Are older iPhones such as my 6S simply incompatible with the newer wireless headphones such as my
Sennheiser HD4.50? These phones seem to work with an iPhone 10R ?
iPhone 6s, iOS 11
Good afternoon AGBELL2020,
Welcome to the Apple Support Communities!
I understand you are trying to connect your Sennheiser HD4.50 headphones with your iPhone 6s. Is your iPhone updated to the most recent version of iOS? I'll include some resources hear for connecting Bluetooth devices to your iPhone. You may need to reach out to Sennheiser regarding these particular headphones. If these headphones also offer a wired connection, you can get an adapter for your iPhone.
Update your iPhone, iPad, or iPod touch
