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 ….

Need to be tweaked if you listen to electric guitar based music
These headphones are good, but you are going to need to make some adjustments on your equaliser for them to sound correct if you listen to guitar based music. The bass and high end are turned up too much so the mid range is lost. They feel like they've been designed out of the box for dance music. It's a fairly simple fix. Just slightly boost the mid ranges on your equaliser and slightly turn down the bass and high frequency and it will get tracks sounding as they are supposed to.

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

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!

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 earphones
Bought these as a gift for someone predominantly using them for gaming - says they are much better than other purpose built gaming earbuds and headsets they have used previously. I looked around for a while at a decent pair of wired earbuds and settled on these as well priced, not breaking the bank, and having decent standards. Would buy again - they aren't going to be the best earbuds in the world for any audiophiles but for most purposes they are a great option.
