I have been using the Artone 3 MAX BT neckloop with my bilateral Med-El CIs for years! It is so awesome that I own several of them so one is always charged and ready. This is by far my most used piece of assistive tech. I have given a rating for each section out of 5 stars.

Wearing comfort:
This BT neckloop is so tiny and light! I do not even know I have it on. It can be worn under a shirt very discretely. It has a built-in clip to attach to shirts if desired. The loop itself is very thin and light as well. I have never worn a lighter neckloop!
COMFORT: 5 stars!

Battery life and charging:
The Artone 3 MAX is easy to charge. It comes with a USB cable. It took several hours to give it a full charge for the first use. A red light indicates it is charging and a blue light indicates that it is fully charged. The directions on the package state that the battery lasts for up to 4-5 hours of listening or up to 150 hours of standby time.
EASE OF CHARGING: 5 stars!
BATTERY LIFE: 4.5 stars!

Ease of use:
This neckloop has very easy to use button controls. There is a center button that is the main function/play/pause button. This center button is surrounded by four other buttons arranged in a circle. This includes + (increase volume), – (decrease volume) and back/forth buttons which allow us to move through playlists. Since these are actual buttons, rather than a touchscreen, the settings remain set even when we are active. Usability: 5 stars! Versatility: Pairing the Artone 3 MAX with BlueTooth devices is simple. We just activate BT on our device to be paired and then press & hold the center function button on the Artone 3 MAX until both a red and blue light start flashing. That’s it—we are synced and ready to listen!
EASE OF SYNCING: 5 stars!
VERSATILITY: 5 stars!

Distance:
The listening range of the Artone 3 MAX is listed as 10 meters, about 30 feet, in all directions. In my home I found I can pair it with my iPad and leave my iPad on the first floor while I move around the house. I can go both upstairs and downstairs and stay connected without any change in sound quality.
DISTANCE: 5 stars!

Sound Quality:
I use the Artone 3 MAX to listen to music, podcasts, audiobooks, TV, aural rehab apps and for phone use. The sound quality is great! There is no noticeable lag time when streaming directly from my BT devices to the neckloop. This is a huge plus for this neckloop. Sound clarity: 5 stars!
STREAMING: 5 stars!

Phone Compatibility:
It is easy to use the Artone 3 MAX with BT cellphones. After our phone is paired with the neckloop, incoming calls will connect automatically. To answer the call, we just press the center button. That’s it! We will hear the caller and they will hear us. There is an option to clip the Artone control unit to our collar which positions the internal mic closer to our mouth. If we select MT on both of our CIs, we will hear the phone audio on both sides. Terrific hands free calling!
PHONE USE: 5 stars!

Overall:
The Artone 3 MAX gives CI recipients a wireless listening option which connects to BT devices. Since it is so small and light, it will be comfortable for children as well but they may need to have the thin neckloop secured in some way as it is long. For bimodal cochlear implant recipients, the Artone 3 MAX can send audio to both the CI and hearing aid-as long as the hearing aid has an active telecoil.

An excellent BT neckloop!
