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

So apparently these ran as a part of some Kickstarter lauding the dual drivers for stellar audio. I will say the audio on these are decent at the price point, but that's about the only moderately good thing I can say about them.1. The battery life max for me has been about 2 hours, at best. The left bud pairs through the right earbud, so the right one drains faster and they both disconnect. I will say one workaround is to pair the left earbud separately after the right dies, getting you another hour or so while you pop the right back into the case to charge (this significantly helps the experience, but it's a workaround that shouldn't be necessary)2. If the earbud isn't manually turned off before being placed into charge, it will remain on, continue to drain, and won't begin recharging. This is crazy because the earbuds go face down into the case. There is no way whatsoever to listed while they charge, so why would they not shut off and begin charging when placed in the case?3. Sometimes the earbuds will randomly connect to my phone while in the case, either draining the battery life of the earbuds, case, or both.Going bluetooth is so nice compared to wired. I loved these for about a day until running into the issues with battery life, and not even being able to charge these easily. If they could just extend the battery life over 2 hours and make these easier to charge, I would definitely recommend, but from my experience so far I would look at other options in the $50-$80 price range.

Likes -Has a great EQ built in for different listeners, I tend to prefer the bass boosted EQ.Decent battery life (I've gotten around 3 hours.)Pairs when taken out of the case like an AirpodPackaging and case feel high quality, case is made of Metal and is cold to touch.Can also use one at a time for continuous listeningGreat sound quality, sounds like a low range IEM, the dual drivers make a noticeable difference and allow for very crisp highs without any compression by the lows.Earbuds are light in the ear and comfortable for hours of listeningNo noticeable delay when listening to videos----Dislikes - The sound pass through feature does not sound ideal.The commands are not as intuitive as they should be and changed based on how you are using the earbuds,always found myself setting off other commands accidentally like the call last number command.The low battery warning comes on too early in my opinion, seemed to come on with about 10-15 minutes of battery left and go off every minute.

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)

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.
