Lots of friends prefer music mobile phones in order to avoid the trouble of carrying MP3. For a quality music mobile phone, its sound quality is bound to be pretty good. The key to the sound quality is nothing less than these two aspects, decoder chip and earphones. Decoder chip is usually decided by companies, but earphones are by our own choice. Sometimes, we could improve the sound quality by changing earphones.
At present, many earphones accompanied with mobile phones are in segmented structure, divided into line-control part and earphone part. By using a standard 3.5mm interface, they have advantages in interchangeability and flexibility. Users could choose other earphones if not satisfied with this one. These line-control earphones are not limited to a series model of the same manufacturer; they also apply to many other models in other series. Thus, more users are inclined to purchase these "general" line-control earphones. Then, how to distinguish the true from the false?
Methods of identifying:
Line-control: Observe the text or logo on it. Usually, the original is exquisite and smooth, unlike the uneven or rough appearance of fake ones. Play and Pause buttons of genuine products are for outstanding work, while the fake rough. So, pay more attention to observing, you can find the differences easily.
Earphones: The protective film of original earphone is flush with the edge and bottom of handle is made of rubber materials. The fake ones' protective film is concave and the interface is made of plastic. The original ear pads are smooth, not sticky, thickness of the edge, while the fake tacky in a large extent.
Line-divider: Line-divider of original earphones is composed of two semi-circular holes, which could wrap a line for each alone. The positive rubber junction is not obvious. On the opposite, the fake one just has a big hole in the line-divider and a line is stuck out unambiguously in rubber junction. Original lines are relatively thicker and harder, while the fake thinner and hard to be fixed by clips.
2. Listen and touch
Feel the button of line-control: When plugging into the mobile phone, the fake one feels harder and noisy. Also, their line-control buttons and call buttons feel hard and can be heard "click" clearly while using. The genuine one has a gentle voice and the button feels soft and natural.
Listen to the earphones: The imitation sounds depressed as a whole. Their sound is muddy, not enough deep in low frequency, while the original has a full effect in intermediate frequency, strong effect in low frequency and a better resolving capability.
Radio effect: The Imitation has a poor radio effect, not easy to receive radio and has a strong limitation in the direction of the earphone antenna. A slight error in direction will lead to lots of rustlings, which are caused by circuit design.
