Stealing Jacek’s post above as a template...
I can confirm audio stuttering on my brand new Bose NC 700.
Details you've asked for:
- Received out of box with Bose NC 700 firmware version: 1.1.4-1144+be3bf4b, tested for a day and seemed OK but did not do significant testing at this point prior to update.
- Updated to firmware version: 1.7.0-10068+f3675e6
- Bose app version: 4.1.1.
- Issue: sound has occasional static and stuttering with Spotify on iPad Pro 4 12.9 (2020 model) on IOS 14.1 during playback.
- Condition 1: paired with only iPad Pro, no other devices - stutters around once per hour to once per two hours. The stutter is like a digital glitch in the audio for less than 1 second. Like a scratch on a CD or a brief drop of internet connection (It’s not this by the way as all tests are with Spotify offline).
- Condition 2: paired with iPad Pro and iPhone 11 Pro (both ios 14.1) - stutters and static more often, at least twice per hour.
- I experienced issues from the beginning. I bought the NC700 headphones 4 weeks ago. Installed the Bose app and got a firmware update to the version listed above (which I blocked for a day to try version 1.1.4 first). The initial firmware version was 1.1.4
- What I did:
- switch on and off headphones;
- un-pair and pair headphones many times;
- reset headphones multiple times;
- restart all devices;
- update everything to the latest versions - firmware, apps, drivers;
- use different Bluetooth adapters and applications;
- searched the web to find solutions...
- Downgraded from 1.7.0 back to 1.1.4. This firmware with one device connected – iPad Pro above would stutter perhaps once or twice in 8 hours and the stutter is significantly less, almost imperceptible, (whereas with 1.7.0 it is very noticeable and distracting.) Also there is no static or crackling. I would say with 1.1.4 and one device paired they are 99.5% fit for purpose.
- Other Observations and Comments
- I have not gotten around to pairing a second device again with 1.1.4.
- With 1.7.0, I seem to hear a brief crackle each time they are first turned on within the first 30 sec of use. This does not happen with 1.1.4
- Battery life has been similar with either firmware and they both charge to full, around 19.5 hours in either case.
- 1.1.4 reports the wrong battery time on power-up voice. It seems to report the last battery life before charging. Pressing the touch pad again then will report the correct battery remaining.
- Disconnecting other devices in the App reduces the issue but is not as effective as removing the other devices altogether.
- I also tried up to 3 devices and the more that are connected the worse it gets.
- I am now running 1.1.4 with only one device registered and connected via the app.
- I keep the app off and disabled to background tasks to ensure it does not update to 1.7.0
- Sometimes when you add the device via the app you get a LE Bluetooth profile and normal profile listed in IOS. Other times the LE device does not appear. Currently I have both listed on the iPad Pro and this seems to be working almost faultlessly.
- ANC seems the same with both firmware, I can't pick a difference.
- A bit more base with 1.7.0 but I wouldn't say it sounded better.
- I don't miss the equaliser at all, would much rather core functionality worked 100%
- Call quality is amazing with either firmware and was the reason for buying these over the Sony XM4. (Just need to get the Bluetooth connection 100% reliable, which should not be that hard given all my devices are BT5).
- Hopes and Dreams
- I would prefer the disconnections to be remembered. It is annoying that if you have three devices they all connect as soon as you turn the headphones on. I would prefer the app remember which are on and which are off.
- I would also prefer a way of switching profiles from the headphones with a button between single devices, e.g. press voice assist and the headphones cycle through the available connections one at a time. Auto switching could be the other option of course.
- A toggle in the app to disable firmware updates. I would like to decide if I want to update or not. This ideally should include whether to check, download and or apply.
If you need any more details, I am glad to help you.
