Ultimate Ears BOOM 3 is in stock at Mascom International, priced at KSh 18,000 for a portable Bluetooth speaker with 360-degree sound, an IP67 waterproof and dustproof rating, and up to 15 hours of playback per charge. Ultimate Ears is a Logitech brand, and every unit we sell is brand new and sealed. The Ultimate Ears BOOM 3 floats, survives full submersion for up to 30 minutes, and has passed more than 25 durability tests, including drop tests. See it at our Old Mutual Building store on Kimathi Street, Nairobi CBD, or order it for delivery across Kenya.
Built for university students, NGO field staff, content creators and families who spend weekends outdoors, the Ultimate Ears BOOM 3 takes music where a home system cannot go. Most portable speakers sound loud only to whoever sits in front of them. The Ultimate Ears BOOM 3 plays in a full circle, so everyone around a campfire at Lake Naivasha or a picnic blanket in the garden hears the same mix. Its fabric shell shrugs off splashes, dust and sand, and the battery lasts through a long day of play, even when KPLC cuts the power at home.
Unlike other electronics retailers in Kenya that sell grey-market speakers with no local support, Mascom International stocks the genuine Ultimate Ears BOOM 3 with a written warranty and a walk-in service desk. At Mascom International, we're seeing steady interest from buyers heading to the coast, where sea air and sand quickly ruin unsealed speakers. Customers also choose the Ultimate Ears BOOM 3 for gym sessions, house parties and Sunday family gatherings. Visit Kimathi Street to hear it in person, or order on WhatsApp and pay by cash or Lipa na M-Pesa when it reaches you.
Common Questions About the Ultimate Ears BOOM 3
How much is the Ultimate Ears BOOM 3 in Kenya?
The Ultimate Ears BOOM 3 costs KSh 18,000 brand new at Mascom International on Kimathi Street, Nairobi CBD. That price includes the speaker, its USB charging cable, a 12-month warranty against manufacturing defects, and pay-on-arrival delivery to all 47 counties. You pay nothing until the speaker is in your hands. Every unit is a genuine Ultimate Ears product, so it works with the official Ultimate Ears app for firmware updates, sound settings and PartyUp.
Ultimate Ears BOOM 3 vs JBL Flip 6: which portable speaker should I buy?
The Ultimate Ears BOOM 3 sends sound in a full 360-degree circle, while the JBL Flip 6 aims most of its sound forward. Both carry an IP67 rating against water and dust. The Ultimate Ears BOOM 3 also floats, and its one-touch Magic Button starts saved playlists on supported streaming apps. The JBL Flip 6 charges through USB-C, which suits buyers who want one cable for phone and speaker. Choose the Ultimate Ears BOOM 3 for groups sitting around it, and the JBL Flip 6 for one listener facing it.
Can the Ultimate Ears BOOM 3 survive rain, dust and a day at the Kenyan coast?
Yes, the Ultimate Ears BOOM 3 carries an IP67 rating, which means it is sealed against dust and can sit under water for up to 30 minutes. Heavy rain, sand at Diani Beach and dust on a murram road will not get inside. Rinse it in fresh water after a day by the sea, since salt can dry on the fabric. Let it dry fully before you charge it, and store it out of direct midday sun in the car.
How long does the Ultimate Ears BOOM 3 battery last, and how do I charge it?
The Ultimate Ears BOOM 3 plays for up to 15 hours on a single charge, depending on volume, settings and conditions. That covers a long road trip, a full day at the beach or an evening party with time to spare. It charges through a micro-USB port, so any standard USB wall charger, laptop port or power bank can top it up. During a power cut, a charged power bank keeps the music going after the speaker battery runs down.
Does the Ultimate Ears BOOM 3 really float?
Yes, the Ultimate Ears BOOM 3 floats, and Ultimate Ears rates it to survive full submersion for up to 30 minutes. Drop it in a hotel pool or a lake and it rises to the surface, ready to pick up. Water muffles the sound while it bobs, so lift it out to hear it properly. Bluetooth signals weaken through water, so keep your phone near the poolside rather than in a bag across the compound.
What does the Magic Button on the Ultimate Ears BOOM 3 do?
The Magic Button on top of the Ultimate Ears BOOM 3 lets you play, pause and skip tracks without touching your phone. Press and hold it to start a saved playlist on Spotify, Apple Music, Amazon Music Unlimited or Amazon Prime Music. Spotify one-touch playlists need an Android phone running version 6 or later. The button helps when your phone is charging indoors, tucked in a gym bag, or out of reach during a braai.
Can I connect two Ultimate Ears BOOM 3 speakers together?
Yes, two or more Ultimate Ears BOOM 3 speakers can play together through the PartyUp feature in the free Ultimate Ears app. PartyUp also links it with other compatible Ultimate Ears speakers for bigger events. Every linked speaker plays the same music, so you can spread sound across a compound, a hall or a campsite. Two units can also run as a stereo pair, giving separate left and right channels for fuller sound in a sitting room.
Who should buy the Ultimate Ears BOOM 3, and who should skip it?
Buy the Ultimate Ears BOOM 3 if you want a tough, waterproof speaker for outdoor trips, pool days and gatherings where people sit all around the music. It suits students, campers, gym users and families. Skip it if you want hands-free calls, because it has no built-in microphone, or if you need room-shaking bass for a large party, where an LG XBOOM party speaker fits better. For music at a computer desk, the Logitech Z130 costs far less.
