*1 A portion of the memory capacity is used for data management, so the actual usable capacity will be less than this.
*2 LPCM conversion is used for playback.
*3 Copyright-protected files cannot be played back. Not all encoders are supported. Files larger than 4 GB (2 GB for APE only) cannot be played back. This product defines a high information content sound source as one that exceeds CD (44.1 kHz sampling, 16-bit quantization) and DAT specifications (48 kHz sampling, 16-bit quantization). (The "HR" mark is displayed for sound sources with high information content.
*4 Depending on the Bluetooth device connected to the device, the communication environment, and the surrounding conditions, noise or sound may be generated or interrupted.
*5 A Bluetooth profile is a standardized set of functions for each Bluetooth device.
*6 Audio compression conversion method.
*7 Abbreviation for Subband Codec
*8 When receiving FM radio, the cord of the connected headphone acts as an antenna. Please connect and use wired headphones.
*9 Effective only when listening with wired headphones (Bluetooth listening is not available)
*10 The outside sound capturing function makes it easier to hear the surrounding sound. However, this function does not make all sounds audible. Depending on the surrounding conditions and the type and quality of the sound being played on the Walkman(R), you may not be able to hear the surrounding sound.
*11 Please check the support page (https://www.sony.jp/support/walkman/)
*12 Battery life for Bluetooth connection may be up to 50% shorter depending on the content format and settings of the connected device.
*13 Battery life is a rough estimate for continuous playback in the default setting. Since the battery is slightly drained even when the device is in playback standby mode, the duration will be shorter if the device is in playback standby mode for a long period of time. Duration will vary depending on volume, usage conditions, and ambient temperature. The duration will be significantly shorter when the screen is displayed. When sound quality settings are enabled, the duration will be about 50% shorter than when all settings are "off". When the Hi-Res Streaming function is enabled, the duration will be about 40% shorter than when the function is "Off".
*14 Compatibility with all microSD memory cards is not guaranteed.
*15 Longer continuous playback beyond the rechargeable battery life requires recharging the battery during playback.
*16 If the number of songs transferred to this product exceeds 20,000, the product may not operate properly.
