This is a fine music player but it is also a missed opportunity. No Bluetooth or Airplay is a glaring omission. The file management software is also pretty poor as you're never quite sure what is about to be transferred and there's no means of formatting or defragging the internal hard disc.

I bought this Sony to store all my music , selling or giving most of my CDs. Sound quality is great paired with a pair of Boston a26 speakers. The down side There are not many hi-def down loads avalible in the UK Both the control app (android) and the transfer software (windows) need a lot of work on them. The transfer software fails to update automatically and I have start the transfer in the manual mode and control app often fails to find the Hap-s1 Get the software sorted and you would have a top class product

I do really like what Sony have produced with this HDD player, however certain aspects have left me very frustrated. The file transfer software is very basic and failed a number of times. I 'phoned the helpdesk in the end who were helpful. I had over 4,000 tracks to transfer and left it running overnight, so don't expect anything too quick. It then took a good part of the following day to get the album art etc. Had to turn off and restart on a number of occassions for it too eventually work through the admittedly large number of tracks. Finally, it seemed to have done a very strange thing - the Number 1 track appeared to be missing from a great many of the albums. I eventually twigged to what had happened when I saw there were over 400 tracks the Unknown Artist subdirectory. I am now labouriously working through trying to get them back to where they belong - whether this is a weakness of Gracenote, how they were stored on my computer or the HAP-S1 who knows? But the sound is good, the interface also. The 'phone app seems to work very well.
