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.

This is the best accessory you could get for E biking. I did get them at a lower price, but I would spend the full price on these. It just makes it so much more enjoyable to talk to your companion while you’re biking without having to holler, can’t recommend the Sena pi enough money well spentAlso, they fit any helmet so if you’re biking with someone that is not with you all the time you can always take them off the helmets and put them on a different one. It’s just so smart.

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

Desde el primer día de uso ves como cambian por completo las salidas en bici en pareja. La facilidad de comunicación es algo a lo que ya no querrás renunciar, el sonido es muy claro y sin fallos. Los tengo desde hace varios meses, pero tenían un problema que no te dejaba disfrutar del todo de ellos y era la duración de la batería que estaba muy lejos de lo indicado por el fabricante ya que a duras penas llegaba a las dos horas y media. Esto obligaba a llevar una power bank para recargar en alguna parada. Con la actualización de firmware a la versión 1.02 ha cambiado por completo y se alcanzan las seis horas indicadas por el fabricante. Ahora son realmente útiles.El alcance indicado de 400 metros tampoco es cierto yo diría que se queda en unos 200 metros que son mas que suficientes. Esta distancia se consigue mientras haya visión entre los dos ciclistas, en el momento que se vuelve una esquina o hay arboles por en medio la conexión se pierde a una distancia muy corta.Para mi otro pequeño inconveniente es que si lo llevo ademas conectado a mi teléfono (Iphone) la comunicación con el otro se entrecorta a veces, pero como digo solo ocurre si lo tengo conectado al teléfono, así que lo descontó y listo, asi la comunicación es perfecta. El otro dispositivo va conectado a un teléfono android y no da ese problema.A pesar de este par de detalles para mi, es mas que recomendable, es imprescindible ya que cambia por completo nuestras salidas en bici, permitiendo una comunicación perfecta en todo momento.Esta actualización ha sido increíble como ha cambiado, siendo el mismo producto..
