1. Drive: Wired Headsets are driven by audio equipment, so they can achieve high driving effects, while Bluetooth headsets are driven by batteries, often only up to 4.5V, and can't actually reach 5V.
2. Profit: Bluetooth Headphone are often linked to technology, so they seek high profits under the guise of technology. Ear Wired Headset technology is relatively mature, so the profit is very low.
Summary: If the focus is on sound quality, it must be wired Cell Phone Headset. If you choose In Ear Earphones or headphones, the headphones must have good sound quality at the same price. The larger the speaker, the easier it is to drive, and the easier it is to adjust the sound quality.
The sound quality of headphones is not divided according to Bluetooth and wired. 1. Signal-to-noise ratio, in general, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal, and the higher the sound quality of the sound playback, otherwise the opposite. The signal-to-noise ratio should generally not be lower than 70dB.
3. Computer Headphones sensitivity, the higher the sensitivity, the lower the power required to reach a certain sound pressure level. Now the sensitivity of moving coil monitoring headphones is generally above 90dB/mW. If you choose headphones for Walkman, the sensitivity is the best around 100dB/mW or higher.
4. Frequency response, refers to the frequency range that the headset can perform. The general value is 20-20000Hz (bass-treble), such as 12-39000Hz, which means that this Bluetooth Gaming Headset can show more audio details and the sound is "more real". 30-17000Hz means that the earphones cannot distinguish the details of the audio segment below 30Hz, but the bass effect is very "heavy" and has weight, and the treble situation is similar.
5. The total harmonic distortion indicates the stable, clear and fidelity of the sound quality of the earphone. For example, the indicator of a certain earphone marked as "less than or equal to 0.1%" is quite good, and the general earphone is about 0.7%. Small is better.
