Unfortunately, these cannot be connected to the Playstation 4.

Thanks for your tip. You are right. I have passed this on to the relevant department for correction and it will be dealt with as soon as possible.

Hi Budii_11, yes, the headphones are compatible with the iPhone (IOS devices). Registering the device you want to connect to is called "pairing". You should first pair a device before you can use it with the headset. Please note the following before starting the process: -The iPhone is within 1 metre of the headset. -The headset is sufficiently charged. -The iPhone user guide is ready. 1-Take both units of the headset out of the charging case. The headset switches on automatically. Please note that the indicators (blue) are flashing. 2-Switch the headset to pairing mode. If you are pairing the headset with a device for the first time after purchase or after you have initialised the headset (the headset has no pairing information), the headset automatically switches to pairing mode as soon as you take it out of the charging case. In this case, continue with step 3. -If you are pairing a second or additional device (the headset has pairing information for other devices), press and hold the buttons on the left and right units for about 5 seconds. Please note that the indicator light (blue) on both units of the headset will repeatedly flash twice in succession. You will hear the voice prompt "Bluetooth pairing" from both headset units at the same time. 3-Unlock the iPhone screen if it is locked. 4-Search for this headset on the iPhone. -Please select [Settings]. -Tap on [Bluetooth]. -Tap the switch to switch on the Bluetooth function. 5-Tap [WF-C500]. -If a password (*) must be entered, enter "0000". -The headset and the iPhone are paired and a connection is established. -The indicators (blue) on both headset units will flash rapidly for about 5 seconds. -You will hear the voice prompt "Bluetooth connected" from the headset unit that was first removed from the charging case.

👍👍

Hi Philipzbinden, we are sorry to inform you that these headphones do not support this option. Each unit is suitable for specific side (right or left). However, you can use the left unit alone while the right unit remains in the charging cradle. If you use only the left unit, operate the connected unit to play music. In this case, you can adjust the volume with the button on the left unit. You can find more information about the functionality online on our support page. Sony Europe

Yes

The best thing is to contact Sony directly, they will be happy to help you.

Hi, my headphones rarely last, but I've gone jogging with them several times and they fit very well. I always need the smallest attachments.

Yep, no problem to connect them to my android phone (Nokia with Android One). All the functionalities and buttons work ;)

It didn't work for me. I connected it to the mobile phone, but the connection with the tablet didn't work right away, but I didn't search or research further in the settings, but gave up immediately.

Kein problem

Yes, they are compatible. You can find instructions here: https://helpguide.sony.net/mdr/wfc500/v1/en/contents/TP1000445859.html
