The official Philips page for this new headset is right here, and you can also find it at select retail partners. I got this headset from Amazon. In the box you’ll get the headphones, some basic instructions, and a 3m rubber-covered detachable cable that’s tangle-prone and resilient. Luckily, both ends use industry-standard non-proprietary 3.5mm plugs, so finding a replacement cable is super easy if you decide an existing cable isn’t serving your needs. your request.
The only other included accessory is a very basic 6.3mm quick-adapter plug with a rubber grip on it. Despite the handle, the adapter feels oddly cheap compared to the nice logo-printed plug it attaches to, so I think Philips is expecting you to use them with the connection 3.5 mm. If they omitted the standard gold plate and applied a layer of silver or nickel on the adapter, it would enhance the aesthetics considerably.
