The Sena 50S is worth the money if you ride with a group that already trusts Sena, and it’s one of the best-sounding motorcycle headsets you can buy at any price. It’s also the unit most reviews stop describing the moment the box is opened, before anyone digs into the settings menu or rides it through a storm.
This review picks up where the glowing first impressions leave off: the setup step that’s turned off by default and barely explained, the waterproof rating Sena never published, and the real difference between the 50S and its cheaper sibling, the 50R.
If you’re still weighing this against the wider field, our complete buyer’s guide to motorcycle Bluetooth communication systems covers where the 50S fits next to Cardo’s lineup.
What You Get and What It Costs
The 50S ships as a single unit or a two-rider dual kit, and either way you get the same core hardware: a jog-dial control module, Harman Kardon speakers and microphone, a universal clamp mount, and a WiFi charging cable that pulls down firmware updates on its own.
Pair it with a solid phone mount and the 50S also handles turn-by-turn directions through whatever navigation app you already use.
Key Features
- Harman Kardon Audio: Premium high-speed sound clarity
- Auto Wi-Fi Updates: Smart cable downloads firmware automatically
- Glove-Friendly Jog Dial: Raised tactile dial for easy navigation
- Dual Audio Jacks: Includes 3.5mm earbud and AUX ports
Where the 50S Earns Its Price
Owners upgrading from an older Sena unit, the 20S or the 30K, describe the same thing over and over: the sound jumps first.
The Harman Kardon speakers push more detail at highway speed than Sena’s older hardware ever did, and several long-time Sena riders call it reason enough to upgrade on its own, before Mesh 2.0 even enters the conversation.
Mesh range holds up too, with a catch. Sena rates the 50S at 1.2 miles rider to rider in open terrain, and riders who’ve tested it on hilly, tree-lined roads report closer to half a mile before the network starts working harder to hold the connection.
That’s normal. Every manufacturer’s range number comes from open, flat ground, and the network doesn’t drop the call outright; it reroutes through other riders in the group.
The people reporting this shorter range still call the connection clean and unbroken, just shorter than the spec sheet promises.
The Setup Step Most Reviews Skip
Here’s something almost no review mentions: Audio Multitasking, the feature that lets you run music, GPS directions, and an intercom conversation at once, ships turned off.
Sena’s manual buries the fix in section 13.2.8, and even that note confused enough owners that Sena’s support community had to walk through it step by step: turn the feature on in the app, then power the headset fully off and back on before it takes hold.
Skip that restart and the setting won’t stick, and your music will keep cutting out the moment you connect to another rider.
Once it’s set up, riders report it works as advertised. The problem sits entirely in the onboarding, not the hardware, which is exactly why it’s easy to miss in a review that never gets past the unboxing.
The Waterproofing Gap Nobody Advertises
Cardo publishes an IP67 rating for its comparable PACKTALK EDGE, meaning the unit survives full submersion for a set time. Sena has never published an equivalent number for the 50S.
That doesn’t mean it fails in the rain; plenty of owners ride through storms without a single issue. But it does mean you’re trusting a general claim instead of a test result you can compare against a competitor.
If you ride in the rain often enough for this to matter, our guide to riding safely in wet weather covers what else changes about the ride itself, not just the gear.
Pair It With Earplugs, Don’t Replace Them
Better speakers don’t cancel wind and engine noise, they just make it easier to hear over it, which can tempt riders to skip earplugs since the 50S already sounds clear on its own. Don’t skip them.
CDC research on noise-induced hearing loss puts the damage threshold at 85 decibels over sustained exposure, and highway wind noise alone regularly crosses that line before your engine adds anything to it. Good speakers change how well you hear your ride, not how much damage the ride does to your ears.
If you’re not already running plugs under your helmet, our guide to motorcycle earplugs covers options that still let intercom audio through clearly.
50S or 50R? Settle This Before You Buy
The 50S and the 50R share the same Mesh 2.0 network and nearly the same audio hardware, and buyers mix them up more often than you’d expect. The real differences come down to how you’ll use the thing:
- Control: the 50S uses a raised jog dial, easy to find with thick gloves on. The 50R uses three low-profile buttons instead.
- Mount: the 50S clips into a separate base, so swapping it between two helmets means buying a second base. The 50R sits flatter against the helmet with hook-and-loop or adhesive mounting, built to stay put rather than move around.
- Extras: the 50S includes an AUX port for a wired MP3 player and a 3.5mm jack for your own earbuds. The 50R has neither built in.
- Battery: the 50S edges it out by about an hour of talk time.
If you want the physical dial and don’t mind a slightly larger unit, get the 50S. If you want the lowest profile on the helmet and don’t need the extra ports, the 50R saves you a little money for nearly the same core experience.
What Long-Term Owners Report
Most complaints about the 50S show up in the first few weeks, tied to setup. A smaller number surface after months of use, and they’re worth knowing even though they don’t affect every owner.
A handful of riders have reported the voice command system suddenly failing to recognize commands after a firmware update, something that cleared up for some after a factory reset but isn’t something Sena offers an official rollback for.
Separately, at least one long-term owner reported a battery losing capacity around the one-year mark and a slow response from Sena’s warranty team.
Neither issue shows up often enough to call it a pattern, but a unit this dependent on software is only as reliable as its last update, so it’s fair to expect the occasional firmware hiccup rather than zero surprises for three years straight.
Who Should Buy the Sena 50S
Buy it if you already ride with a group on Sena mesh, or you’re upgrading from an older Sena unit and want the sound jump without switching brands. It’s also the stronger pick if call and music clarity matter more to you than outright mesh range or a guaranteed IP waterproof rating.
Skip it if your riding group already runs Cardo mesh, since the two won’t talk to each other in full mesh mode; read the Cardo vs Sena comparison before you commit either way.
Skip it too if you’re not sure a communication system solves a real problem for you in the first place; our guide on whether you need one is worth five minutes before you spend over $300 to find out.
And if that amount of money is more than you want to spend regardless, our budget motorcycle intercom picks cover the field under $100.

FAQs
How do you turn on Audio Multitasking on the Sena 50S?
Open the Sena app, enable Audio Multitasking in the settings, then power the headset off and back on. The setting won’t activate until after that restart, a step the manual doesn’t make clear.
Is the Sena 50S worth it over the older 30K?
Yes, mainly for the sound. Owners who’ve made the jump call the Harman Kardon speakers a real step up, and Mesh 2.0 is now available on the 30K too through a firmware update, so sound quality is the main thing you’re paying extra for.
