Description

Audio technologies have improved a lot in recent years and the Chinese giant Xiaomi (many times in collaboration with 1More) was not going to miss that train. We have many models of headphones and helmets, so here we are only going to characterize the large groups in a general way and in the table it can be easily compared between them, to end up choosing the one that best suits the needs of each one.

There are two main types of headphones: headband and in-ear (or intra-ear). Both are very easily identifiable and, in general, there is a rather large price difference between them, the headband being more expensive. This is a general rule only given that there are more expensive in-ear headphones than some with headbands taking into account the different ranges.

A highlight among headband headphones is that they are generally more comfortable. For long train, plane or bus trips in general, they are more recommended than the smallest ones, although their weight is also higher. Normally their autonomy is sufficient for these trips of several hours, the recommendation, in this case, would be that we acquire some with, at least 20 or 24 hours of autonomy at a medium volume. The capacity of the battery is not very relevant in this case because the technology of the drivers and the software of the device itself can be very different between devices with the same amperage, even within the same brand.

Another feature that they usually incorporate is noise cancellation, this can be passive or active. Passive cancellation is one that does not require software to be carried out and does not depend on the external environment. The isolation is produced by the same construction and placement of the device. On the other hand, if the device has active noise cancellation, this will be activated or deactivated normally by means of a switch. These devices incorporate at least one microphone only to detect external noise and cancel it via software so that we only hear the sound emitted by the headphones.

On the other hand, they incorporate microphones to be able to interact with intelligent assistants or answer voice calls. Connectivity is carried out via Bluetooth, although in some cases they can incorporate an NFC chip. It goes without saying that a wired device does not have connectivity technologies, but it can have noise cancellation. The way to charge this type of headphones, when they are wireless, is through a Micro USB or USB Type-C port (the latter is recommended for being the most modern option, in addition to the reversibility, which directly affects the comfort of use of the port).

If we now look at the ear canal headphones (or in-ear) we see that are much lighter, but for some people, it may be uncomfortable to enter the ear canal headset. It is less common for them to have active noise cancellation, although passive noise can be quite effective. Their battery is usually shorter, in the case that they are wireless, and they are usually more oriented to the sports field. For this reason, it is highly recommended to purchase ones that have an IP type certification. At least IPX4 for a device with these characteristics.
