Update // : Observation reports that SCP-1089-5 is no longer 
M H  butis instead an unknown female. It is not known when 
or how this change ocurred but Foundation agents are in the 
process of investigating the new SCP-1089-5/2. 


Update / / :Newspapers have confirmed M H was 
murdered between the time he was last observed and the first time 
the new female SCP-1089-5/2 was observed. 


Update // :SCP-1089-5/2 has been identifiedasH P ,a 
wealthy heiress living in . Observation to continue as 
scheduled. 


[DATA EXPUNGED] 


Update // :As expected, SCP-1089-5/17 was also reported 
murdered. Investigation into identity of SCP-1089-5/18 has begun. 
Observation to continue as scheduled. 


Addendum 1089: Testing of SCP-1089 is to be immediately halted 
and SCP-1089-4 immediately terminated per instructions from O5- : 


Instructions from O5- 


Effective immediately, discontinue use of 
SCP-1089-p while on site. 


That channel 5 changed without action from us 
suggests there are more goggles and 
channels are shared among them. 


We don't know who has been watching but 
since / / we've given them crystal clear 
surveillance of the inside of our secure facility 
as wellas SCP- |! 


Kill the link to channel 4 and continue 
observation of the other channels. Channel 4 
is now to remain blank and channel 5 is 
designated as your new primary observation. 


Disciplinary action to follow.

SCP-1090: Cordless Headphones 


Item #: SCP-1090 
Object Class: Safe 


Special Containment Procedures: The item is currently kept in a 
generic headphone case and can be safely stored alongside 
similarly contained items. Storage near non-anomalous listening- 
devices is not recommended. The item may only be removed for 
approved testing. 


Description: SCP-1090 has the appearance of a set of cordless 
headphones. Two irregularly shaped, highly polished stones 
(superficially resembling black basalt) are attached in place of 
conventional earpieces. The headband is white, with flexible joints 
allowing for size adjustment. A blue dot marked with a white "L" and 
a red dot marked with a white "R" are visible on the swivel joints at 
either end, presumably indicating "left" and "right". 


It is unclear how the stones have been fused to the rest of the 
device, and both headband and earpieces have proven resistant to 
conventional cutting tools. Results from radiography of the object 
have been inconclusive. 


When a subject places SCP-1090 over the ears in the fashion of 
conventional headphones, they report hearing music or distinctive 
sounds. This "music" ranges from simple melodies to paranormal 
auditory experiences. The device has no anomalous effect on 
individuals who simply touch or handle it; reports indicate that the 
stones remain oddly cool to the touch. 


Testing suggests that the longer an individual is exposed to 
SCP-1090, the more unusual and lasting the psychological and 
sensory after-effects. The upper-limit of exposure before permanent 
psychological and sensory damage has yet to be determined; new 
researchers are cautioned to increase the time of exposure by no 


more than seconds (see Dr. Rhys for a proposed algorithm). 


As the sounds reported are so far unique to the subject wearing the 
device, researchers are encouraged to review Experiment Logs 
Series 1 for details.

Note: Series 1 Logs describe the initial series of 
experiments conducted by Dr.S___. For ongoing 
experiments, and data contributed by other researchers,

Subject/s: D-Class female; age 22 
Procedure: Subject seated in a sound-proof 
room and instructed to place SCP-1090 over 
her ears, removing it when signalled by a red 
light. 

Duration: Two minutes. 

Results: 


Subject looked surprised upon placing the 
device over her ears, but made no attempt to 
remove it. She appeared to be focusing 
intently, and failed to react to the flashing red 
light until ten additional seconds had passed. 
Subject seemed ill-at-ease when questioned 
about the experience; possibly simple 
nervousness. 


Subject described clear and pervasive music, 
which seemed to “be playing before | put them 
on... it sounded like the middle of the song.” 
The “song” was described as a children’s 
choir, singing in a foreign language. “/t was 
probably, like, Asian or something. Kind of 
creepy, actually.”

Subject/s: D-0886 (male; 38), D-0423 (male; 
24), D-1002 (female; 31), and junior 
researcher M 

Procedure: Each subject seated in a sound- 
proof room and instructed to place SCP-1090 
over his/her ears, removing it when signalled 
by a red light. In the case of D-1002, a loud 
bell tone was substituted for the light. 
Duration: Two minutes. 

Results: 


D-0886: Reported hearing guitars playing 
several melodies at once. “Weird shit. Like 
Hendrix in a fucking mirror house.” 


D-0423: Heard a low sustained note, “Like a 
stringed bass’, followed by a melody he 
described as a poor bass solo. “But... played 
badly on purpose, you know?’ Subject seemed 
fixated on this idea, and would have prolonged 
the interview for several hours to explain 
himself. 


