Discounts, codes, and cashbacks are limited-time promotions in which you can save a lot of money. If an item is on sale, you will see the new price right next to the old one. If a discount code applies to a product, you will find it in the category listing above the product price or in the product details below the image gallery. You must then enter the discount code in the "Use discount coupon" field before submitting your order. Items with a cashback option are also marked in the same way. If certain conditions are met after purchasing these products (e.g. registration of the goods on the manufacturer's website), you will receive part of the total price back. You can find out all the terms of the specific cashback policy in the product details.

Speakers are electro-acoustic transducers. The scientific name tells us that the speaker is a device that converts electrical impulses into sound. It consists of a magnet and a diaphragm for converting electrical signals to sound waves, then radiate them into the air.
The human ear can hear sounds at frequencies from 20 Hz to 20 kHz. Therefore, speakers are constructed to encompass this ideal sound spectrum. The lower the frequency, the deeper the tone. It is very effective for movies with action and explosions etc., and for listening to music with deep bass and drums.
