pi, Universal Bluetooth Intercom Headset, Fits Most Cycling and Multi-Sport Helmets

I bought these for me and my wife while we are out cycling and they are absolutely superb - a total game changer for us and make going out for a ride a LOT more enjoyable by removing the frustration of trying to communicate while we're riding. They are full duplex and communication is open all of the time so there's no vox delay and it's just like talking on the phone. They fit onto your helmet straps and are not intrusive and don't block you hearing other stuff around you. Be aware though that these ones only connect between two units - not more than that. I've not used these for phone calls or music but they do that as well. They don't seem to be affected much by wind noise - certainly going downhill fairly fast doesn't stop them working perfectly well. They have a range of around 200 meters realistically which is plenty for what we require. If you go out of range then they do reconnect automatically when you get back in range. The volume is perfectly adequate and even though I'm a little hard of hearing, I don't have them turned up anywhere near full. They charge with a USB C charger and if there was any criticism I could add it would only be that the microphone protection metal mesh gets squished a bit after a few uses but it has no functional effect and you can't see it.

Bought two - fitted them to my and my son’s helmets. Was awkward on his Specialized helmet due to the placement of the straps but still managed to install it without conflicting with sunglasses- which are always a necessity while riding due to bugs etc. Pairing with phone and with each other very easy if you follow instructions. Paired both with Sena apps too on IPhones to check for firmware upgrade. Sound quality acceptable (not great) but wind noise requires you to run them at a fairly high volume. They appear to keep sound on continuously even when nobody is speaking - wonder about battery life but we have been ok for up to 3 hour rides. Intercom drops if you do not maintain line of sight with each other. Happy with them and they help us ride together and chat while doing so - and safely. Used to have Cardo/Terrano BK-1 units which failed so can compare.

These are just brilliant. Wanted something like my Cardo system I had for motorbike . Wasn’t sure I could get anything for cycling . Saw slot of a lot of options for smart helmets but wasn’t sure what would best suit me and my needs . Watched loads of utubes and reviews galore before deciding to buy a couple of senna pi pieces. Not cheap so I had to be sure . And these are great . I can swap them from helmet to helmet which was th e biggest drawback with smart helmets. I am able to select who I ride with by giving them a pair for the journey ( hubby/ daughter/ friend) the sound is great . Hear each other perfectly as though we are having conversation next to each other. Wire is tucked away easily in helmet , no complicated wires to install each time . Range is perfect, if your cycling together you never more than a mile apart. Came in perfect for safety. On a night ride out I lost my main light on the road which was then ran over by a car so I was riding depending a lot on hubby bike light for guidance or motorists with headlights . Even I though I went on foot paths to stay safe it was super scary - pitch black . We were easily able to communicate when I couldn’t see end of path. Hubby was able to stay close and keep me safe. If it wasn’t for these Sena pi’s , hubby would have riden off not knowing what had happened and I would have freaked out being on my own in total darkness . Fantastic buy

In recent years my wife and I have become keen tandemists (is that a word?).now the thing with husband and wife tandemists is that they either both love it or it’s grounds for divorce. There is not a lot of middle ground! And the biggest problem that arises is communication. It is essential on a tandem that both the pilot, the one at the front, and the stoker, the one with the view of the one in front, are most definitely on the same page when navigating through the busy roads of today. If one stops pedalling for instance, it can lead to the other being launched skywards when the expected pedal does not go downwards. Also if one decides to wave in a friendly manner at the passer by shouting ‘she’s not pedalling in the back’. This is an unwritten rule when ever you see a tandem by the way. It causes we tandemists no end of laughter at this witty repose every hundred yards on our quiet day out. Where was I? Oh yes, communication. We purchased a set of the subject Sena Pi headsets on the recommendation of a fellow tandemists and we have not been disappointed. The speech is clear and distinct and the wind reduction works well. They work well over a considerable distance as well, very useful when the pilot, ie me, is sent in for ice cream while the boss guards the machine outside. It causes much amusement to those around as I mumble through all the available options, apparently talking to myself but does save me from the ignominious failure of buying the incorrect flavour for how my lady is feeling on the day in question. The headphones are very light, neat and unobtrusive and fit on the helmet straps. On the occasions we have cycled rather than ridden the tandem the range has proved more than adequate for clear communication.

Avoid this and other SENA headsets - I had an SPH10-10 that failed too. The firmware updates and support from SENA are terrible. SENA help via email is in German - they do say if you are writing in English they will reply as soon as they can. 2 weeks later a reply but fobbing me off to Amazon who couldnt replace the SPH10-10 even though it was within warranty. I now have very expensive earplugs. I did get a refund for this PI, but the whole experience with trying to get quick support from SENA has been very frustrating. By the way, it is not seamless connecting the PI to the SPH10-10 - even when they were working. Just because they are SENA doesn't mean they easily recognize each other. Buyer beware.

Funciona perfectamente, se escuchan bien y se conectan bien uno con otro

Solved the windnoise problem. Installed Devine WS20 broadcast-microfoon windkap (windscreen)( bax-shop.nl €1.24 ). Windscreen fits perfectly, only needed to shorten it by approx. 5 mm and make an incision for the helmet strap.Easy install; takes about 5 minutes.tested it on our E-bikes during 23 knots of wind; no windnoise anymore ! Windscreen should be included with Sena pi set.

Acquistato con un po' di paura pensando ad una funzionalità scarsa , invece promosso a pieni voti ,installazione sul casco molto facile,app molto semplice ed intuitiva , connessione ad un altro interfono sena facilissima audio molto fedele e ad un buon volume, range ottimo non si scollega mai anche a distanza di 30 metri e coperti da oggetti la comunicazione è stabile!!!! Sopra i 30 km/h si inizia a sentire il fruscio del vento per il momento provato solo in comunicazione in coppia . PROMOSSO A PIENI VOTI

Ce casque Sena pi est vraiment le produit dont j'avais besoin pour communiquer en vélo, en plus il s'adapte très bien au casque et fonctionne merveilleusement bien.

Se ajusta a la perfeccion a mi casco Bontrager, buena calidad de audio y puedo hablar con mi compañera de rodada a cientos de metros.