D-1002: Though subject had been informed 
that a tone would sound to signal the end of 
the test, she was unresponsive to the sound, 
despite its loud volume. After an additional 
fifteen seconds, the red light was flashed, and 
she removed the device. Subject appeared 
dazed, and did not respond to questioning until 
nearly fifteen minutes had passed. 


Subject eventually reported: “/ think it was my 
cat... it sounded just like my cat. He was 
singing a song to me. About fish.” 


Note: As none of the subjects testing 
the item have been physically 
harmed, we've given M_ permission

Subject/s: Dr. S 

Procedure: As of 2/03/ , the D-Class subjects 
of previous tests have shown no immediate or 
cumulative signs of injury. Dr. S 

volunteered herself as a test subject, and the 
original experiment was replicated without 
incident. 

Duration: Two minutes 

Results: 


Subject reported a low, sustained drone for the 
first thirty seconds, which slowly increased in 
volume. This was reportedly accompanied by 
a sense of expectancy— "Like something 
important was about to happen". The subject 
expressed doubt that she would have removed 
the device in those first seconds, even if 
instructed to do so. She described the droning 
sound eventually diverging into a series of 
random notes, resembling electronic music. 


"It was like normal music, | guess... with 
distinct notes and pauses. But it's hard to 
describe the sound of— no, | wouldn't really 
call it dread. | know dread, okay? It felt a little 
unsettling, like | wasn't supposed to be 
listening in... but at the same time, | knew if | 
kept listening... | don't know. I'm being vague." 


Dr.S reported than the "music" faded into 
silence, immediately before the two minute 
light flashed. She has expressed interest in 
repeating the experiment.

Subject/s: D- ([REDACTED)), D-2101 
(male; 22), D-4040 (male; 56) 

Procedure: Subject is seated in a room (not 
sound-proof) and instructed to place the object 
over their ears; flashing red light signals 
removal. 

Duration: Eight minutes 

Results: 


D- : After the first two minutes, the subject 
was seen to raise both hands and press them 
over the earpieces. The subject's description 
of the [REDACTED]. 


D-2101: Subject displayed a reaction similar to 
D-1002, failing to respond to the flashing light 
for nearly three minutes, and remaining in a 
complacent and insensible state for close to an 
hour after the test's conclusion. Subject 
reported hearing "wind-chimes", not localized 
in the earpieces, but "some really close, and 
some really far away... too far away to hear. 
There must have been hundreds of them." 


D-4040: Subject displayed growing unease 
while wearing the device, and removed it 
promptly when the light flashed. When asked 
to describe his experience, subject refused to 
say more than, "/t was brown." 


Addendum: D-_ was recently terminated 
while [REDACTED]. An overseeing agent 
alerted us that, ten hours before recorded time 
of death, D- made several requests to use 
SCP-1090. When this request was denied, D- 
displayed considerable emotional distress. 


Addendum 02/08/ : Both D-2101 and D-4040 
have reported nearly identical symptoms to 


research personnel; it must be noted that 
neither subject has been allowed contact with 
the other since the end of their respective 
tests. Both report that the "music" they heard 
while wearing SCP-1090 has been playing 
continuously "in their heads". Unlike normal 
instances of cognitive itch, they claim the 
sounds are changing, and growing 
progressively louder. 


Note: As the primary psychiatric consultant for 
this research team, it is my request that no 
further experimentation take place until a "safe 
range" of exposure is determined. -Dr. Rhys 


UPDATE 02/24/ 


A series of experiments to determine the "safe 
range" of exposure to SCP-1090 were 
performed over the course of one week, 
achieving consistent results when replicated. 
Six (6) minutes and thirty (80) seconds has 
been established as the "safe range" of 
exposure, with a buffer of approximately 
twenty seconds. All D-class personnel involved 
in testing have been placed under thirty-day 
observation; scheduled terminations 
postponed as necessary. 


Addendum: D-2101 and D-4040, subjects of 
preceding experiments, continued to complain 
of "loud music"; both were observed to have 
trouble sleeping, and spoke loudly in 
interviews, as if compensating for poor 
hearing. All subjects of the Safe Range tests 
who were exposed to the device for more than 
seven minutes have since reported nearly 
identical symptoms. 


Addendum: D-4040 was found deceased 
after a violent altercation with D-3 ; witness 


accounts, while their reliability is questionable, 
all made some reference to D-4040's 
symptoms. All similarly-afflicted subjects have 
been restricted from D-class common areas.

