pulse I received is working well enough and I quite like it. On firmware version 1.4 it occasionally drops out after a few hours of use and requires a reset. Apart from...

    To be clear, Diana did offer to give me a shipping label for the faulty headphone, but I said:     I didn't want to send out another package if the initial result of the assessment was going to be negative.   I'll give you the dimensions of the headphone so you can provide a shipping...

      Hey Casey, I think there has been some misunderstanding, which is why I have not sent the headphones in yet.   As Jody Edit: Gavin wrote previously,     and also:     I read that to mean that I should send the faulty headphone in AFTER the third party claims adjuster had looked...

    Well I'm a little astounded. I've had my faulty Geek Pulse with LHLabs waiting for them to assess the unit so they could determine if they would compensate me for my damaged headphone. Everything has gone smoothly, but I noticed that Diana was sending form replies that suggested it was being...

    Okay, I know this is very off topic, but it's very interesting. My Zoom H2n does 96/24 recording, so I was able to do my own tests.   So first of all, I ran the high frequency test tone file at http://www.audiocheck.net/audiotests_frequencycheckhigh.php through Musicscope and got this result...

      That's really interesting. Thanks for sharing that. I never realised that iTunes did that. I'm assuming they filter the ultrasonics to avoid equipment damage, but it's a bit annoying not to know that. Do you have any idea what iTunes does with 96kHz files? I might try messing around myself...

      I'm surprised that the application isn't agnostic to the multi output setup. It's an OSX system level thing where it combines the two outputs and treats them as one single output device that shows up in any application as a output hardware option.   Where did you get the idea that iTunes...

      I really want to be clear on this: in the 1 month my ticket was open, I did not simply just sit there for a month biding my time. There was back and forth on the support ticket. I was given no indication in any way that I was being treated anything differently from a regular customer or that...

      Gavin, I appreciate the time you are taking to write this statement.   But if you have watched the video and read the ticket, I have described the problem: after the unit has been on for some time, the LED starts to flicker. The unit will then send a popping noise through the headphone when...

    So I had a 20 minute conversation with Casey, and later on joined by Gavin, on Skype. Here's my summary the key points of the conversation.   Casey states that as soon as my Youtube video was uploaded, he reached out to me across various channels - which is true. Gavin stated that as soon as...

      Well of course I would be surprised if they decided to share the survey, but it never hurts to ask ;)   Technically according to the Indiegogo terms of service "Campaign Owners will respond promptly and truthfully to all questions posed to them by Indiegogo or any Contributor."

      Sorry, misspoke. I mean sharing this survey: http://goo.gl/forms/AR827KTu3t   That's where that response about the Beats Solo is coming from.
