“I bought these because I previously had some Yamaha EPH20 In-Ear Headphone which I was happy with but did not suite my for the large variety of music I listen to. First I will compare between the Yamaha and Sony, both brands I trust greatly for budget ear buds. The yamaha I brought because I fancied something with some booming bass,fit was excellent and kept the noise out well I even used...” --Hawkinssa
“first of all, i believe, sony wanted to make hybrid earbuds for a better sound my expanding the soundstage, however the strategy failed. the soundstage has improved (the large size helps a lot too), but the isolation lacks and the sounds are distant (they seem tiny as if they're far away). the ex300 and ex500 from sony offered better soundstage and isolation. as for sound, yes,...” --thesurvivor90
“Build Quality: Not much to say than a solid IEM. The outside is "gunmetal" it looks like metal and feels like metal, but then again. I have been fooled before. The clip ...is just a clip, no deficiencies or poor moving around from it. The L shaped 3.5mm jack is also good. No weird wiggling parts, feels and looks solid. As it's an earphone, this section is generally good. The tip of the earphone...” --bowei006
“ As of 2013, I could only find one pair of these on the internet. It's a shame because from my experience, cheap earbuds are oriented around the muffled bass emphasis and exhausting higher mid ranges. I myself came from the Audio Technica a900x and Bose IE2's which sound darker compared to these $10 earbuds. I love rich vocals and acoustic...” --Nec3
“ XB90EX Review By - Snyper0012 Accessories: lots and lots of tips. I got 7 pairs of tips, 3 which include foam insulation for better isolation. They are sony hybrid tips which are pretty popular since they are comfortable and isolate well. Build quality:...” --Snyper0012
“I have 5 sets of the e30 with varying amount of time on them ranging from brand new to 500 hours and there is so much variation that I don't know which one to review here. But generally, I'd say the e30 is neutral/warm yet detailed with a pleasing full bodied sound. It's 'hi-fidelity' in the sense that it imparts virtually no sound signature/sound stamp of its own onto your music...” --thelostMIDrange
“First of all, I'd like to thank 'H20Fidelity' who recommended this IEM to me. I was not sure whether to go for this brand as i did not hear of it before. but thought of givin' them a try. Got it under 40USD. I had Sennheiser Precision 300-II before these and I liked them. The intention to purchase an IEM that was like Senn Precision 300-II was to have a pair of headphones that are just fun to...” --akshayshah12
