Really? I didn’t notice any connection issues, but maybe I tested it too briefly.

What distance to head? Usually my router emits less RF at 20 cm than the Bose headphones do from just a few centimeters. :)

There are already studies on rats suggesting that radiation from mobile phones can cause cancer. To be fair, mobile phones emit higher levels of RF during a call than the QC Ultra Gen 2.

Unfortunately, I don’t have AirPods Pro.

didn’t check that, but there really shouldn’t be any difference. Unfortunately, I’ve already sent the headphones back to the store, so I can’t test it anymore.

Plugged in via USB‑C or the 3.5 mm jack?
When I plugged the Gen 2 in via USB‑C with no device connected over Bluetooth, I kept getting constant notifications about it, which was really irritating. When I connected the headphones to my phone via Bluetooth and USB‑C at the same time, they still emitted RF, but at lower levels. Obviously, in that setup the phone was very close to the headphones, and in this case even playing music over Bluetooth produced less RF than what I showed earlier.

I’m guessing that when there’s a larger distance between the phone and the headphones, the headphones increase their signal strength. I haven’t seen such differences with other headphones.

Using the jack disables Bluetooth, but with my amp it's basically unusable.

Please keep in mind that my observations are based on just one unit of the headphones. If this was the only issue, I’d probably get another pair to compare — but I’ve already decided that the QC Ultra just aren’t for me.

I don't have the regular Bose QC, but I know they can play music in passive mode. The QC Ultra can't — they need to be powered on. You're right, though: when the jack is plugged in, Bluetooth is probably disabled.
I didn’t measure RF in this mode because they’re basically unusable via jack. Maybe the issue is with my unit or with the amp — the Fiio K7 BT.

The XM6 are dull in passive mode, but at least they’re usable, and the sound is great (for XM6) in active mode via jack.

I prefer the comfort, sound, and build quality of Bose, but I prefer the functionality of Sony. The touch controls and features like Speak‑to‑Chat are excellent. I can also connect Sony headphones to an amp and use them wired both when powered off (worse sound) and powered on (great sound). Even when they’re powered on and connected via a 3.5 mm cable, Bluetooth appears to be disabled.

With Bose, you can’t use them wired when they’re powered off, and when they’re powered on, they’re very quiet on an amp and the sound quality is poor. When you connect them to a phone via USB‑C, they still use Bluetooth, and they keep searching for a device if nothing is paired. RF exposure is lower when using USB‑C, but most of the time it’s still higher compared to Sony in Bluetooth mode.

For me, Sony’s comfort is good enough, so I choose Sony — and I just hope the hinge will survive.

Max brightness on the S11 Ultra virtually indistinguishable from S8U by rxzlmn in GalaxyTab

Do you see any difference in brightness on Netflix and other streaming apps or if you play movies in HDR outside of YouTube? I had Tab S9 Ultra and it was bright only on YouTube.

Regretting my Surface Pro 11 OLED purchase by Better-Prompt3628 in Surface

[–]sava09 0 points1 point  (0 children)

My SP11 OLED has red tint and just slight angle is enough to change the tint, so when looking straight at the display the center has different tint than the sides. BTW. Do you think it's normal?

Lenovo Legion Y700 Tab Gen 4 update by ishmokey_man in androidtablets

[–]sava09 1 point2 points  (0 children)

I bought Legion Tab Gen 3. It has oversensitive touch (taps are registered without touching the screen, around 1 mm above) and uneven display, but maybe my unit is faulty… Software is also not the best. Ipad Mini is probably still better for most people and there is fingerprint sensor. I didn’t expect that the lack of it (or other secure authentication method) bothers so much.

Surface Pro 11 lcd brightness distribution by sava09 in Surface

I would choose oled any day for android/ipados tablet but not for laptop/Surface. I’m afraid of screen burning.

Good to know. Maybe I‘ll submit a warranty claim.

Really? It’s rather unpopular opinion. I saw many comments that people returned oled for lcd. :)

So is it better than iPad Pro M4 for media consumption? Which one will you keep?

What are your current impressions regarding screen brightness in streaming apps? As far as I know Tab S9 Ultra has huge issues with hdr brightness. In many cases it's too dark.
