Why do these headphones need 2 lithium ion batteries?

Think that is just a typo in the listing. No batteries came with either of our sets, and no batteries needed. Have them here in my hands now...

I have requested amazon to update the page so now it does not say 2 lithium ion batteries are needed.

I believe the batteries will be in the ear piece. In the pair (of another brand) I have at home, if you pop the foam earpiece off, there is a battery inside each one.

Thanks for your question. These amazing sounding headphones have no active electronics and require no batteries. World Wide Stereo is 35 years old and and a very proud NAD dealer.

No, you need the rechargeable batter installed for the headphones to work. I charge mine after every trip (after it went dead once on me). For this reason, I prefer the previous version (I have both) that uses a AAA battery .. that you can get at any airport.

They are two Lithium Ion batteries, quite small and lightweight but hold a charge through a lot of work. So far I'm impressed.

There are no batteries in this headphone, only earplugs and a jack that plugs into the device that you're using.

You cannot replace this battery, at least without some electronics trickery. I have purchased three of these headphones and used the first two heavily for three years. They finally started falling apart and the battery life started getting bad, but I would estimate I wore each unit 3,000-4,000 hours before they wore out. I highly recommend them. Some might feel discomfort at first (due to pressure) but they conform to the shape of your head after a while.

They are high powered cochlear implant batteries....thy incidentally also can power the nano bugs! :)

They are small hearing aid type batteries. They come with the unit, and I have not had to replace them in the 2 yrs I have used the item.

Battery is for the bass subwoofer. (My personal favorite aspect of this product.) Absolutely worth every penny! Quality and performance are superior to other skull candy models in my experience. I highly recommend purchasing them especially if you like an extra bass kick in your music.

The battery is included and built into the device. It comes with a charging cable- you don't need anything other than what's in the package to use the headphones.

Batteries will last 20 to 40 hours depending on factors such as quality of batteries and if headphones are being used to save power.

Best to open the battery compartment to see what battery or batteries are in there. This battery is very unique to older model headphones. The newer models have been engineered with standard rechargeable batteries...either AA or AAA. Here is a link to the manual for your headphones. Looks like they take aaa nihmi rechagreables. http://en-us.sennheiser.com/downloads/b7fb26ac9db2250b1da26812db05b5d9.pdf

What my search found was that there are indeed Lithium batteries. I usually will get two full days of listening wirelessly for about 7-8 hours a day.This is where i found out about the battery. http://mobile.pcmag.com/?origref=https%3A%2F%2Fwww.google.com%2F#!/article/52c33014ec069126190966c2-beats-by-dr-dre-studio

I have two Able Planet headphones, the foldable one and another that is over the ear and not foldable. Both only have one AAA battery. Are you sure your headphones have two batteries?

The battery does not come with a charger. You have to charge it in the headphones.

My Sennheiser headset needs only one charged up battery at a time. I normally have one being charged up while the other is being used in the headset itself. The Sennheiser B151 rechargeable batteries are excellent.

There are two kinds of batteries available for that model. The Nickel Cadmium and the Lithium Ion. The Lithium Ion lasts a lot longer. Also as to what i understand, that comes with a rechargeable type. You might want to get these instead. Also, as i have consulted some Otolaryngologist (ear Specialists) these sound amplifiers act as a poor substitute for hearing aids. But i guess you know by now that real hearing aids are costly. That is probably why you got this unit, as i did myself. But for me it served my purpose.
