You'll need to find a product that's right for you, however, you can never go wrong with a company like Anker who takes so good care of its customers...
------------
Design and build quality excellent. No complaint. Durability we'll find out sooner or later.
Battery life also exceptional, great job Anker. Call quality is great. In terms of noise cancellation, this is a closed design earphone without active noise cancellation, if you cant understand this, dont bother reading the rest of the review :)
Pairing with iphone xr was a disaster but I got it work using the "putting them back to back" trick...
My real issue is with the sound.
My current wire headphones: Sennheiser HD598, Bose Soundtrue On-ear, Sennheiser IE80, Denon C710K, Creative Labs Aurovara Air (which I absolutely love more than any other), and Apple EarPods.
My current wireless headphones: Airpods Gen1 (I lost one earbud which is why I bought the Anker); Sony WI1000X which I use for air travels.
I'm not comparing this $89 pair True Wireless earbuds to the IE80s, which is obviously not fair. I'm also not comparing this with the Aurovara Air, which has a different design.
The problem is that I dont know what I can use to compare. The resolution seems to be fine, with "fake grains" which is common in over-engineered headsets or speakers. The compression of bluetooth obviously didnt help either. The sound stage, well I dont know how to describe it.. it sank into the bottom of the ocean and can never be found. The real problem is that it doesnt matter which profile I pick out of the app, I couldnt get out a pleasant sound. Is the Apple Earpod superior when it comes to sound quality? Not really. However, it produces decent sound that you can listen to for hours and not feel like going insane. I think same thing applies to the BeatsX which has terrible sound but doesnt make you uncomfortable. The Liberty Air 2, unfortunately, didnt achieve that. When you try to get good sound of a budget headphone by over engineering everything, it usually doesnt end up well.
The bottom line is - I'm keeping these because they are so comfortable and easy to use and have an in-ear design - which is what I absolutely need for my 3 - 4 hour daily commute - I dont want to spend $250 for the new AirPods pro and this is excellent for its price. However, I still want to write this review because what Anker (one of my favorite companies) claims to be "rigid diamond-coated drivers produce sound with flawless accuracy" is simply not true. The accuracy is terrible which is ok for this price point, just use a different angle to highlight the product.
After much frustration with Bose SoundSport Free earbuds, I decided to cut my losses and look for something that would meet the following criteria:
1) Frustration free Bluetooth pairing
2) Excellent sound quality
3) Excellent battery Life
4) No Connectivity Issues/ Connection Drops
I can happily say that the Anker Soundcore Liberty Air 2 wireless earbuds have met all of the requirements that most other products fail to meet. My experience with the Bose SoundSport Free earbuds was often met with issues and compromises that made me wonder how a flagship product from such a reputable company ever made it to the market.
Successfully pairing the Bose earbuds was a constant battle. When successful pairing was finally achieved, one earbud would often disconnect. This forced the user to go through a complicated "reset" procedure in order to "fix" the issue. Poor battery life for both the storage "charging" pod and the buds was also something that plagued the earbuds. Total discharge would often occur over the course of two days, limiting the use over long term use. Sound would often lag when watching videos on YouTube, and worst of all "by design" only one earbud would work when paired to the PC.
Thankfully, the Soundcore Liberty Air 2's do not have any of these issues. Pairing with my Samsung Galaxy S10+ was effortless, without any syncing issues or video playback problems. Both earbuds stayed in sync at all times, and did not require any "resetting" or waiting for the starts to align in order to work successfully. Pairing with the PC on Windows 10 was as simple, just like the initial pairing with the phone.
Sound quality by no means makes these the holy grail of earbuds for any self proclaimed audiophile, but they are excellent in terms of providing fine tuned sound and noise isolation.
I would consider the sound quality to be superb, especially at this price range. I can without hesitation say that sound is marginally better than the pricier Bose earbuds ($225). Comfort is subjective, but the smaller size and choice of 5 silicon inserts leaves these as the clear winner over the Bose earbuds.
The optional app that Anker provides is pretty simple, offering an equalizer for further tuning to carter to whatever sound style one may prefer. The "Hear ID' offers additional assistance by running you through a simple "hearing test" in order to develop a personalized sound map for both left and right earbud. The app also allows the user to remap touch gestures so that custom functions can be assigned to meet your exact preference. I found the app to be quite intuitive without much bloatware, an approach that's rather simplistic with focus on just what's needed.
