Choosing between digital audio players comes down to a clear trade-off: do you want the Sony NW-A55's named Hi-Res Audio features, or a compact Bluetooth MP3 player with FM radio and voice recording? The two devices serve different listening priorities, and the listed-price gap is $129.10.
Quick verdict
Choose the Sony NW-A55 Walkman if your priority is its specifically named Hi-Res Audio playback, S-Master HX digital amplifier, DSEE HX upscaling, and headphone jack. Choose the Bluetooth-compatible MP3 Music Player if FM radio, voice recording, Bluetooth listening, and a lower listed price matter more.
Neither choice covers the same buyer brief. The Sony is centered on its audio-processing features and Walkman identity, while the Bluetooth MP3 Music Player emphasizes portable everyday functions.

Product notes
Sony NW-A55 Walkman

The Sony NW-A55 Walkman suits listeners who are choosing around audio-focused specifications rather than a basic playback brief. Its description names Hi-Res Audio, an S-Master HX digital amplifier, and DSEE HX upscaling for compressed files. The headphone jack, 16 GB capacity, and Micro SDXC compatibility also give the model a defined music-library setup. The limitation is straightforward: the listed price is USD 148.00, and the condition is open box. That makes it less aligned with someone whose priority is FM radio or voice recording. Select the Sony for the specific Hi-Res Audio and processing features, not simply because it carries the Walkman name.
Bluetooth-compatible MP3 Music Player

The Bluetooth-compatible MP3 Music Player is the practical match for a shopper who wants several portable functions in one small device. Its description calls out Bluetooth connectivity, FM radio, voice recording, and support for music and other media, while the title explicitly identifies it as a lossless portable player. The 1.8-inch screen and USB 2.0 connection add useful, concrete details for everyday handling. Its limitation is that the feature emphasis is on MP3 playback and convenience extras rather than the Sony's named audio-processing system. The new condition is another reason to choose it when a straightforward, low-cost player brief matters more than Sony-specific playback technology.
Final choice by use case
- For headphone-jack listening and the Sony's library setup: Choose the Sony NW-A55 Walkman, with its headphone jack, 16 GB capacity, and Micro SDXC compatibility.
- For a compact interface and USB 2.0: Choose the Bluetooth-compatible MP3 Music Player, which lists a 1.8-inch screen and USB 2.0.
- For the lower listed price: The Bluetooth-compatible MP3 Music Player is the clear match at USD 18.90 versus USD 148.00 for the Sony.
- For Sony's named audio processing: Choose the Sony NW-A55 Walkman and its Hi-Res Audio, S-Master HX, and DSEE HX feature set.
