I got these two days ago to replace my Beats Studio Wireless for my iPhone 6S Plus. The audio sounds really balanced and high fidelity, it's great detail to the sound and it feels really laid-back.
I got these as they are pretty much the only high-end bluetooth headphones out there that do support AAC for iOS devices. Why companies like Sennheiser and others only support aptx and not AAC is beyond me when they know that there are no other high-end phone on the market remotely close to the sales numbers of iPhones and I highly doubt that people who purchase mid to low-end Android phones would ever consider headphones in the high-end price range.
Did also test out the BeoPlay H8 and to be honest, they don't sound that good to me. I suppose they are rather high-fidelity and fairly detailed as well but those over-tuned bass is really killing it for me. It's funny how the BeoPlay H8 lives more up to the "Beats are ****ty headphones with a lot of bass" than the Beats Studio Wireless ever did. The bluetooth also seemed to have some questionable range and stability as well which I find horrendous considering the price. I did not like the fact that they were on-ear instead of around-ear either. Even though the pillows of the H8 is comfortable as hell you will most likely start to get irritated ears after long use anyway as your ears simply won't enjoy having something pushing onto them for extended periods of time.
I would say that BeoPlay H7 is superior to the BeoPlay H8 in about every way possible. The audio is vastly superior and is not spoiled by over-tuned bass. The bluetooth connectivity seems to have much better range and stability and they are more comfortable due to the around-ear design compared to on-ear of the H8.
There are some drawbacks with the H7 though.. The microphone is a complete joke, it's pretty much useless unless you are sitting in a dead silent environment. The microphone seems to manage to pick up background noises better than my actual voice, which its impressive and quite frankly horrible considering the price of these headphones. It becomes quite clear that B&O simply tossed in the microphone for the sake of having the feature on the box without them ever trying to make it actually useful in any sensible way. But the same goes for the microphone of the H8 so it seems like this is something B&O is doing on purpose.
Another drawback is the lack of active noise cancellation. I don't mind not having it, as I tend to not enjoy the feeling you normally get from using active noise cancellation and most headphones tend to behave fussy at times if you are moving while having such a feature active. But the passive noise cancellation is not that great with the H7. One would figure as they are around-ear, they should be rather capable of cancelling some noise but the pillows don't really provide a good seal around your ears so noise are leaking in quite easily. It seems like B&O have been afraid of them not being comfortable so they have made sure that the pillows don't push hard on your ears at all, thus making them not making a good seal at all. Good in terms of comfort, not that great when it's the only kind of isolation they've got.
This problem becomes even greater when you take into account the next drawback.. These don't play that loud, at least not using bluetooth to my iPhone 6S Plus. The combination of lacklustre passive cancellation and the fact that they don't go that loud makes it so that they are somewhat less usable on the bus between home and work compared to my Beats Studio Wireless.
And one last thing I'm afraid of is the leather on the band of the headphone. As I tend to use them when I commute they might get somewhat wet due to a little snow fall or small amount of rain. This was never an issue with the Beats as they are made out of plastic, but with these I'm afraid the leather will turn really nasty after a short while as leather tend to colour when exposed to water.
But after all I think B&O have done a great job with these. If they could replace the dreadful microphone and give them active noise cancellation like the H8 they would have knocked it right out of the park. Why they decided to not include active noise cancellation is really beyond me. Seems like a horrible decision, one they must have made just to continue to have the H8 as a "higher-end" edition compared to the H7 for some stupid reason.
The only pair of bluetooth headphones that can match these would be the Sennheiser Momentum Wireless (v2), it's only sad that Sennheiser decided to really cripple those with the lack of AAC....
