Review: Crisp, Well-Balanced Audio - Inside the outer packaging, the earbuds come in their own product box and are adequately protected from damage during transit. The box contains the earbuds, the charging case, a charging cable (no plug top) and product documentation. The Quick Start guide is enough to get started but the User Guide is a must have. You can Google the pdf or get it from Sennheiser’s website. With desertcart’s Open Box Inspection service, you can check the product for damage and confirm that all accessories are present at the time of delivery. It is important to note that open box inspection does not include actual testing of the earbuds to confirm if they are working. For my order, the product was non-returnable, with replacement available only through a service center. Since my earbuds are working, I cannot provide any feedback on the replacement process. The earbuds are made of polycarbonate and the look and feel are somewhat less than premium. However, this is not an issue for me because I purchased the earbuds for sound quality and not for the way they look. The build quality is sturdy and can withstand being dropped or sat on, both of which I have accidentally done. These earbuds fall in the mid-range price category and I think they offer very good audio quality for their price. The clarity and range of the earbuds are excellent; also the audio is very well balanced with lows, mids and highs being equally audible. If you want your earbuds to deliver thumping bass which drowns out the other frequencies then these earbuds are not for you. These are open earbuds so they fit differently from in ear style earbuds, i.e. they sit at the entrance to the ear canal and are not pushed inside it. Naturally, they sound different too. If you’re using open earbuds for the first time, be assured that it is sounding the way it is meant to. The earbuds have not run out of charge yet so I cannot comment about battery life or charging speed. I’ll update the review when I have more information. The ACCENTUM Open does not have an app. This means you do not have an equaliser and cannot customise the touch controls. You will also not receive firmware updates. My previous headphones did not have touch functions so it’s taking me a little time to get used to this feature. However, the controls are intuitive and I’m sure I will become comfortable with it in a few days. As an aside, I can listen to music while lying on my back, but not on my side; the pillow accidentally activates the touch control. All in all, a very decent pair of earbuds. I love the crisp, well-balanced audio, comfortable fit and fast charging. I only wish they came with the Sennheiser app. I would highly recommend the ACCENTUM Open to anyone looking for a pair of open earbuds.
Review: Quality and satisfaction - It's so poor quality product. Not connects to any official app of the brand. So painful for ears. I switched from JBL open TWS which was less costly and unbeatable quality with dedicated app to manage advanced features. I am going to sue for misguided information given by desertcart for this product. Poor call quality. Battery is ok. Design is unappealing and not handy. Go for JBL wave 2 flex for better experience.

### ⭐⭐⭐⭐⭐ Fun, Comfortable, and Good Sound.
*by E***A on 1 August 2026*

Just got my hands on the Accentum Open buds. The buds are really good, sound is very nice and loud enough. There are a lot of negative reviews of late talking about fit and ANC, what not. Please read the product details first. These are open buds, it's a different category altogether than the in ear style earbuds. You cannot put any type of noise cancelation in open type earbuds and sound will come from far and also bound to be perceived less because they sit at the outer part of ear canal and not stuffed in. The sound is really good, felt that bass, mids, and treble are all balanced and earbuds are loud enough. I do feel that build quality could've been better because as is it feels all plastic. Controls are simple and intuitive, connects easily to the phone, fits well in my ear. I've used Razor's gaming open type earbuds and loved them and since then have been looking for something similar. These Accentum Open does that for me.
