B015 – Front Stereo Signal Amplifier Booster Headphones Speaker Amplifier Headset Dual-Audio SourceProduct description:
You have a line level signal source (TV audio, MP3 player, Video game, mobile phone, tablet, computer, record player), but desire louder sound or bigger volume?
A powerful signal amplifier receiver or volume control, you may need a long line connecting TV audio and the receiver on the other side of the room to provide high gain through any line level signal source, allowing longer cable operation or requiring “buffer” to amplify the lower volume. You may use it between the line level signal source and power amplifier as a signal amplifier, 3.5mm + RCA port matches almost all product interfaces.
The product improves the sound amplification and reduces ground noise by controlling the signal, and it has large dynamic range without produce cracking. It controls output volume through a sensitive volume knob, the output of the headphone interface can drive 16Ω-600Ω headsets, and uses AC9V transformer for power supply to ensure full power.

Glitter Bomb
Color: Glint Rainbow
It gets ALL over the place and doesn’t stick all that well. Neat idea but it doesn’t work the way I would hope.

Cute bottle, great product
Color: Sparkling Pink
My daughter has been in to all things glitter. Most recently her makeup and skin care. Shes been looking for hair glitter. While helping her search I came across this spray and thought the bottle was too cute to pass up. The quality is great, she sprays it in her hair and it lasts all day. She can also use it on her skin for added sparkle. Surprisingly for a loose glitter it sticks really well. Some specks may transfer but not much.

Really lovely
Color: Glint-Rainbow
Got this for my toddler as a celebration gift for getting rid of her binky. Only big girls get to be sparkly. I also use clear coat on our nails and spray with however much glitter we feel like at the time and it's very cute. It is not adhesive, it's just loose glitter. If you want it to start on your hair I'd suggest light hairspray first immediately followed with the glitter. It's a very fun little bottle.
