## Questions & Answers

**Q: Hi, are they extremely comfortable in ear ?**
A: Whilst i dont have a  problem with sound, or the  comfort, i have  series  issue about how  readily and  easily the  actual rubber  ear buds comes off  on removing the headphones from your  ear, leaving then potentially deep within your  ear. The  mearest hint of  a fit, with the phone barely inserted  means it  can result in the rubber bud  staying lodged  within your  ear. Comfort fine, retrieveing a  bud  from your  ear, thats NOT GOOD and a different matter . This isnt  from putting the  bud in deeply either  as the name suggests ypu can. if you did, it could  result in tweezers or a  trip toa  doctor. Even when barely inserted this  can happen  !

**Q: Will these work on a MacBook for conference calls etc.**
A: Yes, I us men in my iPhone, my MacBook and my mac desktop. Good sound quality and the microphone works well enough too. Quite comfortable for long calls.

**Q: Does it have a microphone? The description doesn't say anywhere. Thanks**
A: yes
Microphone sensitivity
- 44dBV/Pa

**Q: Can noise isolation be turned off?**
A: There is no noise cancelling on them that i am aware of

Excellent earphones extra strong lead great sound

### ⭐⭐⭐⭐ Good sound quality,well made.
*by P***P on 5 June 2025*

These wired ear buds give well rounded sound with a bit extra bass. A good seal in ear is easy to achieve with the selection of silicone cups that are in the box. As a result outside noise is interference is markedly reduced. Cable entanglement is not a concern due to the type of cable used. The in-cable switch start/stop and track advance works well. My only niggle is the 3.5 mm jack is in some cases a bit tight to plug in or remove. Overall a good product in my opinion.
