Comparison FiiO X5-III vs Sony NW-A35HN 16Gb

- Audio. MP3 players in the original, most traditional sense are devices designed to play music and other audio. There are models without a display, but many of the audio players are equipped with screens and can work with auxiliary file formats - like TXT for displaying song lyrics or JPG for viewing album covers or even photos. But the player in them is designed to work only with sound and does not allow video playback.

- Media player. This type includes all players that can play video. The specific characteristics of such models may vary significantly - from portable gadgets with 1.5" - 2" displays and support for specific formats to large 4 - 5" devices capable of working with unconverted files. But in any case, if you need a pocket player with the ability not only listen to music, but also watch videos - it’s worth choosing from similar models.

— Hi-Fi player. A specific type of audio player (see above), created with the expectation of maximum quality of reproduced sound. Uses high-quality components and advanced signal processing circuits; Because of this, such devices are an order of magnitude more expensive than conventional audio players, but in terms of sound quality they are comparable to stationary Hi-Fi class systems. It is almost mandatory for such models to support at least one lossless format like FLAC or A...PE; also only in such devices is it possible to work in DAC mode (see “Functions/capabilities”). In addition, the design may provide specialized interfaces - for example, balanced or optical (see “Outputs”). Thanks to all this, devices of this type can be useful both to demanding audiophiles and to those who work professionally with sound.

The operating system under which the player is running.

An operating system is not just any shell programme; this name is applied to the most advanced platforms. The OS has extensive capabilities that go far beyond the traditional functionality of the players, in addition, these capabilities can be further expanded by installing additional applications for various purposes — from online music services and media libraries to games, social network clients, etc. Thus Thus, the presence of an OS usually means that the device is a media player (see "Type"); however, not every media player has a full OS. Hi-Fi players can also have such firmware, however, the OS in them is often heavily modified, and not all such devices allow the installation of third-party applications.

Specific options for the OS can be as follows:

— Android. Operating system developed by Google, widely used by manufacturers of portable electronics; practically ousted other systems from the market, the only alternative is iOS(see below). The original Android is tightly integrated with Google services and uses the Google Play app store; however, there are many branded shells and modifications on the market, including those with rather radical changes. And you can install programs not only from the application store, but also from any other sources — by downloading the installation file to the device. The system h...as an open source code, anyone can write software for this OS, thanks to which the set of applications for Android is extremely extensive, but many of them do not differ in quality.

— iOS. Apple's proprietary operating system is not used by other manufacturers. It is closed: you can install additional applications only from the App Store proprietary storage, and for music and video you need to use the iTunes service. In addition, to create software for iOS, you need to obtain a paid license, which limits the circle of developers. On the other hand, iOS is quite convenient in that the user doesn't have to dig through an extensive set of settings; and apps in the App Store go through fairly strict quality and security controls.

The amount of built-in memory installed in the player.

This parameter directly determines how much music and other content can be stored in the device without resorting to memory cards (especially since some models do not support such cards at all). For comparison: the size of one MP3 file usually does not exceed 20 MB, the same composition in lossless format has 3-4 times more volume, a film in standard quality takes on average from 700 MB to 2.5 GB, in HD 720p — up to 5 – 6 GB. Thus, in terms of data storage, the more internal memory, the better. On the other hand, the price of the player directly depends on the storage capacity. Thus, some models are available in several modifications, differing in the amount of memory and price.

When choosing, note that part of the memory will inevitably be occupied by software firmware and pre-installed applications; sometimes this part turns out to be quite significant — for example, in models with an OS on board (see above), several gigabytes can be occupied. Also note that memory cards in terms of gigabytes of volume are cheaper than built-in drives, and from the practical point of view, in most cases they are not inferior to them. So it makes sense to specifically look for a player with a large amount of internal memory, first of all, if this model does not work with memory cards.

Now there are players on the market with such a memory capacity: up to 8 GB, 16 GB, 32 GB, 64 GB and more. However, there are also models without built-in memory, designed for use only with memory cards.

Type of memory cards supported by the player.

Memory cards perform two main functions. First of all, they increase the total amount of the player's memory; at the same time, such memory in terms of gigabytes is much cheaper than built-in drives. Secondly, a memory card allows you to exchange data with another device that has a card reader; for example, it can be used to copy music to the player from a laptop.

Modern players usually use SD or microSD cards of one version or another. SD cards have dimensions of 32x24 mm and are used in relatively large devices, miniature microSD (15x11 mm), respectively, in compact models. Versions can be:

— SD. This marking means that the device is capable of working with at least original SD cards (not related to later versions of SDHC or SDXC). Such cards can have up to 4 GB capacity, their capabilities are quite enough for most tasks related to content playback.

— SD/SDHC. Models compatible with both the original SD (see above) and the newer SDHC format. This format allows you to create removable media up to 32 GB.

