KNZ Technology KNZSNDFLXGRY Soundflux Dual-Driver Truly Wireless in-Ear Stereo Headphones (Gray)

Honestly i dont know how people think these are bad when they could last a whole day with a charge and the bass is crazy it needs to be a lil bit lowder but over a 5 really good i love them do not regret buying them

Initial impressions: Packaging is a nice experience. 4 stars. Sound quality is average (wife's airpods sound much better.) Soundflux is "flabby" in the bass compared to Airpods - Airpods have a crisp and tight bottom end. Soundflux is very "middley" so accentuates guitars, vocals. I actually find that the sound blance across the frequencies is way out. Trebles and bass are very subtle in comparison to mids. As a musician I would not rate these for sound quality. They actually sound like a cheaper pair of wired in-ear headphones. But I'll say all that to say these will suit me (albeit I feel like I overpayed for them) as I will use them for running (so hopefully they hold up their claim that they are sweat proof!) as I mostly listen to Audiobooks and Podcasts when I run, which is mostly spoken word, meaning I won't need all those vibrant and beautiful frequencies found in expensive headphones. (For clarity I purchased these via IndieGogo campaign which has been filled with controversy - and a lot of backers still don't have their headphones despite KNZ offering them here on Amazon)

I use this playlist for specific genres with specific voicings and instrumentation. It is a wide variety of music, testing dynamic ranges, equalizer ranges, and even volume levels: "Lingus" (Snarky Puppy) "Aha!" (Pentatonix) "Separate Ways" (Journey) "Wishing You Were Somehow Here Again" (Live at the Royal Albert Theatre) <i>Lobet den Herrn, alle Heiden BWV 230</I> (Tafelmusik) "God So Loved the World" (Mormon Tabernacle Choir) <i>The Rite of Spring,</i> "Part I: The Adoration of the Earth" (Lorin Maazel & the Cleveland Orchestra "Over the Horizon 2016 Samsung Galaxy" Dirty Loops "Mas Que Nada" (Sergio Mendes & Brasil 66) "What Is this Thing Called Love?" (Bill Evans Trio) "My Funny Valentine" (Carmen McRae) <i>Turandot:</i> "Nessun Dorma!" (Luciano Pavoratti with Zubin Mehta and the London Philharmonic Orchestra)

Same brought on indigogo and they are nothing like quoted and now they have every ones money you don't hear from them. Soundpass doesn't work,supposed to have acc codec , that doesn't work, supposed to have 4 hours battery but max is 2hours and 20 mins. If they actually update the firmware with what was promised i will change my review otherwise dont buy.

Received mine with a clicking sound on one earbuds. KNZ does not respond to emails at all so I'm left with a faulty earbuds. Bad support. Bad quality!
