Fiil Diva Pro Headphones Review

I love that the headphone market is starting to get the attention it deserves. I see new companies that get into the game quite often in the last period.

Actually, the headphone in this review is a new project on kickstarter founded by Fiil.

Presentation and Specs


The first thing I noticed when I opened the package was a small but classy and well built carrying case. The headphones themselves seem to be very well but elegantly built. Actually, they feel and look like a premium headphone.

Let’s talk a little about the specs, technology and features that the Diva Pro has for us. You can find all the details on the kickstarter page, but I’ll go through some of them right here.

These headphones also has an internal storage of 4Gb where you can store your music and be independent of your phone or other device.

You can also control the songs and volume by swiping the outer cover of the headset.

Diva Pro can detect when you take off your headphones and pause your music. When you put the headphones back on, your music starts again.

This function is perfect for when you run into someone you know on the street or want to order your cup of coffee on the way to work since there is no need to press pause.

This is a really nice feature, especially at work where you run in the situation above quite frequently.

And here comes the Noise Cancelling feature which I really started to appreciate lately.

My AudioFiilter (MAF) is our original patented technology. With this feature, you can choose from four audio modes to maximize your listening experience. The modes include: Active Noise Canceling, Monitor, Open and Wind.

The Diva Pro has some really interesting features around Noise cancelling.

They say that the noise cancelling mode cancels 96% from the ambient noise. I didn’t measure the number but I can tell you it is quite efficient.

The monitor mode lets in some of the external sounds through the microphone so you can talk to someone but doesn’t lower your music and it does cancel some of the ambient noise.

The Open mode is quite sneaky. People think that when you wear headphones you wear them to isolate yourself from the external sounds only. Well, Open Mode does exactly the opposite. It amplifies the sounds from the environment to “hear the world or the people sitting behind you”. Sneaky, right?

The Wind mode is for reducing the noise made from the friction of the wind and your headphones.

Fiil also has a mobile app from which you can control all the features of the headphone, including the 3D effect.

FIIL Diva Pro headphones have a standby time of 40 days and playtime of 30 continuous hours on a single charge.

Listening Impressions and Tests

The tests were performed with  Aune B1, Chord Mojo, Samsung Galaxy Note 4.

These headphones also impressed me with the sound quality directly on Bluetooth mode of which I was skeptical I would like very much but it managed to surprise me in the end.

While I’ve heard some improvements coming from B1 and Mojo, the sound didn’t scale very much from Bluetooth.

The major tests were done on Bluetooth with Note 4.

Cecile Mclorin – St. Luis Gal

The voice is clean, present and very well extended and textured. The guitar manages to tickle the left ear with good sparkle and tactility. The voice is also quite intimate in addictive.

Sam Cooke – Nobody Knows the Trouble I’ve Seen

The instrument from the beginning shows good sub bass extension but also a little bleeding into the midrange. The voice is again addictive with its wonderful presence, natural tonality and extension.

Solomon Burke – Don’t Give Me Up

The guitar from the beginning is very detailed, and intimately tactile, as it really tickles the ear drum. It’s actually so intimate and tactile that it’s like you have the chords right there near the ear.

Supertramp – School

The harmonica from the beginning sounded natural and expanded nicely into space. I’ve heard more details with other headphones in this frequency range but this was natural and very well integrated into the song, having a very fluent flow. The scene with the kids was also well presented with natural ease. Actually, when the girl screamed, I got really startled, because it sounded natural and close to me. When the song starts to become more crowded the Diva Pro shows nice energy and PRAT. Overall, the song was quite enjoyable.

Otmar Liebert – Along this road

I really enjoy the guitars on Diva Pro and this song reconfirmed my findings. The guitar plucks were lively with strong plucks and good string energy / vibration, but also good extension and detail. Also there was a natural flow and tonality that made the song even more enjoyable.

AC/DC – Thunderstruck

The drums show a bass tilted frequency range and also some distortions on the sub bass. The electric guitars showed nice vibrating and lively textures and the whole song was overall energetic and pleasant to listen to.

The Diva Pro doesn’t have the most airy or big soundstage but it’s natural and the instruments are well placed inside. Actually I’ve been quite impressed by the headphones on this song. The violins were very well extended, smooth and pleasant to the ears as were the other instruments. Actually, the violins became quite addictive till the end of the song.



The bass is well extended but a little overwhelming sometimes showing a bass tilted frequency response. Also the sub bass shows distortions.


The midrange is rich, detailed and well textured. The upper midrange is however a little recessed.


The treble is a little recessed but it’s smooth, natural and very pleasant to the ears.


As expected, the soundstage is a little intimate, but it’s natural and the instruments/voices are well put into place.

Imaging & Layering

While it could use some improvements in this area, overall it managed to pull it off quite well in these departments, even when the songs got crowded.


The vocals are quite addictive on Diva Pro. The show very good presence, natural and intimate tone, good texturing and extension.


Another strong point of these headphones is the tonality, which is natural and it shows both in instruments and vocals.

Fluent/Flowing sound

The sound is also quite pleasant because of the flowing/fluent characteristic that Diva Pro gives to the sound.


If you’re just looking for sound quality, you should maybe look at other headphones in the same price range.

However, these headphones have some nice characteristics, both in sound and features that make it an interesting and useful product overall. I really dig the combination of features and sound quality of these headphones.

The noise cancelling actually works really fine, and besides that I want to mention the Open Mode feature again which is just awesome.

I tested it with my colleagues at work. It really amplifies the sounds around you and you can even hear the whispers of others.

It’s a really sneaky mode that should be called spy mode! Really cool!

If you’re interested, they’ve recently started to sell them in gearbestYou can also check out the smaller brother of Diva Pro.

  • Smooth, natural treble
  • Good imaging & layering
  • Very good voices
  • Natural Tonality
  • Fluent / Flowing sound signature
  • Good design and built quality

  • A little too much white noise on noise cancelling. This is usually noticeable in quiet environments when you don’t need noise cancelling, so it shouldn’t be a big problem.

  • Could use a little more air/bigger soundstage
  • Recessed treble
