Just awesome!
I'm enjoying this player very much after installing a custom firmware!

The custom firmware really makes this player come alive. I thought it sounded awesome with the stock firmware, but it's nothing in comparison to how it sounds now!

Best purchase ever!

Love the Sound Quality, Built Quality Top Notch!
This is a another great product from Sony!! I have been a Sony Fan since 1980s with Cassette Walkmans, Mini Disc, CD players. I really enjoy the sound quality, simplicity of the interface and software!. I gave it an excellent score, but i have to say its not perfect. Sony, these are some of my wishes, Pls put a backlight on the bottons, as sometimes, u want to listen in the dark, and a visual lighted button would be loved by many, make the screen a little bigger relative to the size of the player, and use a universal interface.. like a USB C????.. Otherwise. this is a great product and im happy with this!.By the way, i ve had this product since 2018, and im only writing this review now.. 12/2/2020.

Signature player, Signature sound
Sony WM1A

I was considering Sony WM1A and ZX507 players to upgrade from my good old A17. I first bought ZX507 but returned it later due to poor battery (my A17 still can beat that battery in 2020), and unnecessary android mess. Then I bought WM1A and I was never so happy with my music.

Here is my opinion:


Feels premium with leather back, gold colour walkman logo and metal like NFC logo. The entire aluminium block feels good in hand. It is a delight to look at the screen, which is big enough (4”) to satisfy most music listeners. This big player devotes its aluminium chassis and components for one main purpose, to reproduce quality sound. Battery is solid lasts me a 2-3 days without worrying to charge.


Sony has come a long way to improve its already fantastic Walkman OS and WM1A reconfirms the fact by being glitch free and seamless. The OS is a breeze to work with and comes with Equalizer, Tone control, DSEE HX, DC Phase Linearizer, Dynamic Normalizer, and Vinyl processor. I enjoy on-screen time more on WM1A tweaking the sound using all technologies. Digital peak metre, spectrum analyzer, and analog level metre are fantastic addition. This is where WM1A felt more of a Walkman than ZX507.


If I have to describe in short, the Sony WM1A sounds more natural and original to music creator’s intent. It still has the magic Sony sound signature but with enhanced clarity and realism. I have pushed the limits on volume but never find the player to be struggling neither leaving bass behind nor the treble went irritating for my ears. The sound stage is expansive and instruments could be easily distinguished. If I identify any shortfall, I tweak the sound to my personal liking using equalizer and tone control, however they both are mutually exclusive. I have little to complaint in the sound category. I heard people saying it might not have enough bass for bass lovers, this made me a bit nervous before buying, but I have no complaints with bass its plenty and precise. Paired with logic 7 in car audio, it redefines music at each note. It is a genuine Walkman that holds its ground well in 2020.

WM1A - Oh, the sweet clarity of the sound!
I already had a good HiFi system, but I knew that I could improve the source and wow, this Sony WM1A blows me away. The depth and clarity coming out of my Parasound and SVS set up was incredible and then I plugged in my Fostex TH900s and found even more unbelievable clarity.... I can hear every breath, every string of a bass vibrate. The WM1A is solid engineering and easy to use and transfer HeRes music to, and I could not be happier. It even sounds pretty amazing through LDAC bluetooth. Very, very impressed

Great Sound.... and control....
I have tried so many DAPs , A&Ks, FiiO’s, Onkyo, and others and none of them have the sound quality of the WM1A.... this DAP still beats off all the latest DAPs when it comes to sound and almost 3x the battery life of any other DAP...
With my CA Solaris and EA Cleopatra cable this WM1A is audio nirvana....
