1. Impedance: Keep in mind that in the realm of direct current (DC), the role of objects on the current obstruction is referred to as resistance. However, in the field of alternating current (AC), in addition to resistance, capacitance and inductance will also obstruct the passage of current; this effect is known as reactance. The vectorial sum of resistance and reactance is what we term impedance. In general, low-impedance headphones are preferable. However, to prevent the headphones from overheating or voice coil deformation misalignment caused by broken sound, the volume must first be set down and then inserted into the headphones, and then a little bit of volume up. As a result, Walkman and other portable, power-saving machines should select low-impedance headphones, but also pay attention to the sensitivity of the Walkman indication, which is more significant.

2. Sensitivity: 1 milliwatt of power when the headset can be issued by the sound pressure level (the unit of sound pressure is decibels, the greater the sound pressure, the greater the volume), so generally the higher the sensitivity, the smaller the impedance, the easier the headset sound, the easier to drive.

How do humans perceive sound? Simply said, sound travels through the ear canal and vibrations the eardrum, causing the sensation of hearing to be activated. There is also a bone conduction approach, which sends sound through the skull to the auditory nerve, bypassing the ear canal and allowing the auditory nerve to receive sound. When it comes to the headphone industry, there are the standard headphones we all know and love, as well as several firms that have released bone-conduction headphones.

Although bone-conduction headphones are still considered a niche product in terms of contemporary applications, they have a lengthy history. In 1935, the first bone conduction headphones were utilized in the medical field to assist patients with hearing loss in hearing information from their environment.

Advances in Bluetooth and related technologies have driven the era of wireless Bluetooth audio products, providing users with a more convenient user experience and gradually gaining market recognition. Bluetooth headsets, smart speakers, and other audio products have ushered in a rapid growth phase.

Bone conduction headsets as a very important classification in the current Bluetooth headset market, with an open-wearing experience, different from the traditional headset listening experience, currently mainly focused on the sports headset market. But the development of bone conduction headsets will not only be so, according to its characteristics of the advantages but in the future will gradually be applied to many fields.

This article introduces three main methods, mainly as follows.

If the user is using a desktop assembly computer or all-in-one computer, when inserting headphones or external sound, the first thing to do is to check the "sound card jack". Although the sound card has many jacks, generally pink represents the microphone, and the light green represents the speakers or headphones. If the wrong plug is, even if the headphones are inserted, the computer's sound is still external. Encounter this situation, you can unplug the headset, and re-insert the light green jack can be.

People wear headphones in many situations, such as when listening to music, watching drama, playing sports or fitness games, and so on. Headphones have become a necessity of life. But do you know? Long-term use of headphones, as well as improper use of headphones, can cause varying degrees of damage to the ears.

What is ENC? You might be familiar with ANC, or Active Noise Cancellation, for your headphones, but have you heard of ENC? To start, ENC stands for Environmental Noise Cancellation. This technology is commonly found in headphones with microphones and is not a widely used term. ENC is commonly presented alongside ANC in blogs and videos about headphones and mics nowadays, but ANC and ENC are not the same thing.

ANC is for your own personal hearing; when you’re listing to your music or you're watching the big reveal scene of your favorite movie, ANC takes the noise around you and tries to reduce it so that you can hear your music or movies better. There are a multitude of ways to do so, but the most known type uses a microphone and speaker to invert the soundwaves around you so that it minimizes the noise. In other words, if your noise is at +5, the technology will create a soundwave at -5, and what you’ll hear through your speaker is 0.

Recently, a new technology gallium nitride has attracted a wave of enthusiasm for chargers. Manufacturers are rapidly adopting gallium nitride chargers due to their small size and excellent efficiency. What exactly is gallium nitride, and how does it differ from other types of chargers?

Gallium Nitride (GaN: Gallium Nitride) is a compound of nitrogen and gallium that has particular semiconductor properties and early application in light-emitting diodes. It belongs to the same elemental periodical group as frequently used silicon and has good hardness, melting point, and stability. Gallium Nitride is an important semiconductor material for the development of microelectronic devices, with a wide band gap, high thermal conductivity, and other properties, and is used in chargers that can be adapted to small transformers and high-power devices, as well as having high charging efficiency.

Bluetooth, which was first invented in 1994, has become a technology that we have been familiar with, particularly in the last 10-15 years, corresponding with the emergence of smartphones. Most of us now use Bluetooth to link our smartphones to a home music speaker or wireless headphones when we're out and about. Bluetooth, in a nutshell, is a short-range radio frequency that allows two or more devices to share data and connections.

DECT, or Digital Enhanced Cordless Technology, as it is officially known, was originally published in 1992. Originally intended to give a simple and dependable cordless phone solution. Traditionally, signaling is what permits cordless landline phones to connect wirelessly with one another. Every DECT system requires at least one main base and at least one wireless signal receiver. With headsets, this implies that the base unit will connect to your device (e.g., computer) via cable, and the headset will then be able to be used wirelessly, receiving a signal from the base unit.

The headset, headphones, and earphones are all very similar in design and function, but there are a few crucial differences to be aware of. We'll take a quick look at what distinguishes each of these devices below, and provide consumers with a bit of a guide to help them pick which one they're searching for.

A headset is essentially a pair of headphones that include a microphone. The headset microphone could be a boom microphone, which means that the microphone is attached to a boom that can be moved and positioned as needed. It could also include an in-line microphone. This microphone is connected to the connection that links the headset to the computer or other device.

Headsets are ideal for a variety of applications. They are the obvious choice for voice-over-IP conversations with services like Skype, as well as integrating with a phone system. Headsets are also ideal for playing online games that require audio communication. Listeners who use a headset are completely engrossed in their listening experience.

Are you kicking off the new year with a fitness resolution? Maybe you're just wanting to lose some holiday weight gained from all the family feasts that the holiday season brings? In any case, there are a few clever additions to your exercise regimen (see our post on the top fitness trackers) that can make losing weight or becoming ripped that much easier. Almost everyone at the gym is working out to the beat of their sound system. Take a peek around at anyone exercising, and you'll notice the ubiquitous headphones providing the backbeat of fitness. Major manufacturers, such as Jabra, have taken note of this trend and implemented various unique features to make their devices more in touch with the needs of these users. A good example is the Jabra Sport Wireless+. Let's look at three compelling reasons to invest in a pair of earbuds built exclusively for workout use!
