Jabra PRO 920 Mono wireless headset for desk phone

BATTERY LIFE - I've been on call for most of the workday. I've been using this headset 3-5 times a week for several hours at a time with no issues for about a month. Many days, I've been on the phone for over 8 hours but probably never had the headset on for more than 5-5.5 (hours) without at least 30 minutes on the charger while on a break. At this point I Can't speak to long-term use of the device, but initial battery performance has been fantastic! COMFORT - One of the most comfortable headphones I've ever worn. Some may prefer dual earbuds, but I actually prefer ones with just one. Although I usually place it on the same ear, I can easily switch from side to side if needed. SOUND QUALITY - The sound is clear and crisp and the headphones have a great range! I can go anywhere in my house, yard and to the mailbox with no degradation or interruption in sound or audio quality. EASE OF USE - All I had to do was plug it in and my conf call program recognized it automatically - no special setup or configuration required. The headset itself has an easy mute button to be located directly on the earpiece, which is ideal if you're walking around. (I tend to pace when I think!). Volume controls are also on the headphones, although I must admit I never seem touch the one I want the first time. PORTABILITY - It breaks down fairly easily and fits in the original box with a little patience, but I don't think this is the case designed for travel and I'm afraid that separating the headset and the assembly does not eventually prove to be problematic or damaged in transit.MISC - One thing that may be annoying to some is that when muted there is an intermittent "tone" sounding. I think I've gotten so used to it that I can't even hear it now. On the one hand, it might be annoying if you were concentrating on it; on the other hand, it serves as a reminder that the mute is on. The cradle clearly indicates when you're muted, but you can't tell by the headphones alone - a small on-light indicator would be a nice addition for the future. SUMMARY - I'm very happy with the purchase and the price was reasonable. It's a great little helmet and I've recommended it to my peers. In fact, I like it so much I'm considering buying one second to leave in my alternate office, so I don't need to keep taking this one apart. However, even with a reasonable price, it may just not be a tax-wise choice for the time to buy a second one. ***July 2019 Update*** 16 months (give or take) since my first review and I'm back to backing the first 5 stars I gave it overall. I'm really, really impressed with the battery life and durability of this headset. It's been much more reliable in terms of sound quality and trickle charge compared to the much more expensive headset at work. And I find that much more comfortable! As I stated in my first review, I spend several hours a day on the phone and it jams throughout. Still very happy with my purchase and I know the sound quality on my end is good , because others asked for it when they were on the market. I always recommend!
