Build Quality
Phonak Audéo Sphere Ultra have an excellent build quality with a robust, portable charging case and a high ingress rating of IP68.
Pure MaX have an impressive build quality, featuring a top-of-the-line IP68 ingress rating. I also found their portable charging case robust, though on the larger size.
Battery
Ultra is designed to deliver all-day use, with battery-life figures of up to 56 hours under ideal conditions (i.e., in quiet with no streaming) and about 10-11 hours when Sphere mode is continuously engaged. They take 3 to 4 hours to recharge, and a 30-minute quick charge can provide an additional 6 hours of use.
Pure Max hearing aids have a reported battery life of around 30 hours per charge. While less than Signia's previous Pure C&G device, it is still plenty to get you through the day. Recharging takes 3 to 4 hours which can be done overnight while you sleep.

Signia's app stands out with its user-friendly interface and modern, appealing design. It includes practical features like the ability to control the focus of your hearing aids and a mask mode to enhance speech clarity. Additionally, the app offers wellness features, utilizing hearing aid motion sensors for activity tracking.
Comfort
Phonak Audéo Sphere Infinio Ultra were extremely comfortable and lightweight in my ears. In general, hearing care providers can make numerous physical changes to prescription hearing aids to improve comfort.
I found MaX very comfortable due to their shape and earwire design. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit before you leave the office.
Design
Phonak's new Audéo Sphere Infinio Ultra model shares the same notably larger size as the original Phonak Infinio Sphere. This is needed for its increased AI processing. While the larger size may be more noticeable, Sphere Ultra remains comfortable, and your provider should have no trouble adjusting the fit to your preference.
MaX features a modern, sleek design and is available in a variety of colors, from discreet to bold. This latest generation has a rougher matt finish, which is nice.
Value
Phonak Sphere Infinio Ultra has a value score of 3.5/5 based on lab performance and public display price.
Signia Pure Charge&Go MaX has a value score of 4.7/5 based on lab performance and public display price.
Handling
Infinio Ultra are easy to use and adjust using either the large multi-function button or MyPhonak app. I had no issues making adjustments with either.
I did not run into any issues while using MaX hearing aids. They are very easy to use once setup by your hearing care provider. First-time users may need some practice to get accustomed to inserting the receiver-in-ear style properly.
Pro Support
Prescription hearing aids like Infinio Sphere Ultra are fit by hearing care providers so you should receive quality care. The MyPhonak app also opens the possibility for remote programming and virtual follow-up appointments.
