Both. It's made from bioplastic and wood. The wood is used on the back of the housing to create a natural resonance. It's a perfect combo for this headphone. https://www.recyclingtoday.com/article/thinksound-launches-biplastic-headphones/ -Aaron, president and founder of thinksound

I recommend 72 hours of burn-in for all earphones.  The fitting size also needs to be correct in order to get the proper seal for accurate low-end.   Thanks!   Aaron Fournier President/ceo/engineer thinksound and first harmonic

Sure am!   Thanks   Aaron Fournier President/ceo/engineer thinksound and first harmonic

Probably not as they were custom made for the on.  If you own the On1 and need pads please email us at hello@thinksound.com as there is a 2 year warranty.   Thanks Aaron Fournier President and ceo thinksound/first harmonic

I hear ya.  Mostly BAT drivers.  I like simple dynamic designs right now and stuff that isnt too flashy.  Im kind of old-fashioned but it may happen in the future.     -Aaron

the earpads do get softer with body heat.  Cable microphics also drop over time.   Thanks Aaron Fournier President/ceo/engineer thinksound

Lets move the On1 talk to here maybe?  http://www.head-fi.org/t/689288/new-supraaural-headphones-from-thinksound-on1/90   Aaron

Unfortunately it would work to do that either.  It wasn't an amazon promotion but rather an unadvertised deal that wasn't processed correctly by amazon software tech when the deal was created.  Don't worry, it will be okay in the future.   thanks Aaron

@gikigill I appreciate the review but keep in mind this was not a code that was something advertised or anything.  While we do have a storefront on amazon the codes must be approved by them and their system doesn't seem to be playing nicely to say the least.  If I cannot resolve the issue with...

I will contact Jude.   Thanks Aaron

If someone wants to leave this as a rain2 thread and create another then I am all for it.   thanks Aaron

I have been researching the dual dynamic but so far Its tough to keep in a small package with the wood thickness limitations that I am comfortable with.  I will certainly keep working on it though.     Aaron

Feel free to contact me directly and I will always answer your questions, comments or concerns but as for stuff that is done through a 3rd party site it can be hard for us to control.  I will do my best though and call them tomorrow.     Thanks Aaron ceo - thinksound

High end what?  Earbud, on-ear, over-ear?  I am always working on stuff and I have many different projects going.  I am working on an over-ear but I don't have really any info on it yet.  What would you like to see?   Thanks Aaron

Hello all.  I am writing to help clear some things up for you.  There was a promo on the rain2 and it seems many people found the code and took advantage of it and we think that is great.  I am aware that there was a code for the On1 and I actually saw it for myself but it didnt work for some...

The box it came it is meant to double as a case.  It may be cardboard but it is fine to use.

40%+ import tax in the UK.  I wish we could control it.   Aaron 

Did you return them to us at thinksound or somewhere else?  Something doesnt sound right about them.  Contact us through our support on our site and I will respond to you via email directly.   Thanks Aaron Fournier President/CEO/Engineer thinksound

    I just wanted to let you know if you bend the headband back it will loosen up a bit.  Dont be afraid to grab them and bend them back as the band has quite a bit of memory and it wont break.  Make sure you are putting the stress on the metal and not the plastic when bending.   Best...

I forgot to mention if your headphones are still within the warranty period we will replace them even if your dog ate them.  Its actually quite common.  Just contact us at hello@thinksound.com and we will take care of it.   Best regards,     Aaron Fournier President /CEO/Engineer...

I just wanted to let you know that we will be coming out with a new on-ear early this year.  I am working my hardest to not make it uncomfortable as that has always been my complaint as well.  So far we are very close and stereophile should have a sneak peek at it in the next week or so.  An...
