1. comfort - they did seem to hurt a little bit in the beginning but I found that if you adjust the flexible hook tips slightly outward, the pain was gone.2. sound - good to great for BT. Obv not as good as some wired buds/headphones.3. BT connectivity - I did find connection drops when phone is in back pocket, more so when in left back pocket. Seems to be a same problem with other BT i have owned like the Anker Soundbud Curve. It also does not auto connect if you are turning on the X2 from off state, meaning if you turn off the X2 via long button press vs. putting them in charging case to turn off and removing to turn on.4. Battery - my last point about the BT connectivity ties in w my issue on the battery. I seem notice shorter battery life between the case and the headset when I put the X2 in the charging case instead of turning off via button press. ie if I run the battery out of the buds, it lasts about 5 days at 1.5 hrs/day so about 7.5 hrs and the base seem to have about 3 charge cycles for the buds so this worked out to be about 20 days total. When I first started using the X2, I would put the buds into the base after each use and only got about 10-15 days before base and buds were drained. Also, in running the battery down in the X2 before charging, I noticed the right side would die out before left side. Android (Samsung) BT connection shows an estimate percentage of battery remaining and right side usually dies with the left side showing at least 40% remaining. Overall, battery life is very good though compared to the non-hook style buds. Will be contacting Anker and update my review.Update 11/16 - true to their always excellent customer support, they responded both to my posted question and email inquiry within 24hrs. They sent out a replacement unit instantly and just received yesterday. I'm upping from 3 to 4 stars for their response and support. I will update again after testing out the new unit and report back if 1st was just a fluke w battery issues. Nice work Anker/Soundcore! Thank you.Update 12/18 - I did find new replacement unit to have similar faster battery drain on the right vs. left. My guess is possibly b/c the right side is the BT connection to phone/player and the left BT connection is through the right side piece so you end up with faster battery drain on right. Just my guess. This is not really an issue if you regularly put the units in charging pod when not in use vs. my using up the battery before recharging. I have since gone back to regularly putting into charging pod after use and the replacement unit does seem to last about 20 days w 1.5-2 hr use each day. I'm upping from 4 to 5 stars for Anker/Soundcore's excellent customer service and support and overall build + sound quality. Given the long battery life of unit and pod, the battery drain issue is not that big of a deal.

UPDATE 11/2022:I feel like I had an experience with these headphones that might be worth updating my review with; Generally, playback on these earbuds is solid -- Sometimes, though, I would experience drops/a "speedup" effect, that was making me think they were starting to malfunction. I bought a new pair of earbuds... And experienced the same issue! Turns out, a specific spot in my commute home just has a horrible connection, or is just too crowded with people, and interferes with the BT. They snap back to how they're supposed to be once I get closer to home.This is a relief to me, because these are still my preferred earbuds. Everything about these has still been great and I love using them.---I gave Anker a try for these because I've bought from this brand before for other things (usually batteries), and am always satisfied with the quality - I'm glad to know that they make quality earbuds as well.For my purposes and for my level of pickiness with audio - I just like for things to not sound tinny and to get loud enough to block out other sounds - they are great. I know there's more nuance to audio that I can't comment on, since I'm not a professional or anything. I just know that they treat me well for my needs, as far as how they sound.The design is comfortable, fits amazingly in the ear once you get used to kind of twisting them around. That brings me to the primary reason I purchased these, coming from simpler bluetooth earbuds (Soundpeats Truefree+) - I needed earbuds that wouldn't pop out and roll away during a workout! So far I've not had them slip even the slightest bit, even after jogging and doing a bunch of jumping around. Glad to know that I can go back to focusing on my form instead of having to smush my earbuds back into my ears every few seconds.One thing I want to comment on for people in the reviews who say they do not get loud - I recommend NOT using the volume adjustment buttons on the actual earbuds, as they seem to have a volume setting independent of the one on your device.First, press the right earbud's volume button as many times as it will go (it'll give you a little trill when it won't go anymore), THEN adjust your phone's volume to something comfortable. It's much better, in my opinion! If you try to adjust the volume using the earbud, it won't observe any changes on the device, which leads me to believe it's some sort of software thing unique to these earbuds. I do not prefer to adjust my audio's volume via the earbud anyway, so that is not a big issue for me.Overall, I'm 100% satisfied by my purchase.
