Really if you have decent software with an equalizer there IS NO DIFFERENCE. atleast on the phone the app that runs the mp3's gets updated constantly. MP3 players software is likely not updated often nor adding new features. Rocketplayer will continue to add features and continue to fix any problems that come up. If you buy an mp3 player and you already have a phone then your just wasting your money. its still going to be the exact same song going through the same types of filters into the same 2.5mm jack into the same headphones that produce the SAME sound. The range of sound is not improved by using an mp3 player over a phone. an mp3 player is just a peice of software with a headphone jack, you are getting ripped off if you think otherwise. The filters are the only difference and they are SOFTWARE related, which is all effected by the EQ which if you have a full range EQ it doesnt matter what its on. So long as you dont have some retarded phone with interference problems (which ive never even heard of this problem) then it will be the EXACT same thing just more plug ins and features attached to it.
The same goes for flac players or anything else for that matter, if it can output the full range of sound its the same no matter what its coming out of. the sound difference will only differ by software filters. Mp3 player or flac player software filters will be no different then a phones or an app's filters. Most likely the filters being used are from the same programmers anyways
Hold up there. There's actually a lot that dedicated hardware can do. Both phones and portable players will have a DAC (digital to analog converter) but the quality of them can be drastically different. True, for mp3s you don't here much of a difference but that's due to the lossy nature of the format itself. That being said, some subtleties can be heard by some if you're using a decent set of headphones.
Now flac files... Man... When it comes to audio hardware is actually everything. A DAP (digital audio player) is a hell of a lot more than software and a headphone jack, which by the way is actually 3.5mm. The hardware on the player has to take the digital audio signal, so your (lossless) flac file, and convert that into an analog audio signal. Phones don't always have the best implementation because, frankly, there's a whole lot else going into the manufacturing.
There's a whole lot more to explain here, so do some research man. Bottom line you're completely wrong. Having a dedicated player like the FiiO X3 will make a huge difference as long as your playing lossless 24bit audio files and using a good set of iem's or headphones.
As for mp3s you are right. Any old thing should do, it will sound mediocre regardless.
