The development of wireless devices and components has long since become ubiquitous. The new releases and the sales figures speak a clear language. Until a few years ago, if you were considering whether to buy with or without cables, you now have another choice: wireless or Bluetooth headphones?

If your headphones are not working properly, just contact our headphone specialists . Our technicians have many years of experience in the field of headphone repair.

Why Wireless?

The dominant argument in this question is: Mobility! Detached from the annoying "cable salad", this includes both the musical experience in one's own four walls, as well as during sporting activities. Whether this is in any case due to the particular desire for individual irrigation or the consideration of others, we leave out at this point.

Despite more or less crucial differences, there are some common features in both headphone systems:

Battery: Headphones are electronic devices that need to be powered. Since a cable is not available, batteries take over this task. Depending on the price range and equipment vary the use and loading times. Please do not necessarily rely on the relevant manufacturer's specifications for your purchase interest. A look at relevant Internet forums does not hurt at this point.

Components: Whether wireless or Bluetooth headphones, both require a transmitter and a receiver as a radio link for data exchange.

Radio transmission: The data are transmitted in both systems in the form of electromagnetic waves. The waves in turn are more or less susceptible to environmental influences in their properties. These include structural conditions and other electromagnetic radiation.

Differences

Comparing both systems with some features can help you choose the right equipment for you.

Range:

The range depends on many factors. Therefore, pay attention to the manufacturer's information when buying. It is important that the headphones match the capabilities of the transmitter. For Bluetooth devices, there is a division into three classes, in which the distances are specified. But even these can only vaguely consider the influence of walls and furniture. These things reduce the possible distance between transmitter and receiver for radio and Bluetooth headphones, the susceptibility of the former is particularly high. If pipelines or similar are present in the walls, this also reduces the range of wireless headphones, while this does not affect transmission via Bluetooth.

As a guideline, the following values can be assumed:

  • Bluetooth: about 10 meters (some devices up to 100 meters)
  • Analog radio headphones: 150 meters
  • Digital wireless headphones: 100 meters

Noise:

For radio headphones, the signal is transmitted in the MHz range. Especially in the analog method , the negative influence of other radiation is more common. In addition to a continuous noise floor significant errors are not uncommon, ranging from a popping and crackling occasionally to demolition. Because the interference comes from the outside, the headphones in another household can work wonderfully.

In digital radio transmission , the signals are processed in advance. Faults are detected and, so to speak, "not included". The disturbing influence of environmental influences is reduced, but he just does not disappear completely.

Bluetooth uses a frequency band in the GHz range, which is divided into numerous channels. The transmission between the channels changes up to 1600 times per second in order to transmit the signals as "cleanly" as possible. This is not possible to 100% and it is quite possible disturbances that express, albeit less frequently, in the termination of the compound.

Charging times Battery:

At this point, the Bluetooth devices are clearly ahead. While the in-ear models require 2 hours due to their smaller size, the batteries of the on-ear headphones are charged after about 4 hours. The differences in the time of use are correspondingly similar, with the on-ear devices with about 20 hours clearly surpassing the smaller devices with 8 hours.

The average battery charging time is given for wireless headphones with 8 hours. In some forums, indications of up to 15 hours appear, although here probably only the initial charge may be meant. Otherwise, I think a technical review is advisable. With a usage time of 20 hours, these devices are also fully in the limit.

Sound:

Whether wireless or Bluetooth headphones, both have one thing in common with regard to the sound: there is a direct correlation between price and sound quality. The more expensive a headset is, the greater its tonal possibilities. In addition, especially with Bluetooth devices, two aspects determine this feature. The smaller design limits the use of sound elements in in-ear devices, since the space for battery and security elements is needed. Since the signals are transmitted compressed, this limits the sound quality. If this deficiency should be eliminated, this is reflected in the price.

Because of the lack of compression, the sound is generally better with wireless headphones . It looks more natural and has better surround sound properties. Nevertheless, it also applies here that a reduction in the design means sacrificing the sound.

Price:

The price has a direct relationship to the equipment of the devices. Although not always, a higher price usually means better quality. Who makes his purchase decision, especially with the "second devices" for the Smartphone, depending on the price, must not complain with defects in the sound quality.

Which One is Right For Me?

With a clear conscience, one can say that the (!) Headphones do not exist. Rather, here too applies that in addition to the purse, the need is crucial. In addition to your own requirements, these include the occasions when you want to use the headphones. For example, if you would like to enjoy very good music but are also active in sports, you should prefer to use two varieties.

If you can not answer the question radio or Bluetooth headphones in the end, still remains the wired variant as an alternative.

Here eliminates the disturbing influences from the outside as well as the required battery. In addition, these devices score with a better sound, which you also get for a lower price.
