I can't really add much that hasn't already been said, so for a more detailed review look at the others. This isnt ment to be a professional review, it's just my experience and opinions based on it.
First what i have connnected to using bluetooth;
Samsung Galaxy S2
HP Pre 3
Sony PS Vita 3G
Acer Revo 3700 Nettop PC with a cheap dongle
I assume i would have no issue with my PS3 either i just havn't tried yet.
Some said about volume being too quiet, for me it is plenty loud enough, though i do find it does make a difference what your connected to in the first place, as some on that list were definately louder, Vita being one of the quieter ones or was when i was play MGS2 in the HD collection i have no music on my Vita to test. It was better however than my Vita constantly shouting out "Freeze" as i held up guards for their dog tags.
Had the headphones about 2-3 weeks now and not been able too use them too much due been busy at work, working 50+ a week over 6 days. I definately havn't been able to use a full charge yet, though i have been to town with them on one weekend and they were great.
Before i got these i was using my Vita earphones, and although they were often loud enough, i could always hear way too much of what was going on around me, and when your on the bus that can be annoying to put it mildly. Kids crying, parents yelling at them, all the things that turn a bus journey into a nightmare, all came through clear as day.
That first journey on the bus to town was when i knew even if paid £350 these were staying with me. Music playing at a comfortable level(probably no hearing damage caused :)) and i couldn't hear a thing, no kids crying, parents yelling, traffic or anything else. I put it down to both the noise canceling and the full cup that completely covers my ears and even though they cover completely i find they cause no discomfort and no sound leakage, it's a pleasent experience and one i plan on getting used too :)
I probably wore them about 4hrs or so that day, though for about 2hrs at a time, as i went cinema inbetween i probably had them off about 2hrs as well. Never found them uncomfortable though i'm still getting used to all the features and getting it to do talk through when i want it hardly ever happens, i usually end up pausing and lifting them off. I am hoping that in time i will be able to stop doing that.
That day i was using the Pre 3 with the headphones, pretty much emptied the Pre 3's battery but connection was solid except for one instance when someone walked past me at the bus station, i assume he had something on him that caused interferance as it was only a split second as he passed me, town had been fairly busy and had no problems til then.
I did in the past have a faily cheap pair of bluetooth headphones, some motorola on ear neckband ones, which were decent enough, but did cut out and stutter at times when i turned my head too far round, like crossing a road so it was annoying, a samsung clip one was the same when worn round me neck, turning my body too much caused it to stutter. Had no issues like that with these connection has been far more stable than my past experiences.
I listen to a variety of music from pop to rock, with some rap and hiphop inbetween, and for most of these i listen to both english artists and japanese artists. Most sounded great, some needed the noise cancelin turned off or the audio profile changed on my phone to give it the sound im used to. That is to say these feel quite balanced, unlike my friends Dre Beats headphones, so i think i get a better overall experience and one im happy with.
I don't make that much, and i'm not an audio freak i have no idea what some people are talking about in their reviews about sound quality and the highs and lows of it. I purely wanted to see what the most expensive bluetooth headphones i could find would be like, what they could do, and if all came to all and i wasn't statisfied i'd return them and go for some cheaper ones, til i either found some i liked or just settled for some that did the job. Well compared to settling for some that do the job im probably £300 worse off, but i wouldn't trade back to a cheap pair just to get the money after experiencing these. A bloke from work said they don't look much, and i was actually kind of happy to hear that as unlike Beats few people will know what these are, which makes me feel safer wearing them outside :)
As a quick list of why i would recommend;
*Solid connection compared to past experiences
*No sound leakage
*Blocks outside noise well
*Balanced sound(dont know how else to put it) not flat as such but not too heavily aimed at one type of music
*Battery is overall fairly good 10-20hrs depending on the features you use, likely wont need more than that between charges, after all bluetooth is largely for mobile devices, which will probably be dead long before the headphones are
