Was something of an impulse purchase. Wanted to treat myself to something vaguely luxurious but useful.
First the negative points:
> Putting them in my ears is a major faff. The cable is clumsy and gets in the way, and the buds need pushing in hard and held in position for a wee while; otherwise they fall out easily. With practice, I hope this gets easier. I expect I'll be using these 'phones in a confined space (on a plane or on a train when on business trips) so I don't really want to battle with them when putting them on.
> Wearing them can hurt the ear canal. Fortunately, included in the package I received were many different types of bud, and after a fair bit of experimentation I found a painless pair for my ears (consisting of soft yellow foam).
> They are expensive.
Now the positive points:
> Many different earbuds to choose from.
> Cable is a useful length.
> Cable is detachable (so can be replaced if damaged).
> Comes with an optional volume control and an optional adapter for 6mm audio jack connections (I was not expecting either of these things).
> The world becomes eerily quiet when wearing them, and others around me cannot hear any noise pollution from them. Their sound isolation quality is excellent.
> Above all, they sound sublime. When I am listening to music, I forget I am wearing the phones because the music takes over and demands my attention. This is what listening to music should be like. I have a half-decent hifi set up properly at home (high-def uncompressed digital audio source; Music Fidelity DAC and power supply; Quad power amp; top-end cabling; and Monitor Audio floor standing speakers) and I am hearing details with these headphones that I have not heard before. Am very impressed by this.
