I bought an ethernet cable - similar size - off . I think i spent  on it and it was an absolute joke. The rubber casing which protects the wires inside got cut open when it got trapped under the door and it stopped working. ...SO i looked on amazon and found this one which was slightly pricey but strong enough to last for a while and protect the wire from getting damaged.
I wear hear plugs at night which allows me to sleep with peace and quite in a noisy house. BUT in the morning everyone complains about how I don't get up to my alarm clock and they usually turn my alarm off or unplugg it.
To solve this problem I bought this alarm clock which I put on vibrate only. The vibrator wakes me up in the morning without making a sound and doesn't annoy anyone or wake them up early.
