Dmac6419I also have the LCD-i4 actually, and from what I read in antdroid's review, his comments are pretty accurate with regards to the detail retrieval of the Timeless by comparison. For me, I would say the bass is definitely more fun and enjoyable on the Timeless than on the i4.
antdroidYes, especially with ifi zen's x-bass or true-bass, simply amazing!
I haven't been wearing anything else. Selling off much of my more expensive gear tbh. If people are powering these on phones it might not be great. They need some amp power but not a crazy amount, to get the best from them.
