Earphones

Types of earphones

• Closed-back earphones

  Closed-back  earphones

  Have a non-vented back. The closed structure isolates the listener from the outside world by blocking out ambient noise. Closed-ear headphones offer noise canceling because, in a wired model, the drivers face inward, creating a seal around the ears. For music, this design enhances bass frequencies. The closed design prevents sound leakage so others don't hear what the wearer is listening to.

  However, the closed design can cause earcups to become hot and sweaty. It affects the sound's naturalness. Artificially altered sound can, at times, lead to listening fatigue. People using closed-back earphones for extended periods may experience pressure discomfort.

• Open-back earphones

  Open-back earphones

  Have a vented back that creates a natural listening experience. They provide consideration and feel like the sound comes from outside rather than inside the ears. Acoustic design improves sound quality. Open-back earphones create a natural sound that is not distorted and may slightly enhance the bass.

  They are less likely to cause earcups to sweat or feel warm when worn for a long time. Open-back earphones are lighter and more comfortable to wear. Their design, however, has some drawbacks. The sound may bleed, preventing others from hearing what the wearer is listening to. Because of their less insulated design, open-back earphones offer no noise-cancellation effect.

• On-ear headphones

  On-ear headphones

  Have a simple and unique design. The earcups are neither too large nor too small, making them comfortable ears. On-ear headphones are portable because of their small size and can be folded. They are lightweight, so wearing them for long periods won't cause ear fatigue.

  However, their lightweight design makes them less durable. On-ear headphones also don't cover the ears fully, which may lead to sound leakage. Long wearing can cause ear discomfort and, in some cases, depress the ear.

• Over-ear headphones

  Over-ear headphones

  Have bigger earcups that entirely cover the ears. Over-ear models are comfortable to wear and don't cause depress or pinch the ear even when worn for long hours. Because of their bigger size, over-ear headphones are less likely to cause ear sweat and fatigue.

  Although they are comfortable to wear, people using over-ear headphones should take caution. Over-ear models can become hot and cause sweat around the ears. The design of over-ear headphones also has some noise-cancellation effect that interferes with the natural sound quality.

Features and functions

Wholesale earphones can come with various features depending on customers' preferences. Here are some of the standard features:

• Sound Quality: Good earphones should have clear quality audio for both users enjoying music and content creators rendering pure sound for their audiences. Quality earphones have a good frequency response that minimizes audible distortions.
• Frequency Range: The frequency range of earphones determines its sound output. The standard frequency range for earphones is between 20Hz up to 20kHz. However, some earphones can go lower than 20Hz or even as high as 40Hz. A lower frequency means the earphones can produce deep bass sounds, while a higher frequency means the earphones can produce high pitch sounds.
• Spaalty Impedance: Impedance determines how much earphones resist the electric current flowing through them. A high impedance value means the earphones will have superior sound quality but will need higher power levels from the source. On the flip side, a low impedance value means the earphones will require less power from the source. Generally, earphones meant for portable devices like phones, tablets, or laptops have a lower impedance value. In contrast, those intended for use with professional audio equipment have a higher impedance value.
• Closed Back Design: Closed-back earphones feature an enclosure that covers the earphone driver completely at the back. This design prevents sound from leaking out or external noise from entering. Closed-back earphones is an ideal choice for noisy environments or when one does not want to disturb others with sound from the earphones.
• Open Back Design: Open-back earphones have a perforated housing that allows sound to leak out and enter. This design creates a more natural and realistic soundstage. However, the sound can leak out and the surrounding noises can be heard.
• Charging Case: Wireless earphones usually come in a portable charging case. The case serves as a charger when the earphones run out of battery. It also provides extra battery life because most charging cases have large battery capacities compared to the earphones.
• Bluetooth Connectivity: Most wireless earphones use Bluetooth to connect with audio source devices. The recent Bluetooth versions (version 5.3) provide stable connection and longer ranges compared to older versions like Bluetooth 4.2.

Usages of earphones

Based on different designs and types, earphones can be used in many scenarios. Here are the key applications:

• Entertainment: One of the most common uses of earphones is for entertainment purposes. People use earphones to listen to music, podcasts, or audiobooks, and watching movies.

Sometimes, they connect them with a stable internet connection so that they can play online games without any distractions or noise.
• Work and Productivity: People often use earphones to help them concentrate on their tasks or to participate in virtual meetings. This is mostly common among freelancers or professionals who work from home. Furthermore, some people use earphones with noise-canceling features to block out any background chatter that can probably distract them from working efficiently and meeting deadlines.
• Working Out: People wear earphones when exercising to stay motivated by listening to music. They can use the sports earphones, which are sweat-proof, stable, and comfortable, or the noise-cancelation ones to avoid any distractions.

Many people connect them to their PCs or mobile devices to make calls, participate in online meetings, record voice messages, or use voice assistants. This can be in different scenarios, such as when they are busy with their hands or in a noisy environment.
• Ambient Noise: Some earphones, particularly the open-ear ones, allow users to hear the surrounding sounds while listening to audio. This can be helpful for outdoor activities, as users can be aware of their surroundings while enjoying their music.
