I needed new headphones so I got these and the JBuds J3 Micro Atomic In-Ear Earbuds (purchased them for $19.99 now they are $9.99) and planned to test between them and return one. My quick response is that I'll keep the Panasonic. Bass, treble, and mids seem pretty decent. Fit in the ear well and for the $6 I spent, great price. The JBuds have slightly better sound but aren't as good for working out but not good enough to pay an extra $14. So if you want to use your earbuds while running/working out, get the Panasonic. If you're using them to just relax/walk around, the JBuds are slightly better and work it at $9.99. 

Question: How is the quality of the sound?
Answer: slightly better sound but are n't as good
