The BB-777 is built for the ones who remember when a boombox wasn’t just a speaker—it was the centerpiece of the block, the soundtrack to break battles, rap cyphers, and late-night sessions. We brought back that same presence and energy, keeping the look true to its roots, but packing it with Bumpboxx power, clarity, and wireless features for today. It’s a piece of the past reimagined for the present—made to be carried, shown off, and felt, just like it always was.

Mixtapes. CDs. Radio. Playlists.
Music has changed formats over the years, but the feeling never changed.
BB-777 lets you play it all again. Drop in a cassette, load a CD, tune the radio, plug in with AUX or USB, or stream from your phone with Bluetooth.
You can even record your cassettes directly to USB and bring those old mixes into the digital world.
Music from the ’80s lived on cassettes and CDs: where countless mixes and recordings were captured.
BB-777 brings those recordings back to life.
Record audio from cassette, CD, or radio directly to USB as clean WAV files, turning a retro boombox into an easy way to digitize your favorite recordings.
Old mixes, rare tracks, and personal recordings can live on long after the tape stops spinning.

"Finally got it today! Sounds great, clear clean sound. Love the details and loaded with features. Love how the battery charges when plugged in. Shipping took about 40+s day. Only one issue with the unit is my CD player won’t eject the CD. Reaching out to customer service later tonight. Thank You for bringing this dream to life."
"Excellent Retro System, love the looks and quality. !0+ all around. Only concern was with the feel of the Volume knob. Doesn't feel as solid i'd like. But everything else is spot on and great. Would motivate anyone to buy."
"Man this thing is amazing. The sound. Everything works great. I can't get over the size of it and how heavy it is. Highly recommended 5 🌟 🌟 🌟 🌟 🌟. No complaints. Just shy of 4 months. We'll worth the wait. You guys are missing out on a 80's retro feel. Old-school is back. And it's awsome"
"It does just about everything I ever dreamed of. Bringing back the retro feel that I remember from the '80s. It plays well, it sounds great, it bumps loud. The only reason it did not get five stars, is because it claimed the records a wav files, says it right on the home web page in the description as well, and was the main reason I purchased this. It does not. It records the MP3. That was a letdown for me."
"The BB777 has great build quality. The attention to detail to the original is all there. Nothing about it feels cheap. I didnt know that it plays cds until I got it. It sounds great and plays clean upto max volume."
"Received the silver BB-777 box a week ago and I am blown away. This thing has the guts of a thoroughbred. Dusting through all my old cassettes and CDRs its a walking talking nostalgia machine. Shoulders gonna be SWOL from carrying this thing around. Good thing I'm old enough to have a little land cause everything in my surrounding area is getting sonically punished! Well Done Team"
"Got my BB-777 last week, Happy Camper!!! Sound is crisp and smooth and you can even hear the special lossless, Spatial tracks coming through from Apple Music in “3D” from Bluetooth! ( I can at least… 😉 ) Very smooth, tape mechs works great, CD sounds wonderful. Looking forward to making many digital files from tapes and CD mixes and other media sources over the years, getting it all digitized…Gonna use the tape deck plugged into the computer for a ZOOM Meeting that I attend. The possibilities are endless, with the amount of options on this beast. Thanks for creating this one-of-a-kind product!!! ✌️❤️🚀⬆️ 🔈🔈🔈🔈"
"Massive Boombox that brings you back to your B-Boy days. Loud volume with a Bold Personality. Definitely one for the Bucket List. Rob Owens…. Salute"
"I am satisfied with this bumpboxx, the sound and quality of this boombox is excellent. This thing is a beast, I have had it bumping since I received it a few hours ago. I am interested in a black one now."
