JDS Labs Headphone Amps In Disguise. Summary This is a really cool idea a headphone amp disguised as a box of mints! But the cMoyBB v2.03 is not a novelty item by any stretch of the imagination it actually sounds immense and each one is hand built with care and precision. Here is a quick customer review Ive pinched from the JDS Labs site.. I received my cMoy BB amp this afternoon! I just had to take a moment to let you know how wonderful this little thing sounds! I have headphone amps ranging from $150. to $2000. dollars and this little amp rivals the best of them! The sound is great without any break incant wait to get 50 hours on it! Thanks for making this fine productI will probably order a few as Christmas gifts soon! Im glad to have a cMoy to add to my collection and I have a feeling it will be the go to amp over all the other ones! Thanks so much!
