How to Choose Wireless Headphones for Your Phone

Major manufacturers are starting to give up on standard headphone jacks. The future is in the hands of wireless devices. Let me tell you about the key characteristics that should be known when choosing a wireless model.

Connection Technology

Wireless headphones receive sound using an RF transmitter or Bluetooth. Which of these options is used by a particular model determines its interoperability with various devices and other connection features.

Bluetooth

If you’re going to use your headphones outdoors, you can choose a Bluetooth-enabled model. Smartphones, tablets, different laptops and other portable devices are also equipped with Bluetooth modules. So you can connect your wireless headphones to them without any additional accessories.
However, Bluetooth is also suitable for use at home: smart TVs and other stationary equipment also sometimes support this out of the box technology. If your TV does not have a built-in wireless module, you can still connect Bluetooth headphones to it. Just buy a special transmitter and connect it to your TV through a regular audio jack.

When selecting wireless headphones for your phone, pay attention to the Bluetooth version. The last one at the moment is Bluetooth 5.0. The newer the Bluetooth version, the better the sound quality and the less power it takes to transmit and receive it and, therefore, the longer the headphones and gadgets connected to them will do without charging.

But for you to feel the benefits of the latest version, it must be supported not only by the headphones but also by a device connected to them. For example, if you transfer sound from a smartphone with Bluetooth 4.0 to headphones with 5.0 (or vice versa), the connection will be limited by the 4.0 version.

Also, if you’re willing to pay more for maximum SQ, take a look at the Bluetooth headphones with aptX technology. Technically, this codec provides the best sound, but not everyone hears the difference in practice. In order for you to appreciate the potential of aptX headphones, a gadget you plug in must also support it.

RF Transmitter

If you choose headphones for your home or office, you can choose a model with an RF Transmitter. These headphones come with a bulky one to connect to your stationary audio equipment.

An RF transmitter consumes more power than Bluetooth, so the headphones usually discharge faster. However, the signal is more likely to pass through physical barriers, which means that it wins over Bluetooth when working indoors.

Optional Cable

Some wireless headphones are equipped with an additional audio cable input. By purchasing this model, to save power, you can connect it to your appliances the old-fashioned way – wired.

There are other wireless connection technologies like infrared port (considered obsolete). But the most widespread are Bluetooth and Radio, therefore it best to choose among them.

Design

According to HomeCareChoices article, like traditional models, wireless headphones for the phone are internal and external. The first category includes compact devices that are inserted into the ear socket. These are more convenient because they do not hinder the user’s movements and are perfect even for sports. At the same time, they often provide lower QS and run down faster because of the reduced battery.

The outer earbuds are larger, they are overlaid on the ears and fixed with the hoop. Therefore, they are less convenient, but, at the same time, less time-consuming to work independently. The SQ of external headphones is usually better.

Offline Operation Time

One of the most important features when choosing wireless headphones is the time it can be used without recharging. So before you buy, pay attention to the number of hours of battery life indicated by the manufacturer or a shop.

With all the above-written information in mind, the longest running external headphones are those connected via Bluetooth of the latest versions. On average, they can withstand about 12-20 hours of stand-alone use.

Microphone

If you are not only going to listen to music but also want to speak via cellular communication or via the Internet, they must have a microphone in them. If you want to control what sounds will get into it, buy headphones with a movable microphone to take it aside when necessary.

External Noise Protection

Choose a model with improved soundproofing to avoid damaging the headphone experience. Vacuum-type internal headphones and closed external headphones close the ear canal tightly, so they are best to protect against external sounds.

In addition, there are models with active noise reduction. They use a microphone to monitor ambient noise and then block external sounds with the help of special technology. But headphones that support this feature are more expensive, plus the feature consumes battery power.

Audio Parameters

Let’s consider basic physical characteristics that affect the sound.

  • The frequency range determines which spectrum of sounds headphones can reproduce. The human ear recognizes sounds in the range of 20 to 20,000 Hz. Choose wireless headphones for your phone that fully cover this range if you want them to reproduce all the sounds available to the ear.
  • The sensitivity of the headphones is their volume. To keep your headphones from being too quiet, choose models with a 95dB or higher sensitivity. But don’t forget that listening to music with a volume set too high causes permanent hearing loss.
  • Resistance (impedance) affects the overall SQ and volume. For most portable devices, headphones with a resistance of 16 to 32 ohms will be the optimal choice. For home appliances, higher impedance headphones is a better fit.

Checklist for choosing wireless headphones for your phone:

  1. Choose from headphones that support the latest version of Bluetooth.
  2. If you are going to use headphones indoors, take a closer look at the models with RF transmitter: the signal will be better.
  3. The external headphones are bulkier than the internal but benefit from better SQ and longer battery life.
  4. Give preference to headphones with a frequency range of 20 to 20,000 Hz, an average resistance of 16 to 32 ohms and a sensitivity of 95 dB or higher.
  5. Choose a model with improved sound insulation to ensure that background noises do not spoil your experience.
