Sena SPH10S


Pros: Clear sound quality

Cons: Controls are not intuitive(to me)

Helmet installed into: Giro Seam

I've been using the Sena SPH10S for a couple months to try all features in different conditions.  


Set up:

Installation and pairing was easy which is a big plus for those who aren't as tech savvy and want the convenience of a blue tooth head set. 



During initial use, the pairing kept dropping signal, which was frustrating, but uninstalling and reinstalling seemed to fix the issue.  After getting the pairing issues sorted out, I made a few calls and used the iPod on my phone and was quickly impressed with the clarity both from the iPod and from the phone conversation.  Philpug used the second Sena to talk on the phone to test the microphone/phone clarity.  I was surprised at the quality of sound from his microphone even while in strong winds.   Big thumbs up for the microphone!


Next up, we tried the intercom feature:

The intercom is handy and does an auto search when out of range, to find the other "paired" user when he/she is in range, which is a great feature, as long as you don't run the battery down trying to search for the other user.  The range is pretty good(not sure of the distance) as long as you're in line of sight which is pretty handy when doing video for ski clinics, which is something that we do quite often. 


If I had one complaint about this particular model it would be the knobs and buttons, as they are not intuitive to use.  

With three buttons and one dial, I had to think about which one to use for the task I was trying to access. 


All in all, this is a great bluetooth for day to day use, and I'd highly recommend it for someone looking for bluetooth convenience in their snowsports helmet. 




Pros: Well designed, good ergnomics, best solution I have found for skiing communications

Cons: occasional phone pairing issues w/Andriod if phone has automatic lock (enterprise email)

Here's my review of the Sena SPH10G (Giro version) bluetooth headsets (2 units purchased directly from Sena) which I got late January and have been testing ~4 weekends skiing crystal mt in varying weather conditions including some low-temp days in the teens, plus some rainy wet days.


Repost of review linked to the Bluetooth Shootout thread.


Bottom line: B+ rating which would be A if the occasional lost pairing issue was resolved, and button placement re-arranged to address ergonomics using gloves.



  • Got the Giro version which fit my G9 and wife's G10 helmets perfectly.  Simply pull out the old flaps and insert the new ones. Great design.
  • Paired my unit with new Motorola Razr 4G-LTE andriod phone that is also configured with corporate enterprise email -- caused lost pairing problems, mostly resolved, more below.  Razr running Andriod 2.3.6, system version 6.12.173.XT912.Verizon.en.US, not rooted.
  • Paired wife's with older Motorola VU-204, no problems
  • Used Razr paired unit for bluetooth music, intercom and phone
  • Used wife's VU-204 paired unit for phone and intercom, did not try music



  • Had problems with my unit loosing pairing which I attribute to my corporate enterprise email automatic lock feature.  Problems were mostly fixed by configuring the andriod "location & security -> Allow bluetooth bypass" setting.  My unit continues to loose connection to the phone (for both calls and music) about 2-4 times a day during periods of inactivity (no music or calls) which is fixed by hitting the Razr multi-function unlock button.  Unclear if its a Sena firmware issue or andriod OS since the same issue was mentioned in one of the andriod forums involving bluetooth headsets.  I decided to keep the units since the work-around is easy and only required if I turn off the music and keep the unit idle for extended periods.  If music is kept on everything is fine.
  • Worked w/Sena support troubleshooting issues and exchanged the original 2 units with replacements.  Support was excellent, and Sena agreed to extend my return window to give me extra time to troubleshoot.  Sena agreed to look into the firmware issue and fix it with a firmware update (supported via web app) if it turns out to be on their end.
  • If your phone is configured with corporate enterprise email, you might have problems depending on the phone & OS.  No data on iPhones having this config.
  • Music quality is good though bass is lacking compared to previous $15 skullcandy wired giro tuneups which were better.
  • Tried my Creative Zen Nano mp3 player wired connection which worked, but volume was lacking even at max nano output. Tbd if issue is the nano player output voltage or the unit.  Mp3 not important for my usage.
  • Buttons and controls very good with gloves once you figure out how to not press both (lhs) buttons simultaneously and turn off the units.  Wife still has issues with this.  Suggested to Sena that they relocate the phone button to the rhs ear flap jog dial location which would allow optimal ergonmics by simply using an open palm glove to initiate calls, intercom, or music.
  • Button-initiated Phone call voice activation and single-button call answer great.  Like the separate volume control for phone vs music vs intercom.
  • Music initiation and controls work great.
  • Intercom initiation and sound quality good but sync delay of 5+ seconds a bit annoying
  • Intercom range seems to be around 600-900' max line of sight, open terrain.  Limited testing in trees though ok for not-dense trees up to perhaps 200'.  When my tree ski buddy gets a unit we will give them the real test.
  • Units are compatible with an optional Sena gmrs radios bluetooth adapter (~$170) which is pricy, but would address the intercom range issue.  Cell phone reception very good at Crystal so I'm retiring the gmrs radios.
  • Battery life excellent... no issues loosing charge running music periodically all day (6hrs) while making occasional calls and using intercom.



