LET'S ANSWER YOUR QUESTIONSā
For proper installation, our XSound helmet speakers need to be touching your ears during use inside your helmet. You may use the included foam spacing pads to achieve this (XS3 only).
We also recommend that the helmet speakers are mounted in a more forward and lower position in the ear pockets to accommodate your ears more effectively.
Failure to do the above may cause damage to the speakers ā the main cause being the volume gets turned up past acceptable levels to compensate for any wind and engine noise introduced by any gaps.
It is recommended to test and connect the helmet speakers directly to your smartphone or music player first using the 3.5mm cable and holding them to your ears as your music plays to confirm the optimal position before mounting them in your helmet.
Try connecting the helmet speaker directly into a smartphone or music player and play at the same volume. If the crackling or popping disappears, your motorcycle headset or Bluetooth receiver is likely the cause. They tend to not support low-frequency outputs because typically their stock speakers do not deliver audio in that range.
While our XSound series of helmet speakers are designed and tested to be able to play at max volume on smartphones and music players without distortion, IASUS does not recommend listening to music at excessive levels which may lead to temporary or permanent hearing damage. Please proceed with caution.
As the XSoundās quality makes them the ideal choice to replace the stock speakers which motorcycle headsets come with, we are unable to confirm the compatibility with every model of motorcycle headsets (and Bluetooth receivers) out on the market.
For tight fitting helmet enclosures, volume level and sound quality of your XSound 3 may be diminished if the ears get folded after putting on your helmet. When this happens, the audio does not have a direct path to your ears, hence the reduced volume and poor sound quality. Since it is difficult to access your ears due to the tight fit of your helmet, we included a Tab that was specifically to reach that are through either the space from your visor (when opened) or from the bottom of your helmet. The thin tab should be able to reach and be able to position your ears correctly. Also note that to optimize the sound quality of the Xsound 3, the speakers need to sit flush and directly on the ears. Sometimes, pending how you pivot the helmet the ear cavities are not aligned properly with your ears and that may also affect your audio experience. In order to benchmark the audio, we recommend that you listen to the helmet speakers on your ears directly prior to installation to have a feel for the sound and volume levels. The Xsound 3 package also includes a key ring for the Helmet Speaker Tab so that it can conveniently double as a great motorcycle key holder. This way you wonāt forget to bring it or loose it when you are riding.

I run a Cardo edge with the Iasus Ear3H amp and these XSound4 speakers. I also wear earplugs when riding. They are PUNCHY and have a lot of bass. You can feel the bass vibrate in your helmet and against your ears with this speaker paired with an amp. The JBL speakers donāt get nearly as loud without causing a lot of distortion. The bass on the JBLs is also weak, Even when tested with an amp.
With the XSound4, Iām able to crank the volume knob up to about 80 percent on the amp without any distortion. After that, it starts to get distorted but you really donāt need it any louder. Being able to increase the volume that much makes it so I can hear music clearly no matter the wind or speed Iām going. I also ride a naked bike so Iām getting a lot of wind when riding.
Iāve noticed these speakers naturally have more bass when compared to the Cardo so I did adjust my EQ settings to have less bass to compensate. It sounds perfect to me on most genre songs when using both Spotifyās EQ Bass Reduction setting and Cardo appās bass boost setting.
Overall, I highly recommend it only if you plan on running an amp in your set up. JBL and Xsound4 are about on par without an amp. I do not think the Cardo alone can make use of the potential of these speakers. With an amp, there is a clear winner. So if youāre looking for an upgrade for your Cardo, an amp is a must otherwise youāre better off just sticking with the JBLs that came with it.

These speakers sound amazing. They are a little thick and it took awhile to get them placed just right so they donāt put pressure on my ear but I finally got it perfect and love them.

The IASUS amp and XSound 4 speakers is an awesome UPGRADE to my helmet.
The only thing that I didn’t like was it only came with one coiled cord in the box when I need two of them. Fortunately, I ordered two amplifiers, in which I was able to take the cord from that one to complete the installation of the amplifier. I informed IASUS about the cords and they’re sending me some additional cords. For my extra amplifier.
