TIN HIFI T4 alternatives

Good price, but the connectivity is so bad, suddenly my left earpiece just dont want to connect anymore, even though Ive followed all the guidelines. The headset is insanely bad, to speak with another person via phone is just not possible. They dont hear you! Of course this Hyphen2 was sold via indiegogo or Kickstarter, its like a modern "TV-Shop" its sold there because it cannot be sold anywhere else.. Dont buy these headphones, buy something proper instead that has proper reviews. Do not recommend these ones!
