The headphones contain magnets that generate a magnetic field which could cause interference with cardiac pacemakers and implanted defibrillators.Keep the product, accessories and packaging parts out of reach of children and pets to prevent accidents and choking hazards.Do not use the headphones at any time the inability to hear surround sounds may present a danger to yourself or others (due to the noise cancelling feature), e.g., while riding a bicycle or walking in or near traffic.Unplug the power supply unit from the wall socket during lightning storms or when it is unused for long periods of time.To reduce the risk of fire or electric shock, do not expose this product to rain, liquids or moisture.If you experience small static/electric shocks while your headphones are connected to a device that is connected to a wall socket, your wall socket might be faulty.

Meet ELSA (Extended Listening Smart Assistant), your new listening conscience. Powered by AI, ELSA actively monitors the harmful volumes that your ears are exposed to and changes your listening habits for the better.i How it worksThis is what happens during ONE ELSA CYCLE:a) Autonomous Volume Assessment- ELSA constantly monitors volume levels that you listen at- ELSA stores and analyzes listening duration at each volume levelb) Healthy Hearing Defense System- Once your ears have been exposed to too much loudness, ELSA automatically adjusts volume to 85dB*c) Behavioral Alert SystemAudio: Just before lowering 85dB, ELSA plays an alert tone**Visual: ELSA lights change from GREEN to BLUE (1st cycle), and BLUE TO RED (2nd cycle)*Auto Volume adjustments can be turned ON and OFF (page 10)ON: AUTO VOLUME adjustments activatedOFF: Visual alerts only. AUTO VOLUME adjustments deactivatedELSA LED LightsGreenBlueRedListening Exposure StatusSafe (First Cycle)Unsafe (Daily maximum noise exposure reached)Unsafe (Twice the daily maximum noise exposure reached. ELSA deactivated.)1. WHAT IS ELSA3 ELSA

**Behavioral alert tones sound different in Bluetooth (Wireless) and Wired modes, because the headset is programmed differently for each mode. To hear the difference, please go to:www.nakamichi-usa.com/hearii. How long does it take for ELSA to adjust volume down to 85dB?iii. Resetting ELSA timerELSA continuously assesses the volume levels you listen at, the moment you switch on the headphones. To reset ELSA timer and data, restart the headphones by powering it OFF and then switching it ON.Listening volume level is NEVER constant. All audio content have louder and softer parts.User will be exposed to ALL volume level ranges. Please expect time taken for ELSA to adjust volume to vary during each session...~ 65% - 75%88dB > L > 83dB480 min~ 75% - 85%93dB > L > 88dB150 min~ 85% - 95%98dB > L > 93dB47 min~ 90% - 95%103dB > L> 98dB15 min100%L > 103dB4 minPLEASE READCombined Volume Levels (Device + Headphones)Volume Level Range (L)Time taken for ELSA to adjust volume to 85dBdBdB1. WHAT IS ELSAELSA 4

iv. IdlingWhen ELSA is idling (music on device paused for extended period of time), ELSA will detect that your ears are not being exposed to loud music and will extend the time to the next Auto Volume adjustment. However, to save battery life, ELSA will switch itself off if it is idling for more than 30 minutes.v. ELSA's independent volume controlOn most traditional Bluetooth devices, the device that is paired with the headphones centrally controls the overall volume level. However, ELSA is designed with an independent volume controller to bring the volume level down to 85dB to protect your hearing. If you find the volume level to be too low even if your device's volume level is high, it is likely that the independent volume level on the headphones is too low. You can further increase the volume by pressing the Vol+ button on the right earcup.vi. Health and safety disclaimerELSA is provided as is without any health and safety guarantees.
