Great sound quality
These earbuds felt a little quiet at first compared to my old headset, but after the first month of using them and some audio level adjustments, I can safely say that I won't be going back to headsets.These earbuds have amazing sound quality and low latency which has made them my absolute go-to audio equipment for gaming. I'm able to hear every footstep or reload

Sennheiester wired headphones
These headphones are very well made and great sounding they come with several ear pods even for people with small ear Channels for you to choose from they are a little expensive but worth the money from Amazon ….

I guarantee that one speaker will stop working within a year
This was sadly the last time I'll buy headphones from Sennheiser. The sound quality is excellent but every time I've bought headphones from this company, one the headphones/speakers stops working. I'd say the average length I've gotten out of them is 6 to 9 months, however, on this purchase they lasted all of 5 weeks before the left headphone went! I've seen it mentioned in other reviews too so I know its not just me being unlucky. This company has some sort of design floor with their in ear headphones. I've sent them back for repair but no doubt the same thing will soon happen again. Plus I'm now left with no headphones. I give up!

Hied price low quality
Very expensive and awful quality. I bought it 2 months ago and the ear tips always came out and now one headphone is broken. It's perfect only to use in the office or the house but not in sports activities.

Keep falling out my earTried the different attachenrvts & still not joy so maybe my ear hole shape 🤷🏻♂️The sound quality is ok nothing special but they weren’t exactly expensive.Seems to me all the well know top brands that were once a standard use indeed lowered their standards to cater for the budget market which I guess is ok but they really should be more honest & have like a rating systemI think it’s a case of you get what you pay for here even though they only cost pence to produce.

great value for money
Superb non-snag cable, track skip button and 3 additonal different sized earpads. Then the sound, Senhiesser alwasy give detail and a kick of bass without being overwhelmng. I had to redue the bass a little on my Samnsung phone but its easy to get the balance that you want. Not tiring to listen to for long persions and comfortable witht he standar eap pads for me. What's not to like?
