We will skip the first four because Siemens has stopped their production and their specifications are very limited. 1 - Earphones with the number (3): This category of earphones has limited company value and thus very limited technology. It does not solve all hearing loss problems, and I do not recommend it. It has 24 audio channels. 2 - Earphones with the number (5): This category is advanced and suitable for most hearing loss problems. It has 36 audio channels. 3 - Earphones with the number (7): The excellent or very advanced category. This is the highest category in terms of available programs and is considered a revolution in the manufacture of hearing devices from Siemens. It has 48 audio channels. ************************************************ - The earphones have a wireless feature that helps coordinate between the right and left earphones, understand speech, and determine the direction of sound. - Please, before calling, search the internet for the model number registered above for the specifications of the earphones and the number of channels they contain. - Whoever wants clearer pictures than those shown here, message me via WhatsApp. _The earphones can be sent anywhere you want via DHL through express shipping, within two working days, as shown in the pictures below the screen. +++++ ((There are several ads for medical earphones, check my ads)) +++++ The requested price for the earphones is 2000 riyals, and this price is final with no negotiation.
