Studio-grade clarity, adaptive noise cancelling and 38 hours of battery. The pair owners keep reaching for, at half the flagship price.

Selling fast: only 38 charging-case bundles left at this price.
No marketing rounding, no filler. Three engineering choices you will hear on the first track and feel by the end of the day.
Adaptive noise cancelling measures cabin roar, office chatter and street noise, then quietly removes it. Transparency mode lets a single tap bring it all back, so you hear the announcement without lifting a finger to the buds.
Eight hours of continuous play in the buds, with the pocket-sized case holding thirty more. A ten-minute top-up returns four hours, so a forgotten charge never ends your evening early.
At 4.6 grams each, Cobalt Pro sits light and stays put. The included extra-small and large silicone tips seal out noise and lock in bass, whether you are running intervals or sitting through a four-hour flight.
Everything you need to be listening within two minutes of opening it. Select an item on the ring to inspect it.

Adaptive cancelling on low-frequency drone, the roar that tires you out on long commutes.

Buds plus case at moderate volume. A full week of commutes between charges for most owners.
Leading flagship: 24h
Stayed sealed through high-impact training in our wear-panel of 400 owners over 30 days.

The train just goes quiet.
I commute 90 minutes each way and the noise cancelling genuinely removes the carriage roar. I get the full week in before the case needs charging. Best audio purchase I have made in years.
They stay put when I run.
I bought these for the gym and ended up wearing them everywhere. Sweat has not been an issue, the fit test in the app got my seal right first time, and the bass is properly there.
Half the price, and honestly better.
I had the flagship pair from a much bigger brand and returned them for these. The adaptive ANC handles open-plan office chatter better and the case lasts noticeably longer. No regrets.
Transparency mode is brilliant.
One tap and I can hear the platform announcements without taking them out. Calls are clear too, nobody has asked me to repeat myself once. The 45-day window meant I could buy with zero worry.
Fantastic, took a day to settle on tips.
Sound quality is excellent and the battery is no joke. I needed the small tips rather than the default mediums, but once swapped the seal and noise cancelling were perfect. Glad they include four sizes.
Next-day delivery, listening that evening.
Ordered in the afternoon and they arrived the next morning, fully charged. Setup was two minutes. The graphene drivers make my old playlists sound new, you hear detail that was just not there before.
Order today, use Cobalt Pro through every commute, run and call. If they are not the best earbuds you have owned, send them back inside 45 days for a full refund, shipping included. Keep them and you are covered by two years of warranty. The risk is entirely ours.
