The APP 2 NOT sounding better than wired earbuds??! This is your opinion and this really is depending in what earbuds, obviously, expensive or NOT, you're comparing. A big generalisation like your comment is wrong, I'm sorry saying this.
Saying that bluetooth, by this nature, is more bad than wired earphones OR headphones is a complete fallacy, specially in last few years. And this is typical comment of many people that repeating what others (apparent audiophiles) are saying for many years. Bluetooth earphones and headphones are equal in sound, and often better (in tonal balance) than many wired earphones and headphones, for the human ear. This fallacy is very similar with opinions about better codecs (like LDAC), very high bitrates, lossy vs lossless. In blind tests you can finding proof, and this is not only opinion.
"APM is better because of the technicalities". What technicalities exactly?? Please look in my signature for the earphones and headphones I having in my possesion. And I owning several high-end high resolution DAPs before but my (good) ears saying me for long time that a lot of opinions are very exaggeration and "hyperbole" with this products and I selling them, and this is similar with other aspects I saying above.
Is OK if you or others people not liking the sound of the APP 2 at all or very much, probably they have other preferences (more OR less bass, more OR less mids, more OR less treble or combination of this frequencies). But generalisations about wired vs bluetooth (or lossy vs lossless), and very difficult proving/measurable AND really audible for human ears aspects like "resolution, imaging, staging, timbre", well,....I think I saying enough.
