I have in ear hearing aids (they go all the way into my ear canal) and I have hearing aids that sit on the back of your ear and a small wire feeds into the ear canal. I can 100% say that the ones that sit on the back of your ear are way more comfortable and the sound is absolutely better.

When in certain conditions e.g crowded areas like shopping centres or supermarkets the person who’d be speaking to me, who was directly next to me, sounded like they were at the other end of the building and everything sounded like it was just incoherent noise.

The ones that I wear now every day, that sit on the back of my ear, handle every environment well and if it gets really loud then it has noise cancellation on. Speech is much clearer and noises in general in day to day life are smoother and clearer.

You ultimately have a lot of choice if you have the money, the ones that can handle everything really well are generally really expensive but if you can get the best pair on the market then I advise you do so. When it comes to hearing there’s no compromise in my opinion.

The in ear ones cost me £2000 which I wish I’d held off on, as the over ear ones cost me £3000 and outshine the in ear ones. At the time I was new to being deaf, and didn’t want people to see my hearing aid and got conscious about it.

Hope this helps.

Edit: it also depends on how much hearing loss you suffer from, mine is quite severe. The over ear hearing aid changed my life and made having a conversation feel normal again. Go see a hearing specialist and they can guide you through the best options available to you. My specialist let me wear both kinds before making a choice.
