(NEW) Panasonic RZ-B310W ErgoFit True Wireless ANC Earbuds

I've been a part time audio engineer for decades, so I have a pretty good ear. Overall they sound pretty good for under $50. The 2 issues I encountered are: 1) They don't get loud enough. I used them while I was mowing my lawn and the noise cancelling gets rid of some of the background noise, but not enough to immerse a person in their music if there's something loud in the background. 2) They don't go deep enough into the ear canal. In ear monitors need to couple with your ear canal in order to stay in place and reproduce low frequencies well. This made them very light in the bass and if I tried to boost the bass with my phone's EQ, it would start to distort at "high" volumes. If they went about a 1/4" deeper it might take care of both problems. I'll probably look for different ear pieces to attach to these that will go deeper into the ear canal.
