Customer Reviews
Los tengo hace más de un año hasta la fecha funciona sin problemas, siempre se los muestro a mis amigos y les terminan llamando la atención, nada que decir me gustan sus productos, espero con ansias los próximos Liberty 5 Saludos desde chile....🇨🇱
I'm a big fan of the brand and they stand behind their product. I had the liberty air 2 and upgraded to the liberty air 2 pro. I returned them, feeling they weren't the upgrade I was looking for, not worth their price over the air 2. Finally when those liberty 4 came out I went for it and was happy with the upgrade. The sound quality is great, the fit and confort is great, and I was surprisingly amazed with the squeeze controls. They are very responsive, and no accidental touches. I much prefer it over touch controls. The only complaints I have about those but are minor complaints is that over time the opening and closing of the charging case has scraped the finish on the back of the Earbuds (see picture). They didn't leave enough gap there for the lid not to touch, though it is light, it definitely left a mark. Multi point connection doesn't work with LDAC turned on. And lastly, the wind noise reduction is useless. I was pretty disappointed about this as I had been blown away in the past with this feature on much cheaper Earbuds from a competing brand.Still the best wireless Earbuds I've used so far and looking forward to what the brand will come up with next.
I've been with soundcore since the OG liberty, About every year and a half if not longer when I finally wear down the sturdy Liberty series I eventually have to pick up a new set. For some weird reason I always try to go for the new fancy set and always end up taking them back and going with soundcore. Once again You guys knocked it out of the park! I can't wait to see what you guys come up with next!
Hey, couple of months ago I've bought and posted a review form my Liberty 4, you've sent me a firmware update which improved ANC quality fir that thank you.
Then I found a really frustraiting issue with my earplugs -> I cannot answer or hang up calls from the earplugs i.e. in order to answer a call I should pickup the phone and manually answer, which makes me loose calls. I do not know if it is from the firmware update or from something else but can you pelase fix this
I am sending you img with firmware values.
One more thing:
I am having Airpods Pros also and they have very nice feature when the phone is ringing just say Answer and call is answered :O Mind-blowing right !
I lost my Liberty 3 Pro and now time for new model.
