FiiO BTR5 2021 Review

FiiO BTR5 2021

Today we’re going to be checking out the new FiiO BTR5 2021! It’s selling for $119 USD.


Disclaimer: FiiO sent us the BTR5 2021 for the purpose of this review. I only covered the import taxes and fees. All thoughts and experiences with the product are naturally my own.


FiiO is one of the most popular audiophile-focused companies in the world. They design and manufacture a wide variety of audio products for different price brackets. They have been in this industry since 2007 and they are very popular with fans all around the world. They entered the Bluetooth playground with solid products and today we are looking at their new and upgraded BTR5, the BTR5 2021. We have reviewed and awarded a lot of FiiO gear here on Headfonia over the years and you can read those reviews here: Headfonia FiiO Reviews.

FiiO BTR5 2021 Bluetooth DAC & Amplifier – What’s New?

FiiO BTR5 2021 is the upgraded version of the BTR5 that was released roughly two years ago. The previous generation BTR5 had the ESS’s 9218P DAC in dual configuration. Fiio upgraded the chips to 9219C in this new version, aiming for better performance and even lower power consumption. Both of these DACs are from the Sabre series of ESS Technology. This series offers low power consumption, high-performance DACs and they are very popular around the world so it’s easy to understand why FiiO chose this particular DAC. Additionally, the new DAC comes with MQA support. However, due to Bluetooth’s limitations, MQA is not available wirelessly. I am including the highlights of the new BTR5 2021 below.

DAC: ESS Technology ESS9219C x2 (Dual Configuration)

Bluetooth Chipset: Qualcomm CSR8675

USB Controller: XMOS XUF208

Supported Codecs: AAC / SBC / aptX / aptX LL / aptX HD / LDAC

Microphones: 2 mics with cVc 8.0 

Battery: 550 mAh / 8-9h

Dimensions & Weight: Approx. 72×32×11.1mm – 43 grams

BTR5 2021’s dedicated web page can be found here.

Let’s take a closer look at it, without further ado.

FiiO BTR5 2021

Packaging & Accessories

BTR5 2021’s package is quite interesting. The outer surface of the package is covered with a coating that gives a kind of rainbow effect. In my opinion, this package looks much more appealing than the previous package, which was simple and ordinary. 

Sliding off the cover grants you access to the foam compartment where everything is neatly packed by FiiO. The accessories are nice, you get pretty much all the essentials. FiiO provides an ABS plastic case with a clip and a small USB-A to USB-C cable to charge the device. Additionally, compared to the previous-gen, FiiO has added an elastic USB-C to USB-C interconnect cable to the package. The supplied interconnect cable is of good quality and surprisingly soft. The charging cable seems generic and the ABS plastic case does not look all that great. Fiio should have included a leather case with this beautiful product.

Design & Build Quality

Fiio’s track record on build quality has always been good. I remember Fiio’s E12-Mont Blanc portable amplifier like it was yesterday. It was a handsome device and this memory is nearly 10 years old. Look where we are now with the new Q3. Even their budget-oriented products maintain a distinct design line for years without falling below a certain quality level and I think that’s brilliant. The BTR5 2021 is no exception. The chassis of the device is made of aluminum. The front and back of the aluminum body are covered with tempered glass with a hardness of 6h. The glass is curved on the sides and it feels very nice to touch. It is also a fingerprint magnet but as always, beauty comes with a price. 

The anodized aluminum chassis of the device is covered with matte black paint and looks very aesthetically pleasing. The device features 4 buttons and they are located on the right side of the chassis. From top to bottom, we see a power button, a multi-functional button, and a volume button. The balanced and unbalanced outputs are located at the top of the chassis and the USB-C input is located on the bottom. The device features an OLED screen and it provides you with quite a bit of information about the device. You can see check the sample rate, volume level, battery level, and navigate between the menus, easily. 

FiiO BTR5 2021

The overall build quality of the device is quite nice and I think it is safe to say that it will endure physical abuse up to some extend. It is not very easy to scratch the tempered glass but it is definitely not entirely scratch-proof so I would take good care of it by not throwing it around. It is quite easy to drop the device as it features a slick surface. It is also very small and lightweight. It weighs around 43 grams and is about as big as a lighter for reference.

    I had the original and it was great.

    Did they fix the problem with the original BTR5, where it breaks the device if you use it as an external DAC plugged in to your laptop? It was still using the battery and it overcharges it. I still have my original in an unusable state, and the internet is also full of posts about this, so I’m not alone…

    • Reply November 2, 2021


      Yes, you now have the ability to turn off the auto charge feature.

      • Reply November 2, 2021


        You could turn off charging in the original BTR5 also, but it was still using the battery and turn off when depleted. This is the only way I can use it… Turning charging on when battery is low and off before it gets full. If I miss it and it gets overcharged, I have to wait a week or two until I can turn it on again. I’m so annoyed by this! An otherwise flawless product, great design, great sound, it does everything so we’ll, and then this…. I don’t know what they were thinking….

    I wonder if the Bluetooth performance is better than the original BTR5. I did have connectivity issues over LDAC when my phone was in my pocket

    • Reply November 2, 2021


      This is highly dependant on your phone, environment and such.

      The new version still uses the same chipset as the original BTR5, so no, upgrading the device will most likely not solve your problems.

    No one ever talks about the BS EQ. How it only works in wireless mode and NOT for LDAC on top of it. Its ridiculous. Even wired mode, no eq? Come onnnnn. You fail fiio

      I never use the EQ companies provide. There is a much better alternative. I use poweramp EQ app on Android, it is detailed and provides additional Bluetooth settings to meddle with. Unless we get hardware EQ, this is the best alternative.

    Hi saw this article and noticed it said the the BTR5 2021 worked with the PS5 have seen many mixed comments on this as I have been searching for an answer. Have you personally used it with the PS5 or asumed that it would work based of compatability?

    • Reply January 11, 2023


      Hello. I gifted my PS5 away but let me try to enlighten you. The PS5 works with devices that feature UAC 1.0 USB. A.k.a. USB Audio Class 1.0. It is a standard dating back over 20 years. The BTR5 can be switched to UAC1. After connecting it via USB, Go here on the PS5; Settings → Devices → Audio Devices → Output Device → USB Headphone (yes it will likely be listed as headphone).

      The PS5’s support for external DACs are messy, it can limit USB Audio output volume. So without an actual PS5, I can’t really answer your question as comprehensively as I’d like.

    Would you recommend another similar priced for wired use only?
    I like most of the features of this Fiio model (screen, size, charging or not charging battery options) but you mention there are better options for wired used.

      This is an outdated product now. You could go for BTR15 that came out in 2023. It’s a pretty solid unit and you can read its review here:

      You could also check out the E1DA 9038D6K DAC AMP.

      However, I’d stick with BTR15, as it is more versatile and feature-packed compared to others.
