Can you use this: https://www.amazon.com/Lightning-Extension-Cellularize-Extender-Available/dp/B073Z1G71S?th=1

with this? https://www.apple.com/shop/product/ML8H2AM/A/iphone-lightning-dock-space-gray

The idea is that I'd be able to get a 3.5mm audio out for a headphone jack and be able to hold the phone in my hand.

I listen to music, podcast, meditations, ASMR, etc., a lot and have high-quality (and expensive) wired headphones I want to use. I have tried multiple lightening-port charger + 3.5mm audio adapters, and all of them have failed. The Belkin one is the only one old on Apple.com and it too has horrible reviews, many people saying it fails after a few weeks (just like I've seen with other ones). Thanks.

  • Why not get a lightning cable to the length you need and just plug into the dock? This seems overly complex.

    I see no reason why not

  • @Allan, I see your point, but I have an Otterbox case I keep my iPhone 7 in and I'd prefer to not have to take it out every time. Commented Sep 15, 2018 at 15:00

    Thanks, @Buscar웃, that is what I'm thinking as well. Assuming the lightening extension cable works as advertised, the connection should work exactly the same. I think I'll just buy them and try it, that's the only way to find out for sure! :) Commented Sep 15, 2018 at 15:01

    Amazon is usually good at returning crappy products. I would look at reviews and see how it is. Commented Sep 15, 2018 at 17:44

YES, it works perfectly! Just be sure to use a good, quality lightening extension cable like one from Anker - or the Cellularize cable linked above on Amazon. Finally, a reliable 3.5mm audio + charging solution for my iPhone 7 (inside its Otterbox case)! :)
