Pros: natural sound, clear mids, deep bass,comfortable
Cons: highs r not crisp, soundstage do not match elder bro hd555 or hd595.
i bought these headphones for $50 without bill(discontinued everywhere). before burn in the sound was little harsh when amped with fiio e6 ,e11,e7,e18. so i used the bass settings on the amp.. well after 20-30 day wow the mids and highs improved a lot and the bass was tighter and deeper then my hd439.. the mids were crisp but i like the hd 595 more as the soundstage is much wider with highs r well balanced. i was shocked when i compared them to my hd700 . the sound signature was almost the same with right amount of bass. well hd700 r some other league still at this price the headphone could match its sound signature and the amount of bass.. we really cant compare the mids , highs the soundstage.. it would be unfair for the hd515. the wire is very long(3 meters) . i use them with my tv too.. and i was watching fast5 yesterday was so amazed by the the sound quality. well i use fii0 e18 with my tv.
sennheiser provide a 3.5 adapter which is very handy with portable devices. i bought the cover from sennheiser for $10.. (i feel that they should provide hp bag). they r open headphones. i really dont know what ear technology do..i know the theory part of it but when i try to compare it with the non ear technology hps like hd439 ,hd205, px100 ii..well i am a sennheiser fan boy. i will buy beats if sennheiser launches it.. all the beats lovers these r beasts against the beats studios and detox. my frnd r noobs they buy beats and skullcandys so i get a chance to listen to them and make fun of them.. for me the hd515 has warm sound.. these can be amped to gv brighter sound. hd515+ fiio e11=hd595+fiio e6 imo.
well i wanted them as i am a headphone collector and music enthusiast. i know they are not available anywhere now.. so grab the fabricated or the new ones (without the bill).
hd205<hd429<hd238<hd239<hd438<hd439<hd515<hd595<koss ksc75<px100ii<hd598<hd650<hd800<hd700<beyer dynamics tesla t1.. i hv many amps as i never sell the product i buy.
imho i really love the sound of ksc75 and px100 ii..i am not comparing it with iems i think they r really different when compared to onear or over headphones.
