Firefly alternatives

Rolling Square-Hyphen customer service sucks. I've purchased Hyphen 1 and it was a total disaster. Pairing the earbuds was always a nightmare and after a very low use at home, the left earbud just simply stopped work after months of use. They told me that it was a "fabricating issue" and they never got responsibility for this. They just gave me a 20% of disccount in the Hyphen 2. So this is their business model, make bad products to make you buy the "new ones" in a year with "discount". In the emails they told me that there were not left earbuds available to replace mine, but they send me a url to BUY a left earbud. So there was available to sell but not to take care of their "fabricating issues". I won't recommend to anyone to buy this, there are a lot of other brands with better business practices.
