1.) if you are referring to CX
's new longaul business class seats (the one they have on the 777-300ERs and most of the longhaul A330: they are in my eyes the BEST business class seats on the market. I was lucky to have been on them to Australia and back and a few trips intra-Asia (where CX
puts longhaul- and shortfaul planes, whatever is availlable) and they are great.
They have the perfect mix of privacy (you hardly notice the person sitting next to you), openness and roominess. The quality of the material is also really high and the colourscheme is elegant. The seat provides ample space when sitting AND
when sleeping (i sleep on the side and even then you have lots of space for your arms and knees etc). The table is of a great size also, and lots of storage ideas and little practical details have been incorporated into the seat. To top this all off, try to get a seat in one of the smaller cabins on the plane, it is quieter and feels even more private. Enjoy!
By the way, the new regional business class seat of CX
is also a huge improvement over the old one, lots of space and no person putting the seat in front of you in your face even in business class...
2.) No, the headsets are not "for keeping", they are also not that great, but they do a good job on the plane in covering noise, i prefer my own B*** ones though.
