“When i bough these i had no id'ea how they would sound. I read some reviews but it is a iem that was flying under the radar and kind of hide in the shadow of the BA200 which is TDK's flagship ( was, i think it´s discontinued ) All plastic build, feels solid but not expensive. They do have a great fit and can be used both with deep or shallow insertion and a various amount of...” --Arvan
“ "The TDK BA100: Like Beige Wallpaper, But..." ...I Like Them! I have all of about 4 hours of listening time with these headphones, but I don't think I need more to justify my thoughts. They are BA (balance armature) drivers so burn-in is not a factor. For this test I used my iPod Classic (no external amp and no EQ adjustments). Many, many different...” --SoulSyde

“TDK IE800 VS. BA200 IE800 $40-90 (Discontinued by manufacturer) BA200 $55-120 (Discontinued by manufacturer) (on Head-fi, Ebay, and Amazon) Some have even found these at Ross and TJ Maxx for $10-20. Packaging: Pretty much the same packaging for both IEM’s. If both packages were side-by-side, you’d probably have to read the labels pretty carefully to...” --aiaosu
“These IEMs received quite a hype in the forum, with lots of Canadian head-fiers saying wonders about them for the price. As I found these on ebay for 12 euros (10 dollars more or lesss), I gave them a try. The first reaction was the fit. It is just perfect for my ears. I believe it is due to the angled nozzle. They hold in incredibly well and are among the most comfortable IEMs I've...” --Mellowship
“ Firstly, I'd like to thank Rock Jaw for the Alfa Genus sample. Only a few weeks ago I hadn't heard of the company Rock Jaw, however through a friend was offered to sample one of their new products. Being more than interested in the filter adjustment tuning feature and neodymium drivers I happily took on a review sample. Let me say it's been more than interesting and delightful,...” --H20Fidelity
“**Edit: Added pictures of the filter nozzles. When Rockbob posted the “Name our latest soon to be released product from ROCK JAW” thread for the Kontrol replacement, I took the first chance I get to enter. Several agonising days of waiting until the closing date, and finally the announcement, I was greeted by a PM from Rockbob himself advising me that I had won the contest....” --penmarker
