Theheadphonelist made a review for Aiva
"For a company I’d never heard of, SendyAudio crafted an exquisite headphone. Aiva Black Beauty Series is a triumph of performance, design, and comfort. When detail and resolution are at the core of your need, and nothing makes you quite so happy as oodles of treble sparkle, Aiva should be on your short list. This sort of tuning can go terribly wrong. It’s a testament to SendyAudio’s skill that they created something so pleasurable. I can’t wait to see what they come up with next."
