I'm trying to figure out what makes HE-5XX, Ananda, or Grado GS more breathable than other open-back headphones. It's not clear from looking at their pictures.

ATH-AD900X appear to have see-through earcups

I am looking for breathable over-ear headphones. So far, I found: 1. Sony MA900 has hole in earcup 2. Sennheiser HD700 or HD800 series in addition to open back volume has open front volume - metal mesh in front of the driver 3. VIE SHAIR has open earcups 4. AKG K1000, MYSPHERE 3 5. Maybe...

How easy is it to drive ATH-R70X? The impedance is 470 ohms.

I am looking for headphones with the best ventilation to keep my ears cool. Ideally they should also be able to be driven from a portable amplifier, like FiiO BTR5. I would also like them to respond well to EQ, so that I can increase the bass response. Sony MDR-MA900 seem great, but it is...

You can also connect 2-pin or MMCX headphones to FiiO UTWS1. Perhaps modding Koss headphones to connect them is an option. If you can compromise on true wireless, then consider Koss KSC35 Wireless or Koss BT221i.

I don't have any of the Philips Fidelio headphones at the moment. I am deciding which ones to get.

Human Headphones are true wireless, but they cost above £50. I have not listened to them.

Does Philips Fidelio X1 (or X1s) have better ventilation than X2 (or X2HR)? I would like to prevent my ears from getting hot while listening for hours, so I would like to pick the more breathable headphone.

Would the following cable really make Philips Fidelio X2HR or X1s work with a balanced amplifier? The product does have good reviews. https://www.aliexpress.com/item/4000316198773.html I think that in order for it to work, each of the drivers has to take the ground signal from two different...

It's awesome to see this thread going for a few years! Thanks for the recommendations! I think I should also consider headphones that are both open front and back to get the most ventilation, such as HD 800, as described here...

Is the Fidelio X3 casing in front of the driver also open? An example of an open front headphone is Sennheiser HD 800, as described here: https://www.reddit.com/r/headphones/comments/6sqrys/what_exactly_are_semiopen_headphones/

I hope this is not too off-topic. So, headphones, such as RHA T20i, which are marketed for Apple devices, should have CTIA-compatible controls (rather than OMTP) and should work with FiiO BTR5?

Does the FiiO BTR5 support line-in controls on headphones for Apple devices (both as Bluetooth and USB DAC)? I am referring to the ones that use OMTP, rather than CTIA (reference: https://mashtips.com/apple-headphone-on-android-or-windows/ )

Is using the equalizer or various DSP settings directly on the Bluetooth adapter superior in any way to using them on the device, which is playing the audio, such as smartphone or a desktop computer? Perhaps, the lack of equalizer support for LDAC on the FiiO BTR5 is not much of an issue, given...
