True Wireless Headphones, ZOLO Liberty [Upgraded] 8-Hour Playtime (100 Hours with Charging Case), Bluetooth 5 Bluetooth Earbuds with Graphene Driver Technology, IPX5 Sweatproof, Handsfree Stereo Calls

I have tried many different Bluetooth headphones both wired and wireless. I've had Beats x, Apple Air Pods, Jabra 65T, Jabra 45e, LG Tone Pro, Samsung Level U, JLab Epic, and probably a few more. While I know these are the newest earbuds I've purchased and technology has improved, these are my new favorites. I got these today and I am 4 hours into listening (at just under 50% volume) to them and their battery is still showing 70%. Nobody does batteries like Anker. This is great!!! I can finally get a whole uninterrupted workday of listening in without worrying about battery. These earbuds sound great, plenty loud. The treble and bass are realistically balanced without being too sharp or droning. They are super comfortable so far, I'm wearing them straight out of the box, and they fit me great. I will probably play around with the jackets and different eartips tomorrow, but they fit and sound great right now, so this might be the best combo already. Over the next few days, I will be wearing these daily, listening to different music, podcasts, and testing the call quality. I will update this review, so stay tuned. So far so good. Anker/Zolo Good job on these!UPDATE: Second day with my Zolo Liberty earbuds. Still love the battery life and how the buds sound and fit. I am returning them due to a glitch I found. While wearing the buds I found that if I raise or lower the volume quickly on my iPhone 8 the buds will glitch out, sometimes losing the sound in the left or right bud, and sometimes the buds will crash and restart. This is the only thing I’ve found wrong with them. Maybe I got a bad set, maybe Anker will somehow fix this in a software update. They make solid products and I am still a big fan.Anker Direct reached out to me, asking about the issues I had and offered to send out another pair of buds, so I could give them another try. The new buds came a few days later. I charged them up, paired them, and put them in. I instantly fell in love again. The sound is amazing. I’d been listening through my Jabra 65t’s the last week and have been missing the fullness in sound I get from the new Zolo Liberty’s. I tried to make the new buds glitch like the last pair and after really trying, I was apple to make the sound in the left bud cut out for a fraction of a second, then the beautiful sound came right back. Much, much better than my last pair. Anker, you did it. You made a pair of long lasting earbuds that sound awesome. Thank you!!! And thanks for caring about the customer and standing behind your product.

UPDATE 4/8/2019:Came back from a trip in which I was constantly using the upgraded ZOLO Liberty. Still extremely satisfied with my purchase.- Battery life: 8-hour battery life is a tremendous benefit. I very rarely bothered to charge the buds during the day, and simply waited until I got back to my place at night.- Connectivity: I have never had either bud lose connection with my phone. Very infrequently (once every few days?) the left bud goes silent for a second then automatically plays again. Not enough to concern me, but I'll update if this continues.- Build quality: I did a 7.2km hike, with the latter half in pouring rain. The buds definitely got wet from rain and sweat, and 2 weeks later I still haven't been able to notice any ill effects.-------------------------------ORIGINAL REVIEW 3/14/2019:3 days in and after heavy usage I'm still extremely satisfied with the upgraded ZOLO Liberty. I'll continue to update this review every few months or so, especially after an overseas trip where I plan on doing a lot of walking and hiking, potentially in the rain or similar inclement weather.I use my headset extensively for:1) A (not so) awesome 4 hour daily commute to and from work2) Running a few miles 2 or 3 times a weekCONCLUSION: Buy this immediately. 10/10 for me so far.PRO1) Setup: It was a snap. Charging the case took a long time due to the enormous battery size (definitely a plus), but connecting to my Samsung Galaxy S6 Edge was seamless.2) Connectivity: I've never experienced any syncing or lag issues during playback. Connecting to the earbuds is immediate after I take them out of the case or power them on.3) Sound quality: Both for music, video, and calls, it's excellent. My ears are admittedly not very refined, but the sound seems to have a deep bass and rich flavor to it.4) Battery life: The buds' 8-hour battery seems to be accurate. I had no need to charge them throughout the day, so I just leave the case at home now. HUGE bonus for me. My 14-hour international flight will also allow me to fully test battery life.5) Comfort: They sit very comfortably in my ear. Obviously this will differ from person to person, but I've never felt like they're going to fall out, even during my 2-mile runs.CON1) GripFit jackets: I can't really tell what the extra plastic nub at the top of the extra jackets are for. They don't seem to provide any extra security by preventing the buds from falling out. I just stuck with the original jacket.2) Volume: The earbuds are pretty loud by default (which is normally a good thing). But even at the lowest volume the music is still louder than I'd prefer. It's not enough to deafen me by any means, but annoying.3) Volume Controls: To that end, the lack of onboard controls is very noticeable.4) Outside Noise: The volume issue above combined with the very good suction on the EarTips means I hear very little outside noise. If someone is next to me speaking directly at me, I can only hear them if I mute or remove the earbuds. The Liberty+ comes with Transparency Technology (which allows in outside noise), so if you're not particularly observant when wearing your earbuds, keep this in mind.
