Best Ways To Play FLAC Audio on an iPhone

Free Lossless Audio Codec (FLAC) audio files contain high-resolution audio, designed to capture every detail of the original sound. They are known as lossless files, and can only be played by certain compatible FLAC players. 

Lossy files, like MP3s, are smaller files and take up less storage space, but also contain fewer sound data and offer a less granular representation of the original sound.

Unfortunately, iPhone’s native music apps do not support FLAC file types. If you’re going to listen to FLAC audio files on an iPhone, you’ll need a special app meant to play FLAC files, along with an external digital-to-analog converter and a high-quality set of headphones. 

Without the external equipment, you’ll lose out on sound quality in the transmission process even with a great player.

We talk more about what kind of equipment is needed and recommend products at the end of this article.

Audio quality can also be lost in the process of transmitting audio over Bluetooth, so having wired headphones is important for listening on an iPhone. 

What Makes a Good FLAC Audio Player

A good FLAC audio player has an easy-to-use interface and has equalization settings for personalized listening. A special key feature is the conservation of original file quality.

Some audio players downsample high-resolution audio to CD quality, which is not ideal. The best FLAC audio players also have metadata support.

Top FLAC Audio Players for iPhone

Most audio players for the iPhone don’t support FLAC file formats, so the audio quality is typically limited on a smartphone.

However, there are many apps available that allow you to play FLAC audio files, and some are particularly easy to use and of high quality.

Can You Use Native iPhone Apps To Play FLAC files?

There is a way to play lossless files with your native music app on an iPhone, but only Apple Lossless Audio Files (ALAC) is supported, not FLAC. This requires you to convert your files, but the file formats are nearly identical and offer the same audio quality. 

You can convert FLAC files to ALAC with a number of different file conversion apps, as discussed below.


DBPowerAmp can perform many kinds of file conversions, including conversions on batches of files at a time. It also allows for the addition of effects, like volume level and normalization.

The software can be tried for free for three weeks, and then is a bit pricey. 

But, it will allow you to convert your FLAC files to lossless files supported by the native iPhone music app.

MediaHuman Audio Converter is completely free to use and allows you to convert FLAC files to ALAC without any loss in audio quality. Just make sure that you use the custom settings to set your files to hi-res, which is not the default setting. 

After converting, these files can be moved to iTunes, but again, watch your settings to make sure you don’t lose audio quality in the transfer.

Why You Need an External DAC To Play Hi-Res Music on an iPhone

A digital-to-analog converter (DAC) converts a digital audio signal to one that can be played over a pair of headphones or speakers, and plays a big role in the sound quality you hear. DAC chips are located in your iPhone or other music-playing devices, but also exist as standalone external devices.

A bad DAC can introduce noise to the audio playback, or poorly regulate the supply of power. You may notice distortion when listening to music on your iPhone, even if you have a FLAC player and FLAC files to play. 

A good DAC, however, can make all the difference to your sound quality. Let’s take a look at some of the better converters.

AudioQuest DragonFly USB DAC/Amp

The DragonFly-series from AudioQuest is our favorite DACs for portable use. They are fantastic!

The AudioQuest Dragonfly is very compact and portable, making it perfect to use with a phone or a laptop. It comes with a 3.5 mm (0.14 in) jack and a micro USB connector.

The red version of DragonFly is usually the best option for beginners not knowing what they need. It has a 2.1v output and is therefore capable of driving almost any headphones, even the more power-hungry, low-efficiency models.

But there is a cheaper model, the Black, that is very affordable but also less powerful. It works great for more easily driven headphones though.

This DAC has LEDs that light up in different colors according to the size of the files being played: green for 44.1kHz, blue for 48kHz, amber for 88.2kHz, and magenta for 96kHz.

To use this DAC with an iPhone, you will have to use an adaptor. The best option is to buy Apples Lightning to USB Camera adapter to be able to connect the DragonFly to your iPhone.

That will not have any negative impact on the audio quality or the function of the DAC. It will make the setup a little less portable but it is usually fine.

Chord Mojo Headphone Amplifier

Chord Mojo Headphone Amplifier offers an impressive upsampling rate limit of 768 kHz, using the latest and most powerful processors. It comes with three ball-like buttons that control volume and power, and the power button lights up in different colors depending on the sampling rate of the music (red for 44.1kHz, green for 96kHz, and white for DSD). 

The Chord Mojo comes with a USB port and a 3.5 mm (0.14 in) jack, with a second USB connection just for charging. With an output of 35 megawatts at 600 ohms and up to 720 megawatts at 8 ohms, it is enough to power a solid level of volume from a range of headphones.

This DAC is made of aircraft-grade aluminum and comes only in black. It needs a minimum of 10 hours of charging and can hold a charge for about 8 hours total. While it runs hot while charging, that doesn’t interfere with the function.

Watch the video below for more information on the Chord Mojo:

Cyrus SoundKey

The Cyrus soundKey DAC is a compact, portable DAC that offers great quality for the price. It weighs 18 g (0.63 oz) and is 8 mm (0.31 in) deep, and made of a lightweight aluminum casing. 

It comes in red, purple, black and turquoise, and has a 3.5 mm (0.14 in) socket for plugging in headphones or a sound system. 

Just like most other DAC/Amp combos, The Cyrus soundKey, requires a dongle adapter to connect to an iPhone. The small size makes it portable enough anyways and the quality is worth it.

It can handle a wide range of file types, including FLAC, and conserves resolutions up to 24-bit/96kHz. 

Conserving FLAC Audio Quality on an iPhone With High-Quality Headphones or Speakers

Once you have your FLAC player and high-resolution music to listen to, you need to make sure that every other piece of your audio system in place maintains the same standard of audio quality.

The weak link in your chain of audio equipment will always deteriorate the sound to its maximum quality level, which is something to be aware of before you make any investments.

Open-backed headphones are an excellent choice for those listening to high-resolution audio at home in a quiet environment. It offers open acoustics and usually a better soundstage.

An example of a great pair of headphones with an open design is the HIFIMAN HE400SE, built for hi-res listening.

Closed-back headphones can also be great, though, especially on the go. Check out these, for example!

You can also find hi-res earbuds, like the FiiO Hi-Res Earbuds available on, which provide a more isolated sound and are better if you’re looking to listen in a noisy or crowded area. 

If you’re looking for a hi-res-compatible active speaker, make sure you find one that offers a balanced sound at different frequencies, like the KEF LSX. These popular high-end wireless speakers offer a four-inch driver and Wi-Fi connectivity for minimal data loss.


The 11 best FLAC audio players for iPhone include Vox Media Player, Onkyo HF Player, and TEAC HR Audio Player. All of these and more support FLAC file types, and have a user interface that gives you easy, full control over your music. 

For the highest possible resolution, make sure that you’re also using high-quality headphones or speakers, and a solid DAC.
