Wireless charging is a technology that allows you to charge your devices without the use of cables or wires. Instead, wireless chargers use inductive charging to transfer energy from the charger to the device. Inductive charging works by using an electromagnetic field to transfer energy between two coils. When the coils are properly aligned, the charger will emit a magnetic field that can power the device. Wireless charging is popular because it is convenient and easy to use. However, there are some limitations to this technology. One of the biggest concerns is that wireless chargers can overheat and damage devices. In addition, wireless charging is usually slower than traditional wired charging. Despite these disadvantages, wireless charging is a popular option for many people, and it is likely that this technology will continue to improve in the future.
Let's delve deeper to know more about wireless charging.
How does Wireless Charging Work?
Wireless charging is a process by which an electrical device can be powered without the use of physical cords or wires. Instead, the device is placed on a special charging pad, which uses electromagnetic induction to transfer energy from the pad to the device.
The advantage of wireless charging is that it is much more convenient than traditional methods, as there is no need to mess with cords or plugs. Wireless charging is also generally faster and more efficient, as there are no energy losses associated with the transfer of power. Despite these advantages, wireless charging has yet to gain widespread adoption, due in part to the high cost of the technology. Nonetheless, it is likely that wireless charging will eventually become the standard way to power electronic devices.
The advancement in technology has provided different standards and speeds for wireless charging headphones.
Wireless Charging Standards
- Qi Standard
The Qi standard is the most popular and common standard for wireless charging that almost every company employs in its products. It was first introduced by the Wireless Power Consortium in 2008.
The Qi standard uses magnetic induction for generating power and charging the headphones. The devices following this standard support up to 15 watts of power. You can use this standard to charge your Qi-compatible devices, including headphones, from any Qi-certified charging pad.
- PMA Standard
The PMA or Power Matters Alliance is a group of tech companies including Duracell, Samsung, and Nokia. They introduced the PMA standard in 2012.
The Qi and PMA standards are almost the same, but the main difference is in their charging speeds. The devices following this standard can only receive up to 5 watts of power from the transmitter.
- A4WP Standard
The Alliance for Wireless Power or A4WP is another group of tech companies that includes Qualcomm and Samsung. They introduced the A4WP standard in 2012.
This standard also uses magnetic induction to transmit power wirelessly, but it comes with a unique technology known as Rezence. This technology can charge multiple devices at the same time from a single transmitter. It also delivers a power of up to 15 watts for each device.
Therefore, the Rezence technology is quite different from the Qi and PMA standards that can only charge one device at a time from a single transmitter.
How to Choose Wireless charging headphones?
- Built-in coil
The experts suggest buying wireless charging headphones with a built-in magnetic coil to support Qi charging standards. It is the foremost aspect that the consumers should consider because the headphones won't charge if it doesn't support it. For good measure, Soundcore bluetooth wireless earbuds have built-in coils for efficient functionality.
- Fast charging but long playtime
A lot of fast wireless charging headphones are available in the market. The choice entirely depends on the consumer and how long he/she wants to use the headphones after a single charge It is always better to buy headphones offering a playtime of at least 8 hours because you can use them for an entire day without worrying about the battery.
- Surround Sound Effect
Wireless charging headphones shouldn't compromise sound quality. Undoubtedly, surround sound effects is the must need for good bass and an immersive listening experience. Don't compromise on quality for the style.
Wireless charging is becoming more and more popular, as it gets faster and easier to use. It's likely that wireless charging will become the norm in the near future, so we can expect to see even more devices with this capability. Thanks for reading.
