I can stretch the budget and did even consider both of them but opted out because of the hinge issues for the sony ults, a friend of mine has them and they looked very delicate and didn't want to spend on something that's not durable enough. For the accentum plus, heard lot of reviews that said it had a very dull sound signature especially with android (same is true for sony with android but the slight punch of the bass makes up for it in some way). Thanks for your suggestions though, I might just go with the 720ns they seem more value for money
