Sorry, forgive me for jumping in, I was posting above and saw the above - and as i have just been listening to PM4 and now happened to have the Cello's in...
Had my cellos for a week now - getting near the 100 hour burn in and I have to say I am super impressed with them. Really can't fault them
They have a superb 3D soundstage, not too far out of the head but depth is great with an especially good clean and clear seperation of instruments.
The bass is warmwith a good sub bass that is perfectly restrained and complimentory - its there and adds a really nice enjoyable element but it never interferes.
The treble I find is beautifully sparkly clean, clear yet smooth
They can be quite warm and big & fun but with that seperation and clarity it all combines to make a really impressive iem
Im happy using KZ foam tips with them at the moment
These are a great earphone - Cant reccomend them highly enough. Sometimes it lacks the refinement of TOTL but not in a way that I would want to take them
out for that reason.
I'll do a descent review later
