[One (M8) General] Viper4713:
Sense 7 ROMs for M8, yes pure stable, but I will be honest with you ARHD is the most unstable right now strangely, mike abandoned the M8 for now in favor of the M9, he may be back some time soon.

The 5.0.2 Sense 7 Ports are closer to a true Sense 7, they contain almost all the files from Sense 7 base, only thing Sense 6 about it left is drivers and such to make everything work 100% like audio and radio(4G), now the 5.0.1 ROMs are less closer to true Sense 7, they have many Sense 6 libs and such left behind and its mainly only focused on the apks, like Settings app and Sense Home for example, this is why the 5.0.1 (base without mods) ports don't have the flashlight toggle in QS because the SystemUI.apk still have Sense 6 elements while the 5.0.2 ROMs have full sense 7 SystemUI.apk.

When Sense 7 releases there wouldn't be any visual changes compared to the 5.0.2 ports at all, however it is believed that when its finally out it will come with Android 5.1, so HTC might make some changes but I am unsure, however there will be a couple Android changes at that point like swiping up on a heads up notification to hide it(without fully dismissing), but the current 5.0.2 ports will feel exactly like the M9 does, so nothing is missing about it, and of course its still the M8, so HK works and all that, so it feel like M8 for sure rather then an M9 port where something could potentially be missing.

As for earphones, I am an audiophile but I spend a bit more money then that, you wouldn't believe what you could be missing until you get some real high end headphones, now I understand that more expensive doesn't always mean better but in some cases it does, I mean some headphones are not $299 for NO reason, I my self wouldn't go under $79 but that's just me, my build quality on my $212 earphones is great, you know what you should try out? go get some Klipsch S4's or S5's, they are cheap for what your paying for, I assure you they will sound better then the ones you have now, you always have a return policy so try it out for fun if you want, put it on a credit card so no real money is being spent yet :p

For Audio its not just about lows and high, mids, sound stage, clarity and many others are also very important, so currently you may enjoy your set up, then you try something real high end and then realize that your current setup may have muddy lows and artificial highs, also separation is important as well, for example, you could have a huge bass note booming in your ear but yet at the same time it won't overlap any other frequency AT ALL so when a bass note happens the singers voice will not appear to get quieter or distorted, it will sound like the bass note is coming from a separate sub woofer in the room while the mids and highs are playing from a dedicated speaker but in reality you just have earphones/buds on! You can say you have this now but yet again its one of those things you have to experience to realize your current setup either doesn't have it or doesn't have it enough.

Please understand my respect to you here, I am not bashing you but just saying there is an other level you can achieve here you have never heard, its kind of like 2D to 3D and other dimensions you may not know exists :p

I have expensive Polk Audio Speakers in my car, I also have $249 computer speakers and yet my earphones still are much better then both of them, its to a point I have had these earphones for 2-3 years and I am still shocked by them, its also mind boggling to me how these earphones/buds can sound better then a studio or a real speaker for that matter.
