Bad Guy Good Audio Reviews (A Million views?) Part 3/4

How long did these take to arrive from order? The full 6-7 weeks?

That sounds incredible!:joy: I have been really looking forward to get that live performance feeling from it when it arrives​:sweat_smile:

I appreciate the trust over the years.
Thank you :raised_hands:

Damnn that was a quick response! Happy for you! I ordered mine direct from there so I guess I will also get the card along with it? Good this was handled quickly, I wasnt planning to change the cables anyway but good to know if i have to I should be careful :sweat_smile: cuz i am a clutz :rofl:

4-6 weeks is probably the safe range. Purchased in the 13th of Sept. Shipping took like 2 weeks for customs.

Nice addition by FatFreq! These instructions directly included in the packaging is a smart move—especially for those of us who switch cables often.

Totally agree. crazy how far budget IEMs have come! Makes it easier for more people to enjoy quality sound without breaking the bank. Thanks for sharing

I can produce myself for very long and probably just guess or/and be wrong.

In the long run there is always amazing walking encyclopedia Oratory1990 that most likely answered all the questions like that already. His subreddit is such a nice source of information if anyone wants to get into the weeds of technical limitations, bullshit in marketing materials of IEMs etc

Here are 2 examples for free of charge sweet, pure knowledge

With a fully open back volume you lose a few parameter relevant for tuning.

One of the tuning parameters in an in-ear headphone is the size of the back volume, as well as the diameter and length of the venting hole in the back (connecting the back volume to the outside).

By making the back volume smaller, the enclosed volume of air becomes stiffer, and this stiffness acts onto the loudspeaker’s diaphragm. This increases the loudspeaker’s main resonance frequency and lowers the SPL below the resonance frequency.

So with the size of the back volume, you can adjust the main resonance frequency and the rough balance of of frequencies below and above that. Typically the resonance frequency will be at around 3 kHz, since that’s where the most energy is needed with conventional in-ear headphones.

By adding a venting hole to the back volume you create a Helmholtz resonator (the helmholtz resonance frequency being determined by the size of the back volume and the length and diameter of the venting hole, as well as any damping added to the venting hole). At frequencies above the Helmholtz resonance, the venting hole will be closed, as the resonator does not let air pass through the vent.
But at frequencies below the Helmholtz resonance, the venting hole will be open, letting air pass through it. This also means that the effective back volume becomes larger (and its stiffness becomes lower) at frequencies below the Helmholtz resonance, since the air does not have to compress, it can instead “escape” through the vent.
This means that we can use a back volume venting hole to reduce the stiffness at low frequencies, which allows the loudspeaker to excurse farther, creating higher sound pressure level below the Helmholtz resonance frequency.

This means that if we use both a small back volume and a venting hole in the back volume, we can effectively create a bass boost, by reducing SPL below 3 kHz and then adding it back in below, say, 100 Hz.

So, what is the problem then with using a fully open back volume?
This means that we can not use the back volume to dial in a bass boost anymore, so the frequency response will be flat below the resonance frequency. The vast majority of people prefer a significant bass boost on in-ear headphones, so the market will automatically be quite restricted.

Lol, this is one of the very few things I use my stylus for :smiley: But no regrets

I have seen folks on Youtube remove IEM from packaging by grabbing earhooks to pull em out. That’s a good way to start a big problem.
I don’t think any set should break but that 2pin socket can render a set useless so folks should go slow and easy when cable rolling

I know I bought 2 Tanyas just for the filters due to the Olina.

Hey Chris,

So I just received my Deuce and… it came with no box, accessories, no first 150 engraving case, nor the blood cable, in-fact, it came with literally NO CABLE. The barebone minimum.

I’m very disappointed after waiting 3 months for this, brother.

I recognize that leather case from the upsell site they put together for addon accessories, because I’d considered getting it. Extremely strange.

Edit:
Yep, found it. It’s this one.

You ordered as a regular customer? Not a review unit?

Regular customer



Ordered confirmed on July 23rd lmao :skull:

This is extra weird IMO as the “standard” version listed on Amazon/Linsoul doesn’t even have that style of case:

Saw you already answered this on your thread. It’s going to be interesting to hear what they have to say about this😅

My mate who ordered his duece a few days after me still doesn’t even have a tracking number.?!!:man_shrugging:

Yep, that’s why I pointed it out. That’s their most expensive case for it. A good chunk more than the metal case, and a whole lot more than that little cheap nylon case in that screenshot you linked. Just makes the whole thing extra, extra strange. Like they pulled his order out of a claw machine of random pieces.

Come to think about this. What if you where a random buyer, without any knowledge of the set! Hope this is a one off fuc*up, and not something that happens to more people!

Edit: typos
