The E282 must sounds great. I used to listen to them once, and to my ears, they sharesmany characteristics with the E484. They has good presentation of upper frequencies; however, I found it a little bit lack in bass response.
Sony MDR-E565 was given to me by my brother. E565 has a very big bass duct. They sound very smooth, but has very roll off high. The 565 probably has the heaviest bass on all sony earbuds. The 565 was a standard headphone on the one and only Sony Portable DAT Player. (can't remember the number)
Sony MDR-E555 is a little brother of the 565. The sound quality on this is a bit thin, and lack in punch. I remember that they has great high quality treble.
Sony MDR-E747 is a gold version of Sony MDR-E741. The sound quality is about on par or a tad better than Sony MDR-E848. My sister lost this E747...oh well ....
