A multifunctional headphone with a very good sound.

  • Battery lasts a long time
  • Connection via Bluetooth and Jack plug (audio cable is included (another review states that this is not the case))
  • Sound

Because of a very good experience with Denon in my car (better than a previous car with Bose system), the choice was made quickly for this brand. After using the headphones for a while, I'm still happy with the choice!

Firstly, the sound quality of headphones is good. Nice clear sound with high tones and good bass. The headphones are easy to connect and you can easily control the audio via the buttons on the headphones themselves.

It is an ideal headset for traveling.
During a long journey, the headphones have been very pleasant. During long bus rides and flights (Max 18 hours) it has not happened that the battery was empty.

What these headphones have in contrast to many other noise cancellation headphones, is that you can connect via Bluetooth as well as via a jack plug. So you can also use your headphones in combination with an entertainment system in the plane (a double jack-plug adapter is also included, if it still exists somewhere :)). The cable can be disconnected from the headphones, so you can also enjoy your own music on your phone via Bluetooth, without having to bother with a cable on the headphones. Due to the Noise Cancellation you are completely cut off from what is happening around you. This has the advantage, for example in an airplane, that you do not have to turn the sound very loud.

The headphones come with a cover that protects the headphones well. There is a net on the outside, in which you can put your phone, for example. When I had the headphones in use and went to sleep, I could also use the cover to store my glasses and wallet.

It is therefore a handy headset that can be used in many ways, with a very good sound quality and also a good price.

Almost perfect

  • Could have a little more mid frequency

After months of research on the internet, I finally arrived at this model. I had in-ear Sennheiser headphones. The disadvantage of this is that every touch of the cable can be heard immediately. Very irritating.

I ended up dubbing between three different headphones. Most comparable price and quality. Sennheiser, Marshall or Denon headphones. All three with Bluetooth connection.
I was surprised by the enormous frequency range of these Denon headphones. In the end, this was the deciding factor for me to order this model.

The order from Coolblue, as always, arrived quickly and was well packaged. The Denon box was packed in the Coolblue packaging. It was immediately apparent from the quality of the Denon packaging that we are dealing with a quality product.
A sturdy and stylish packaging.

Once the Denon packaging had been opened, a sturdy black storage pouch was required. This included the headphones including a charging cable, a cable for wired listening, a 3.5 mm to 6.35 mm jack plug and an adapter for the airplane. All connectors have a gold-plated connection for better sound experience.

The headphones themselves feel very sturdy. A sturdy pair of headphones that uses metal fasteners. No plastic hassle to keep costs low. The further finish is good, sturdy and nicely put together. The USB charging point is even covered with a rubber cover to protect it from any moisture.

The Bluetooth connection was very fast and simple.
In my case this went via the iPhone settings to the Bluetooth setting, press the button on the headphones and pair.
Then immediately put the headphones on my head. You hardly notice you have it on. It sits so comfortably on your head. The ear cups fit perfectly over the ears. Not too big. The pillow is comfortably soft and closes everything well. The buttons are cleverly placed, you can easily reach them when you have the headphones on your head. You can also quickly figure out which button is where, without looking.

After picking a random song, I started listening. At first I was shocked by the sound. My first thought was 'is this it?' From the specified specifications, I initially expected something different.
It is a very neutral sound, with a dry bass sound and a sharp high frequency. The middle area could be a little more present in my opinion.
To give an example, I am a fan of hard rock music, in which guitars are clearly present. Drums, vocals and bass were clearly audible, but I missed the guitar power a bit.
What struck me immediately was that what I heard was extremely detailed. The different instruments were very recognizable and that without everything becoming a mess. Very handsome I must say.

The Denon app contains an equalizer. With this I hoped to boost the guitar part a bit more. Unfortunately! The app is 3 years old and never updated. Second, it is not possible to play DRM protected music such as Apple Music. That makes this app worthless to me. Then get started with the settings on the iPhone itself. Switching the equalizer from off to neutral here resulted in a slightly better sound for me.

For me, the use of the headphones is mainly intended for the train and the metro. This is where the noise canceling system comes in handy. Switching the noise canceling button on the headphones immediately ensures that unwanted sounds are filtered out.
This suddenly provides an extra sound experience. No unwanted noises from the subway or train. It really works and how.
Something extra happened when I turned on that noise canceling button. The sound itself also changed. The bass changed slightly making it a little less prominent, but still very detailed.
Probably a better sound for some and a less good sound for others. For me personally it is progress.

I've had these headphones for a week now and don't regret buying them. It's a keeper. I still hope that one day there will be an app that contains an equalizer and can play DRM music, but that will remain hope.
My only curiosity is what the sound of any Sennheiser or Marshall would have been like.

Despite the slightly less present guitar part, it is still here to stay.

Headphones with a firm 'but'

  • Good sound quality
  • Pleasant wearing comfort
  • noise canceling
  • Crack/break for no apparent reason

I bought these headphones about 5 months ago. Long doubted; it remains a solid investment.

A few weeks ago I noticed a crack on the inside that must guide the cabling.
I only use these headphones when I'm working at home, usually 2 to 3 days a week. This one never leaves my desk, never goes in a gym bag,…

After contacting the Coolblue helpdesk, I was told that this is not covered by warranty.

I'm not posting this as a reproach to Coolblue. It is indeed difficult to defend as a user that this is not due to a fall or incorrect action. However, I am sure this is not the case.

Still, I want to warn anyone considering a purchase. It is still a lot of money to break after 5 months.
