Review: Excellent all round, highly recommended. - I purchased these over a year ago after going through a phase of using cheaper brands of earbuds, which all became faulty pretty quickly, I splurged on these and they are really excellent. The stability of the fit is superb thanks to the innovative little fin at the top. The sound quality is very good, not audiophile but nearly there, not too bassy. Excellent all round, highly recommended.
Review: Could be my Best Headphones so Far? 🏆🏆🏆 - Ive had so many headphones over the years. Ive always looked for "Good Sound" and durable. The 1st thing i noticed was the "Frequency Response". These Bad Boys go 5Hz to 20000Hz which i think is rare. On my search for headphones it seems most headphones only go as low as 40Hz, with other brands, which is "OK", but for real bass heads you want that boom in your headphones look no further. They are comfortable once you find the Fitting for your ears. they didnt hurt and i could wear them for Hours. Ive also seen people say "Its Not Loud enough". IMO the level is fine. its loud enough to hear all the detail in the music u are listing too without distortion. It also comes with a really good durable case. Battery is great too. Ive seen mixed reviews but i gotta say Senheiser for QUALITY, GOOD PRICE have a real good product here. If ur a Jogger, Gym head, Walker, traveler i think u will like these. Good Purchase, u wont be disappointed 🏆🏆🏆 👌

## Questions & Answers

**Q: Will they work wth MP3 players? I don't want to use them with my phone.**
A: They’ll work with anything with Bluetooth.

**Q: Do they remain paired with 2 different devices at the same time? Or do you have to unpair and then paor with the other ie to answer a phone call**
A: No don't stay paired 2 to different devices at once

**Q: How secure are these in ear when running? I have owned many earbuds & the only ones that have properly stayed in have been Jaybirds. Are these secure?**
A: Personally I don’t rate them very highly at all. They are not that secure and within a week one stopped working . The Bose sport earbuds are better sounding and they are more secure. That’s just my opinion though

**Q: Whats the sound quality like?**
A: I've had these true wireless earbuds for about a week so far and the audio quality seems great so far, they have the usual audio quality you would expect from Sennheiser products.
So far I have only tried them with the alert buds which are great for running so you can hear cyclist bells and encroaching cars (some damping even in this mode as your own footfall isnt audible). I'll add a full review once I try the focus buds to see how good the sound cancellation is.

### ⭐ Left earbud breaks after 4 months
*by M***R on 14 March 2025*

Don't bother buying these. I bought a pair in June 2024. They sounded great but after 4 months the left earbud just died. There was no physical damage, it was fully charged - but it stopped working completely. I returned the pair to Sennheiser and they said it couldn't be repaired and sent me a replacement. Fine - until, another 4 months later, the left earbud of the replacement pair stopped working in exactly the same way. Clearly there is a design fault as it's too much of a coincidence for exactly the same problem to affect two different pairs in such a short timeframe. I'm currently trying to get a refund from Sennheiser because what's the point of getting them replaced again, but they have refused as I didn't buy it directly from them. So I've contacted Amazon and they say I have to get the earbuds back from Sennheiser, then send them off to the Amazon service centre to be checked before they will refund them. So much hassle and meanwhile I am still without a working, reliable pair of earbuds.
