First off, they came in a nice box and has a gift worthy presentation when you open it. The buds are good looking and the cable is made up of copper and black wire, which matches the flecks in the earphones.. It looks great, but I wish the cable was a bit longer even if it tangles easily. It has a bunch of different ear tips, some cleaning supplies, and a nice blue case for carrying them.
I will admit that if you listen to music like “Keith Don’t Go”, the high pitched notes on the guitar might hurt your ears. However, that song is an extreme example. Personally, I tried these with multiple amps and DACs. My preference was hearing them connected to my Little Dot MKIII tube amp. Tons of detail with the warmer sound of tubes is amazing. I tried them with an early version of the Dragonfly Black DAC and enjoyed that combo, too. With some DACs, the treble may be too bright. In that case, I tried some of the Apple Music EQ settings and the “increase bass” setting seemed to help. You can also use the “treble reducer” setting if you are highly sensitive.
Since these are pocketable, I also compared them to my Etymonic ER4P buds. The Etys have been my travel headphones for years, so I am fond of the sound. However, compared to the Canpurs, it was like a big veil went up when listening to several songs. Even with the brightness, I prefer the Canpurs to my "go to" monitors. They really just pull every note out of a song especially when using the Dragonfly DAC. The HiDizs DAC was more of a toss up because I think the Canpurs are just too bright when matched to this portable DAC. However, when EQ is employed, they can be reigned in if you are playing music with a lot of treble. In that case, they were comparable, if not slightly better sounding to my ears than the Etys.
