The Foam Tips That Last All Day

Do your ears ever hurt when you take your headphones out after a long day at the office? Well, those days are gone. An alternative earbud is here that allows users to enjoy their favorite music and podcasts all day without discomfort. Meet the Comfort 100 Foam Tips.

The Comfort Series (Ts/Tsx-Series) Foam Tips have been designed for all day use. All Comply™ Foam tips are comfortable, but these Comfort 100 Foam Tips take natural usage to the next level. With their innovative configuration, the Comfort 100 Foam Tips utilize a spherical design that puts less stress on the ear canal. Due to their unique design and makeup, the Comfort 100 Foam Tips gently mold to your ear canal to deliver peak sound quality while filtering out background noise. By employing our proprietary foam blend, the new Comfort 100 Foam Tips are 30 times softer than silicone, resulting in all day comfort.

When tunneling sound directly into your inner ear canal, you’ll be able to hear a fuller sound quality than you would with standard headphones. The Comfort 100 Foam Tips are perfect for those who listen to music throughout their work day or for those who have long commutes. You’ll be able to block out crying babies, blaring horns, and your fellow passengers and focus on your entertainment of choice. The Comfort 100 Foam Tips are the ultimate in-ear headphone upgrade.

Best for:

Commuters, travelers, audiophiles, music-enthusiasts, and office workers. With the Comfort 100 Foam Tips you can listen at work, on your morning commute, or on long-distance flights with comfort and ease.

Maximum Earphone Comfort

Comfort 100 Foam Tips are round shaped and designed for less ear canal contact to ensure comfort over long listening sessions. When in use, body-heat activated memory foam creates an ultra-soft, comfortable listening experience by conforming to your ear canal. Comply™ Foam is 30x softer than silicone, reducing ear irritation and fatigue, allowing for all day use and enjoyment.

External Noise Isolation

Engineered to create a custom ear canal seal to block out external noise and environmental distractions, the Comfort 100 Foam Tips are the next best thing in noise cancellation. Enjoy music without raising the volume to compensate for outside noise. Comply™ Tips provide 2x more dB reduction than standard silicone earbuds.

Superior Audio Experience

With a perfect ear canal seal, Comply™ tips funnel pure sound directly into the ear. Maximize your listening experience with enhanced bass and exterior noise cancellation. With our Foam Tips, you’ll hear music how it is supposed to be heard with all its highs and lows.

Secure In-Ear Fit

Our proprietary memory foam has been crafted to expand to fill the unique shape of your ear canal, creating a custom, snug fit to dramatically increase in-ear retention. This allows for each pair of Comfort 100 Foam Tips to be custom molded to each listener’s ear. Whether you’re running to catch a train or taking a quick lap around the office, we guarantee that your Comfort 100 Foam Tips will stay in place.

WaxGuard™ Protection For Cleaner, Clearer Sound Quality

Our unique WaxGuard™ is available in the Comfort 100 (Tsx-Series). The transparent filter inside the Foam Tips keeps earwax and debris out of the earphone’s soundport without altering the acoustic integrity of your music. These WaxGuards™ will ensure that your Comfort 100s maintain their high sound quality over time.

The Perfect Companion For That Perfect Cord

Did you spend months trying to find the perfect set of headphones only to discover that their tips are sub-par? We understand that everyone’s preferences are different. Maybe you want a cord that has no controls on it, or perhaps you feel strongly about the arrangement of drivers utilized to create your perfect sound. Whatever your preference, know that our Foam Tips can make that great set of headphones even better. Our Comfort 100 Foam Tips fit with most major headphone lines.

    I recently purchased a pair of MiFo True Wireless earbuds.
    The buds are ok but the fit in the ear was only just. when you moved your mouth the seal was broken.
    As the MiFo are not on your list I took a punt and ordered the Comfort 400 as they sounded like what I was looking for.
    I got these Comfort 400 and they fit beautifully.
    They stay in, block out virtually all outside sound and add to the bass which the buds were lacking on.
    They are super comfortable to wear and I normally struggle with things in my ear passage.
    The only problem is they too thick to fit in the charging case, my fault for not researching more.
    I have ordered the Truly Wireless foam earpieces and am hoping they will fit in the case which will be awesome.
    Only word of advice, do more research or you will spend extra coin you shouldn't have.
    I am waiting anxiously for the new ones in the post.

  2. Comfort is amazing

    Love the memory foam. These feel exactly how you'd expect from their name, comfortable.
