SonyNW-WM1AM2 Hi-Res 128GB Walkman Digital MP3 Music Player

I love music and this is my 5th sony walkman --earlier models include a zx300 and two zx2's (don't ask).I really wanted to buy the nw-1zm2 but for that price ($3900 including tax) I would have expected a user changeable battery and software upgrade visibility (means full functionality guarantee for at least 8-10 years-having learnt my lesson from my zx2s losing some key functionalities just 3-4 years into the purchase- Sony stopped firmware update support and the walkman was stuck with android 4.2 version which resulted in many apps not continuing to be compatible with the old android version -for example spotify) and hence I know from bitter experience that sony models ( and all other brands for that matter) get obsolete due to (well calculated?) lack of support ( firmware/battery) in 4 years or so.For some reason, they put in stingy amount RAM which makes no sense considering cost of RAM is very low but i doubt this walkman has more than 4 gb ram judging by the lag it shows sometimes.I know I could probably send in my older walkman for a battery change to their center in NY and might have too but reduced functionality due to obsolete firmware makes it an unworthy pursuit.Coming to this walkman.My theory is that when you put it on and - the sound is so good that it makes you smile- the smile works on facial muscles to open ears wider and the sound improves further and thus you hear even better and better (kidding!) - seriously speaking- I noted complete separation of instruments- which then blend back together nicely, great Soundstage and overall brilliant clarity.I put on kate bush hounds of love and then some progressive house( hernan cattaneo) both flac files ripped from my own cd collection and before I knew it, I had finished hearing the complete albums - thoroughly enjoying them and with no fatigue and it was bliss. The music had my complete attention and I was fully engaged processing all the details coming in through my ears. A lot of subtle sounds that I never heard before and I have a great audio system hooked up with MIT cables so the quality of sound was obviously something.EDIT: have had it for 2-3 weeks now, feel no regret buying it. Heard it a few times (right?- where is the time to enjoy all these things) and tried 2 or 3 different ear phones as well as sony z7 over ear headphone. Felt it was underpowered for the over ear as i had it on on full volume, got loud and clear but it was at full volume- good news is that it did not distort or lose quality even while playing full volume. Tried it with sony z5 earphones with stock cable- sounded GOOD- sublime, thoroughly enjoyed the combination.Tried it JVC steel HD01 (do not remember the exact model) - Excellent, really really nice earphones for the price ($200 something) and those sounded very well paired with the walkman as well.Important note: I have several in ear phones and always struggled with some discomfort...either my ears ached, or the phones would slip out or the sound did not feel right and many times i needed to keep pushing them back in and i just passed the years thinking it is what it is. I am a 6 ft 3 guy and used medium or large size silicons/foams and then one day i tested small (never considered small might be my size). My life changed after that. Even the heavy stainless steel body JVC which earlier felt heavy in my ears -feel as if i am not even wearing them since i started using the correct size tips. Trust me, its made me love my old phones all over again and really changed my music listening experience since I finally found the correct size tips that fits my ears. I highly recommend experimenting with diff sizes of tips if you are encountering any of the discomforts i mentioned earlier. I finally got myself the JVC spiral dots in small size for all my phones except the sony z5 which came with an elaborate array of its own tips. Good news is that most of your earphones come with multiple sizes so do sort that issue out before worrying about getting a new dap.Back to the walkman-I love it. Have ordered the original case from japan for an additional 100 usd or so.EDIT: the case arrived, its real leather and the manual inside it says its special leather from Japan itself although the case is manufactured in china. Case felt good quality, the buttons have hard bits in them so even though you press the leather, the buttons on the walkman respond to pushes. I like the original sony case - worth seeking out.I put in a 1 tb sandisk card. Loaded it my music collection- all of them flac files. No particular lag even though there's a Tb of music loaded. Screen quality is good and touch screen is responsive. Spotify tested and works just fine.Edit: Its not completely without lag. When scrolling, album art is slow to show. When you turn on the walkman, even though spotify can be played relatively quickly, it takes a minute for loaded music to be accessible ( i do have 900 gb of music but as mentioned, SONY could easily have put in 8 gb of Ram for the price they are charging)Only issue I found is that it's menu locate by artist and not 'album artist' which makes it difficult to jump to a particular album considering over a tb of music even though I have about a 1000 album artists but probably few thousand total artists.Edit: found that it has a feature to sort by 'album artist' vs 'artist'- good job Sony!Battery life not really tested as I got it just yesterday. Bought from Amazon and I got one of first 100 serial numbers !EDIT: My zx2 used to discharge over time if just left in the drawer, this walkman 1am2 does not seem to suffer from that problem. I left it unused for 10 days ( was studying for an exam ) and found the charge where i left it a few days ago...so i guess that problem is not on this walkman which is great.Is the walkman itself in terms of the physical item something that is worth $1500+ maybe not- but if you include in the sum of its parts it's ability to achieve the sound quality that it can and play your music at the level that you will enjoy it at another level, I think one can bear it.Another thing, the amazon description says its made in malaysia. The piece I received is made in China (says so on the box as well as on the device) Does not mean anything but just mentioning.Will update if something comes to mind.Pros-Best in class and beyond-No Brainer under $3000 category-Excellent build qualityCons-No user changeable battery ( at high dollar prices it should be)-No firmware staying up to date visibility beyond year 4.-Should have had the case included- A little laggy -tested with 900 gb music on sandisk card -all FLAC ( no excuse for SONY not to have put in more RAM or whatever it is that would avoid that problem) encountered when scrolling through albums, the album art shows with a lag. At this price point, sony could have done a better job aka put in more RAM.- Music access not available right away when you turn on - although if that means battery is conserved- its totally excusablePS- I have a 1 TB sandisk card in my walkman containing almost 2000 albums including artwork etc. I have had no problems with operation - not even one time.If you add or delete stuff, it's normal functioning for this device to rebuild database ( longer process) . If you power on from a previous power off state, it does take a minute to read the database. This is normal functioning.

