Question: Will these work in our 2007 Toyota Sienna?
Document: Fantastic!Works in my 2010 Toyota Sienna and very happy with the performance
I needed new headphones for my Toyota Sienna. These are great my grandson loves them! All we did was install batteries and turn them on. We love the fact that they fold up. The ones that came with the car do not fold. These are very easy to use and store. I purchased 2 sets. At this time I have been using them for over a month everday and we have had no issues with them.
They work with my 08 Sienna. Volume isn't  great but works if there  is not to much back ground noise. Bought 4 of them one kept cutting in and out. Not bad for the price. Kids seemed to enjoy watching the movie and they were quiet.
On initial review I like these headphone very much. They worked right away with my aftermarket DVD player installed on my Toyota 4-runner. They are small enough, though adjustable, to fit my kids heads without falling off like most headphones. Padding is nice and soft. I love that they fold compactly for storage. I do hope they will last.The shipping was faster than i expected.
Would not work with my DVD players
They work perfectly in our Cadillac SRX and a great price!
these do not work in my 2012 suburban. inoperable and won't even switch channels. do not buy these head phones.
They work great. The kids love them. The kids say that the sound is great in them. The kids want me to buy more.
The volume is very low. It took several days for the headset to work. Would not recommend this product to anyone.
WE purchased these for our Honda Odysey 2012 van. We loaded the batteries and starting using them. They work great!
Answer: if your Sienna have a remote these will work the uses the IR just like your remote you only have to put batteries in them and select between A or B on the side of the headset they do not have a overall loud volume but they will be great if you're using them for children