Overall i am very satisfied with the Anker Soundcore Liberty Air 2's. Providing an objective review on earbuds is a very difficult, if not an impossible task. Personal bias and preferences are bound to influence any review, no matter what anyone says. Forming a baseline of reasonable expectations is the best way that one can establish realistic representation of the product being reviewed. Issues often plaguing devices in this segment were not observed with Liberty Air 2's, which is something that a user would expect in this price range. Sound quality, comfort, and overall user experience would exceed most reasonable expectations in this price category. I would not hesitate to recommend this product, especially if it's one that you are considering over a pricier unit.
TLDR: In the wise words of Jim Cramer: BUY BUY BUY!
Top reviews from other countries
With these, however, your custom EQ or HearID is lost and the earbuds reset back to factory default/stock sound every time you charge them in their case. This means that if you want to use your earbuds with say, your TV or another device, you first have to pair to your phone, open the Soundcore App, re-apply your desired EQ (or your HearID), then disconnect from your phone, then pair with your other device. IF at any time you put your buds into the charger, that EQ setting will get removed (or HearID will be turned off) and you have to repeat this process again.
I've tried 2 of the Liberty Air 2 and they both do this. They won't retain your custom EQ within the earbuds. I've asked on the Soundcore community and I've asked their support and they both tell me this shouldn't be the case.
The sound on these is EXCELLENT, however very sibilant (high frequencies too powerful) out of the box and will hurt your ears after about 30 mins of listening. So, I like to use the Bass Booster EQ, or the Treble Reducer and THEN the sound is VERY good. The bass can punch hard but without being overbearingly boomy like on too many earbuds and headphones these days. When you dial down the treble the sound becomes quite nice and flat, but still with lots of dynamics and punchiness. THIS is why having your EQ stored inside the earbuds is a great thing but these won't do it.
Pros:
Great sound IF you use the EQ.* These are bright (too bright out of the box for me) but VERY clear and have excellent separation imho.
Fantastic fit and comfort with lots of eartips. In fact, only Soundcore includes XL eartips that will fit my ears. L from most manufacturers do not work. When you get a nice seal, outside sounds are reduced passively to a great degree.
GREAT controls that can be customized! And once the controls are set, they are locked in unlike the EQ. They are very responsive, THE BEST CONTROLS I've used.
Great design and feel. These feel premium to me and very solid along with an IPX5 rating.
Mid:
The battery life is about 6.5 hours at 40% volume for me which seems lacking as I've had older buds that do 8-11 hours. I use buds all day to that amount of time is rather disappointing. The volume you use doesn't seem to affect it much as I've tried 30% and even 80% volume and 6.5 hours is what i get. The one annoying thing is that the "battery low" voice comes in very early, usually with over 30 mins left on the battery. It then repeats every 10 mins. The voice is VERY loud and startling so you kind of have to charge the earbuds and can't run them down because that voice is so annoying and persistent. I'd rather had 1x battery low warning with maybe 10 mins left.
So for me battery is barely acceptable, but compared to what many expensive brand names offer, the battery life is actually better (some earbuds costing 4x as much only give 3-4 hours of battery which is appalling). Considering that these are so compact, 6.5 hours is probably quite good.
Cons:
*The biggest one is that you have to re-open and apply your custom EQ (or turn on HearID) every single time you use these after charging. Every time. This makes using the earbuds with anything other than your phone a huge hassle (it's a hassle even if you just use your phone).
The sound is quite piercing at default, very sibilant. This can mostly be remedied with the app/EQ but again, you have to do this before every single use.
If it wasn't for the inability to save EQ settings in the earbuds I would probably give these a strong 4.5/5. especially on sale. But having to re-apply EQ settings before every use I personally give these a 3/5.
If you are somebody that likes the default sound and never use the EQ, and 6.5 hrs battery is enough, then these are a must buy.
Edit: I contacted Soundcore and they were very helpful and available. After having the same issue with my second pair they were willing to help me out and so I have to give them a 5/5 for support.
