The Fight Starts the Night Before.

Noise is the hidden variable in athletic performance. Poor sleep, a disrupted recovery window, or a fractured pre-fight focus session does not show up on the scoreboard — it shows up in your reaction time. Music SoundPRO is a passive silicone earplug that brings the overall volume down to a safer level to protect your sharpness, your sleep, and your recovery. It removes what drains you without cutting you off from what matters.

The Performance Variable Nobody Tracks

One hour of disrupted sleep reduces reaction time by up to 30%. Ambient noise during recovery — a busy hotel corridor, a training facility that never goes quiet — spikes cortisol and delays the muscle repair cycle your body needs between sessions. Elite athletes control their nutrition to the gram and their training load to the minute. Then they sleep in noisy fight-night hotels and recover in loud physio rooms and wonder why they feel flat on the day. Noise is not a minor inconvenience. It is a performance drain you are paying for every single camp. Music SoundPRO blocks it.

10 years of research and 1,000,000 ears protected

  • Designed for performance environments, not just noise reduction. Music SoundPRO is a passive silicone earplug (SNR 24 dB) that brings the overall volume down to a safer level, so your coaching cues stay audible because they’re loud and close, your music stays present, and your awareness stays sharp.
  • Foam earplugs are the wrong tool for athletes. They kill bass, distort treble, and block everything including the sounds you need. Music SoundPRO filters the noise tax without cutting you off from your environment.
  • Medical-grade silicone construction. Comfortable enough to wear through a full training camp day, in recovery, during travel, or throughout a fight-night hotel stay without discomfort or pressure build-up.
  • Reusable up to 100 uses. Rinse between sessions and store in the included aluminium case — compact enough for a kit bag, a gym holdall, or a flight carry-on.
  • SNR 24 dB passive silicone earplug: Brings the overall volume down to a safer level. Independently certified by PZT GmbH (Notified Body No. 1974). You stay aware of your surroundings while the noise drain is removed.
  • All-day comfort for training camp: Low-profile 2-lamella silicone body sits flush inside the ear canal. No protruding stem, no pressure build-up during hours of wear, no adjusting mid-session.
  • Up to 100 uses per pair: Washable with water and mild soap. Built for repeated use through long training blocks, not a one-off event.
  • HSE-compliant: Approved for gym and industrial noise environments. Meets the same compliance standards required on construction sites and in high-noise workplaces.
  • AI Perfect Fit (AR KI TECH): Upgrade to the custom-fit version and our AI matches your earplugs to your exact ear canal dimensions. 3% return rate vs the industry average of 15 to 20%.
  • Pre-competition focus sessions: blocking out the locker room, the crowd noise, and the pre-fight environment before you step in.
  • Sleep during training camp: fight-night hotels, shared accommodation, early-morning training facilities where noise never fully stops.
  • Recovery protocols: ice baths, physiotherapy rooms, cool-down stretches, and any post-session window where noise-free rest accelerates repair.
  • Meditation and visualisation: breathing protocols and mindfulness sessions that require a clean acoustic environment regardless of where you are.
  • Gym environments and sparring halls with persistent high-noise machinery, music, or crowd noise above safe thresholds.
  • Travel to fights and competitions: airports, hotels, public transport — wherever unwanted noise erodes recovery time between sessions.
  • Snap two photos of your ears with your phone.
  • Our AI determines your exact ear canal size in seconds.
  • Get Music SoundPRO earplugs precision-matched to your ears delivered in 1 to 3 days.
  • No expensive audiologist. No guessing. No earplugs that work loose mid-recovery session, slip out during sleep, or break the seal in a noisy gym environment.

Questions? We've got answers.

Music SoundPRO is not designed for contact sparring where ear protection is a safety requirement. For training environments such as gym floors, conditioning sessions, pad work, or strength and conditioning rooms where persistent loud noise (music, machinery, crowd) is the issue, they perform well. They bring the overall volume down to a safer level while keeping you aware of your coach and your surroundings, because they’re loud and close.

