This wiki page documents the Morse code Easter Egg / ARG that is hidden in Battlefield 1. The Google doc used to populate this wiki page can be found here. Currently, the primary solving hub for this ARG is the Battlefield Easter Egg community.
Headphones and Morse
Pairs of headphones were discovered hidden on some maps. The headphones are indestructible and can be located on every server, as long as they have not already been picked up. It appears that there are 5 sets of headphones per map, although the spawn locations of some pairs remain undiscovered. In addition, only only one pair of headphones spawns upon the initiation of a new round, which makes discovering all of the spawn locations quite difficult. The headphones can be picked up by any player by walking near enough to them. Upon approaching a hidden MCOM station (1 MCOM per map, except Giant's Shadow) wafter having retrieved a pair of headphones, the player will hear some Morse code being tapped out. A player can carry only one pair of headphones at a time, and only the player wearing the headphones will be able to hear the Morse code when near enough to a hidden MCOM.
Headphone Locations

November 15, 2016
On November 15th, Battlefield 1 received an update which changed the Morse code heard on all maps' hidden MCOM stations to the following:
.--. .-. . ...- .. --- ..- ... | -- . ... ... .- --. . | -.-. --- .-. .-. ..- .--. - . -.. .- .-- .- .. - | ..-. ..- .-. - .... . .-. | .. -. ... - .-. ..- -.-. - .. --- -. ...
PREVIOUS MESSAGE CORRUPTED AWAIT FURTHER INSTRUCTIONS
Included in & added since this update on November 15th:
- Ballroom Blitz has had an MCOM station and headphones added to it, whereas pre-patch it was the only map with neither
- The spawn locations of many headphones on most maps has changed
- The above Morse message plays on loop until the MCOM station eventually explodes, although this appears to be buggy and thus the station will not always behave in this way
- Once the MCOM station explodes, headphones stop spawning on the map
- Dying after having retrieved a headphone will no longer cause a new headphone to spawn at the initial spawn location of the one the dead player was carrying
- Only one pair of headphones will spawn upon the initiation of a round on each map
February 14, 2017
On February 14, the Morse code changed again, to the following message:
GO STRAIGHT TO <location_name>. OLD METHODS COMPROMISED. MUST ACQUIRE NEW KEY. WILL MISS DROPOFF IF DELAY OR INCORRECT LOCATION.
Each user hears a different location name. It is currently unknown which factors determine who hears which location, or if locations are simply randomly assigned to players. Additionally, APREMONT must be swapped with VARENNES due to an error on the developer's part. Here is the list of the 26 locations so far, along with the maps the locations refer to, in alphabetical order:
ABBEY MAP APREMONT: Ballroom Blitz (SwapAPREMONTwithVARENNES, which is near Ballroom Blitz)APREMONT RITZ BED: Ballroom BlitzAMIENS NEUF FURNITURE: AmiensBUCKET MARSHLANDS FAW: FAO Fortress (Al-Faw is translated to "Fao" from Arabic)CANAL KANTARA VASES: Suez CanalCASTELLO ISLE ADRIATIC: Empire Edge (Empire Edge is on the Adriatic Coast)CHURCH RUINS AMIENS: AmiensCOASTAL FORTRESS ADRIATIC: Empire EdgeCRATE JABAL JIFAR: Sinai Desert (El-Jifar is close to Sinai Desert)CRATE SEREN VENETIAN: Monte Grappa (Monte Grappa is in Venice)CRATE TRENCH CANAL: Suez CanalFERRO FIRE VENETIAN: Monte GrappaHILL BARN ADRIATIC: Empire EdgeHILL TOWER CANAL: Suez CanalHOTEL CHECK PERONNE: St. Quentin Scar (Peronne is close to SQ Scar)LONGUEVILLE STATUE AMIENS: AmiensLUGGAGE BASEMENT VARENNES: Argonne Forest (SwapVARENNESwithAPREMONT, which is near Argonne Forest)OUTPOST BARREL FAW: FAO FortressPANEL WATER VARENNES: Argonne ForestPILLAR OUTSKIRTS JIFAR: Sinai DesertRUIN VENTURE PERONNE: St. Quentin ScarSTATUES GARDEN APREMONT: Ballroom BlitzSTOVE TURRET VENETIAN: Monte GrappaTRAVECY ATTIC PERONNE: St. Quentin ScarTREE FORTRESS FAW: FAO FortressTREE TRAIN VARENNES: Argonne Forest
The message will repeat until you move away from the MCOM station, at which point the MCOM will explode. Each of the locations mentioned above seems to have the same symbol near it.
Symbols

The symbols discovered at each location are difficult to find; they are small double arrows pointing to the left and right, and only appear when the player comes within 0.4 meters. Additionally, players can only see the symbol at the location they've been "assigned" to. When examining a symbol up close, a distinct sound is played (video). Here are the symbols that have been discovered thus far:
-
ABBEY MAP APREMONT
Near wall of ballroom in Ballroom Blitz -
CRATE SEREN VENETIAN
On wall by crates on Monte Grappa -
BUCKET MARSHLANDS FAW
Rock near bucket on FAO Fortress -
HILL TOWER CANAL
On ruin wall on Suez Canal -
HOTEL CHECK PERONNE
By stairs in hotel on SQ Scar -
LONGUEVILLE STATUE AMIENS
Under bushes near statue in Amiens -
LUGGAGE BASEMENT VARENNES

PILLAR OUTSKIRTS JIFAR
Pillar on Sinai Desert -
STATUES GARDEN VARENNES
Wall of garden on Varennes -
VARENNES SERVANT BED
On windowsill on Ballroom Blitz
Second Message

VARENNES SERVANT BED locationAfter a player discovers their symbol, returning to an MCOM station with headphones yields the following message in Morse code, starting with one of the above location names, but reversed:
<reversed_location_name> REMEMBER FIRST RULE# IF COMPROMISED. L PILL.
Additionally, the MCOM's lights glow yellow instead of the usual white when broadcasting this message. An L. PILL is short for lethal pill, a pill intended to be taken by soldiers to commit suicide rather than be tortured. Visiting the specified reversed location, the second location, yields a triangle symbol in place of the normal double-arrow symbol.
Third Message

After a player discovers the triangle symbol at their second location, returning to an MCOM station with headphones yields another message:
<atbash_cipher> SECOND RULE. SIGHTING. REPORT AND WAIT. INVESTIGATING ALONE COULD LEAD TO DEATH
This time, the MCOM lights glow purple. Solving the Atbash cipher in the message yields another location from the list above. Visiting the third location leads to an arrow symbol pointing right.
Fourth Message
Returning to an MCOM station after discovering the third symbol yields yet another message. This time, the MCOM lights glow green (previously, they glowed white, yellow, and purple for the first, second, and third messages respectively). Here's the text of the message:
<rot_cipher) THIRD RULE. IF TAKEN BY THE OTHERS DISCOVER MEANS TO COMMUNICATE TO HOUSE
Solving the ROT cipher with a key of 7 yields another location from the list of locations, presumably leading to a fourth symbol.
This investigation is still in development, and this page will be updated accordingly as new leads emerge.
