Review: Great Ear-canal Headphones. - Note 1: This is only the 2nd pair of ear-canal headphones I have used. Note 2: I have bought these for music listening purposes only. Pros: They are lightweight, comfortable and come very well packed. They have good length of cord and provide very good sound from: cassette player, Android Phone and mp3 player (Boom!). Was very impressed. There are numerous ear tips supplied but I found Aiivioll Silicone Ear Tips give more bass and fitted my ears better. I found also that you do not need high volume as they have high sensitivity. This means the battery driven or rechargeable devices should be able to play for longer. Cons. Wire noise can be experienced when cable banged/tapped due to high sensitivity.
Review: Comfy and good bass - I think these sound fantastic good bass, good noise cancelling and a comfy fit.

## 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

*by B***J on 16 May 2026*

I think these sound fantastic good bass, good noise cancelling and a comfy fit.

### ⭐⭐⭐⭐ Ok for everyday use
*by C***O on 25 January 2022*

I liked these headphones, decent sound for everyday use and making calls. Negative is that you could hear throught the earphones when the cord was rubbing against something and they didn't last nearly as long as they should have with one ear losing sound after about a year.
