When i say, Its able to wake me up i can almost guarantee it gonna wake anyone else up that purchases one also! Its well worth the money! Before purchasing this i have always had the hardest time waking up with an alarm clock! I used to have to set several different alarms with several different sounds in hopes that one of them would wake me up but most times i wouldn't. I would sleep right through all of them because none of them were ever loud enough! THIS ONE HAS BEEN A GAME CHANGER FOR ME! I was surprised with how loud this one is and all the different options it has to choose from! All of which work amazingly well! It's actually able to wake me up the very first time it goes off each morning. What makes this one stand out even more is its not only loud but you can you choose different sounds along with being able to change the tone of each one of the sounds and also change the volume level of each one! Review: Very Loud - Seriously, if you're a deep sleeper, this alarm clock is a lifesaver! It's incredibly loud, like a small explosion going off, but in a good way. The different sound options are pretty cool too, and you can even adjust the tone. Plus, the custom snooze is a game-changer for those mornings when you need an extra few minutes. Definitely worth it if you're tired of sleeping through your alarm. ## Features - DESIGNED FOR HEAVY SLEEPERS & DEEP SLEEP - Built specifically for people who sleep through phone alarms and standard clocks.

I sleep like a rock - this is the only thing that will wake me up!! *by S***. on November 24, 2024* This Sharp Big Band Super Loud Alarm Clock - is the real deal. It isn't a normal loud, it is EXTREMELY LOUD! Which is exactly what I wanted and needed! It has different wake up sounds and has I think 1-15 different loud settings, 15 being the loudest. If your anything like myself (I would call myself a very, very, HARD sleeper, anything above "10" will work for me) but I still have it all the way up just so I know ill wake up regardless! It's a blessing and a curse to be able to sleep like I do, but the curse is that normal alarm clocks just don't do it! I even looked into those alarm clocks with a shaker for your pillow.. I can tell you with how loud this is, you don't need anything else but this alarm clock! To give you a little example of how deep of a sleeper I am, when my fiancé and myself were in the hospital after our third child, the fire alarm for the brand new hospital we were in, went off and everyone on our floor ran out of their room thinking if was for real, and this was around 3AM in the winter, there was snow on the ground outside - I was still sleeping on the bed completely unfazed from this gigantic alarm going off through the hospital. Yes I was a bit sleep deprived as well but still, even if I wasn't, I would not have woken up.. So after saying that type of story, and for me to say this works for me should tell you how loud this alarm clock is!! I will say if your sharing a house with roommates, small kids, or a family - you may want to let them hear it so they at least don't awaken frightfully when it goes off lol regardless where this alarm is located in your house, it WILL wake up people throughout the house if you have to have it on the loudest setting. My fiancé can literally wake up to her phone vibrating in the morning. She is a very light sleeper so if she was around in the morning to hear this alarm clock go off it would probably blow her eardrums out (lol being a little dramatic but it is extremely loud when your right next to it) but really this is so loud it will wake some up everyone in the house. In all seriousness this alarm clock does its job for HEAVY SLEEPERS and is a fantastic!! I have loved it since the first morning Ive used it. It has not let me down yet and I HIGHLY recommend this alarm clock to the people that sleep similarly to myself. 5 out of 5 stars for this product! Love it!! ## Frequently Bought Together - Sharp Big Bang Super Loud Alarm Clock for Heavy Sleepers, 6 Extremely Loud Wake Up Sounds: Rooster, Bugle, Nagging Mom, Jackhammer, Siren, Beep – Up to 115db Volume, Red/Black with Red LED Display - uscce Loud Dual Alarm Clock with Bed Shaker - 0-100% Dimmer, Vibrating Alarm Clock for Heavy Sleepers or Hearing Impaired, Easy to Set, USB Charging Port, Snooze, Battery Backup - Peakeep Loud Alarm Clock for Heavy Sleepers Adults, Metal 4 Inches Twin Bell Battery Operated Alarm Clocks for Bedrooms Decoration (Jewel Blue) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/475357976-big-bang-115db-alarm-clock-for-heavy-sleepers-dual-alarms](https://www.desertcart.sk/products/475357976-big-bang-115db-alarm-clock-for-heavy-sleepers-dual-alarms) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-10*
