  1. Both have equally good microphones and comparably poor sound output. The HS50/60/70 is still the best-sounding headset Corsair has made by a decent margin, though the bad microphone and ergonomics make them hard to recommend generally.
  2. Motherboard DACs are pretty bad, but it's indeed more important to get a better amplifier because motherboard headphone amps are even worse. With higher impedance headphones it may not matter as much; although they won't get as loud out of a motherboard, the integrated amplifier doesn't distort as much into the high impedance load, and the high output impedance doesn't alter the headphone frequency response as much. You can indeed plug a 3.5mm to RCA cable from the PC to the amplifier. The motherboard's Realtek codec can usually digitally process files up to 24 bit 1
  3. You're not going to get tactile bass from headphones in general without damaging your hearing (and getting a heavily distorted output – headphones ideally dampen bass vibrations!). If you want tactile bass, use speakers or a tactile transducer. For an argument (which I recognize you may not necessarily be making) that larger headphone drivers can give a significant tactile bass response, try the following experiment. Put the headphones (go ahead and whip out the 100mm planars) on your ears, play a 50Hz tone, and bring your headphones to a reasonably loud level (without audibly dist
  4. The tiny drivers also have to move a much smaller volume of air. PV=nRT -> SPL ∝ 1/V. It's much easier to get large bass response from in-ears because the air volume reduction is greater than the displacement volume reduction, but the bass goes away significantly if the seal with the ear is imperfect. This is true of closed-back headphones in general as well, but not to the same extent. Sometimes headphones with wired/wireless options use an ADC -> DAC combination rather than allowing you to passively power the drivers. This signal chain usually causes more spuriae than decent mo
  5. Are you sure you're getting a good seal with your eartips? The P2 should be fairly neutral with a bass boost. (from Rtings.com) The original Galaxy Buds are close to perfectly Harman-neutral and are reasonably priced in most markets, if you just want conventionally good sound quality in a TWS at a decent price.
  6. The PC had 3 GTX Titans and they used a script to make the PC and space heater use exactly the same amount of power. I think the real takeaway is that the PC's heatsinks and fans let it circulate hot air faster than the space heater can.
  7. So, I just went out and tested it. I have both a 4 pole and 3 pole cable for my HD650. Plugging into my phone, motherboard, and front panel it sounds identical using either cable. Plugging into a cheap Y-splitter with the 4 pole massively reduces the volume and makes the audio sound like it's underwater (plays the difference between channels while cancelling mono content, indicative of high ground impedance). Pressing the volume control and microphone buttons somewhat fix the problem because they work by swapping a lower valued resistor into the microphone line, confirming that the
  8. That's where the codec itself comes in. I settled on 1Vrms for the calculations above because it is representative of the most common chips. Devices with different output levels are still common. Absolutely true. Newer high end motherboards have around double the power output and significantly lower distortion into low impedance loads from the headphone output, while older designs sometimes have astronomically high output impedances from their line outs. There is still a ground to ground connection when plugging TRS intro TRRS or vice versa. Grounding the microphone contact is
  9. For the impedance numbers it's from a sample of measurements online. Although not all devices use those output impedance values, they are common in their classes. For phones very low output impedance is common. Samsung S10 2Ω. LG G7 1.6Ω. iPhone 5S 2Ω. Keep in mind that impedance measurements this low are usually inflated compared to the actual value due to cabling and connections. For laptops it's difficult to find people who have measured these. HP Z laptop 17Ω. Dell Inspiron 7548 23Ω. Lenovo G770 17Ω. Some laptops certainly use higher or lower value resistors (usually still be
  10. For starters, most cheap audio codecs are rated for 1Vrms output, whether it's a phone, laptop, desktop, or USB dongle. The output qualities may differ greatly between different models, but the loudness of all of them, if they were used in the same circuit, would be similar. The issue is probably almost entirely output impedance. Headphones get louder (and reproduce sound more neutrally) from sources with lower output impedances. Motherboards virtually always use 75Ω resistors on their headphone outputs, while many laptop makers user smaller values. Most phones omit the resistors,
  11. The QC35 is slightly more comfortable but has slightly worse noise cancelling. Personally I find the hardware buttons a lot easier to use than the touch interface on the Sonys. Otherwise if you need ANC the Sony is still a good option, especially at the used prices you can get the 1000XM3 for nowadays. Personally, I'm not convinced that anything was actually upgraded on the XM4 compared to the XM3; in person I didn't notice any significant differences, and in measurements they're within margin of error of each other in basically every category.
  12. The Airpods Max clamp harder than the XM3. Bose headphones have some of the lightest clamping forces around. You can bend the XM3 headband to significantly reduce the clamping force. The very top portion (where the padding is) has no rigid plastic parts, just a flat metal strip covered in foam and pleather. Bending the headband far enough permanently deforms the metal strip. You could probably do the same thing with the Airpods Max, though I've never attempted it. I have not listened to the QC45, but IMO the QC35 was a better headphone in every respect than the Airpods
  13. Bose QC25 is the only reasonably high-performance wireless headphone I can think of that has a replaceable battery, but it's not suitable for gaming. The G533 battery pack isn't soldered and is accessible from the outside of the cup without any tools; if your main goal is to be able to quickly swap in a charged battery after it dies, that might be an option. Extra (used) batteries are $16 on eBay.
  14. Moisture evaporates quickly; as long as you don't get any spit in there no residue will be left behind afterwards.
  15. Do both channels sound the same or is one worse than the other? Quiet tube sound makes me think that the one or both of the channels have shorted, leaving only the difference between the two channels as what's being played. Test if the sound is better when you only play music through one channel (test both channels). As for the dent, you may be able to fix it by blowing gently to inflate the driver through the holes in the back. I've done it a few times when modding my HD650, but I don't know how well it will work with the DT770. You're lucky you didn't damage the ampli
