Sorry search is down atm, and I can't find what I'm looking for by browsing 426 pages of this thread :wink: I'm running into a problem connecting to the ES100 on iOS14. The manual said that there are two modes of connecting via Bluetooth "Ear Studio Connected (i)" <------- Regular...

I love this new generation of bluetooth dac and their apps, and don't want to switch back. But the ES100's built-in amp is not really able to drive some of my less efficient full size headphones. Anyone else has this issue? Does anyone use a good ol' analog portable amp to pair with the ES100...

Any update on how you like it? I just got my Chinese buds and am trying them now. I've dropped my left one 3 times so far when taking off a jacket (it's pretty loose), and I really need a workable solution before I lose it for good.

I love my APP with one exception: They aren't super secure, particularly if I'm chewing it works itself loose way too easily. But I've also had one fall out while boarding on the jetway, could have been bad. So I read on this thread about the effect of the foam mod w.r.t. the NC mic, and was...

Swore off buying more headphones last year but the bug has bitten back in a big way. However, I want to do it in a more wallet friendly way. So here’s where I’d love to get your help: I want to get a few (3+) ChiFi IEM/ earbuds that run the gamut in terms of sound signature, drivers/armatures...

This may be the single worst user interface I've ever seen. Even after your helpful instruction it took me awhile to figure out to hit the tiny [next] button to advance each step :-) Having said that, are their cables any better than their web page? Anyone received cables from them?

FYI, back on sale at Amazon again for $60

Can you tell me which version this is? Pro? 32 ohm? 250 ohm? Thanks! Sent from my iPhone using Tapatalk

Sorry for the noobish question, but my first Head-Fi quality phones were SR-80i years ago and liked the sound very much, but in the process of "upgrading" I sold it and have regretted it ever since.  I've also had an HF-1 which I failed to appreciate the sonic difference, and sold it as well as...

Hi is the VC02 discontinued?  Amazon no longer carries them.  And what is it being replaced by in the lineup?

This review from a great but non-Headphone recommendation site http://www.kk.org/cooltools/archives/005854.php#disqus_thread has me wondering if anyone on head-fi had tried this Coby headphone yet.  $30 and active noise cancellation?  Sounds like a possibility for investigation, at least.  ...

DjPhysix: Did you get the PP from Full Compass yet? Were they the 25th Anniv ed?

Oh, SLA battery is way too big. The box itself is about 4" cubed. I am thinking 2 to 4 AA's to power, since I can barely squeeze in a 4AA holder. I suppose I can DC-DC boost to whatever operating voltage is, but would prefer not having to worry about power supply side too much.

I would like to build a simple amp to drive a simple 8ohm speaker housed in a small box, for very casual listening from an iPod. The considerations are that it's cheap, small, and battery powered. I researched turning a CMoy into such a beast, but in an old thread AMB pointed out that you may...

Thanks for the suggestions. Thought about using the DIP version, or building OpAmp based approach, but just not quite ready to deviate from Tangen'ts foolproof instruction for my first build. Definitely reminds me that there are always more than one way to skin a cat though. Ended up just...

Cool! Already have a TI sample account, so I'll go get that sorted out while I wait for the backorder. Thanks!

Both Mouser and Digikey are out of stock, and I just got an email from Mouser saying that they don't expect any until end of March. Does anyone know of a source for them? I'll settle for one just to get my first CMoy going. Thanks.

I didn't think he was misbehaving this time. We post at the pleasure of the moderators, I guess.

Care to write up how to do DIY anodization? Sounds like a good thing to know.

I'm sure GV6 is awesome, but at $55 the GV5 is a steal. Building a CMoy will probably run you $25. I also wonder if the AD8397 is the reason why the sound is improved over the V5. if so, the V5S is a good bargain since you can probably roll a AD8397 anyway.

Can someone help me understand why some headphone amps are more suitably used as preamps? I've seen that mentioned a few times here or at other forums, and I never understood it. I'm guessing that preAmp is a current multiplier, and so is a headphone amp, and a power amp is a voltage...

Wouldn't a spray of lacquer or some coating prevent the rust?

The small business scenario is a hypothetical situation. I don't think I or anyone has said that this company is a small business. Which is why this thread should just get moved, because as the poster above said, it is not about headphones or DIY anymore.
