For sony earbuds, there is only one model still in the market today in the $99 price range, the E888.
There are however discontinued models, which sell second-hand up to $300.
In the lower price ranges, there are the E7XX and E9XX series, they are very durable and have great sound quality, I used them for years in -20 snow, sun and sweat, back pocket etc., they held up fine.
For sony canalphones/IEM's, there are a plethora of options, for instance this month two new models were relased, the EX600 and EX1000, which look stunning, no reviews yet, apart from unboxing and some photo's of the manual's, as usual, the manual of the flagship (EX1000) goes into depth about research & development and the materials used in the process, this time around, sony have constructed the diaphragm out of liquid crystal polymer film, and are using strong driver magnets as usual. In my old sony earbuds, if you put them right next to eachother, they'd seperate themselves by a few cm's! That's how strong the driver magnets are.
Next month, the EX510 and EX310 will be released, which are a direct upgrade to the popular EX300 and EX500 series. The new models have a prettier design, better cables, metallic and vented housing and chic colours, no words on sound quality yet (since they haven't been released).
Next month there is a also the EX800ST coming, as a first from sony, it's a studio IEM, aimed only at studio use, however it will most likely seep into the common market just like the famous history of the MDR-V6 studio headphone.
Here is a picture of the MDR-800ST http://moesoyo.com/wp-content/uploads/2010/09/main_image.jpg
And here are many picture's of the the new behemoth of sound quality, the MDR-EX1000.
This is worth looking at, trust me! http://www.sony.jp/headphone/photogallery/MDR-EX1000/index.html
In other news, sony seem to be reviving their SACD format a little, I for one am happy that Sony are still going strong, because they pioneered so much of the audio world in the 80's and 90's, and I used their cheap little amazing earbuds along with a PCDP for so many years, the fact that PCDP's are dead, almost brings a tear to my eye.
