“The ES800 are the kind of IEMs you won't like how they sound out of the box: they sound thin and aggressive, with piercing mids and highs. Then you will question the design: the hideous "gold drop" on the back, the flat cable, the enormous cable splitter. The tips are not so good either. So, there is a chance that, for 3 or 4 dollars, you will give it to that annoying cousin, or forget about it...” --Mellowship
“For 6.5$ you can't do much better, very fun sounding earphones and relatively comfortable. These sound almost like 30$ AKG on ears headphones. Sound very good in Psy Trance, Rap and some acoustical rock but sound only decent with brighter music. Comes with a one click remote that can pause the music in one click and moves to the next track in 2 quick clicks (but that doesn't...” --Viber
“The Awei Q9s are really bang for bucks! You can't go wrong with these! Unless you have tiny ears... Packaging: the packaging is standard. It brings the S/M/L tips and a shirt-clip. However, the earbuds are snugged in a very good foamy protective material. Build quality: the Q9s look nice and they sure are big. So big that I doubt anyone with small ears will be able to insert...” --Mellowship
“ What can I say about these? I saw a lot of people going for the Awei branded items on eBay, so I got one myself. They were surprisingly good and surprisingly bad at the same time. I will explain. Pros Housing build - For $2, an aluminum housing is quite exceptional. Accessories - While the Awei K80 only comes with one pair of tips, they are surprisingly pretty high quality. Somewhat...” --pro1137
“Copied from: http://www.head-fi.org/t/686039/cosmic-ears-ba4f-review I'm finding it hard to rate these, for the price I would give them 5 stars on every department. But I'd rather rate them, referenced with the idea of what the very best cIEM could be. The BA4f with the Ice Blue color Short History Before I started my journey into the cIEM...” --Marleybob217
“First of all I'd like to say the customs and the cable are both insane, the customs look incredible and the linum cable and connector beat the hell out of any other CIEM I've seen around. Cosmic Ears list this as a jack of all trades monitor which I do agree with. I'm coming from a 4BA model to this 2BA and I've been pleasantly surprised by the sound. I haven't had these a week yet so...” --daftpolecat

“This is in my humble oppinion the very best bang for your buck custom in ear monitor on the whole market. For 250 british pounds you get a very nice piece of equipment, from very nice people too! The guys at cosmic ears care about their stuff being done properly and on time, they checked everything to be correct, from my ear canal impressions to colour, logos, letters, etc. They also come with...” --ardacer
