Tembo Trunks TTBlue Portable MP3 Player Headphone Speaker Amplifiers, Blue (Pair)

Years ago I saw this product on kickstarter. The idea was neat, I knew it was not going to increase volume up 90db as discribed. The sound driver used is still crappy ipod ear buds and the product is made of silicone (absorbs sound). The seller provided the product in a timely fashion and the product is in good shape with original packaging. 5 stars for the service, -1 star for the itemsame performance.

excelent

These sucked, I used my these for my phone and my phone has a louder speaker.
