Sennheiser Accentum Clip Review

Design

• Open-ear clip design
• Minimal style, available in black or cream colours
• Customisable touch controls

While still only a couple of grams, the Accentum Clip are a little heavy compared to a lot of the open-ear competition. At 6.8g per bud, they’re chunkier than most top contenders (I checked) and also a bit more front-loaded. The forward-facing part of the clip, which contains the speaker driver and capacitive touch control sensor, is a little big, and they’ve still got a sizable battery on the rear portion of the clip (that attaches to the back of your ear).

This isn’t a disaster, but it’s all worth knowing. With some adjustment, I got these feeling comfortable enough for all-day wear, but it’s not quite as simple a fit as some other cuff-style buds I’ve tried. Some of those in this category you can just pop on, and they’re light enough that you’ll barely notice them.

I also found it a bit strange to have the touch controls on the front part. Most rivals put these controls on the battery portion where they’re a bit more stable and safe from accidental touches. You’ll want to be careful you don’t pause your music while adjusting the fit of the Accentum Clip.

Thankfully, controls are fully customisable in the companion app (more on that shortly) and these have a minimal and considered look. They’re only available in black or cream, have a lightweight, pocket-friendly charging case, and a welcome IP54 dust and splash resistance rating to keep them protected.

I’ve found the fit stable when moving around and walking, too, so I’d say that once you’ve got them comfortably in place, they’re not going anywhere.

Features

I really like the Sennheiser Smart Control Plus app, and I’ve been using it a lot this year while testing out the new Momentum 5 headphones, these open buds, and the Momentum True Wireless 5, too. It’s one of the better companion apps for headphones, with a sensible layout, speedy startup and a great selection of settings and controls that feel consistent across the brand’s products.

The most appreciated one here is Sennheiser’s battery protection feature, which you toggle on to limit the maximum charge and slow the charging rate. This could make a big difference to the lifespan of your earbuds and, as I’ll explain, they’ve got more than enough juice, so limiting them to 80% charge still leaves you with plenty of playtime.

There’s also a 5-band EQ in the app and support for the high-resolution LDAC codec. In this open form factor, I didn’t find quite as much use for LDAC, and even testing back-to-back with the iPhone 17 Pro and Google Pixel 10 Pro, I couldn’t detect a difference between the codecs in use. I’d probably stick to reliable AAC, as you’ll get the most battery life that way too.

Speaking of battery life, I ran a three-hour battery drain test by playing a Spotify playlist at 50% volume from my iPhone. I saw a 40% drop in that time, indicating a total playtime of around 7.5 to 8 hours, ever so slightly under Sennheiser’s estimates but still very strong for this style of bud. It’ll likely be enough endurance for days in the office or commutes, even with battery protection turned on. Just note that the volume and codec in use affect your overall battery.

Unfortunately, I can’t get through this section without a slight downside. I didn’t really find Bluetooth multipoint worked on these. While I could connect to two devices at once, they’d rarely remember which one was the last one playing, and I sometimes found I’d play a video and there’d be no audio. These are unexpected issues in 2026, to be honest, as multipoint is a pretty widespread feature that tends to work well.

After I turned multipoint off, I also learned you can’t “pull” a connection from one known device to another; you have to manually disconnect and reconnect in the settings of each phone. These problems may be fixable via firmware, but they’re the kind of thing I notice as someone who hops between devices often.

Sound Quality

• Warm and natural sound profile
• Increasing volume can lead to distortion
• The best sound requires a good fit

Open-ear sound will always come with limitations, and the big one is that there’s just less impactful bass in an open design. And, of course, you’re going to hear a lot more of your surroundings. That’s both a pro and a con. Listening out for the doorbell to ring at home? Awareness is ideal. Trying to follow the discussion in a podcast while street traffic zooms past? It’s less helpful.

Overall, I think Sennheiser has done a great job with tuning these to be some of the best-sounding clip-on open-ears, especially at this price. They’re rich, warm and crisp, with a good sense of soundstage. It helps if you’re in ideal conditions, and don’t put the volume up too high, as that’s where I started to hear a little distortion.

In general, the sound here compares well against the pricier Bose Ultra Open Earbuds. Music feels like it has that open and natural quality that Sennheiser aims for, and there’s a lot of texture and richness in The Cave by Mumford & Sons. I felt able to hear all the instrumental elements of the mix in Gorillaz’ Feel Good Inc. and found tracks from Howard Shore’s Lord of the Rings score as spacious and immersive as I’d hope for them to be.

Fit matters a lot for sound from these buds, so take the time to get it right. They’re essentially tiny speakers positioned near your ears, so if you end up having the driver angled poorly or too far away, bass will drop off.

While you can play around with the sound using the 5-band EQ, I didn’t find it quite as helpful as it might be on other products. Any change here seems to reduce clarity, so I’d recommend leaving it on the default Neutral setting.

Should you buy it?

You prioritise sound quality over features

If you know that you need a rich and detailed sound more than a long list of smart features, Sennheiser has you covered. With the right fit, these are some of the best-sounding clip-on open-ears around, so they’re great for ambient listening with awareness of your surroundings. They’re also worth it for battery life; both on a single charge and in the long term, thanks to battery protection features.

You need multipoint and fuss-free controls

I ran into issues with this implementation of multipoint connectivity, and I had a few accidental activations of the touch controls, so I can’t give these a wholehearted recommendation based on those minor drawbacks. It takes a little adjusting to get the fit and comfort right, too, and it’s worth mentioning that there are cheaper rivals around these days.
