Signia Pure Nx Reviews
Hearing aid reviews are fundamentally different from reviews for most other consumer electronic products. The reason is because individual factors, like degree of hearing loss, have a profound effect one's success and overall satisfaction with the product. When purchasing a hearing aid, you'll need to consider more than just your hearing outcome ... Continue reading

Overall Ratings
Hearing Tracker uses a ten-question survey to assess consumer feedback on hearing aids. The percentage bars below reflect the average ratings provided per question, averaged across all hearing aids belonging to this family of devices.
Note: Original answers provided in star rating format.

Constant cutting off for no reason. Wire gets stretched. I am on the 3rd set since January. First was broke since day one. Second amplifier broke.
Current one is 3rd set and all it does is cut off for no reason..no loud sounds when it happens. I'll yawn and it'll kick off

Ive worn top of the line Siemens CIC HA for 20 years, the Pure NX is my 3rd pair.
After wearing a loaner pair for 2 months I had to have these. From its phone app, blue tooth streaming, sound quality, directional control, comfort, I cant begin to list all I like - but my fav is streaming music while having a conversation.
I streamed music 10 hours one day and after a 12 - 13 hr day, still had battery life.
Going from a CIC to behind the ear is very remarkable in terms of comfort. Also with the CIC I constanly had to reach up and change channels until I could find one that best met my environment at the time. With Pure I may have to increase the volume 2 - 4 times a day as it does takes care of the rest.

Hard for me to gauge but speech sound clarity didn't seem as sharp as the Phonak Marvels I had trialed earlier. However it is great with not driving me crazy with background noise. The ball-shaped attachment for the domes is great for getting a comfortable angle sitting in the ear canal, however that limits you to their one option of dome shape (which can be open or closed and different sizes, but they are all the same shape and material) and are not interchangeable with any other brand. They're fairly comfortable but I am very very sensitive and would have liked more options for the material of the domes. I have the streamline bluetooth device and I find that it works very well - expensive add-on and something else to charge and carry around, as opposed to Phonak that connects directly from the hearing aid, but at least the function is good and it's fairly compact. So... I kind of wish I had stayed with Phonak (I switched because of the background ambient noise issues) but there are definitely advantages with this one too, especially if you're not super sensitive to domes and especially if you use iOS devices that work with the bluetooth.
















How much was the pair ?

I have Signia 312Nx7 since autumn 2018. I have IPhone 7 At the beginning my Hearing Aid worked fine - even myControl app. I liked it very much. Then suddenly in December the Voice Active Tracking stopped. It happened at the same time as new version of Control app was taken into use.
The problem has been tried to solve by every possible ways, but any kind reason have been found. The importer in Finland has not got any answer from Sivantos, but they have not helped us
Has anybody Elise have same kind of problems with Voice Active Tracking
Yes trialing them now there are problems, with big chunks of days missing on the data log. I really want to like these but the BT connection is sketchy.
I have recently purchased a Purecharge and go nx 7 and a Cros Pure 312 nx for single sided hearing. I am experiencing my aids shutting off for no reason. Usually they don’t shut completely off, but are at such a low level of amplification, I can’t hear anything. Have had Signia change them out for new ones, but still happening. I’d love to make these aids work!
2nd week of a trial 312 NX7 I want to love these but the BT connection is intermittant.
The BT connection is needed for the Activity Tracking but the APP does not need to be open, the phone must be in range 30' or less.
Powered up the aid 2 times and one aid did not connect to the phone and showed 0 Battery life . Turned BT on and off to fix. Possibly there may not be activity showing if the aids were not actively functioning in a quiet environment .
It appears all aid manufacturers have intermittent BT in common.
Read their various reviews on the Apple APP stores, eg Widex, Phonak, Oticon etc.
