soundcore by Anker Liberty 4 NC Wireless Noise Cancelling Earbuds, 98.5% Noise Reduction, Adaptive Noise Cancelling to Ears and Environment, Hi-Res Sound, 50H Battery, Wireless Charging (lightblue)

I bought these as a Renewed product for £67 and I've been using them about six weeks now before writing this review. The first thing to say is that they came in a sealed box as new with quickstart leaflet, cable and a full set of silicone tips. Also you get free product return for one year which is much more than for a normal new product with Amazon. There seemed to be very little risk, so what's there not to like? There's a really great app that comes with the earbuds that helps you get the most out of them. Firstly there's a fit-test tool that helps you find the right tip and a good seal. A good fit is essential. Secondly the HearID tool helps you find the best sound for you by doing a hearing test followed by preference selection. This come up with a equalisation curve that can be further modified by adding in your preferred listening style. After quite a bit of fiddling around I was able to get a sound that I was happy with and compares well with my Bose QC35 phones. I also turned on LDAC sound quality, but whether it makes much difference when streaming from Spotify, I'm not sure. Straight out of the box they are probably not going to give the best sound, so using the options in the app is really needed. As for noise cancelation, I would say very good for the price. They works very well for reducing the sound of jet roar and the noise of a train, but less so for the sound of people chatting and not as good as Bose for that. But, hey, look at the difference in price! Probably using foam tips would improve the isolation. I found the transparent mode seems to introduce hiss so it's not my favorite mode. Overall I think they are amazing for the price. I found the comfort to be great, no problems there. Connectivity has been rock solid, no drop-outs and they always connect instantly. The battery life is excellent too and would easily last for a long-haul flight to the far east. I'm using them with a Galaxy S20 phone. Overall I have no hesitation for awarding 5 stars especially as I only paid £67.

I happen to be a big fan of Soundcore/Anker headphones and the phenomenal sound they create. My original Liberty Air 2 I have just retired after almost 7 years use (with alternate ear tips). I also bought some Liberty Air 2 Pros but these would never sit comfortably in my ears and just fell out. I took a chance on these and love them. Finally Soundcore have managed to create an ear tip that grips my ears and stays in place. The noise cancellation is good (if you need that sort of thing) and the sound and HearID function (for deaf people like me) is excellent. The earphones make taking phone calls much clearer and more understandable for me. The music quality is great and there is plenty of manual/mapped EQ settings to adjust the earphones to just how you like them. UPDATE: Whether from iOS updates or a device update the Bluetooth is working so much better now. The NC has been tested on tubes, trains, aeroplanes and in cars and is working superbly. These are an absolute 5 star earphone.

These earbuds do an amazing job of noise cancelling. I had the Soundcore Life A2 earbuds but I lost one earbud a few weeks ago so I needed to replace them. I saw this set on sale so I bought them. I also Have the Soundcore Space One and the Soundcore Space Q45 headphones. Compared to the headphones these earbuds block a lot more noise than the two headphones and a lot more than the LIFE A2 earbuds. These earbuds sound really good too and have good battery life. But I may have a defective right earbud because it only seems to hold a four to five hour charge with noise cancelling turned on. I'm not using LDac. Just standard sound with noise cancelling. The left earbud will keep on going a good while after the right earbud powers down when its battery goes dead. This is after leaving the earbuds inside its case charging for 6+ hours. I know both are charging because when I open the case they both flash white ad I have the case fully charged too. I am a big fan of the soundcore headphones and earbuds. But I'm slightly dissapointed that the right earbud doesn't run for the time thats advertised. This could just be one of those factory defect things though. It happens with everything.

Sound quality

Dreadful! Around another other phones the link between the earbuds and my iPhone is impacted. It’s like someone alternately switching them off so impossible to listen to anything and also makes you feel sick.

Very nice for the money. Good sound.

Excellent audio quality but poor call clarity. When on calls, I've been told to stop using them since the quality makes it sound like I'm in a big room or driving a car. Only one other person's voice was found to be reasonably acceptable out of the two that took part the test to make sure it wasn’t just my issue. In conclusion your face form, size, and speaking or pronouncing speed may all effect this? In conclusion. Very good for music, not so good perhaps terrible, depending, for phone conversations!

Fantastic till yet. Loved the prod.
