    Soundcore Liberty 4 NC Review from a techie

    Very solid earbuds for the price. The noise cancellation is very solid, given that these earbuds were under $100. I would definitely recommend these and bought some more for my dad. The noise cancellation is very good for the price, but of course it isn't perfect. The audio is pretty solid and you can customize sound preferences in the app. The battery life is also very good and can last for days and charge relatively quickly. Overall, I really enjoyed these headphones. I just wish the noise cancellation was a bit better but these are probably the best you're gonna get at this price range. I was also hoping it would be waterproof since I am a swimmer but these are details that probably wouldn't be as important to the average customer.

    Good but sub par feature integration.

    They work good, they are loud headphones that have great sound quality as well. The eq settings work pretty good. The noise cancelling is good for low sounds but the higher toned sounds still come through. The transparent mode is okay, but you can still feel the natural noise cancellation of the earbud tips. No matter what size bud I had in the headphones eventually fell out my ears. Don’t be fooled by bad reviews on this thing because the sound is great but the features is where this thing loses the quality. Its features are not up to par with my first gen AirPods Pro. Also the sound leaking on these is loud, everyone next to you can hear what you are listening to (that’s how loud they are). They have a sound leak compensation feature built in where it’s supposed to stop the sound from leaking out but this feature does not work as good as it needs to in my opinion.

    Great headphones except.. no notifications

    I really enjoy using these headphones. The ANC works great. I use these in a noisy environment and they remove so much of the background noise. Love that. Sound is great. The battery lasts about 8 hrs with ANC on. The cons are you don’t receive notifications such as texts and phone calls on these from my iPhone. That is why not a 5 star
