What earbuds/headphones you were using before ?
hiya Berlin, I am happy with the headphones...tremendously better than the various earbuds or stock phones I've burned through...most recent portable earbuds I have are Sony, the plastic mold type that sit in the ear, with rubber hook over & behind the ear, at least they have not broken.
the Superlux HD681 & HD688b headphones are as expected, good sound for the cheap price...outward build quality is as expected too, in other message I compared the plastic to interior of a Toyota vs. Lexus for example...maybe not a good analogy since I remember Nissan havin really cheap feeling plastic dashes...anyway, the cables & 3.5mm plugs however are durable, unlike those of typical earbuds & stock headphones where they can kink easy.
the Superlux HD688b has a break-away cable, and comes with a 1M cable & 3M cable...I guessya can use ANY 3.5mm extension cord as the cable...with flat EQ, the HD688b has less bass than the HD681...both headphones can get your ears hot due to the plastic pads...but that has happened with any headphones I use which cover my ears entirely...I could always buy some cloth pads meant for AKG headphones, that would likely cool my ears...i will definitely do that if I mod the insides at all, such as adding padding inside which can apparently help adjust bass.
anyway, one thing I like about these headphones, even though they cover my entire ears, I can still hear around me...for example, right now I can hear the AM radio news across the room, while I am listening to internet radio.
the links I posted earlier have more indepth reviews, and show the frequency charts and all...and forum posts about modifying.
