Congratulations on purchasing your new Acoustic Research High Fidelity Hi-Res In-Ear

Please read these instructions for quick tips on using the earphones.
Unpack
Make sure you have the following items in the product package:
• Audio cable with 3.5 mm TRS Stereo plug
• Audio cable with 4.4 mm TRRRS 5-pole plug (E10 only)
• Bluetooth Audio cable
• USB charging cable
• Carrying case
• Silicone rubber ear tips* (Size: S, M (pre-installed) & L)
• Memory foam ear tips* (Size: S & L)
*If necessary, change the ear tips to a different size to make sure they snugly fit in your ears.
Connecting to the audio source
You can connect the earphones to your audio source through Bluetooth Audio or conventional
cable connection.
• For Bluetooth Audio connection, use the Bluetooth Audio cable.
• For conventional cable connection, use the audio cable with 3.5 mm TRS Stereo plug or
the audio cable with 4.4 mm TRRRS 5-pole plug (E10 only).
In all cases, you have to first connect the required cable to the ear pieces.
Connecting to the ear pieces
Connect the cable connectors to the corresponding ear pieces. Make sure the “L” or “R” mark on
the cable connectors and ear pieces are matching and facing the same side (see Fig. A).
Wearing the ear pieces
Make sure the cables go around the back of your ears (see Fig. B).
Bluetooth Audio
Charging
For best performance, fully charge the Bluetooth Audio cable before use. Connect the charging
port 3 to a USB power source (e.g. computer or USB charger) with the USB charging cable. Un-
plug the USB charging cable when charging is done (the indicator 4 changes from red to blue).
Switching on/off
• Press and hold O 2 for about 1-2 seconds to switch on or off.
• If the indicator 4 blinks slowly after switched on, the earphones are trying to automati-
cally reconnect with the previously paired device. If you want to pair a new device, see
the next section.
Pairing
1. When switched off, press and hold O 2 for about 6 seconds until the indicator 4 starts
blinking rapidly.
2. Enable Bluetooth on your Smartphone or audio source.
3. Select “E10_E100” from the list of available devices. The indicator blinks intermittently
when pairing is successful.
Controls
• Press O 2 to start or pause playback.
