Great headphones or earphones under $20

I have been thinking about ways to modify the earpads on the HAS160 to velour. Unfortunately changing to velour will probably decrease the bass though. I don’t know what the difference is between the older HAS150 and newer HAS160 flats. I have the HAS160.

The Sony MDR-E828LP was a pleasant surprise. Years ago I had used the E848, however they didn’t fit my ears too well. The E828 was $20 for many years. It is only relatively recently that it is under $10. I was surprised how much bass it has, and how efficient it is 108 db/mw and 16 ohms. I like the right angle plug. Since I liked the E848, at under $10 I thought the E828 was worth the risk. I was pleasantly surprised. The cord is rubberized,anti tangle, which is nice.
