Below (even ermittel, no guarantee) some information on the dimensions:
The oval handsfree clip is about 9 cm long, max. about 4 cm wide and approximately 2 cm high (with the still firmly attached to the housing clip added).
The rectangular display measures approximately 4.2 x 2.6 cm.
Total weight: about 65 grams.
Arranged laterally on one side are the two adjustable loudspeakers / down buttons and the On / Off shift knobs.
On the top you will find below a flexible cover the common connection for the charger and an external headset, if you do not want that the environment overhears the conversation.
As unnecessary mistakes and I feel that you always have to reset the date and time after switching off. Also why I leave the clip on call.
The operation of the display is sometimes a bit difficult for me, as the touch screen a bit cumbersome responding or needs appropriate pressure. Especially when dialing phone numbers it is with broader fingers bit fiddly, so it offers a pen-support here. And come to the unfortunately limited arg phonebook memory holding only the most important numbers. For these reasons, the clip for me is not a full replacement for the handset my phone (Siemens Gigaset C475), which I continue to use mainly for calls.
The Sign of the clip at the base station by the way went smoothly according to instruction in two minutes.
Operation and settings are largely self-explanatory.
Important: When the on-hook function can set whether you want to confirm this (by pressing Hook). I have disabled it.
My conclusion: In spite of the aforementioned shortcomings of the Philips hands-free clip is (so far) a highly recommended product that gives me plenty of space and an excellent voice / audio quality when making calls. As a full-fledged handset replacement I see the clip only when you need little Teleonbucheinträge and / or is called more frequently.
