Yet, whenever I use the wired cable to connect the Bose headphones to the MacBook Pro, the issue only seems to disappear when on battery power OR using the grounded extension with the power adapter. However, I can confirm that when using a wired cable from the Bose QC15 headphones to the MacBook Pro's headphone jack while using battery power, the buzzing noise also does NOT occur.

That is, using bluetooth resolves the issue entirely. When using the bluetooth mod, the buzzing does NOT occur, regardless of whether the MacBook Pro is charging without the grounded extension, with the grounded extension, or on battery power.
The Bose QC15 headphones are not wireless, but using a compatible bluetooth modification, I am able to make them wireless. Thanks for your comprehensive look and hope this is something your team can do. Here are my questions: (1) is it possible for you to recreate this issue with 2017 MacBook Pro and charger? (2) Is this issue resolved when using the newer power adapter with the 2017 MacBook Pro? and (3) Does this issue occur on the new 2018 MacBook Pro with the old power adapter or the new power adapter? However, the issue still recurs with the replacement 2017 MacBook Pro I received. When this didn't resolve the issue, they advised that the machine was defective and to get a replacement, which I did. However, when using a grounded extension cable to connect the power adapter, the buzzing noise disappears without the need to touch a metal part of the laptop.Īfter taking my laptop to Apple about a month ago, we tried using multiple power adapters, and multiple battery-powered headphones. 60W AC Power Supply Adapter Charger For APPLE MacBook Pro 13 Inch 13' 13.3 MA 67' Cat Tree Tower Condo Furniture Kitten House 68' x 24' x 0.24' (6.

Had a scenario regarding the power adapter and was hoping you could shed some light. I recently purchased the 2017 MB Pro 13" and saw your new teardown of the 2018 version.
