Marc Henshall,

It's a common misconception that Shure earphones "lack bass". In reality, less than 1% of earphones returned to Shure service for "lack of bass" are defective. In almost all cases, the cause is a due to how they're fitted, and here's why:

In order to have "full bass" with Shure earphones, each earphone must be properly seated in the ear canal, and the ear canal properly blocked. The smallest of air leaks into the ear canal will reduce the bass significantly. The tricky part is, each person's ear is different, and for this reason, Shure supply a wide variety of flexible earphone sleeves to help provide a good fit in the majority of cases.


Find your own Personal Fit

It's important to experiment with the provided sleeves to find the best fit for your ears. Once the ear canal is properly sealed, the bass response will be noticeably improved. The seal you create is also integral to sound isolation (a key advantage to Shure earphones). If you would like to know more about Sound Isolation, check out our blog post "what's the difference between noise cancelling and sound isolating earphones".

Custom Ear Moulds

A small percentage of the population will have ear canals that do not suit any of the provided sleeves. In this case, it's best to have custom ear moulds created by a specialist company, such as: Custom IEM
