Beautiful, easy to follow instructions on every device


  • High Quality, High Volume Sound – ample sound for your bedroom, kitchen, or backyard BBQ. People are always surprised at the amazing volume and full range sound created by the 2 inch full range speaker and 2.4W amplifier (140 to 20 kHz).
  • Compatibility – works with any device with a headphone jack (smart phones, iPods, tablets, etc). Also functions as an electric guitar amp.
  • Fun for both beginner and advanced makers – check out the assembly video and text instructions below. Only 21 solder joints (basic soldering knowledge required). Assembly requres less than 1 hour from start to music. Recommended for ages 12 and up.
  • Made in USA – high quality product with USA sourced materials, prepared in California by two dudes who love speakers.
  • Modular Design – headers connect the speaker and battery pack to the circuit board, so you can easily try different configurations or replace a broken part.
  • Sustainable Enclosure – most portable speakers come in a plastic box, which is a problem because less than 7% of plastics are recycled in the US. The glass Mason Jar is Earth-friendly because it is easily reused and recycled, plus you might already have one at home.
  • Strong, High Quality Cord – connect your device, fits in any 3.5mm headphone jack. Use ¼” adapter for guitar.
  • Long Battery Life – 3 AAA Batteries give you about 15 hours of jam time/easy listening (not included).
  • What’s Not Included – make sure you have access to these items: soldering iron, solder, phillips head screwdriver, wire clippers, ruler and 3 AAA batteries.

    I saw this online and I’m in need of a small speaker and figured why not? It’s a great product, I had no problem assembling this. And it’s a fantastic sounding speaker!

    I’m an old geek with musical interest who knows his way around a soldering iron. It looked like a fun kit to do with my grandkids with a useful outcome. The mason jar is a cool hook

    I’ve ordered one as a gift and loved it! so I’m making a second for myself. Everything arrived on time. I really see your business professionally. Great work on customer service and genuine relations. It’s super cool that you you contacted me directly. Not too many businesses take the time to do so. As of now I’m going to spread the word for your product and hopefully some of my good friends will hop on board and get one for themselves. All in all, the assembly was quite simple and fun.

    I found out about Trash Amps when looking for the parts to make my own Mason Jar speaker. I too love to build and create electronics, and after watching your company’s YouTube videos, I knew I had to support your company. I thought the instructions were very clear. I also have a Xmas reaction when giving it to my brother-in-law. Everyone loved the product and want one for themselves. BTW I am in Portland, OR. We have a giant Weekend craft market downtown, 9 months out of the year. This product would KILL in Portland. Music+Hipsters=Mason Jar Speaker Lovers!

    I was given this as a 10th anniversary gift and it’s a wonderful idea for a gadget person like myself. I’m sure in the future there will be more gifts to be purchased from “TrashAmps.”

    Just the coolest thing ever! I saw one in my friends kitchen and was awe-struck! It was easy to order, arrived promptly, and was fun to put together. It sings happily in my kitchen every day now 🙂 I too will be getting one for my son! And Adam is a great communicator about making sure you are satisfied with your purchase. Great job guys!
