These earbuds fit really well and sound amazing…!!!
What I like: - The ear-fins do make a big difference in terms of fit… these earbuds fit securely inside my ear and I don’t have to constantly push them back in. - The case quality is not as good as that of AirPods but it’s a functional design, and the included lanyard makes it easier to find the case inside a bag. - The Sennheiser sound signature is unparalleled. - I like the implementation of focus and aware modes. There is a very perceptible difference in the two modes and I really like the bass boosted sound signature of aware mode, it makes the sound very lively and energetic. What I don’t like: - These earbuds do come with a transparency mode, but it only gets activated while making a call or using Siri, otherwise you cannot activate it… this does not make any sense. If Sennheiser added the hardware that enables transparency mode, why not let us use it? - In the app it only gives one battery percentage but I don’t know whether that is the case battery percentage or the earbuds battery percentage. It’s a bit confusing. Overall: I like these earbuds a lot and I’m happy with the purchase.

The product life us short.
One ear bud stopped working after 7 months. No support from Amazon or Seller. Loss of money on a high price product.

Frustrating experience from start to finish!
I really wanted to like these earbuds, but my experience has been nothing but disappointing. Right out of the box I had constant connectivity problems – sometimes the left earbud wouldn’t connect, sometimes the right, and it was a hassle every single time I tried to use them. Since the product was under warranty, I sent them to the Service Center and got a replacement. Unfortunately, the replacement had the exact same issue. Sent those back too, and only on the third try did I get a pair that worked “okay,” though even then there were still small glitches. Fast forward to now – my 2-year warranty expired in January 2025, and wouldn’t you know it, the right earbud has completely stopped connecting. I’ve tried every reset and fix suggested online, nothing works. So after two years of back and forth with service centers and multiple replacements, I’m left with a useless earbud set. For the price, I expected way more reliability and support. Once the warranty is over, you’re basically out of luck. Save yourself the frustration and look elsewhere.

Sounds like Sennheiser momentum.
I was using Sennheiser momentum wireless neckband for like last 4 years before that I had the wired momentums for 5 years or so. Hence, I am not new to Sennheiser sound. Sound quality- Even though this are not momentums, it sounds exactly like my old momentum wireless neckband with that characteristic Sennheiser sound with good bass, articulate treble and yada yada. It stays in ear fit and secure , but it is not good for long use. My ear pinna was in pain after an hour of use. Good for exercise or Yoga and such rigorous routine which take only an hour or two, but for long listening in train or travel I will use my neckband earphones. I bought this for listening to music during my Yoga sessions, so perfect for me.

Claiming warranty issue
sennheiser no longer support their products, seems like they sold it to some other company which only have service centre in Delhi. So if any complaint you need to courier the product to Delhi. Unless you are located nearby Delhi inwouodnt recommend Sennheiser products. I been struggling to handle calls without headset for a while (delay in round-trip..etc

Perfect for short use.
I’m very happy with the sound quality and Bluetooth connection stability, and often use it paired with my watch for runs. They aren’t too comfortable for long use but that’s not really the intended use case. Highly recommend as a water resistant good quality pair.

Excellent earbuds for running and cardio !
Have been using them with other earbuds and neckbands. Love these. Great app. Stable connection with all Samsung devices including Galaxy Watch. Equalizer needs customization before it gives a great sound quality. But it does match the best in sport earbuds. A great battery life is an added advantage. Grip on the ear is great but requires a trial of different wings among those provided. Overall, highly recommended !

Bery Good For Gym purpose, But Not Best
Good Grip in your Ear for Athletic workouts. Sound quality is more like natural, but was expecting little better. I don’t use it for other than workout so battery back up - no comet's. It’s fine for me. Calls are fine no problem. I just receive. Grip to the ear is better with JBL Edurance dive, but inferior sound quality. Ear aches in both a but, less with Sennheiser. While workout, I don’t even feel it.
