    I was planning a ‘NYC girls trip’ and wanted to get 6 custom mason jar speakers as a special gift for my friends, so I emailed Adam and he made each Mason Jar Speaker with a custom name engraved on the wooden top. My friends LOVED their Amps! The rechargeable battery is great and easy to recharge, the music never stops 😀 Thank you!

    I picked up a copy of the free Outdoor Adv. magazine (I know the family that puts it out -nice people).
    I saw a picture of your product in there and it really jumped out at me because I can use it to play music on my apple gadgets AND plug the guitar in, I play guitar all the time. Also, we can a lot of fruit and vegetables, so the mason jar caught my attention 😉

    i was at the maker faire years ago and you were making amps out of old soda cans…I remembered your company so i was searching online for trash amps. i purchased the mason jar speaker from your website for my friend who is a musician. i thought about buying the diy speaker kit, but i know my friend doesnt have much time for doing projects. so i ordered the one that is ready to play music immediately. and i am stoked that it is rechargeable. i love the idea of filling it with some objects… maybe a whole pile of cocktail monkeys. ..

    I was googling mason jars because my sister has a thing for them and I was trying to come up with a unique Christmas present for her. I do everything to avoid buying stuff made overseas by faceless corporations. Thanks for being so prompt in getting the speaker in the mail. My sister is going to love it. Take care and God bless.

    This is my 1st Anniversary gift to my man. Good news – I’ve received the speaker here in Brunei, half way around the world! I showed the speaker to my niece, and she said “If I were you, I won’t give it to him or someone else. I’d just keep it for myself!” Haha. True indeed, when I look at the speaker I feel like I’m insane to give this an anniversary gift. I should have bought for myself too!!! Hahahaha. I tested the speaker yesterday. I was eager to know how does it sounds like. So I plugged my handphone and played a song…..Oh My God, I can’t believe it can sound that amazing. Looking at the size of the speaker it really blown me away. I gave the speaker today as the anniversary gift and he loves it! I should’ve taken a video and show it you guys his reaction when he first saw it. It took him a minute to figure out that the mason jar is a speaker! Haha. Love to see him all smiling again because he was recently sick for a few weeks. Thank you for the unique invention, you guys! We both love it very much.