Yes. Arena and cage-side crowd noise at major events regularly reaches 100 to 110 dB. Music SoundPRO is a passive silicone earplug (SNR 24 dB) that brings that down to a level that protects your hearing without cutting you off from spatial awareness. You can still hear coaching instructions and environmental cues clearly.

Training camp accommodation is rarely quiet. Shared hotels, noisy corridors, early-morning facility noise, and light sleepers sharing rooms all disrupt the deep sleep cycles that drive hormonal recovery. Music SoundPRO reduces ambient noise to a level where uninterrupted sleep becomes possible. One consistently quiet night compresses recovery faster than two interrupted ones.

Yes. That is the key difference from foam. Music SoundPRO is a passive silicone earplug that brings the overall volume down to a safer level rather than blocking sound indiscriminately. Speech remains audible because friends and coaches are loud and close, you still hear the music just quieter, and you keep spatial awareness of your environment. Foam earplugs distort and muffle. These do not.

Foam earplugs are designed for industrial noise environments where the goal is to block everything. They crush bass frequencies and distort the high end. For athletes who need to hear coaching, stay situationally aware, or simply want to sleep rather than feel deaf, foam is the wrong tool. Music SoundPRO brings the volume down to a safer level, so you reduce the noise without the underwater muffle of foam.

Yes. Music SoundPRO is made from medical-grade silicone, which is water-resistant and hypoallergenic. They perform the same whether you are in an ice bath, a physiotherapy room, or a cool-down stretch. Rinse with water and mild soap after wet use and they are ready for the next session.

There is no practical limit for a single training camp day. The low-profile 2-lamella silicone body sits flush in the ear canal without creating pressure or suction. Most users report forgetting they are wearing them after the first few minutes. Athletes regularly wear them through six to eight hour event days without soreness or discomfort.

Yes. Visualisation sessions and breathing protocols are significantly more effective in a quiet environment. Music SoundPRO reduces ambient noise to a level where you can maintain focus without interruption, wherever you are — a noisy gym, a hotel room, or a busy training facility. No separate quiet room required.

Yes. Music SoundPRO is independently certified by PZT GmbH (Notified Body No. 1974) with an SNR of 24 dB and meets HSE compliance requirements for high-noise workplace environments. They are a valid hearing protection solution for gyms, industrial facilities, and any environment where noise levels require mandated protection.

Try Music SoundPRO for 40 days through training sessions, recovery windows, fight-night hotels, or any part of your camp. If they do not deliver, contact our customer support team and we will arrange a full refund with no questions asked. We offer 40 days rather than the standard 30 because we know it takes a few sessions to find the right insertion technique and build consistent habits around wearing them.

Recommended by experts and high-performers worldwide

From professionals who depend on controlled sound during high-focus work to acoustic specialists who understand exactly what noise does to a body under performance stress. Bollsen is the daily choice for people who treat their edge seriously.

DJ UMEK
Techno Legend and Hearing Protection Advocate

“Concentration is the whole game. When I am preparing for a long set or working in the studio at high intensity, the quality of what I hear and how much I can control my acoustic environment determines the quality of my output. I wear Bollsen because precision matters. You cannot perform at the level this industry demands if your ears and your focus are being pulled in every direction.”

Nova Acoustics
Independent Hearing Protection Specialists

“The research on noise exposure and physical recovery is consistent: sustained ambient noise above safe thresholds raises cortisol, fragments sleep architecture, and delays the physiological repair process. Proper music earplugs like Music SoundPRO are effective in performance environments precisely because they bring the overall volume down to a safer level without the underwater muffle of foam. The athlete stays aware and protected at the same time. That combination is what makes the difference between a tool people use and one they leave in the kit bag.”

1,000,000 People Have Chosen Bollsen Earplugs

I am a middleweight competing at regional level. Started using Music SoundPRO during training camp for sleep and pre-fight focus. My sleep tracker showed an average of 18 extra minutes of deep sleep per night during the six weeks I wore them consistently. Fight night I used them in the warm-up room. I walked into that cage calmer and sharper than any previous camp. Small thing, real difference.

