Hello, What is the Bitrate for these headphones? Also I am looking at the frequency chart on the official webpage, and it cuts off at 20hz - 20khz. There a way to see how this performs from like 10hz to 40khz? Thank you

I think you're confusing bitrate, sample rate, and frequency response.
Bitrate is simply how much digital data is stored or transferred per unit of time. For example an MP3 file will commonly be recorded in bitrates of 128kb/s (kilobits per second) or 192kb/s.
Digital auto streams also have bitrates, so audio devices that transfer audio data digitaly, like bluetooth headphones, will have a bitrate that will vary based on the codec used. The common AptX bluetooth codec can get up to 352 kb/s.
As Nismo 3Ds are analog IEMs, bitrates aren't a factor for them; your audio source will have already converted the digital audio to analogue.
Sample rate is related to bitrate; it's how often the original analogue audio source is sampled when creating the digitial audio file, measured in hertz. For instance, CDs are mastered at 44.1khz meaning that the original analogue source was sampled fourty-four thousand and one hundred times each second to construct the audio file on the CD. A higher sample rate makes for a higher bitrate (all other things staying equal).
Sample rate is (generally) only a factor when creating a digital audio file, and doesn't have anything to do with headphones.
Frequency response is the range of sound waves that a speaker/driver can produce, with lower freqencies being bass, and higher frequencies being treble. An average adult human can hear sounds from around 50hz at the low end to around 15,000hz (15 khz) at the high end.
These Nismo 3D IEMs definitely cover the full range of human hearing very well, with a focus on bass, but also good sound reproduction on higher frequencies too.
No headphones are designed to cover from 10hz to 40khz as that ranges WAY outside the range of human hearing on both ends, so there's simply no need to design for those requencies.

They are analogue so bit rate depends on the device you are plugging them into. 20hz - 20khz is all a human can hear and anyone telling you otherwise comes from marketing and you shouldn't believe them.

Should I exchange the PC38X for better headphones?
I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Looking for a gaming/content audio setup
Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

$10 Drop Coupon Email not sent?
Trying to buy some gear off Drop for the first time. I was told I would receive an email with a welcome to drop $10 off promo. I never received that email. Drop was able to send me emails for my login token and email for Password update. But for some reason the $10 off coupon was never sent to me.

New here
Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.
