Dear monkey, it is a lot of effort to compare two earphones to another. You have to do A-B comparisons over and over if you don't know the record by heart - and even then you cannot be 100% sure how it's supposed to sound. If you want to seriously compare two earphones, it takes a lot of time and also a lot of concentration (that is pure energy) to do this.
Then people ask to compare Toyota to Porsche. I don't even know where to start?! The interior, motor power, ... steering response???
Please be so kind and answer the question yourself if you're not too lazy. If you don't know both earphones closely, please STFU. Thanks.
