Our Active S-series of tips are our most affordable option. The foam is more porous, so you’re not going to achieve the same level of sound isolation as you would with our other series of tips. However, the foam is more durable. This makes it a good choice for active users or for those using inexpensive IEMs during workouts, high mileage users, etc.
The Isolation T-series and Isolation Plus Tx-series are ideal for maximum isolation and sound quality. Since our tips are compressible and then expand in the ear canal to create a custom fit, you are competing less with outside noises. This allows you to turn down the volume and give your full attention to the music. (Or podcast or audiobook - much harder to crank up!)
Our Comfort Ts-series and Comfort Plus Tsx-series is where things get a little more subjective. Some users prefer the spherical shape of these tips – particularly if they have a shorter bend to their ear canal. In some cases, customers find they receive better sound isolation when using the Ts or Tsx tips. Of course, tip experience is always going to be subjective due to the individual shape of the ear canal.
The Professional P series of tips has a threaded core, so you’ve probably noticed that it is not compatible with most earphones. The length and tapered design allows for deep insertion, providing maximum noise reduction and ear retention.
In regards to the Comfort Plus (Tsx-series) and the Isolation Plus (Tx-series) this is simply referring to the addition of the integrated Wax-Guard. The size of and the material of the foam is exactly the same. The integrated Wax-Guard is acoustically transparent while protecting your device from wax, sweat and other debris. These things can enter the sound port of your device, diminishing the quality of sound over time.
