To do what? Charging - certainly, listening to music - no. But you can connect the Walkman e.g. via "jack RCA" cable. Value Stereo jack - 2x Cinch (5m, Entry, 3.5mm jack, Cinch)

Unfortunately, I can't answer this question because I don't have the Samsung Galaxy Buds and - when it comes to classical music - prefer cables. Actually, the two products should be compatible, as both support Bluetooth. What can happen, of course, is that certain functions are not supported. But if you want to be sure, you'll probably have to test, as I couldn't find a useful review on the internet either.

Is this a joking question? Yes, of course, audio is played back through both earphones.

no

Depending on the manufacturer, this is not specified. It is also possible that one SD card works and another does not. So you can only try to go by the experience of other users.

Hello It does not have video playback. (If you could still make a phone call, it would be a mobile phone).

No, as you can see from the technical data, the maximum memory expansion is 128 Gb. This means that all sizes up to 128 Gb are possible.

Sony transfer programme (Music Center for PC) can access all music libraries on the PC, it is uncomplicated. Podcast should also work, as they are in a supported format. But I haven't tried that. https://www.sony.ch/de/electronics/support/digital-music-players-nw-nwz-a-series/nw-a45#downloads I am very satisfied with the device

The unit has a WM-PORT - this is a proprietary Sony connection.

The Walkman can be charged with any smartphone charger with a USB port. Simply plug the connection cable supplied with the Walkman into the charger.

doesn't look like it.

Had the same issue... I recently bought the NW-A45 for this purpose and it works perfectly, so I can strongly recommend it. Also because it allows you to put additional 128 GB, which apple never does…

With iTunes, no. However, if you have sorted all your music via iTunes, your entire music collection is in the iTunesMedia folder on your PC. You can simply drag this folder onto the player. (Since the Sony player works like a "USB stick"). Otherwise, you can use the Music Center programme from Sony. (It is similar to iTunes + it has a function where you can download album information and covers of all titles, which only works with purchased albums in iTunes). However, the programme is as slow as iTunes, at least for me. Since iTunes embeds the ratings in the file (mp3tags), they should also be visible on the Sony. Unfortunately, I cannot confirm this from my own experience, as I do not use the rating function :)

For Spotify songs, you need Spotify anyway, whether on- or off-line. That has nothing to do with this device. This device does not have a Spotify app.
