How can i improve the sound of Iphone 11?


I am using SE846 earphones into Ibasso DX90 and i love the sound. I recently bought TIDAL for streaming at home. 
I tried listened to TIDAL through my iphone 11 into SE846 and obviously, with no DAC in it, it was not as good as when using DX90. 

There are times i cannot carry the DX90 but will have my phone with me.

Is there a dongle i can put between the Iphone and SE846 that will improve the sound to match that of my DX90?

I have a PS Audio Dectet conditioner and I've been happy with it so far. It also helps with power surges. 
I know you have an Apple but what I did for my Android was install UAPP app. There is also an app within that app for a "Bit Perfect" app. Then you use an OTG USB cable. 

The UAPP makes the Android's DAC better. Perhaps there is a similar app for an Apple phone? 
I have a Helm Audio Bolt DAC that I have been pretty happy with. It's a USB C dongle DAC that I use with a Samsung S21. With an android phone I'm using USB Audio Player Pro to stream Tidal and Qobuz and I have no complaints. 
I intend to go this route for my iPhone 11 PM. iPhone--lightning to USB C--THX AAA Onyx. The Onyx decodes MQA.

I'll be using this https://www.amazon.com/gp/product/B09CFZZ8TJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 low cost, Lightning to female USB C adapter. 

My only worry is the known issue where the iPhone's Lightning port supplies little to no power to attached devices.
