I too tried to reuse my X3 some time ago. I had abandoned it because dual boot didn't work for me either. I also think the battery is dead: I can't recharge it any more. If the microSD with rockbox is missing charging doesn't work? If I have to buy a new battery, can you tell me where?

It's my same question! I'm selling my BTR5 for this reason: I have problems with the bluetooth connection when the BTR5 is in the same pocket as the smartphone, or even when they are in two different pockets but separated by 20cm (and on the same side of the body). I'm looking for a worthy...

Not at the moment. I am monitoring what is being written by users about the Shanling UP5, but it is still too early to put it on my 'wish list'.

My current BTR5 also suffers too much in bluetooth connection and I'm about to sell it and look for a more efficient replacement in this aspect. A pity because the sound is really satisfying.

I have been quite satisfied with my BTR5 for some time. I like the sound I get with this little DAC / AMP, but I have very big problems with bluetooth. I use the BTR5 with two devices: my main smartphone (an old Honor 8 Pro) and a smartphone that I use only as a music player (an old Samsung...

Thank you to all for answers! Yes, exactly! Beautiful this ones! The DJ35AG is the new model and it costs 5$ more than the DJ35A. Is it worth spending more because it is a decided improvement over the previous model, or is there not a big difference?

Talking about adapters... Can you recommend a good 2.5 balanced to 3.5SE adapter? Thanks so much!

Sorry if I come back to a question I have already asked ... Looking for good headphones "portable" and with balanced cable I found the V-Monk Lite, but with a balanced 2.5 plug only the 120 ohm version remained. Does BTR5 manage them well? Do you consider it a valid option? I own both the V-Monk...

Looking for a cable usb-c to usb-c to connect the btr5 to my phone, I found this one mentioned in this thread many posts ago: https://www.amazon.it/dp/B01LONPUM4/ref=twister_B06XT2FR5Q?_encoding=UTF8&psc=1 Someone can tell me if is a good choice? There is something better (but in this price...

For this "test" I use my favorite "portable" Koss KSC75. Conntected directly to the phone they sounds good, but with the BTR5 connected via BT and aptX HD the sound is worse... Yes I think so... I test the BTR5 also as a USB DAC connected to my pc and used my modified AKG K701 and the sound...

Finally my BTR5 has arrived (after a wait of almost 2 months). Unfortunately I discovered that my mobile phone (the Honor 8 Pro, in fact) does not support the LDAC codec, despite having been updated to Android 9.1 in the meantime. When the BTR5 is connected to the mobile phone, the screen...

Thank you for answers. So let me change the request. Another headset that I love very much are the Grado SR80: unfortunately the ones I had are broken and at the moment a new pair cost more than my budget. The SR80s are not very small, but certainly more transportable than other full-size...

A few weeks ago I purchased the new DAC/AMP Fiio BTR5. Unfortunately, given the current times, the Italian importer is in difficulty both in receiving supplies of new products and in shipping them, so I'm still waiting to receive it. In the meantime, I read some reviews and I follow the...

I am still waiting to receive my BTR5 (I think that all shipments to my country have slowed down), but while waiting I ask you something. For the installation of the USB DAC drivers on a Windows PC, the official manual recommends turning on the device and installing the driver WHILE the device...

yes, that's what I found too (I just mentioned the site name in my previous post). I have no idea if the site is reliable. I will find out next week when I receive the Btr5 ...