I am not sure how Sony does it but the sound from this device is Excellent.Sound signature is a bit warm. Excellent when paired with neutral to slightly warm headphones or IEMs. Warm leaning IEMs may sound too warm unless that is your preferred sound signature.Paired with a set of Sennheiser ie900s and 64 Audio u12t.

This is a big heavy brick of a device. The processor barely keeps up with the user interface - compared to the recently released NW-ZX707 it is dead slow. But the music quality makes up for it.That the U.S. model of his has the HIGH GAIN function, unlike the U.S. model of the ZX707 which is output limited. So this thing can drive headphones like the Sennheiser 600's even at high output volumes.Because of its size, weight and limited battery capacity, this is probably a device you want to use at home. But sitting in a rocking chair in the den, you will find it creates musical magic.

This is not worth the money, no bt sink, short battery life and dreadfully slow on YouTube, Netflix, etc. Plus if u returned it u never gonna get a refund from them so you’ll be playing the chat game with Amazon for some good months

This isn't for everyone if you never owned a dac b4and don't really care about personal sound then stick with your phone or mp3 ! But if you want to feed your ears then this will feed you! I do own several different brands and I love them all they all have different personality and no matter what people say it comes down to you and the head gear you use. So if you have the $ and looking for a great You can't go wrong here. Sound is great out of the box but better after 200hr on 4.4 or 3.5 jack so 400hr b4 you get the final sound out of this unit and trust me you will enjoy every minute!

I have tried 3 different devices and they have all had the problem that when I insert an SD card the player continually restarts. If a person doesn't use an SD card, I suppose it's great, phenomenal sound, etc, but it's only useful if a person has a relatively small digital library. I can't imagine that the three devices that I have had are the only ones that have this problem, so I'd recommend to stay away from this device until Sony has announced some kind of fix.

Sony siempre cuida la calidad y el Walkman, es excelente, muy buen producto.Con el Walkman nuevo su desempeño es excelente, hasta que se bloqueo, no prende ni hace nada,. Lo lleve a Sony para su compostura on la garantía que tengo del equipo nuevo y Sony me pide la Factura nota de compra con la fecha y otros datos de la compra.Amazon no me envió mi factura, ni nota de compra. Dice que mi RFC esta incompleto y mentira mi RFC, esta vigente.Sony no lo quiere reparar por no tener la factura o nota de compra.Voy a tener que devolver el Walkman con todo las molestias e inconvenientes que me provoca.Me decepciona Amazon por no tener consideración con sus clientes.Gracias por la atención a esta opinion

Definitivamente el sonido me encanta y esa es la razón principal por la que compramos estos aparatos. Lo utilizo con los IER-Z1R y es la mejor calidad en audio que puedes esperar, definitivamente el sueño de cualquier audiofilo. Este equipo no tiene limitado el volumen como comentan los europeos.Del lado negativo, el dispositivo es lento y la batería se drena demasiado rápido cuando lo utilizo con streaming por wifi.

Me gusto, tiene un buen ecualizador, mejora la calidad de sonido, pero, desafortunadamente, salió con defecto la carga del puerto usb tipo c, aparte se descarga rápido cuando estas conectado por Wi fi, buen producto, batería mala.

Si tienes unos audífonos adecuados 4.4mm balanced o un sistema de audio con wifi o Bluetooth con HiRes y usas Tidal, notarás enormemente la diferencia de las canciones hasta el más mínimo detalle. Es casi como tomar el café por la mañanas.

Si vas a comprar este DAP por el sonido y estás dispuesto a sufrir una travesía de usabilidad que está fuera de contexto, hazlo con precaución. El sonido en dispositivos como este y por el precio no lo es todo, y aunque es decente, porque de referencia no es, este es un DAP musical, cálido a más no poder ( y que para nada es malo) y que a mi gusto es un poco oscuro. Pero lo malo de este dispositivo es su sistema como tal, es absurdamente lento, con muchos problemas de ejecución, la app de música nativa de este DAP tiene problemas para leer las SD de 1 tb, simplemente no las lee, eso te orilla a buscar otras opciones lo que te lleva a vivir una pesadilla. duré 2 días con él y lo devolví, y ojo, tengan cuidado si lo quieren devolver porque el distribuidor detrás de este dispositivo ( aunque dice que es vendido por Amazon en realidad no lo es) al parecer no le gustan las devoluciones y ya tengo una amonestación de "amazon" por este detalle. Lo comento para que lo tengan en cuenta.
