As an original backer who ended up not getting his order, then was given the air nano without a refund of the difference in price I'm staying away from these guys for the foreseeable future. The Air nano doesn't work great. A lot of dropped connections (despite their claims) and sub-par sound quality, in contrast to all of their marketing around their sound quality.
Also support is non-existent. For the price I'd go with AirPods or the Samsung Gear IconX (what I eventually bought to replace my garbage ones from this company).
Received my Air earpods and was excited to use them. From the second I got them paired to my phone until today they have not worked as advertised. Luckily (I thought), I'd just reach out to customer support to get a new pair because these must have been one of "the few" pairs that are defective.
Apparently customer services doesn't exist yet. Indiegogo, facebook, twitter, or anywhere else you can find crazybaby there are numerous complaints of non-working devices and no response from the crazybaby support team.
Another failed Indiegogo hardware project. Another massive success in fundraising with massive failure in delivery of a working product.
