1st things 1st I guess ; I tip my hat to the Guy who Designed the O2 & to JDS Labs also for making it ready built. Now I don't know the Guy who came up with this O2 Headphone Amp but if I did I would certainly shake his hand. I don't say this lightly but here it is then ; This little Headphone AMP is quite simply put the best sounding Headphone AMP I have ever heard, PERIOD ! You add in the fact that I imported it into the UK direct ready built by JDS Labs for just under £100 including a UK PSU for recharging & I guess that possibly makes this little...

Had these Little Gems nearly a year now & felt compelled to give a Review (My opinion) of them. Best start at the beginning then I guess ;) Since I 1st seen these a couple of years back I somehow knew I would end up with a pair as looks wise they are indeed Little Gems :D Once your box arrives = you'll get the typical Monster Fancy Box & inside that lots of other Fancy Pouches/ cases/ Tips/ SuperTips... Oh & since it's Miles Davis you'll get a CD & Booklet etc etc... I cannot fault the Presentation type box & supplied goodies that you get with these...

Hi, I've been patiently waiting for my 535Ltd's to get a good few hours run in (this includes the stock cable & an upgraded 3rd party cable purchased from eBay, OFC Silver plated copper with Oyaide Plug). I'll just be giving you my thoughts on the 535 reds & try to refrain from too much into towards cable choice etc... Unboxing ; The Shure Red's Packaging was nothing special & thus would probably lead you to think there's nothing special inside... Not like say Unboxing something like a set of Monster Miles Davis Trumpet Buds where the packaging is...

1st off I bought these so I'm not 1 of those reviewers that get things to keep if they give reviews etc... To the IEM's then ; Here in the UK the cheapest price for mine's (control talk version) is about £250 these days I think. I bought them 2nd hand from a friend, receipt & verified real, but beware that IMHO if you see these too cheap to be true = they will be fakes as Monster headphones are the most copied ever I think. Now I'm not going to bore you to death with long winded words & so called "Audiophile" terms those kind of people like to use...

BTW I'm from Scotland so I paid £555.00 for mine, not $555.00 THXU :)   1st off lets get this out the way then eh ; Baterry life isn't great & TBH with you it was never ever going to be great unless they made it bigger by giving it a higher capacity battery making it bigger, so you kind of know this from day 1 that loud amazing sound comes at the cost of battery drain ;)   Now where to begin hmmzzz... FLAC/ WAV Playback is just outstanding with your chosen cans, I'm not going into sound descriptions as each to their own as each have...
