Which one do you think is best for the above conditions?

Any of them is fine, if your headphones connect using AAC you may hear a very slight difference between an MP3 and AAC file, a FLAC file assuming CD-Quality or higher will get down converted to AAC when the audio is sent to the headphones

r08zy is correct.

You may not like to hear this, but the Bluetooth connection is bad enough, it's pointless to use anything better than mp3 quality.

For those of you who replied so far, I did notice a slight difference when listening to FLAC compared to both MP3 and AAC. I almost certainly don't think it was a placebo effect because I tested it multiple times. The music felt slightly more open, but only very slightly. Therefore, I think I'll keep storing and using FLAC files, so that they will be readily available when I get better headphones.

One thing is obvious, all audio formats are decoded to PCM, send to the Bluetooth sender and encoded to AAC.
MP3/AAC comes in many flavors.
If it is a low bit rate MP3/AAC you beter use FLAC.
If it is high bit rate you probably won't notice the difference.

When you say high bitrate, do you mean 320kpbs?

320 MP3 or 256 AAC sounds pretty transparant
