Sound isolating headphones – also known as Ear Canal Headphones(ECH’s), In Ear Monitors(IEM’s) or even sound isolating headphones, are placed into the ear canal and effectively seal your ear with their small rubberised ear-tip sleeve. They are small, lightweight and very portable. Sound isolating headphones typically have a bit of a spongy membrane which helps them fit comfortably in the wearer’s ears. A few earphones provide good sound isolation: Etymotic Research ER-6i Isolator In Ear Earphones, Ultimate Ears TripleFi 10 Noise Isolating Earphones, just to name a few.
Sound cancelling headphones on the other hand uses a device to cancel out ambient noise.
Sound canceling headphones are great for commuting as you can relax and enjoy what you are listening too while there is noise around you. They are also great for travelling by aeroplane as the engine noise is almost completely blocked by the earphone isolation tips.
Although sound isolating headphones and the humble ear bud headphone may look similar, sound isolating ear canal headphones offer much better quality sound reproduction than the humble ear bud headphones. Sound cancelling headphones actually seal within your ear and offers the advantage that ambient noise is effectively eliminated and you can enjoy crystal clear audio. This gives an ‘in your head’ sound that is particular to this type of headphone.
The major advantage of sound isolating headphones is that they keep the audio inside your ear and the noise outside – they isolate your ear from the outside world by up to minus 20dB.
Important note about safety while listening:
While listening with sound canceling headphones you really are audibly isolated from the external world and need to rely completely on your visual senses.
The two major forms of sound cancelling headphones:
- Ear Surround Model for Sound Cancelling Headphones
The ear surround model works somewhat like a pair of air muffs. As well as passively reducing the sound getting into the ear canal, the cancellation technology reduces noise even further. They are well cushioned but several people find them heavy and when worn for long periods of time to be hot and sweaty.
- Over Ear Sound Canceling Headphones
The over ear surround acts as a passive sound eliminator. The on ear version of sound cancelling headphones is a lot lighter but they do not cover the complete ear area. With more airflow the trade off is less noise being eliminated. They are also less capable of filtering out loud noises. Cushioning helps add comfort to the ears, but some individuals find them sweaty when used for longer periods of time.
If you use sound cancelling headphones on a regular basis such as for your job or travel, you may need to transport them safely. The final accessory you should look at is the carry case that is provided. Soft cases are easier to fit into odd spots in your luggage or hand bag, but they do not provide the level of protection a hard case will.