I tried making cheaper solutions work over the past 4 years but gave up (2012 Giro $80 bluetooth links ... didn' work at all with my phone, skullcandy 2-way gmrs radio links worked ok ~2yrs but crappy materials/cabling broke multiple times, and ebay kawamall midland and skullcandy knock-offs lasted 6 weeks before failing, some units doa).  Finally looked into motorcycle solutions and found these which I think are the best of the bunch for the skiing application.  Craftsmanship is top-notch and controls very simple to use.  Would have been an A review if not for the lost paring issue and wife's issues working the button controls with gloves.  Hope to somehow migrate these units into my mtn bike helmet for the off-season, and would like to get a waterproof version for windsurfing.



Pros: Great controls

Cons: Frankenstein knobs

Overview: I had a chance to spend a couple of days with the Sena SPH10s snow specific bluetooth headphones. The SPH10s system comes complete with helmet ear pads and fits very will and comfortable,it is designed to work with Giro, Red and Smith helmets. 


Use: The installation, pairing and charging is very easy and simple. I do like the ease and size of the buttons. I have used a few bluetooth headsets and the SPH is by far the easiest and most intuitive to use with and without gloves. The SPH10s can also be set up wired along with Bluetooth. 


Performance: I haven't tried the unit with any other devices other than my iPhone 4 but they say it work with any bluetooth items including GPSs..I don't know why you would be using this with a GPS but if you do, this will work. Working with the iPhone was very simple and clear what works exceptionally well is the "Voice Control" integrated in the iPhone., all you have to do is hit the button and say "Call [recipients name here]", if the person has work/home/mobile numbers, it will ask which one. While this is a Apple feature, the Sena works seamlessly with it. Sound quality is superb both through the speakers and the sound quality into the integrated microphone, per the recipient, sound quality is on par with just taking into the phone directly and will no wind noise at speeds well over 25 MPH. I have yet to try the intercom feature with allows you to commentate with another user at up 1,000 yards, I am sure there are limitations with line of site and varied terrain but it will be interesting to find the limits. 


Overall: The SPH10s is a top notch unit and if you are looking for a bluetooth, make sure you put these on your list and should be either at the top OR your top choice...especially if you have an iPhone. The only negative I could come up with is while the control dial is on the left side, they put a cosmetic dial on the right it does give an unnecessary Frankenstein neck bolt appearance..a small negative in the world of FUNCTION over FORM. 



Review Addendum: 


INTERCOM: We had a chance to play with the intercom feature of the Sena. I will say it worked very well but with a limited range, The limitations were about 300 yards with either line of sight or partial line. In reality I am not sure if the expectations should be anything more, these are just headphones. In using the intercom, the sound was very clear and if communication was lost it would go back to the music that was playing then if the other recipient came back into range it would pick up. When would you use this? That is a question that TC and I bounced off of each other..while using the communicators...instruction...video, be it fun or MA, photography, setting up shots or even just talking amongst yourself. While I am not sure I would be the Sena's FOR the intercom, but it is a feature we might use for time to time.
