Unfortunately, the Oura Ring 4 does not support contactless payment.

The ring size is 4. This size is part of the available range for this smart ring, which comes in sizes 4 to 15 without half sizes. The sizing is specific to this generation and differs from previous models, so using the correct sizing kit is recommended for an accurate fit. The ring weighs approximately 5.20 grams and is made of metal with a pink gold colour.

Hello, yes, it lights up just like the Oura 2.

It looks pretty much like the one in the picture - a bit shiny but not like a mirror or the normal black ring. In my opinion it's more of an anthracite colour. Unfortunately there is no possibility to send you a picture.

Hello Charging station with USB-C cable is included, but no power supply unit.

The QR code is displayed in the instructions for use and refers you to the Oura app (you can also find it yourself in the store). After a free trial month, you can then start your membership as a monthly or annual fee. Everything is simple and straightforward.

No, this ring does not have integrated NFC. I would also advise against buying a ring with NFC because of the security.

Yes, the charger is included in the scope of delivery.

Since your ideal size is 7.5, I recommend choosing a size 7. This fits well with cool hands and will not be too loose with warm hands as your fingers will expand slightly. A tighter fit will prevent the ring from being too loose, making it easier to take accurate measurements and prevent slippage.

Unfortunately, this is not possible as we do not have these rings on display in our shops.
