The NWZ-A844 MP4** device adheres to Sony Walkman's consistent pursuit of high sound quality and high image quality, not only supports high-quality PCM linear files**, but also is equipped with S-Master digital functions used in home audio and video devices to reproduce CD-level sound quality performance.

In addition, its excellent sound quality, stunning display effect, support for ** output and other good functions, once again shows Sony's strong position in the field of audio and video.

9 Sony D50 and the like.

The sound field is slightly wider horizontally and narrower vertically, the three frequencies are balanced, the low frequencies are relatively good, the vocals are slightly prominent, and the high frequencies are slightly darker

1All A844 is the last generation of high-end after all, the new series of machines and earbuds will definitely press the previous generation, it is said that A844 has been discontinued, now is to buy one too little one, you go to ** on the look is still there, but you have to hurry. Personally, I think the A844 is a more classic and collectible machine.

As for the new A864, it also has unique advantages,But the promotion is not an ear,Next, I'll take A844、A864、X1050 respectively in the bottom noise、Sound field、Vocals、Medium frequency、High frequency、Make a simple comparison on low frequency,Give the landlord a reference。

Noise floor: Although you can basically ignore the problem of noise floor when listening to songs, you can still clearly feel that the floor noise of A864 is close to 0, in contrast, the floor noise of A844 and X1050 can be felt when you turn on or off or listen to pure music.

Sound field:864The sound field feels wider than A844,More complete,And 864The sound field enveloping feeling is better,It's the feeling of surging up from all directions,And 844It's relatively concentrated in the middle,Some can't stretch,864In the process of interpreting the soundtrack,It feels more prominent than 844,And the position is clearer。 X1050Although the size of the sound field is about the same, it lacks a sense of envelopment, and the atmosphere of listening to songs is not strong enough.

Vocals:844The vocals are obvious to everyone,Full of magnetism and charming voice,Tuning in the front,It is also very pleasing to the ear,It is a great weapon for listening to the vocals,864The vocals are relatively x1050 in the front,Relative to A844 in the back,It's quite a bit of the golden mean,It sounds more comfortable,It's just relatively less decorative,It seems more real。

Mid-frequency: 844's mid-frequency is relatively full, X1050's is average, in contrast, A864's mid-frequency appears fuller, with a thick sound floor and a bit rough.

High frequency: 844's high frequency is more gorgeous, rich in details and particularly round and soft, very malleable, 864's high frequency is more straightforward, relatively simple and a lot, not so rounded, sometimes it feels a little too sharp, but a864's detail performance is also not sloppy, very clear.

Low frequency: 844's low-frequency volume sense is just right, the cohesion is very strong, there is no slightest divergence, the elasticity is also excellent, A864's low-frequency volume sense is slightly more, the low frequency is strong and powerful, the cohesion is also excellent, the elasticity is also OK, when listening to the bass effect in the song, you can feel that the low frequency is very strong, there is a little bit of fist to the meat taste, the dive is deeper, and it is also very clean, and it can be retracted freely.

Overall, the sound style of A864 tends to be less modified, more tough taste, and a noise floor close to 0 also brings a more pure sound, while A844's direction is relatively soft and emotional. The sound of the A864 maintains the level that Sony's high-end machines should have, but it is still unrealistic to say that it completely surpasses the A844 or X1050 machines, and it can only be said that their grade is maintained at a level.

Yes, that's how everyone charges. The Sony Walkman A844 continues the charging tradition. The charging hour can reach 80%, and it takes 3 hours to fully charge.

Because Sony's battery is a lithium-ion rechargeable battery (the memory effect is very minor), it does little harm to the machine.

Personal suggestion: Regardless of whether the battery is used frequently or not, it is best to charge and discharge the lithium-ion rechargeable battery every two or three months or so, so as to ensure that the memory effect of the lithium-ion rechargeable battery has a minimal impact on the battery.

The quality of Sony's stuff is absolutely ***.

In addition, the A844 is so beautiful, I want to buy it.

As for the seat charger you mentioned, it depends on your economic strength, and if you have money, you can buy one. **For 399rmvb, I personally don't think it's necessary, it's better to bring a notebook when you go to other places.
