Battery life is great and can be on standby for a very long time

Amazing sound quality, great battery life, converting album covers are easy using the Sony's music center

Battery life is phenomenal.

Excellent battery life rated at 30 hours of play, depending on the codec being used (and Sony is generally correct with these; assume easily about 25 hours, and your Bluetooth headphone's battery headphones will be out long before the player)++ Sony-specific Bluetooth technology ("LDAC") TRIPLES the data stream rate over traditional Bluetooth up to 960kbps, supporting wireless transmission of Hi-Res audio (amazing)++ Traditional 3.5" headphone jack so you can use most any wired headphone you wish (check the manual for any compatibility

Beautiful sound, long battery life, great design and solid build quality.

Battery life is pretty good but using Bluetooth drains it considerably faster than a wired connection

I list it as a positive.

Still not as warm and as open as I remember the Fiio (even via bluetooth) to be but much better than my iPhone obviously.
