Let me get this out of the way - I am an audiophile. A proud, card-carrying member of this sometimes dysfunctional community. I care about sound quality more than others and I make no apologies for that. However, it can be exhausting at times to fuss over sonic nuances in equipment and in the music itself. Sometimes, I just want something that's fun and engaging and, dare I say this, NOT audiophile-y.The EarFun Air Pro 2's are just what I need.Full disclaimer: I own the EarFun Free Pro and the EarFun Free Pro-Oluv Edition. Both are good ANC earbuds but the original Free Pro's have an over-emphasis on the bass and treble while the Oluv Edition are tuned almost flat and are more balanced but sound lifeless with no energy. Not to say that anything is wrong with them but they lack soul and passion. The Air Pro 2's strike a nice balance between the two in my opinion. There is still a bit of emphasis in the bass but the midrange is more prominent and the treble is smoother but can still be very present.But, wow, these Pro 2's are so fun to listen to! Here's the quick rundown on the frequency spectrums:Bass - it really punches hard when required but they are not absolute bass cannons - which is a good thing. For modern pop, rap, EDM, there's good weight and authority to the bass. For other genres like rock, jazz, folk, and even classical, the bass is definitely present but doesn't draw your attention away from everything else going on in the music.Midrange - this is probably the best thing about the Pro 2's, even though they are a bit recessed but nowhere as recessed as the Free Pro's. Vocals, solo instruments, etc, have a more front and center presence. A good recording will present the mids quite well but even if the recording isn't the best, the mids will still come through ok.Treble - I admit I enjoy a really good and well-extended treble. The Pro 2's do extend well into the upper regions but with some recordings, they can be a little zingy, but that's more because of the recording. Otherwise, it's really decent and brings life and energy to the music without much sibilance.The Pro 2's have three modes - normal, ambient, and noise canceling. A long press on the left bud will toggle between them. Normal mode can give you all the noise reduction you need passively but NC mode will reduce outside noise more dramatically, mostly in the lower frequencies. It does boost the bass a little bit more and pushes the sound more to the front which reduces the openness a little but I can see where some might like that. I use them in NC mode when I cut the grass and while some of the mid-frequency noise will come through, they reduce the low rumble of the mower very well. This is really good considering that the Pro 2's don't insert into your ear canals. Impressive.Lastly, the Pro 2's do not have an app that allows you to control the aspects of the sound and tailor them to your own preferences. This may be a deal-breaker for some but to me, it kind of makes a statement that EarFun is confident in the way they tuned these and that it should please most listeners. I would say that EarFun is getting better at defining and developing their sound signature and what they have here is very, very good! Fun-sounding, better balanced, cleaner...I say, well done!To me, these are the kind of TW earbuds that you just pop in your ears and just have fun with your music. When I'm not fussing with my collections of headphones from Beyerdynamics, AKG, Grados, or Sennheisers, I just put these in, especially when I'm out and about, about just enjoy the music! The EarFun Air Pro 2's are amazing for what they are. Sure, I can pick these apart with a fine-toothed comb but why? These are not audiophile earbuds. They don't have to be. They're fun, dynamic, and fairly balanced. Throw in good touch controls and great battery life, these are my guilty pleasure "reference" TW earbuds.As an audiophile, I have no shame in owning these!