SCP-1091: Digital Mode Shortwave Entity 


Item #: SCP-1091 
Object Class: Euclid 


Special Containment Procedures: SCP-1091-1 is not to be 
removed from its containment room. The containment room is to be 
surrounded by a multi-stage Faraday cage. Three armed security 
personnel are to be stationed outside the containment room at all 
times. No radio devices are permitted within 200 meters of 
SCP-1091-1. 


A live microphone feed must be active in the containment room, 
outside the Faraday cage to record any transmissions or sounds 
from SCP-1091-1 for later analysis. SCP-1091-1 is not to have radio 
contact with any radio transmitting/receiving device unless approved 
by Level-4 Personnel for controlled testing purposes. Personnel are 
not permitted contact with SCP-1091-1 without specific 
authorization. All personnel must be searched to find and remove 
any radio devices before contact with SCP-1091-1 is permitted. 


If SCP-1091-1 transfers to another radio transmitting device, all 
personnel are instructed to seek out and destroy all radio devices 
within a 5 km radius. Should Foundation personnel be unable to 
locate and recover SCP-1091 within two hours, refer to Recall 
Protocol 1091-Beta. 


Description: SCP-1091 is a sentient entity that resides in radio 
receiving and transmitting devices. If its host device possesses a 
microphone (or shortwave reception equipment) and speakers, 
SCP-1091 is capable of communicating. 


SCP-1091 is capable of transferring itself between hosts by radio 
signal, at a range dependent on the broadcast power of its host 
device. Given the opportunity, it will use its ability to transfer 
between devices rapidly in an attempt to [DATA EXPUNGED]. 


SCP-1091 must not be allowed to reach its destination. Should such 
a scenario become a possibility, MTF Lambda-W is to refer to Recall 
Protocol 1091-Alpha. 


Thus far, SCP-1091 has not demonstrated an ability to infect 
multiple devices simultaneously. However, this possibility cannot be 
entirely discounted. 


If the host of SCP-1091 is destroyed or otherwise rendered unable 
to transmit before it is able to transfer, SCP-1091 will immediately 
become located in SCP-1091-1, regardless of distance. For this 
reason, it has been suggested that SCP-1091-1 is the original 
source of SCP-1091. 


SCP-1091-1 resembles a model S-38 shortwave receiver, 
manufactured by the Hallicrafters company in the mid-1940s. 
However, the composite material comprising the outer shell of 
SCP-1091-1 appears to be a mixture of carbon fiber and an 
unidentified material. Additionally, all attempts at opening 
SCP-1091-1 for examination have failed. 


All attempts to tune SCP-1091-1 have been ineffective. SCP-1091-1 
plays only static until SCP-1091 initiates communication. Any other 
radio device within 500 meters of SCP-1091-1 will experience the 
same tuning failure. SCP-1091 is able to communicate with 
Foundation Personnel through various types of "Digital Mode" 
broadcasts. The choice of digital mode appears to be related to the 
person it is communicating with and the subject matter of the 
conversation. 


Interview Log 1091-a 
Interviewed: SCP-1091 
Interviewer: Researcher 


Researcher : SCP-1091. Clearly, you have some 
form of sentience. Tell me, what is it that you were 
planning when we had recovered you? 


(SCP-1091 is silent for several seconds, before 


broadcasting a data burst transmission approximately 45 
seconds in length.) 


Researcher : Run that through the software, | want 
to know what this thing is thinking. 


It was later determined that the transmission was an SSTV 
broadcast, in mode "Robot36". Decoded image is listed below 
available audio clip of interview.

SCP-1092: A Species of Fish 


Item #: SCP-1092 
Object Class: Euclid 


Special Containment Procedures: SCP-1092 is to be housed ina 
5 by 5 by 2.5 meter cell that is completely watertight and is capable 
of being filled and drained via an installed pumping system. During 
its parasitic stage, SCP-1092 will be contained in one (1) domestic 
pig of no less than 54 kg. During this phase, SCP-1092's host is to 
be fed regularly and otherwise treated as a normal animal. After two 
(2) months time since initiation of the parasitic stage, the 
containment cell will be flooded with 40 cm of water and SCP-1092 
will be allowed to enter its aquatic stage. The body of its former host 
will be incinerated. After four (4) months, another domestic pig 
meeting the same specifications will be placed into the inundated 
cell. Upon successful infection, the water will be drained and boiled 
three (3) times at no less than 200°C before being disposed of. 


All individuals who experience direct contact will SCP-1092 or its 
containment area will be analyzed with X-ray radiography after 
leaving in light of Incident A, personnel suspected of exposure to 
SCP-1092 will be quarantined for no less than two (2) weeks, during 
which time they will receive full body X-ray scans every 48 hours. 
Those infected will be monitored until SCP-1092 exits its parasitic 
phase terminated (see Addendum 1092-02).