Marcus T. / Verified Review, Trustpilot

I train six days a week and our gym has the music at 95 dB minimum. I started wearing Music SoundPRO for sessions and the ear fatigue I had been writing off as normal training tiredness dropped noticeably within two weeks. SNR 24 dB of passive silicone protection is the real deal. The certification is from PZT GmbH, an accredited testing body, not a marketing number. Exactly what I needed.

Kieran F. / Verified Review, Trustpilot

I coach a boxing squad and bought these for myself first, then for four of my fighters. The difference in how relaxed they are in the dressing room before bouts has been visible. Two of them now use them every night during camp weeks. One told me his reaction drills at the end of a hard week felt sharper than they used to. I cannot attribute it all to the earplugs but the correlation is there.

Priya N. / Verified Review, Trustpilot

I compete in amateur MMA and have fought in arenas where the crowd noise during walk-outs is genuinely disorienting. I started wearing Music SoundPRO from the warm-up room through to the cage entrance. The crowd is still there, I can still hear the corner, but the overwhelming noise wall that used to spike my heart rate early is gone. First fight I used them I landed a cleaner game plan than I had in the previous three bouts.

Darragh O. / Verified Review, Trustpilot

I run at elite level and travel to competitions most weekends. Hotel rooms during competition trips are rarely quiet. I started wearing these the night before races and tracked my sleep quality against previous competition nights. Three consecutive months: average deep sleep up by 22 minutes on competition eve compared to the six months before. Race times that month were personal bests across two distances.

Sophie R. / Verified Review, Trustpilot

I do strength and conditioning work in a commercial gym where the noise floor sits at around 90 dB. Using Music SoundPRO for every session for the past four months. My training log shows better focus blocks during technique work and fewer mental fatigue notes at the end of long sessions. The 40-day guarantee meant I had no risk trying them. I have now bought a second pair to keep at the gym permanently.

Jakub W. / Verified Review, Google

I use ice baths and contrast therapy three times a week. I started wearing Music SoundPRO during the sessions six weeks ago. The difference in how quickly I can settle into a calm breathing pattern during the ice is significant. I used to need two to three minutes to regulate. Now I am calm within 30 seconds of getting in. I attribute most of that to removing the gym noise that was keeping my nervous system activated.

Callum B. / Verified Review, Trustpilot

I do daily visualisation sessions as part of my fight preparation. Finding quiet in a training camp environment is nearly impossible. I started using Music SoundPRO for my 20-minute morning sessions and the consistency of the practice improved immediately. I can go deeper into the visualisation without being pulled out by corridor noise or other athletes moving around. Three camps in a row now with these as a fixed part of the routine.

Aisha M. / Verified Review, Trustpilot

I work as a sports physio at a busy clinic. Several of the athletes I treat have started using Music SoundPRO during treatment sessions on my recommendation. The ones who wear them during soft tissue work report noticeably lower perceived pain scores and are visibly more relaxed on the table. Noise reduction during recovery is underrated. I now recommend these to every athlete I work with who is training through a high-volume block.

I messaged Bollsen asking whether the standard size or AR KI TECH was better for use during sleep, given that I move around a lot. They replied within a few hours with a specific recommendation and explained the difference in seal quality between the two. That level of detail before I had spent anything convinced me. Ordered the AR KI TECH version, arrived the next day, perfect fit from the first night.

Roisin C. / Verified Review, Trustpilot

Ordered Music SoundPRO AR KI TECH on a Tuesday evening. Uploaded my ear photos the same night and had my size recommendation by Wednesday morning. The earplugs arrived Thursday. I wore them during a two-hour recovery session that afternoon. The process from order to use was 48 hours. For something I needed ahead of a competition that weekend, that turnaround mattered.

Nathan J. / Verified Review, Trustpilot

I used the 40-day guarantee when the first size felt slightly loose during sleep. Bollsen sent a replacement size without asking me to return the originals. Two emails, no paperwork, no questions. The replacement fit was correct and I have been using them every night through two full training blocks since. I have since bought pairs for three teammates who asked about them after seeing mine.
