Replace Bluetooth Headset Battery

Bought the headset about a month ago, needed a replacement for my JBL Quantum 200's. Overall the product is top tier, the sound quality is crisp, clean, and (often times) very loud. Pros: - Long battery life (while wireless), in my experience it gets a solid 30-32 hours whilst connected to the included dongle, and right around 43 hours with Bluetooth only. The headset can be connected via Bluetooth AND the dongle at the same time. Note; I do have the RGB function disabled on my headset, which extends the battery life by a *ton*. - Good range on the wireless connection, both Bluetooth and dongle. - Capability to be wired with USB-C (console), or 3.5mm jack going into a headphone/mic splitter (PC) - Amazing mic quality *while connect via wires*. Honestly the mic's balance and quality is on par with some dedicated desk/boom mic's that I've had in the past. - Very comfy fit, I can easily wear them for 5-6 hours straight with no issues. Very little wiggle on my head, even when vigorously shaking or bobbing my head. - Active noise cancelling is so good that it's almost disorienting. Being able to hear most of the environment around you just vanish really is a harrowing and alien experience after never having used it before. The noise cancelling is togglable from a button on the left earphone. There is also a Talk through function, for when you need to hear everything around you or carry on a conversation. - Audio has next to zero delay whilst wireless. I've played quite a few CS:GO and Valorant games, relying almost entirely upon audio cues/footsteps. Not once did I notice any delay that ever affected gameplay. Con(s): - Uhm... Mic quality whilst wireless decreases substantially? Less of a con, more of a side effect to ANY wireless connection. Over all; If I could give this headset a 6/5 stars, I would. It really is one of the most versatile pieces of tech that I own.

this works to connect my PC with bluetooth headset

I purchased this to replace an older Plantronics headset with a failing, no longer supported battery. The CS540 lasts all day and has a far greater range than the one it replaced. It is a little difficult to find the right and most comfortable ear gel piece but I can wear it all day and not have a problem.

I use this Bluetooth headset for everyday use and workouts. Very comfortable and flexible to take everywhere with you.

Best bluetooth headset that I have had so far. I've gone through two sony headsets in the past few months and these are by far the best I've come across.

There will replace my field headset. Good quality.

Headset works great, easy to pair and battery seems to last a while. Great headset and price is right.

The two things that I appreciate the most are, 1. 3xcellent sound quality and, 2. It's refreshing for my ears to be able to breathe while talking on a Bluetooth headset.

Love the reception and my surroundings keeps me very aware what's going on around me. Totally a upgrade from my other Bluetooth headset

I bought it to replace my old Bluetooth speaker and it's a vast improvement
