Question 1

What is the open-ear design and does it block outside noise?

Accepted Answer

ALT Buds Open use an open-ear design: the buds rest just outside your ear canal on a liquid-silicone hook with a memory-wire core, rather than sealing inside it. This keeps you aware of traffic and surroundings and stays comfortable for long wear, but because nothing seals the ear, they do not offer active noise cancellation and let some ambient sound in by design.

Question 2

How is the calling quality on the ALT Buds Open?

Accepted Answer

ALT Buds Open are built for hands-free calling with a four-microphone array and AI-powered noise reduction that keeps your voice sharp whether you're at your desk or mid-run. As with any wireless earbuds, overall clarity still depends on your network strength and the amount of noise in your surroundings.

Question 3

Do the ALT Buds Open announce the caller's name or number?

Accepted Answer

No, the ALT Buds Open do not read out the caller's name or number. Instead you will hear a tone alert through the earbuds when a call comes in, and you can answer or reject it using the controls. To see exactly who is calling, glance at your phone screen before picking up.

Question 4

Are the ALT Buds Open water-resistant?

Accepted Answer

Yes. The ALT Buds Open carry an IPX4 rating, making them resistant to sweat and light splashes during workouts and daily use, but they are not waterproof and should not be submerged or worn while swimming. Always wipe them dry and let them air out completely before returning them to the case or charging.

Question 5

What is the battery life and charging time of the ALT Buds Open?

Accepted Answer

The ALT Buds Open deliver up to 35 hours of total playtime with the charging case, with real-world runtime depending on volume and usage. A full charge takes about 90 minutes, and with Instacharge a quick 10-minute top-up delivers up to 3.2 hours of playback — handy when you're heading out and short on time.

Question 6

How do I charge the ALT Buds Open, and what if they aren't charging?

Accepted Answer

Charge the ALT Buds Open by connecting the case to a PC, laptop or any standard USB adapter with the supplied cable, then place the buds inside. If they will not charge, clean the charging contacts, make sure the buds are seated correctly and try a different port; if the issue persists, register a complaint at gonoise.com/pages/register-your-complaint.

Question 7

How do I check the battery level of the ALT Buds Open?

Accepted Answer

Once paired, open the Bluetooth menu on your smartphone and the battery level appears beneath the 'ALT Buds Open' entry. You can also see it in the connected Noise Audio app, and on iPhones in the battery widget, so you always know how much charge is left in the buds before heading out.

Question 8

What devices are the ALT Buds Open compatible with?

Accepted Answer

The ALT Buds Open work with virtually any Bluetooth device, including iPhones, Android smartphones, tablets, and laptops or computers that have Bluetooth. They connect over Bluetooth v6.0 for a stable, efficient link and remain backward compatible with earlier Bluetooth versions, so both newer and older hardware pair without any issue.

Question 9

Can the ALT Buds Open connect to two devices at once?

Accepted Answer

Yes. The ALT Buds Open support dual-device pairing, so they can stay connected to two devices simultaneously — for example your phone and your laptop. You can listen to music on one and switch instantly to take a call on the other without having to disconnect and manually re-pair each time.

Question 10

What Bluetooth version and range do the ALT Buds Open support?

Accepted Answer

The ALT Buds Open run on Bluetooth v6.0 for a fast, power-efficient connection and remain backward compatible with earlier Bluetooth versions. They deliver a wireless range of up to 10 metres in open conditions; walls, furniture and other obstacles between the earbuds and your device will reduce the usable distance.

Question 11

Can I use a voice assistant and is there a companion app?

Accepted Answer

Yes to both. The ALT Buds Open let you summon Siri on iPhone or Google Assistant on Android hands-free. They also pair with the Noise Audio app, which is free on the App Store and Play Store and lets you access the dynamic EQ, customise controls and install firmware updates for the earbuds.

Question 12

How do I turn the ALT Buds Open on and off?

Accepted Answer

The ALT Buds Open power on automatically when you open the charging case and remove the earbuds, and they power off and begin recharging when you place them back in the case and close the lid. There is no separate power button — simply taking them out or putting them away handles it, which also helps preserve battery between uses.

Question 13

How do I pair the ALT Buds Open with my phone?

Accepted Answer

Keep the ALT Buds Open and your phone close together. Open the case and take out the earbuds, which enter pairing mode automatically the first time. On your phone, open the Bluetooth menu, then search for and select 'ALT Buds Open' to connect. After the first pairing they reconnect automatically to the last device whenever you remove them from the case.

Question 14

What should I do if only one ALT Buds Open earbud works, and how do I reset them?

Accepted Answer

If only one side plays, reset the earbuds: remove 'ALT Buds Open' from your phone's Bluetooth paired list, place both buds in the case with the lid open, and long-press the case reset button for 8 seconds until the case LED blinks orange. The buds then enter pairing mode to reconnect. If the issue persists, raise a support ticket at support.gonoise.com.

Question 15

Do the ALT Buds Open have a warranty and how do I register it?

Accepted Answer

Yes. The ALT Buds Open come with a 1-year manufacturer's warranty covering manufacturing defects, calculated from the date of delivery. To activate coverage, register your product at gonoise.com/pages/warranty-registration and keep your order details or invoice handy in case you need to raise a service request during the warranty period.
