Cqtek posted a review of the xDuoo X3II digital audio player. From the review it sounds like this is a neutral sounding DAP and is a significant improvement from its predecessor. Priced at around $160 it should be a contender in that pricing segment. Although, you can pick up some really great 1-2 year old DAPs that are around the same price.
Pros – Number of features (Bluetooth, DAC, Hiby Link, Line Output, Bidirectional USB, etc.). It is a very versatile product.
– Size and weight, in line with its predecessor.
– Screen size.
– Initial firmware with just a few faults.
– Gapless from the beginning.
– Battery life.
– Great sound.
– A firmware with Rockbox is now available.
Cons – The layout of the buttons is original but not too ergonomic.
– Shortage of accessories, not even a case comes.