— SD/SDHC/SDXC. Support for all major SD formats used today. About SD and SDHC, see above, and SDXC provides card capacity up to 2 TB and increased speed.

— microSD. Players guaranteed to work with original microSD cards. Technically, such cards are similar to the SD cards described above and differ from them only in size. At the s...ame time, it is worth noting that a device with such a marking may actually be compatible with more advanced media (like microSDHC or even microSDXC), just the manufacturer, for one reason or another, did not go into such details. You can clarify this point by evaluating the maximum supported card volume (see below)

— microSD/SDHC Players that support both the original microSD and the later microSDHC standard (see "SD/SDHC").

— microSD/SDHC/SDXC. Players with this marking are compatible with all modern versions of microSD cards — both the newest microSDXC (see "SD / SDHC / SDXC"), and previous standards (see above for them).

Players are produced that have two slots for memory cards at once — usually microSD. Basically, these are Hi-Fi devices (see "Type"), and this feature is provided for an additional increase in available memory volumes: Hi-Fi content has a significant amount and requires appropriate storage.

The maximum size of the memory card that can be used in the player. This parameter is directly related to the card type (see above): each type has its own volume limits. At the same time, the ability to work with capacious media is limited not only by the type of card, but also by the player's hardware. Therefore, many models have a lower capacity limit than the memory card suggests — for example, 128 GB in a model that supports the SDXC format (the theoretical maximum for which is 2 TB).

Note that the reverse situation also occurs — for example, when a device with a maximum capacity of 16 GB only supports microSD cards (theoretical maximum is 4 GB). This usually means that the player can work with newer formats (in our example, at least microSDHC), but for some reason this point is not mentioned in the official specifications (for example, the manufacturer could make a mistake in the documentation).

Model of the digital-to-analogue converter installed in the device.

The DAC is one of the key components of any player: it converts the digital data recorded in the audio file into an analogue audio signal, which is fed through an amplifier to the headphones. The quality of the DAC directly affects how accurately the output sound will match the original signal, as well as whether the player can work with advanced digital signal formats: many of them require high computing power, which is not available in every DAC.

Note that the DAC model is indicated only if it is a high-end converter with above-average sound quality. On the modern market, in particular, DACs from such manufacturers are represented: AKM, Cirrus Logic, ESS Saber, Texas Instruments, Wolfson. And players with such equipment usually refer to Hi-Fi devices(see "Type").

It is also worth mentioning that the number of DACs can be different. The simplest option is one module for both sound channels, however, there are players equipped with two converters at once — one per channel. This "division of labor" affects the cost, but reduces the load on each individual DAC, which has a positive effect on the quality and reliability of the sound.

The range of audio frequencies that the player is capable of reproducing. The wider this range — the more complete the picture of the sound, the less likely that the device will "cut off" part of the sound spectrum. At the same time, when choosing this parameter, several points should be taken into account.

First, the average human ear is capable of hearing sounds from approximately 16 Hz to 20 kHz; deviations from these figures are small, and with age the range narrows even more. In fact, this means that for normal hearing, it is enough just to cover this gap. And the wider boundaries indicated in the characteristics of the player will be more of a marketing ploy than a really significant moment. Secondly, do not forget that the sound quality is determined not only by the range, but also by a number of other characteristics of the player — signal-to-noise ratio, frequency response, etc.; therefore, a wide range by itself does not guarantee a pleasing sound. And thirdly, the features of the audible sound also largely depend on the headphones used and their frequency range: all the advantages of a player with a wide frequency range can come to naught if the frequencies are “cut off” by the headphones.

The ratio between the level of the useful signal (clear sound) and extraneous noise, given by the player at the output. This parameter directly characterizes the quality of the built-in amplifier: it mainly takes into account the intrinsic noise of electronic circuits, and the higher the signal-to-noise ratio, the less these noises and the clearer the sound.

Note that in the case of players, this characteristic is often not particularly critical: the noise of the amplifier can be lost against the background of ambient sounds, especially in an urban environment, and for such situations even the most modest indicators, at the level of 70 – 80 dB, are enough. At the same time, for Hi-Fi models (see "Type") this moment is one of the most important; in the most advanced devices, the signal-to-noise ratio can exceed 120 dB.

The higher the power, the louder the sound you can get on the headphones, all other things being equal. In addition, higher power allows you to connect "ears" with higher impedance to the device (although there is no hard correlation here, and models with the same output power may have different headphone impedance limits). However, in the case of ordinary (non-Hi-Fi) players, this parameter is more of a reference than practically significant: usually, the power of the amplifier in such models is quite enough to “rock” most consumer-grade headphones. But for Hi-Fi devices (see "Type") models, output power is of key importance: it determines compatibility with high-resistance studio-class "ears".
