Read this user manual carefully and completely before using the
product
Always include this user manual when passing the product on to third
parties.
Do not use an obviously defective product.
Preventing damage to health and accidents:
Protect your hearing from loud volume levels. Permanent hearing
damage may occur when headphones are used at high volume levels
for long periods of time. Nakamichi ELSA headphones sound great at
low and medium volume levels.
Turn the volume down on your device before placing the headphones
on your ears, then turn the volume up gradually until you reach a
comfortable listening level.
Keep the headphones at least 10cm/ 3.94” from cardiac pacemakers
or implanted defibrillators. 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. Consulting an electrician to investigate the
wiring of the house/office is strongly recommended.

ELSA 2

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 works
This 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 level
b) Healthy Hearing Defense System
- Once your ears have been exposed to too much loudness, ELSA
automatically adjusts volume to 85dB*
c) Behavioral Alert System
Audio: 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 activated
OFF: Visual alerts only. AUTO VOLUME adjustments deactivated

**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:

ii. How long does it take for ELSA to adjust volume down to 85dB?
iii. Resetting ELSA timer
ELSA 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.

iv. Idling
When 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 control
On 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 disclaimer
ELSA is provided as is without any health and safety guarantees. In
association with the product, Nakamichi makes no warranties of any
kind, either express or implied, fitness for a particular purpose. Use of
the product by a user is at the user's risk.
vii. Bluetooth

v. Pairing the headphones with device
To pair your headphones with a Bluetooth device, you have to use
the Bluetooth search function. In order to successfully establish a
connection between the headphones and a Bluetooth device,
Bluetooth on your device must be activated.
ELSA headphones complies with the Bluetooth 4.1standard.
To transmit data wirelessly using Bluetooth technology, you have to
pair your headphones with compatible Bluetooth devices that
support the following profiles.
- Hands Free Profile (HFP)
- Headset Profile (HSP)
- Audio/ Video Remote Control Profile (AVRCP)
- Advanced Audio Distribution Profile (A2DP)
- Device ID Profile (DIP)
When you power on the headphones, the headphones will automati-
cally try to connect to the last two connected Bluetooth devices. The
headphones can save up to eight previously paired Bluetooth devices
connection profiles.
If you pair the headphones with a ninth Bluetooth device, the saved
connection profile of the least used Bluetooth device will be overwrit-
ten. If you want to re-establish a connection with the overwritten
Bluetooth device, you have to pair it with the headphones again.
CAUTION
Danger of malfunction!
The transmitted radio waves of mobile phones can impair the
operation of sensitive and unprotected devices.
Only make calls with the headphones in locations where
Bluetooth wireless transmission is permitted.
