How can I play HiFi music on my headphones?

I ordered the Sennheiser IE 500 Pro to listen to music in high sound quality on the go. Now I'm facing a few problems with music playback.

At home I use Deezer HiFi (FLAC, 16bit), which I also want to use on the go. However, my smartphone (Google Pixel 3, 64gb) does not have nearly enough storage capacity to listen to my music collection offline and streaming in HiFi will surely quickly consume my monthly data volume. Apart from that, this smartphone has no usable audio output.

With this in mind, I'm now looking for a device for hi-fi music playback on the go. Despite researching for several hours, I didn't get much smarter and could only get a rough overview of the opportunities that were opening up to me. In short, I'm looking for a device on which I can store my music collection and from which I can play it and thereby fully exploit the potential of my headphones within the quality of Deezer HiFi.

I'm now thinking about getting a second smartphone to play music. The smartphone should have a 3.5mm audio output that fits my headphones and an SD slot to expand the system memory. I don't want to spend more than 200 euro on this. The three models I have come across so far are the HTC One M10, the Marshall London and the LG G5 with the LG HiFi Plus expansion module from B&O. The ratings that I find on the Internet are all very different, so they are ambiguous. Apart from this, the ratings may not be reliable indicators due to the different publication dates of the three models. If one of the three models is actually recommended, or if there are other recommended devices (possibly at slightly higher prices), I would now be interested.

Alternatively, a HiFi-capable playback device with a large internal or expandable memory could be considered, for example a Sony Walkman with Android or an iPod (i.e. A device on which I can use Deezer), only I have no idea whatsoever whether one such device is good at all.

The probably last alternative would be a mobile Hi-Res DAC, such as the RHA Dacamp L1. Since the impedance of my headphones is low at 16 ohms, a long-lasting battery is probably not necessary if you need it at all. In addition, I could also use the headphones with improved audio quality on my laptop. The problem of storage would still exist. Are there any hardware solutions for system-internal memory expansion for my smartphone that can be combined with an external DAC?

I would be very grateful for any advice that would allow me to come closer to solving my problem.

How about that:

In addition a Micro SD with 512GB and done.

The problem is that I can't use Deezer on such devices, so I need a device with Android or iOS.

Sorry, have the max. Read over 200 euro.

Then the?

The LG V50 is said to have this Quad DAC, which should be neat. But I haven't read the model so I can't report anything.

Every cell phone can be combined with an external DAC / KHV via USB.

I would say to the DAC that you overestimate that. 16 bit (44.1kHz) corresponds to 99.3dB (I think) SINAD, which is not uncommon for cheaper DACs, such as the 10 euro Apple USB dongle (which is unfortunately only partially compatible with Android smartphones).
Due to the low impedance of the IEMs, you want an amplifier that has a low output impedance so that the frequency response is not distorted.
With the high sound pressure level, you don't need a lot of output power, but you want an amplifier with quite good SNR at low loads.

One option would be the Meizu HiFi Pro Dongle, I really can't think of anything else great.
But of course you could theoretically also buy a HighRes player, you probably need one with Wi-Fi and just app compatibility or whatever.
Otherwise, the LG G5 would be an option, as would a newer G7, for example.

But first listen to the KH on your smartphone. I doubt that you make a clear difference
