The Sennheiser Accentum Open earbuds feel light. I hardly feel them in my ear. I think the music sounds clear and balanced. The material of the earbuds and case feels a bit fragile.
Easy connection I can easily connect the earbuds to my phone. I put the earbuds in the charger and open the Bluetooth settings on my phone. They automatically appear in the menu. Then I click on them and the earbuds are connected. I find it convenient that I don't need an app, as I do with other earbuds or headphones.
Clear sound I think the sound is clear when I listen to music. I can clearly hear vocal voices and the background music sounds clear. I find the bass tones solid, which allows me to hear the beat well with rap or techno. This allows me to get lost in the music. With a podcast I can clearly hear voices. However, the sound here sounds a bit thinner and further away. It therefore sounds a bit less realistic.
Compact design The case and the earbuds are compact. The earbuds do not stick out and have a short stick. I find this handy, because my hair does not get caught on them easily. My earring also does not bump into the earbud easily. The case fits easily in my trouser pocket and does not feel heavy. The material of the case does feel a bit fragile, I think.
Open design I would not say that the design is open, because the earbud goes in my ear. I do hear a lot of my surroundings, which is characteristic of an open design. When I turn up the music, I hear conversations in the office, but I do not hear what is being said. When I do want this, I turn the volume down a bit. Now I can hear what is happening around me well. On public transport, the conductor's voice sounds clear.

I was allowed to test this product and was immediately pleasantly surprised by the look. Beautiful sleek case and beautiful neutral color. The sound quality did not disappoint either. Exactly what you are used to from Sennheiser products and the lack of the noise canceling option does not detract from the quality. The battery also lasts a long time, I have used them quite a lot every day for a few hours and only had to charge them after a week. In addition, it is very nice that you can connect them to many devices, which makes it very easy to use. The only downside for me personally is that they are just a little too big for my ears, which means that they slowly fall out of my ear when talking, chewing and moving a lot. When I sit still, I have less trouble with this. Still, they fit better than all the 'in-ear' earphones I have tried.

I had the privilege of testing these earphones, which came at the perfect time for me as I recently lost my previous earphones. My first impression is good, it is neatly packaged and the instructions for first use are easy to read. The steps to use the earphones for the first time are simple and require little effort. The earphones are also immediately in pairing mode after briefly putting them in the charger for activation. This makes connecting to your smartphone seamless. Once paired, you will receive a tone to confirm that they are connected. Furthermore, the earphones fit perfectly in your ear. However, it is a large earphone, which means that with a narrow ear canal I sometimes have to search for a comfortable position. Only for a longer period of time it can be less comfortable if you have a narrow ear canal. The sound in it, on the other hand, is great. Nice and full and no dominance of the low tones but a nice balance. What you are used to from Sennheiser. I charged the case no less than 2 times during the test period. And there is no worry about an empty battery at all.
All in all good earphones for the money! And for anyone who can't get earphones with a silicone tip in, highly recommended.
