Can you reduce the delay?

I was classically trained on piano and string bass and taught myself other instruments. I’ve continued to play and compose as a hobby all my life. I recently have experienced hearing loss due to Meniere’s that makes it difficult to hear pitch when playing. I tried Listen mode with AirPods but the delay is too long. I downloaded the app and purchased the equalizer hoping there would be no delay. It’s much less but still too much for playing and singing while composing.

This app with wired headphones works for conversation since the delay is tolerable. AirPods don’t due to the delay. The delay is tolerable when listening but I have to take the AirPods off whenever I talk, then put them back on to listen. I guess that’s why it’s called Listen mode! That’s OK for certain meetings, or a lecture, or maybe a concert - but not conversation where you are talking. Of course you have to use wired earbuds or headphones.

Thank you for your review! So sorry to hear about your hearing loss. We definitely recommend you always use wired headphones with Hear Boost. The AirPods are Bluetooth which as a technology has a delay when using live. We’ll work on reducing the latency! 😊

The reason I rated this five stars is because as a person who has difficulty hearing upper range sounds I could not hear the birds singing in the morning. If I listen real carefully I can barely hear them on my own but most of the time I can not hear them. I’m living in Arizona at the moment and every morning the The birds are singing back-and-forth to each other.

With the voice filter on I’m able to silence much of the background noise and I can clearly hear the birds singing. It’s amazing. I decided to test it on whispering which I cannot hear whispers. I hear a person whispering but it all mushes together. However with this app I clearly can hear the softest whisper and it’s just as amazing.

I’ve already purchased unlimited use and I’m thinking about purchasing the equalizer also. I don’t understand the benefit of the different rooms so I think I won’t buy that since the way it is right now seems to be working for me very well. Thanks for a great product.

What An Amazing Tool, Ignore the Bad Reviews

Most of the bad reviews are complaints from people who:

Think the best things in life should be free.
(Seriously, for this powerful app $12USD is definitely worth it)

Have no patience to honor the app as they are too lazy do trial & error and play with the different values.

I have no audio equalizer experience and it was confusing at first. But after sitting there fine tuning to sounds in and out - it’s astonishing of how well you can tune incoming vibrations of sound coming from far away.

Must used wired headphones. Now if you connect phone via Bluetooth to another device to a speaker and then plug in headphones to that.. that works too.

ANY Bluetooth device (regardless if it’s high end or not… will have latency issues with any specific app, console game , whatever. That’s BLUETOOTH. So don’t blame the app.

Be wise, use patience and $12 for the full range of this app I believe is a steal.

Or you can go online and find your own listening device for $30 and it doesn’t come with a recorder, and it’s not as discreet as simply holding your iPhone.

Support the app and developers. The completely free version worked well, and I wanted it all. The spaces are a cool edition and can really, really help deafen unwanted background noise while listening.
