Here's the only tech you should be looking at when buying Bluetooth headphones:
AAC/AAC+ support: mandatory for playing off iPhones and iPads. Apple has made their choice when it comes to their wireless codec of choice, and it is AAC. Some companies try to hide their inability to support AAC under generic terms ("we have A2DP support, and it may include AAC yada yada"). That's a no. Case in point: Sennheiser Momentum Wireless does not support AAC.
AptX support: mandatory for playing off desktops/notebooks (including MacBook; Apple notebooks support AAC, but some AAC-only headsets can't pair in AAC mode, my V-MODA, for instance) and, if you're lucky enough, from your Android phone.
W1: a proprietary Apple technology, unlikely to be licensed to 3-rd party vendors. Amazing for battery/power management (AirPods, etc.), does not have anything to do with sound quality (again, Apple prefers AAC).
Utility gotchas: does your new headphone come with an analog cable? Does it have a remote, can you make calls with it? Can you play music when charging? Can you talk when charging? Do you know what chip they have and can you google it? Did they test it with smartwatches (requires a really good antenna)?
If the headphone lacks both AptX and AAC, only buy it if you're locked with an Android phone that can't do AptX even with custom firmware.

Bluetooth 5 will have 2x better bandwidth, but it is unclear if it will have anything to do with the sound quality. We are supposed to have a new codec that would be almost lossless, but I don't exactly see vendors raving about that. We'll see.
Right now we have AAC 256kbit as an Apple standard (and that's precisely the quality of the stuff you buy off iTunes), AptX to match that quality. If AAC catches on with more companies and sources (and it should), soon your source won't need to recode files at all, they will be transferred to your headphones as-is IIRC.
So as a buying advice, headphones' ability to support AptX or AAC is pretty much binary, yes or no. There are variations of AAC support, but I'm not an expert in that, unfortunately.

"I found that aptX makes a noticeable difference in quality, even while I'm "background listening". Doing some a/b testing, I couldn't pick up any major differences between aptX and connecting directly to my phone. Personally, I feel like this comparison was like 320kbps vs flac. I can hear a slight difference, but not enough to justify going a more expensive route.
Tacking on some details about aptX: aptX and aptX Low Latency both deliver "cd quality" audio (48kHz / 16bit LPCM), and the LL decreases the en/decode time into something like the 1-3ms range so you don't see a desync between audio and video (e.g. wireless audio while watching netflix). aptX HD pushes the quality a bit higher to 48kHz / 24bit LPCM"
