I did already in another thread. I liked the sound quality and “natural directionality,” but in certain quiet or very loud listening situations speech discrimination was a little tough.
I also didn’t like the size or how they fit and felt behind my ear compared to the Pulse (the Azure was a 13 battery, the Pulse a 312), the battery door was a pain in the butt to use, and the Azure was susceptible to perspiration problems. Every couple of days one or the other battery would shut down, causing me to think they were draining batteries. They weren’t, but the battery door was letting perspiration in, and the perspiration was getting in the battery airholes and temporarily killing the batteries.
It took me a couple of weeks to figure out what was going on, but I finally figured it out. It always occurred within 30 minutes after I’d finished up at the gym and showered, but was still perspiring more than normal, particularly my head and hair behind the ears.
Those issues all combined and the extra cost over perfectly acceptable Pulse’s with rechargeable batteries and the charger led me to keep the Pulse’s and return the Azure’s. The Pulse’s also have better wind noise management than the Azure’s, and have never shut down from perspiration under the exact same circumstances.
The Azure had a “warmer” quality to the sound, whereas the Pulse has a “brighter” quality to the sound. I also had every confidence that in critical listening situations I’d be certain to hear speech, and didn’t have that same confidence in very quiet or very loud settings with the Azure.
EDIT: Also, the Pulse was designed from the start as an open-fit BTE, and the thin tube snaps on and off a small metal post on the aid, making it easy to remove to clean and reattach. The Azure is a regular BTE that uses a conversion kit to convert the ear hook to use open-fit thin tubes, but they screw into the hook. Even with my reasonably good manual dexterity, twisting off the tin tube, then reattaching and twisting it back on was a royal pain.
