KB02

I have these and listening to just speaking the bone conduction driver has a twanging sound that drives me insane, and not in a good way. For music, they are fantastic for the price and the shells are... Sexy 😂 Your mileage may vary with the bone conduction technology

I don't think it is tbh, in my experience. Just podcasts and heavy speaking shows/movies for me has this resonance that felt anxiety inducing.

I've only heard one, which is the KBear KB02. It's the cheapest, but from what I've heard, most of them with the same driver type sound pretty similar. It's shit. Kind of a gimmick that doesn't work well and messes up the tuning of the IEM. The other type is a PZT driver, not true bone conduction. Apparently some of the higher end ones are better, but OTOH it's unclear if the bone conduction is actually doing anything, because it's turned down so low to avoid the negatives. I'd give them a year or two to see if the technology matures or just dies off like 3DTV. With IEMs, if it has good sub-bass extension you *will* hear it, unlike most headphones. You won't feel it in your body though and even if BCDs get good, they're still more hearing than feeling as they're only affecting the bones near your ear canal.

Aye a fellow IEM enjoyer. Glad the kb02 is working for you they have great sound stage, but I found them very bright and sibilant for my preference.

I prefer the Kunten over the kb02, its better turned and has better soundstage and imaging. Sibilant game effect such as Arthur's pistol in RDR2 and the service pistol in Control make me wince out of discomfort when shot cause the treble region isn't tuned well and peaky for my ears.

They dont have to be kz either just as long as the pins match you can use any brand of iem you want. Cause ive got one set hooked to a set of kz zax iems and one set hooked to a pair of kbear kb02.

This seems to be the problem with every bone conduction thing in an iem ive run into their all centered at about 100 hz. Not much on either side of that either. I feel like for most music and to get the like subwoofer in your head feel the center frequency needs to be lower than that and/or alot wider than 95 to 105 hz.

My kb02s hit the same 100hz plus or minus about 5 hz useing a tone generator website. 70 hz i would say would be better for music altho probly less fun for games. Which is what i use my kb02s for mostly. If these vibe-x arnt too expensive ill buy a set just for fun cause i enjoyed the kb02s alot and use them often.

It is for the kb02 but its only like that when you use the sine sweep to target the exact frequency it moves most at and turn the volume way up. Its not near as strong as that during normal use and its not a rattle its a vibration like you would hear if nothing but a subwoofer was playing a single note at 100 hz and its still pretty strong around 5hz either direction of the 100. So from 95 to 105 much farther off from that it drops off pretty fast. Its still there just not as strong as you leave that range and i honestly cant remember where it is it seems to not be doing anything at all.

I have both closed back headphones and iems and for gameing I like the iems better but that definitely seems to a minority opinion. Ive got a set of the kbear kb02s that I really enjoy for gameing along with quite a few others but I come back to the kb02s even over higher priced sets and sets that I think sound better for music than they do. So id recommend at least trying a set for gameing and music you may find you like them.

Ok so I chased the same bone conduction hype when I was getting in to IEMs.... The problem is, the better implementation, the less obvious it's actually doing anything at all. Kb02 vibrates at high volume, which is fun and obvious. But it HAS TO be high volume. BGVP DMA- The cheapest way to get the "proper" Sonion bc drivers, so I was expecting a lot. But I couldn't tell you what it's bone conduction is actually doing. I have no idea if it's even connected. The IEM sounds great, but if that's because of or in spite of the BC driver, I don't know. Bone conduction is voodoo.

Bone conduction is VOODOO that sometimes does nothing and sometimes does everything. Mini reviews- 1) Kb02 Most days- "This sounds pretty bad, and I hear no bone conduction". Random days "WTF why do I hear bone conduction really strong with Oasis, this is fun" 2) Kiwi Ears Etude - "This actually has really strong vibration, it's so fun... But... Why is it doing it only on snare drums and not the bass?" 3) Apevoix Grit - A great IEM, but the BC is usually fairly mild, but occasionally, wild. 4) Penon Fan 3s - "Why can I feel and hear it vibrate really strongly in my hand, but it changes nothing to the sound?" (I returned this one- it just wasn't very good. But may have been broken) 5) Bqeyz Wind- Didn't get very long with these but no obvious BC to me. 6) BGVP DMA- "Everything else used cheap BC. I bet if I buy one with Sonion BC, it will be great!" It was not great. It's a really great IEM, but it has the LEAST obvious bone conduction effect. 7) QoA Martini - Borrowed it... I loooove this IEM. BC is good, and always noticeable, huuuuuge soundstage and seperation.
