With its open design, the Philips Fidelio X1 delivers exceptional sound performance combined with superb design. It is recommended!

Summary 8.3 Excellent


  • Pros: The Philips Fidelio X1 is an open headphone with a very nice design and excellent comfort. But it does not stop there and offers impressive sound quality, with particularly well-defined bass. The cable is detachable.
  • Cons: Relatively expensive. We also regret the absence of a protective case for storage and transport even if it is primarily intended for sedentary use.
  • In Short: With the X1, Philips completes its range and offers an open Hi-Fi headphones rivaling the best products on the market. A bet not easy but won for the builder.

Philips Fidelio X1 Review

The X1 is the most upmarket pair on the Fidelio line of Philips, already known for offering products with more than correct sound performance.Unlike the Philips Fidelio L1 and Philips Fidelio M1 models, this model is an open circum-aural helmet, for those looking for equipment primarily for home use and not nomadic like its two younger brothers.

This kind of open headphones generally offers the best audio quality, with a well-ventilated sound and a rare quality, and Philips launches here on a terrain dominated by major players in the world of audio. In direct competition with a Sennheiser HD 650 for example, the X1 is a real surprise and Philips offers here an excellent product completing a now complete range.

Design and comfort

As a general rule, open headphones are not especially deemed to be specially designed, which is understandable given their primary purpose: stay at home. If the look of this X1 is clearly different from what can be found in the mobile models M1 and L1, it is nevertheless very nice. I love this light retro side with these large velvet headphones and its arch covered in real leather. Clearly, the Philips model is far more beautiful than an HD 650 or a Shure SRH1440 and no one will complain. The whole thing looks very solid and robust, with quality materials that should allow the X1 to last in time.

On the level of comfort itself, the most important thing is the padding of the headphones and that of the inner headband (the part that rests on your head). These two elements directly affect the comfort of a product and will make the difference between a noise canceling headphone that is forgotten and one that you will not be able to wear more than 30 minutes.

The Philips Fidelio X1 passes the test with brilliance, including a two-piece arch. The first in leather ensures the overall hold of the helmet, and a second under wider and padded distribution distributing the weight of the helmet over the width of your head. It automatically adjusts to the shape of your head and is a real pleasure in practice.

The headphones are not left out, with a generous padding covered with a very comfortable black velvet. Be careful however during the heyday, it can quickly get hot. That said, you should not really suffer from sweating with this helmet, especially thanks to its open design.

Indeed, the X1 is therefore thought to be used in your home and using it outside will make you quickly understand why. The metallized grids on the two headphones allow very easy entry and exit of the sound and therefore isolate very little.

Accessories and Cables

If most manufacturers often offer a full package of accessories and cables with their headphones or earphones, Philips is a bit stingy on this one. It is believed that by its use, Philips believes that these are optional.

No carrying case so in the box, but only an adapter 6.3mm to 3.5mm jack. Of course, as often with this type of product, the main cable is a 6.3mm that can simply plug into your Hi-Fi channel for example. This one is sturdy and should hold the length. Its length is approximately 3 meters, which is usually enough to use at home.

Sound quality

Inside the Philips Fidelio X1, there are 50mm neodymium speakers. Extremely wide models, therefore, superior to the 40mm of a Sennheiser HD 700 but not at the size of the 56mm drivers of the Sennheiser HD 800 (a real monster).

But the size of the speakers does not do everything and some produce offer disappointing performances even integrating them. Fortunately, it’s long to be the case with the Philips Hi-Fi X1 headphones and it is a real pleasure to enjoy the open and airy sound it offers.

The responses in the different frequencies are really very good, offering a particularly natural sound, with deep bass but far from exaggerated. Basses precisely very well dosed and positioned that provide listening pleasure, rare to be able to enjoy them on an open helmet. Compared to the L1, the sound is better proportioned and it is felt quickly listening.

The mediums are equally effective, very consistent and offering vocals close to perfection. Not much to say about the treble either, which are clean and detailed but never aggressive ears.

I say it all the same, but if you want to opt for an open headphone like the X1, consider always using sounds with very low compression in order to avoid the losses and take full advantage of the potential of such a product.


The Philips Fidelio X1 is clearly one of the best open Bluetooth headphones on the market today. With a neat and elegant design, a formidable comfort and very good sound performance, we can only recommend it. If you have the budget you can darken your eyes closed, sedentary audio headphone level, Philips demonstrates that it also knows how to do it.
