Best phone for music.

Best stuff to play music (I feel) are:
1) Beats Audio HTC Devices
2) HTC One M8 Harman Kardon Edition
3) Marshall London
4) ZTE Axon
5) Ipods? (Not sure)
....
Advantages:
1) Beats - Heavy Bass music like EDM, Dubstep, etc
2) Harman Kardon - Clari-Fi i for increase in low-resolution tracks (MP3s and the like) with more detail, depth, and richness, LiveStage for quality and feel of a live performance.
3) Marshall London - Not reviewed
4) ZTE Axon - Better than Beats (Not sure)

So which from these are just a gimmick?
Which one is the best all-rounder?

What are the opinions from you guys?
