I napped on the subway with AirPods in—and the person next to me heard my alarm first

A seat was all it took to let my guard down

It was a little past the evening rush. I expected to stand, but someone in front of me got off and a seat opened up. The moment I settled my bag on my lap, my shoulders relaxed. At work I had imagined going home and catching up on chores. Now even getting home felt distant. After a late night and an afternoon staring at screens, I wanted to look at neither my phone nor the view outside.

I still had several stops to go. Usually I would watch a few short videos and find myself at my station. That day I could not even follow the opening sentence. I put the screen away and played gentle music through my AirPods. I knew roughly how long this familiar route took. An alarm a little before my stop seemed enough to let me close my eyes. I chose a time in the phone’s Clock app.

I did not separately check the earphone connection when setting the alarm. Music was already playing in my ears, which seemed like confirmation enough. The phone was on silent too. I normally kept message sounds to myself, and it never occurred to me that an alarm might behave differently. I checked the displayed time once more and laid the phone face down on my bag. That feeling of being ready came much too quickly.

The passenger beside me was reading a paperback. People stood quietly in front of us, holding the straps. Train noise and announcements filled the background, but nobody was making a loud sound. I adjusted my posture so my shoulder would not touch my neighbor. I thought about not leaning on anyone while asleep, but not about where my wake-up sound would go. My consideration stopped at falling asleep and left out waking up.

It took a few seconds to realize the alarm was mine

I do not think I had closed my eyes for long. A familiar melody reached me, and even in my dream I was searching for my phone. Had the music changed? Was somebody’s phone ringing farther away? It took a while to recognize my own alarm. Meanwhile, the person beside me shifted slightly. That movement opened my eyes first. Only then did I realize the melody was coming from the top of my bag.

Keeping a finger on the page, the passenger said quietly, “Your phone’s ringing.” I hurriedly turned it over. Still half asleep, I missed the button and could not silence the alarm at once. I held my bag with one hand and tapped the screen with the other while the sound continued. Why was it playing outside my earphones? Removing one AirPod made the phone speaker suddenly sound clearer.

I apologized. The passenger nodded and returned to the book; the person standing in front looked away too. It was not much of a scene. Still, I felt awkward raising my head afterward. An alarm meant to keep me from missing my stop had disturbed other people before waking me. Trying to be punctual, I had sat there for several seconds without even recognizing that the noise belonged to me.

There was still a little time before my stop. I could have closed my eyes again, but any sleepiness had vanished. Holding my phone, I kept checking the next station. I imagined my neighbor still thinking about the alarm, although the pages turned as normally as ever. A few seconds for everyone else filled the rest of my journey. Even taking off my shoes at home, I remembered the sound escaping despite my earphones.

Connecting AirPods did not make my iPhone alarm private

At home I tested a short alarm with the same setup: music through AirPods, phone on silent. When the time came, the phone sounded too. I had wondered whether the connection had briefly dropped on the train, but my expectation itself was wrong. Because music and calls went through my earphones, I had assumed alarms would follow. Listening to the actual output showed a distinction I had never checked.

Apple’s guide to the iPhone’s built-in Clock app explained that alarms play through both connected headphones and the built-in speaker. Silent mode does not mute those alarms either. I had used the music’s output route to predict the alarm’s, but they were different behaviors. This guidance concerns the iPhone’s built-in alarm; it does not establish how every other phone or alarm app works. That was why my own device-and-app combination needed checking.

Setting an alarm had not been the mistake. I still needed a way to remember when to get off. The missing step was checking whether the earphone alarm I wanted would actually play only through earphones. Searching for “AirPods alarm speaker” and “private subway alarm” finally made my question precise. Checking that something was connected and checking where the alarm sound went were separate tasks.

An earphone alarm did not make every nap worry-free either. An earphone could fall out, its battery could run low, or the expected arrival time could change. A signal sent only to my ears depended on that connection staying available. One successful short test was not a promise that I would always wake on every commute. Checking that day’s setup alongside the actual journey was more realistic.

Next time, I checked the sound before setting the time

Next time I checked the phone and earphone batteries before leaving work. I tested a short alarm to hear where it played: audible in my ears, without leaking through the phone, and behaving as expected with music playing and the screen locked. At first this seemed like extra trouble. Remembering those flushed seconds on the train made the comparison simple. Checking while awake was much easier.

I also stopped timing the alarm exactly from the usual journey length. Rather than waking immediately before my station, I left time to gather my bag and check the announcements. A crowded carriage could require extra time to reach the door too. If travel was delayed or the route changed, I reconsidered the plan. A signal that a chosen time had passed was not confirmation that the train had reached my station.

I kept the phone within easy reach instead of burying it in my bag. I sat so my bag would stay on my lap and rested in a way that let me check the surrounding information. If the seat was uncomfortable or I was too tired to trust a short rest, I did not force myself to sleep. A comfortable commute nap involved more than sound settings: it also meant deciding whether this was a suitable place and day to rest.

An earphone alarm such as Nenne was one option when I wanted a time signal just for me. I thought first about the scene on the train, rather than a feature list. Could I finish my break without disturbing someone else? Earphones falling out could mean missing the signal, so I tested my device first. For journeys where getting off on time mattered, I also prepared another way to check the time. One app was not my whole travel plan.

A perfectly ordinary exit, with nobody turning to look

A few days later I found a seat on a train at about the same time. I was tired again, but did not immediately switch off the screen. I checked the remaining journey and my prepared signal before closing my eyes. I do not know how deeply I slept. A sound I could recognize reached my ears, and I straightened up. My neighbor kept looking at their phone. Nobody had to move to wake me.

I checked the time and zipped my bag. After confirming the next station, I moved calmly toward the door. Those ordinary minutes were unlike the previous scramble. I removed one earphone to check the outside sounds and watched other passengers as I got off. I did not need a remarkable wake-up experience. Resting, moving on time, and not drawing another person into helping or being disturbed were enough.

Looking back, I had attached too much to “sleeping with earphones in”: private music, consideration for others, and an assumed private alarm. A small check could separate those things. Now I do not judge a new pair of earphones or a different alarm by a familiar-looking screen alone. Seeing a connection indicator and actually hearing the intended output are still separate checks.

There will be more days when I want a short subway nap. Finding a seat on a tiring commute will still make closing my eyes tempting. I would simply like fewer breaks to end with the passenger beside me giving the signal. Noticing my own alarm, gathering my bag, and getting off are ordinary steps. That passenger’s brief comment taught me to consider where the wake-up sound goes as carefully as how I fall asleep.

Questions about earphone alarms on the subway

Does an iPhone alarm play only through AirPods when they are connected?

The iPhone’s built-in Clock app also plays alarms through the phone’s speaker when headphones are connected. Hearing music through AirPods does not mean your alarm will stay private. You can check this behavior in Apple’s alarm guidance.

Can I rely entirely on an earphone alarm during a subway nap?

You may miss the signal if your earphones fall out or disconnect, and a time-based alarm does not detect your arrival station. Test your actual setup first and allow time to prepare for getting off. Recheck the expected timing if the journey changes.
