BOSS HORN
THE TRAIN HORN
THEY WON'T FORGET
150dB portable train horns with wireless remote. Powered by your drill batteries. No installation. Ready to blast.
Most-Asked Questions
How do I choose the right horn for me?
Pick the horn that runs on a battery you already own.
Runs on your existing tool batteries — the same packs as your drill or impact driver. No new batteries to buy or throw away: cheaper for you, easier on the planet.
The brand changes nothing about the horn. Every horn uses the exact same internal and external parts — so a Quad is a Quad and a Dual is a Dual. They sound and perform identically across every battery brand; you give up zero sound or power.
No cordless tools yet? Go with DeWalt®, Milwaukee® or Ryobi® — they give you the widest range of tools to buy later on the very same batteries.
Which horn is the loudest?
Our loudest sit at the top — here's how the lineup ranks:
1. Boss Series — our newest (2026) and most refined; it reworks the older Extreme design and fixes its weak spots. Its older sibling, the Extreme Series, sits right alongside it.
2. Quad — four trumpets, big full sound.
3. Dual — the 2026 Dual shares the Boss design, and it's the one to pick if your battery brand isn't covered by the Boss Series yet.
Skip the 5-trumpet. The on-board compressor can't push enough air for all five trumpets, so it ends up thinner and higher-pitched than it should.
Do I need a drill — or does it come with one?
No drill needed — and none included.
Ships fully built and ready to use — nothing to assemble, no tools required.
The only thing you add is a battery — the same cordless-tool pack your drill already uses.
Snap it in, pull the trigger — and it roars in seconds.
Everything a real train horn should be
- 150 dB of real locomotive thunder from genuine metal trumpets — the deep freight-train tone, not a tinny electronic buzz.
- Wireless remote up to 2,000 ft — set off a blast from across the lot, the campsite or the driveway without leaving your seat.
- Runs on the drill battery you already own — fits Milwaukee®, DeWalt®, Makita® and Ryobi®. No compressor, no air tank, no cans to ever buy again.
- Pre-built and 100% grab-and-go — zero wiring, zero install. Clip in a battery, pull the trigger, and it roars in seconds.

It's been a blast so far.
After receiving my horn putting together with super simple. I took it to my buddy's 50th birthday and it got plenty of use. Looking forward to the more opportunities to use it. Highly recommend it!
Blasting Company
We are using them as advance warning for our Blasting operations. Very loud. Only draw back is the size they are big and have to haul with care. Love the remote option.
Attention Get'er!
I was skeptical when purchasing however after seeing the quality of the product I became reassured that I made a good choice. I installed battery and horns and WOW...these are for real! Very Impressive!!!!
LOUD AF
It took me 15 seconds to assemble. It sounds LOUD, like a semi truck and possibly louder!
Best present ever!
Sturdy and quality product. Very loud horn when fully charged.
Awesome!
Awesome sound, easy to use! If the need arises, I will certainly buy from BossHorn again!
I've been testing out the Milwaukee Premium Boss Horn for a few days now. It's awesome being able to use it with the remote. It's been entertaining to see neighborhood kids running around trying to figure out where the trumpeting noise is coming from.
Awesome Train Horn (Dewalt 2 horn model)
I am using this horn to encourage honking from the trucks and cars which drive by the Axe The Carbon Tax Camp Protest Rally on Hway 1 just west of the Canadian city where I live. It is loud and perfect for the job.
