by Anker Space A40 Auto-Adjustable Active Noise Cancelling Wireless Earbuds, Reduce Noise by Up to 98%, 50H Playtime, Hi-Res Sound, Comfortable Fit, App Customization, Wireless Charge

These earbuds arrived on time with exceptional packing. The sound is great and the battery lasts for days. I used them primarily for listening to music while walking, sleeping, or occasionally at work. They stay in no problem and fit pretty close to my head. I can sleep with him while on my side, but not for a long period of time. I have owned several earbuds, including a couple of versions from Apple. For the price, these compare very well and I have no complaints..

I like being able to connect to multiple devices simultaneously. I like being able to control it in an app. It has a fewer less options than I have with the Liberty Pro 4 set that I have. The Space A40 are low profile and seem to fit well, but they also work their way loose often. I wish they would stay put better. I wish I could slide the control between full transparency to full ANC (like with the Liberty Pro 4), The A40 has 3 distinct settings, where the Liberty Pro 4 has 10 settings you can slide between.

Sometimes won’t charge one ear bud but otherwise great.

Purchased these in May for general use as I wanted something close to my Samsung buds+. They are the most similar buds to the buds+. Recently started using these for sleeping and noticed that they never charge to 100%. The case charges to 100% but the left bud charges to 97% and the right charges to 95% but never 100%. Also, be warned that the 10 hours of play time cited in the item description is under the most ideal circumstances you can get up to 10 hours of play time... Using these for sleeping with ANC set to adaptive and all controls disabled playing at the lowest possible volume, I get about 6 hrs before the buds wake me up with a loud "battery low" warning, which isn't ideal, but I can usually fall back to sleep much faster than when I initially go to bed. Overall I would give 4 stars because they fulfill all of my expectations for ear buds in general use case scenarios. I'm disappointed that they don't fully charge and that the battery life is nowhere near what it is advertised at, and that I can't disable the low battery warning. These are not "sleep buds" but I most frequently use them for sleeping and they don't fall out. I usually fall asleep on my side but whenever I wake up I'm on my back. They don't cause me any ear pain laying on my side and I would say my ears are fairly normal in size, but normalcy is all relative to the individual. I was able to use the standard ear tips that came pre installed on the buds so I figured I'm "normal".

Easy to set up and has a device locator. I love these headphones. They are comfortable and I love how well they cancel the noise. The noise canceling works even if there is no music playing. I never have issues using them for phone calls. These are better than their previous model, as they will work with no disruptions as you change which pod you put in. They last a whole work day without having to put them back in their case. The case stays charged for a long time too. I charge it once a week and use them every day.
