I have received my UTWS5 two days ago, on the 30th of December, at long last, after waiting for it for more then 20 days! Purchased from FiiO's official store on AliExpress, they did their job right, but it got stuck on UK Customs for, like, 10 days.
I am very happy I got it and very excited using it!
It drives my 7Hz Timeless flawlessly, they fit inside the case perfectly and they sound great! Amazon Music Unlimited + some YouTube Vanced, aptX Adaptive on my phone. The fit on my ears is perfect, it's like the Timeless are glued on my ears. Everything works great! Bluetooth connectivity is excellent, in my house. I can leave my phone downstairs, in my office, and stream steadily upstairs, in the bedrooms. When it comes to call quality, I had a few WhatsApp calls with family and they can hear me crystal clear, like I am in the room next to them! I can hear them perfectly clearly, as well. I have not tried a call outside, yet.
Sonically, I am perfectly fine, truly satisfied, it can drive the Timeless really well! I have not tried, yet, my TRI I3.
I am really happy and satisfied from my purchase! This combination beats, by far, anything else I have recently tried, like the Melomania 1+ (I still own the M1), the Technics EAH-AZ60, the FiiO FH5s, all of which are now returned and fully refunded.
Thank you very much,
@FiiO !!
