Slimmer than ever
The Wavell 4 Sleep Pro is ultra-compact and only 10 mm deep, designed to disappear even in the smallest ears. The comfortable and compact design lets you rest on your pillow without any discomfort. They are ideal for those who prefer sleeping on their side.

Peace in your ears – peace of mind
SleepSeal™ ear tips rest gently in the ear canal without penetrating like traditional in-ear headphones. The design ensures maximum comfort, and combined with 360° noise masking, it effectively reduces snoring, traffic, and voices.

New: Full control with Wavell Connect
Take full control of your sound when falling asleep. Through the Wavell Connect app, you can customize the audio, adjust noise reduction, and preset when the headphones should turn off. Personalize your Wavell 4 Sleep Pro to create the exact sleep experience that works for you.
SLEEP MODE : ON
Set the sleep timer so the sound automatically turns off when you’ve fallen asleep, preventing any harm to your ears from listening all night.
Fall asleep without irritation

Active Noise Cancellation (ANC)
Effective ANC (noise reduction) of up to 20 dB dampens deeper background sounds, allowing you to relax even if you have a snoring partner or lively neighbors. When you need peace and relaxation, even the smallest noises can be disruptive. That’s why it’s important to create a sound environment that helps you fall asleep and get the rest you need.
NightFit™: Designed for sleep, built for comfort
NightFit™ ensures a flexible and pressure-free fit. The soft silicone wing keeps the headphones in place all night without causing irritation or pressure. The wing ensures the headphones stay secure even without being inserted deep into the ear canal. The design provides maximum comfort, allowing you to rest undisturbed.
Choose your own dream playlist
Listen to white noise, nature sounds, or music. Different sounds work best for different people, so you can choose your audio across your favorite apps. Hear what helps you fall asleep with Wavell 4 Sleep Pro.

Sleep Timer & Sleep Mode
SLEEP TIMER: Protect your ears while you sleep
Set the sleep timer so the sound automatically turns off when you fall asleep, preventing any harm to your ears from listening all night.
SLEEP MODE: No interruptions
Sleep Mode disables touch controls so you won’t accidentally wake yourself during sleep.

Battery for the whole night?
Set your sleep timer, lay your head on the pillow, and let calm take over. The headphones are so small that you almost forget they’re there. That’s also why they have a smaller battery that doesn’t last the entire night. Once you’ve fallen asleep, they turn off quietly, without any sounds or voice prompts. It’s our way of taking care of your ears and your sleep.

SLEEP TIMER
Let the headphones fall asleep with you. Set them to turn off after, for example, 30, 45, or 60 minutes, so your ears can rest once you’ve fallen asleep. This way, you can enjoy the sound as you relax without it disturbing your sleep later in the night.

Where can I download your app?

My headphones won't connect to the app?
If you experience that one of our models, which is compatible with our Wavell Connect app, does not connect automatically to the app, and just stands there thinking, it is because the headphones are in sleep mode. All you need to do to "wake" them is to press 2-4 times on either the right or left headphone. Then they will connect automatically right away again.
Can your headphones and speakers be used with all devices?
Yes, all our audio products can be connected to all devices via Bluetooth.
I have challenges with a product?
If you experience challenges with a product bought from us, you should either contact us at info@wavell.dk or see if you can find a solution via our product support page. See here.
The sound has become lower in one of my headphones?
Often when our customers experience this problem, it is due to earwax. Earwax can be incredibly difficult to see in the filter, but can be removed. We have searched long in the office, and found that the best solution when it has set in, is to use sticky tack to remove dirt etc. You should press a bit with the sticky tack, so that it gets moved into the small holes in the filter. Feel free to repeat about 5 times, and then it should be solved. If you experience that the sound only partially comes back, you can continue a couple of times until it is completely back. If this should unexpectedly not help, then you can advantageously order our cleaning tool.
