Passive noise canceling?!? Another vote here for willful, deceptive description. For everyone else using the term noise canceling means activate circuitry not just the fact these are in ear devices that provide some sound isolation. I'll pass on this drop.

bsoplingerIt's an industry phrase. No, it's not active noise cancellation. It does effectively cancel about 27 dbs or more of outside noise.

bsoplingerWe don't need to provide a deceptive info. A passive noise cancellation is a well-known fact:

TREBLABThe article describes it more like an ear plug then an active phase cancelation circuit.. That would probably affect the water resistance since the mic needs to be exposed to be accurate enough to actively cancel the noise. Not to mention the cost would be a lot higher if it did contain a seperate active circuit capable of effectively cancelling or amplyfying outside noise... I'm speculating a little not knowing what's currently available on the market but at that price point the components would have to be dirt cheep and probably make the product sound bad.. I wouldn't even consider getting into the active thing anyway. Working full time in the production world its universally accepted that passive is better because it's simpler, rugged, uses higher quality components and less likely to add unwanted artifacts like feedback or handling noise.
These ear buds would be the equivalent of a sealed closed back designed headphones that are used by studio musicians, drummers, and DJs who need to reduce the noise as much as possible and I guess that would be the equivalent of working out or traveling where the environment is a distraction. That's the intended market segment right?
From my perspective headphones are used daily for hours at a time for mixing and recording, -27db is a significant drop that would require a sealed ear piece that Teblab advertises as passive noise cancellation. Lets be honest and just call it hearing protection instead.
Thats perfectly fine for tuning out the world but that limits the products usefulness and would keep me looking for a smaller quality bluetooth earbuds so I can untether from the studio while evaluating mixes..
I prefer a semi open AKG type headphone design that lets in some ambient natural sound to blend with the monitors and stay alert enough to hear what's going on. Sealed closed back designs are definitely useful but for day to day a -12db - 6db reduction is comfortable for regular home use.
The ideal Bluetooth earbuds for me would have a -27db sealed ear piece acting as ear protection for live sound along with a less dense -12db and -6db option.. Thats something I'd consider for under $100.00. If they sound accurate like my AKG's or Sony's then we might have a winning product that I haven't yet found.
