AirPods Delay Attributed To Apple Ensuring Both Earpieces Receive Audio At Same Time (macrumors.com) 189

Posted by BeauHD from the any-day-now dept.
An anonymous reader quotes a report from Mac Rumors: AirPods were originally slated to launch in October, but the wireless earphones were later delayed. Apple said it needed "a little more time" before they are ready for customers, and it has yet to provide an official update since. While the exact reason for the delay remains unclear, a person familiar with the development of AirPods told The Wall Street Journal that Apple's troubles appear to be related to its "efforts to chart a new path for wireless headphones," in addition to resolving what happens when users lose one of the earpieces or the battery dies. The Wall Street Journal reports: "A person familiar with the development of the AirPod said the trouble appears to stem from Apple's effort to chart a new path for wireless headphones. In most other wireless headphones, only one earpiece receives a signal from the phone via wireless Bluetooth technology; it then transmits the signal to the other earpiece. Apple has said AirPod earpieces each receive independent signals from an iPhone, Mac or other Apple device. But Apple must ensure that both earpieces receive audio at the same time to avoid distortion, the person familiar with their development said. That person said Apple also must resolve what happens when a user loses one of the earpieces or the battery dies."

Manufacturers utterly don't give a shit about consumer input or feedback anymore when it comes to design. Oh look, another vendor is ditching the headphone jack so they create more profit streams.

      Sending data to both ear pieces means that both ear pieces are master, this gives you the ability to use one while the other stays charged and switch them when the first one dies, not possible if one of them was a slave. This is how I would use them, provided they are comfortable and don't fall out of the ear as easily as the current earbuds do.
      • Thanks (to TheFakeTimCook as well). If that's the case couldn't Apple have them they operate in master-slave mode when both are available and switch the slave to master when it's the only one available?
        • Yes, they could. The CSR 8670 can do that very thing - and it maintains nice and tight sync as well. Plus AptX support...
      • Oh shit... I hadn't even considered that each earpiece would have a separate battery. Worrying about ONE battery was already too much for headphones.

      1) Get in touch with Apple customer care where you can buy a new earPod for $100. After receiving it, you can take it to an Apple Store, or call customer support again, and in 4-5 business days your new earPod will be synced with the other and you can get back to enjoying all that wonderful iTunes music.

    Problem 1 - Lose one earpiece.
    Solution 1 - Maybe use a tether of some sort to keep the earpieces together?

    Problem 2 - Battery dies
    Solution 2 - Maybe have that tether double as a charging lead? You could plug it into some sort of handy port on the phone to keep the batteries charged up.

    Problem 3 - Audio sync between earpieces.
    Solution 3 - Perhaps shift the audio hardware to the phone, decode the audio there and then transfer simple audio signals down the tether to the earpieces? That might work.

  • They're spending hundreds of thousands of dollars researching this, when they should have just stuck a $5 audio cable on them..

  • When we hear a sound and can tell what direction it comes from, the volume in one ear compared to the other usually helps only a little. Direction is determined more from which each the sound reaches first. There can be up to 0.7 ms of difference in time. So any sync issue that's anywhere near 0.7 ms will make it so the sound sounds like it's constantly coming from one direction, even if the volunteers are the same.

      Actually, a lot larger effect is gained by the differing attentuation and reflection of the signal by each ear. This is how "2-speaker 3D sound" systems like QSound, A3D etc. worked - by slightly changing the actual sound pattern to simulate passing through your skull / around your head instead of just changing the volume.

      The problem is that 0.7ms of delay is NOTHING when the primary data channel is operating over something like Bluetooth (i.e. a 2.4GHz carrier, data rates around 1Mbit/s, etc.). In those

      • And if you're really that worried, you buffer ever so slightly (even a few ms will do) and spend more time on sync to make sure you keep the same idea of "now" on both earbuds.

        They probably buffer a lot. Existing bluetooth headsets will keep going for a few seconds after you remove the phone. The issue is likely timing the buffers to microsecond precision.
