Yes, you can change the light settings in the Focal & Naim app. You can dim or switch off the light.

If you have a technical issue, contact your dealer who can supply the Focal certified pieces you need.

Yes, you can play video games while using your Bathys headphones thanks to the Bluetooth apt-X™ adaptive codec, which is low latency.

The serial number of your headphones is on the back of the packaging or inside the left slider of the headphones.

Yes, updates will be proposed to you if they are available for Bathys. You can find them in the Focal & Naim app. The app will notify you when an update is available.

- 30h in Bluetooth® mode and Active Noise Cancelling

- 40h in USB DAC mode

The EQ is consisting of a 5-band graphical equalizer, with 2 predefine modes:
- Home: this mode can be used in a quiet environment, which lightly compresses the top and bottom-end to create a more neutral sound. 
- Loudness: this mode can be used for low volume listening, which balances the decrease level of low and high frequencies.
It’s also possible to customize and save your personal settings. 
- The same EQ will be applied to the sound until you change or turn it off on the app (mobile app is accessible on Bluetooth®) whether you are using Bluetooth®, USB C audio (DAC) or the 3.5mm jack.

If you are using the app on multiple devices, check that Bathys is not already connected to the app on another device. Only one device using the app can be connected to the headphones.

If no other devices are connected to the headphones, then try rebooting the headphones and cleaning the BT devices list.
Check that the application is up-to-date.
The Focal & Naim app can only be used with the Bluetooth® mode.

No, the headphones need power for any type of operation.

If you accidentally dismiss the fast pair pop-up message, sometimes the phone thinks you want to ignore the headphones and the phone will prevent you from pairing with them for about 10 minutes.
- In the Bluetooth settings of your phone, make sure you “forget” all Bathys
- Switch off your headphones
- Restart your phone
- Switch on your headphones
- Enter pairing mode (long press on the Bluetooth button)
- Fast pair should now work.

Some old phones do not correctly respect the stream type requested from the headphones. So, if the apt-X™ adaptive doesn’t work, try updating Phone OS or contact your phone manufacturer.

You can connect to 2 devices at the same time, but only one playing at a time. You can pair up to 8 devices, if you pair more, the oldest paired device will be automatically removed.

We use Multipoint technology which automatically switches from one device to another when several devices are still paired to the headphones, and Bluetooth mode is activated on the devices. It is not necessary to go through the settings. For example: if you listen to music via your tablet and you receive a phone call, when you hang up, the headphones automatically connect to your smartphone.

In Bluetooth, the headphones support: SBC, AAC, aptX™ and aptX™ adaptive. The headphones will automatically choose the best codec available on your device. 
In USB, the headphones support: PCM up to 24 bits 192 kHz.

Best quality is achieved by playing lossless files on your playback device. Where possible combine it with the less compressed Bluetooth codec: aptX™ adaptive for Android devices and AAC for iOS devices.
Thanks to the DAC mode, connected with the USB-C on your device, you can enjoy music without compression and with a resolution up-to 24 bits 192 kHz.

The maximum Bluetooth reach is 15 meters, without obstacles between the playback device and the headphones.

You can choose the voice assistant you want through the Focal & Naim app. 
- Download the app
- While setting up your Bathys’ headphones, Select Google Assistant, Amazon Alexa or Siri. 
- Connect to your account.
 After this, you can use the dedicated button on the right earcup to start the voice assistant.

Unfortunately, some smartphones are not following the apt-X adaptive specifications correctly and it can noise on the Bathys, in this case please try other codecs.

The EQ settings allow you to use the headset according to your listening habits and preferences (increasing or decreasing bass, treble, etc.).), while the Mimi (Mimi Hearing) test lets you adapt and configure the headset's sound to your hearing, so that you always get the best possible sound.

To use the hearing test function, connect the headset to your Bluetoothâ phone, then go to the Focal & Naim app in the "Personalization" section to perform the test. It takes about two minutes.

No, for the test to be configured you need to be in Bluetooth® mode via the Focal & Naim application. However, it remains active whatever the mode, as the settings obtained after the test are stored in the headphones. You can also use it when connected to a jack or in DAC mode.

It is a known issue when using a MacBook that there is an audio imbalance. To avoid this issue, you can download ‘Balance Lock’ for free from the App store. If you would prefer to correct the balance manually then you can access the channel levels in ‘Audio MIDI Settings’.

The Bathys headset USB device is a USB 2.0. It is compatible with USB v1.0, v2.0 and USB HID (Human Interface Device) audio classes. It does not always connect automatically to your device, for various reasons:

• The device connected to the Bathys headset is not configured in Host mode.A specific setting must be activated for USB OTG connection on some devices/phones (note that OTG may automatically deactivate after 10 minutes of USB inactivity on some devices).
• The device connected to the Bathys headset is not compatible with USB Audio and/or USB-HID. The settings for USB Audio routing and/or USB-HID control must be activated for optimum operation of the Bathys headset. We also strongly recommend using Bathys headphones with USB High Speed if possible.
• The device connected to the Bathys headset goes into high-current protection mode. If you connect your Bathys headset to your device without DAC mode selected on the headset, it will start charging with a high current, so your device will go into protection mode. The best solution is to set Bathys to DAC mode, then connect it to your device.
• The device connected to the Bathys headset does not recognize the headset as an audio device, so you may need to restart your phone for this to work.

No - the battery is required to listen to the jack input due it being an active amplification input.

Yes, but it depends on the smartphone you are using. Not all the smartphones support it so you’ll need to verify the USB settings in your smartphone.

The Active Noise Cancelling technology offers several listening options that reduce interaction with external noise. Utilising outward-facing microphones that analyse the surrounding sounds, an inverse frequency is produced to reduce the undesirable background noise. This technology is ideal to enjoy your music, a podcast, a movie, to make a call – all without unwanted interruption. 

- Transparent: Lets outside sound in, to allow clear and easy conversation
- Soft: Limited noise reduction for moderately noisy environments (eg. office, house)
- Silent: Optimum noise reduction for particularly noisy environments (eg. Train, airplane)

Make sure that:
- the earpads are sat correctly on your head and all the pins are fixed
- the earpads are not damaged 
- the fabric and foam inside the earcup (in front of the driver) is not be displaced or removed
- ensure the microphones hidden around the logo on the earcup are not blocked

Yes, if you want to use the active noise-cancelling only (without music), you need to either disable the Auto Standby feature or be using the DAC feature.
If you are in ON mode without music, the headphones will by default to sleep mode after 15 minutes. This can be changed by disabling Auto Standby in the headphones’ settings. If you are on DAC mode, sleep mode will not be activated, so you are able to use the active noise-cancelling.

To restore factory settings, press the '-' and 'ANC' buttons for 8 seconds.

The power output from chargers varies, but using a good quality charger (~ 2 amps), the headphones will be fully charged in about 1.5 hours.

Yes, but it depends on the smartphone you are using. Not all the smartphones support it so you’ll need to verify the USB settings in your smartphone.

Make sure to use a high-quality charger, ideally capable to deliver 5V DC and at least 2A of current.
If your battery is empty and the charger is limited in its power delivery, it is possible that you may hear sporadic  clicks before the battery begins to charge.

The battery capacity is indicated in the Focal & Naim app.
