Pros: These sound better than my HiFiMan REO Kylin. Not even close. An education for me. I will think long and hard before I spend considerably more on an IEM than what I paid for these. I bought a second pair.

Cons: These fit in your ear differently than every other IEM I have had. I can not use these for most activities as they will dislodge from my ear. My ears are too small or the Baldoors too big. But, for just sitting and listening they are exceptional. I can walk with them. Just have to securely reseat every so often. They will not give you the very deep bass you get from cans. Isolation is not their forte.

Other Thoughts: For this small change give them a try. I would be surprised if you are not surprised.

Pros: worked perfectly. copied 1.4 TB in 4 hours, USB 3. Does not need to be plugged into computer. It even identifies the target disk as Samsung though it is WD. Thesource disk was Samsung. So it clones in the strictest sense of the term.

Cons: it was supposed to flash a red light when done, but mine did not even though everything is there.
