How is the durability of these compared with the RE400?

The RE00 was much better IMO. These don't sound nearly as good, even for $10

Does anyone know how the Plenue 1 sounds compared to Hifiman's HM 802s? I'm considering switching to the Plenue.

That's weird. I just got a replacement and it still only lasts around five hours.

How do they sound open compared to the he400i?

Does anyone have issues with the battery life? My HM 802s only lasts around 5 hours before dying.

Is the Plenue V comparable to the Hifiman Supermini?

How does the Plenue D compare with the Plenue J?

You mean the reset option in settings or poking the little hole below the power switch?

Recently my HM650 stopped reading my SD card files, and I have to update the media database every time I turn it on for the files to show up. Does anyone know how to solve this? Thanks.

Does anyone know where to get a case for the HM650 (Hifiman player)? Preferably not from China.  Thanks
