I love my Beyerdynamic dt 770 250 ohms, especially since I got them for $4 at goodwill. They are the best audiophile headphones I own.

Only Update thus far is that Amazon is being slow.

For anybody wondering, I think these are the Polaroid PEP14 series. I have just ordered the PEP14PNK on Amazon for like $9 New old stock, in order to sanity check with a new pair and see if mine are Unicorns or if this is just an accidentally fairly decent old line of ear buds.

The vocals are definitely the stand out feature, very clean and pleasant sounding. The stereo separation and overall soundstage is wide and lends itself really well to Live performances such as Hell Freezes Over by The Eagles. The high end is surprisingly good and the mids are really decent and definitely a step above many earbuds in this price point. The lows are definitely not super amazing but they do exist and they are not at all muddy and have a pretty tight representation here. The FIIO BTR5 is definitely doing a lot to help these little earbuds, but still definitely not anything I was expecting out of them. Pleasantly surprised is an understatement.

If you have the money to write a blank check to a shop, they are happy to take your money.
