If you want a professional wireless headset for all-day calls with serious range and battery life, choose Amazon Renewed Jabra Engage 65; if you need an affordable desktop speaker system with a built-in mic and headphone jack, choose kstime Computer Speakers.
• Amazon Renewed Jabra Engage 65 — biggest strength: DECT wireless freedom with up to 150 meters of range, 13 hours of talk time, active noise cancellation, and a fast charge to 40% in 30 minutes.
• Amazon Renewed Jabra Engage 65 — biggest trade-off: It is a voice-first headset, not a music speaker, and as a renewed item it carries a 90-day limited warranty rather than a full new-product warranty.
• kstime Computer Speakers — biggest strength: A complete desktop audio package — 14W RMS stereo sound, a 15° tilted design, Bluetooth 5.4, a built-in mic, and a front headphone jack, all in a compact 1.4 lb unit.
• kstime Computer Speakers — biggest trade-off: Wired USB power plus optional AUX or Bluetooth, and the brand notes it is not compatible with TVs.
• Who each pick is for: The Jabra is for people who live on calls and want to walk around while talking. The kstime is for people who want one small device to handle music, video, and the occasional call from a desk.
The Engage 65 Flex is built around one job: keeping you on the phone for hours without discomfort or a dead battery. It uses DECT wireless, which is a business-grade connection standard, and it delivers a range of up to 150 meters — that is roughly 490 feet. You can leave your desk, walk to another room, and keep talking. For anyone who has paced a hallway during a long call, that number matters more than almost any spec sheet detail.
Battery life is the other headline. Up to 13 hours of talk time on one charge, with a fast charge that gets you to 40% in half an hour and a full charge in 90 minutes. The headset also packs active noise cancellation, a dynamic driver covering 20 Hz to 20,000 Hz, and intuitive on-headset controls for answering, ending, muting, and volume. It is certified for Skype for Business Open Office environments, which tells you it was designed for noisy, shared professional spaces.
kstime Computer Speakers: Who It's For
The kstime st300 is a different animal entirely. It is a compact pair of desktop speakers — 6.4 inches tall, 3.1 inches wide and deep, weighing 1.4 lbs — designed to sit beside a monitor and fill a small room with sound. Dual 52mm full-range drivers push 14W RMS, and a curved bass reflex port adds low-end punch without the muddiness you get from sealed budget speakers.
The 15° rear tilt is a genuinely thoughtful touch. Instead of firing sound straight forward into your desk, the speakers angle upward toward your ears, which reduces reflections off the desktop and widens the soundstage. If you have ever wondered why cheap upright speakers sound thin, that geometry is a big part of the answer.
What makes it relevant to this comparison is the built-in microphone and the front-facing headphone jack. You can take calls or join chats through the speaker's mic, then plug in headphones for private listening without reaching around the back of your PC. Bluetooth 5.4 covers wireless playback from a phone or laptop, and USB power plus AUX input covers the wired route. One caveat from the manufacturer: when using Bluetooth with a PC, connect USB for power only and don't also plug in the 3.5mm cable, or you may get no sound or dropouts. It is also not compatible with TVs.
Who should buy it? Students, home-office workers, and casual users who want music, video, and light calling from one small footprint. Who should skip it? Anyone whose day is dominated by long professional calls — a speakerphone in a shared or noisy space will not match a headset with active noise cancellation.

In my opinion, the right pick comes down to what your computer is actually for. If your day is calls — real ones, hours of them — I would buy the Amazon Renewed Jabra Engage 65. The 150-meter range, 13-hour battery, and active noise cancellation are exactly what a heavy caller needs, and nothing in the kstime's design is built to compete with that. If your computer is a media hub first and a phone second, I would buy the kstime Computer Speakers. You get stereo sound, a mic, a headphone jack, and Bluetooth in one small package. Buy the Jabra for your voice; buy the kstime for your ears.
how to use headphones with mic on pc without splitter
You need a single TRRS connection rather than two separate plugs. The kstime Computer Speakers sidestep the problem entirely with a front headphone jack and built-in mic, while the Jabra Engage 65 connects wirelessly over DECT, so no splitter is required for either. If you are using a wired headset with separate mic and headphone plugs, a TRRS-to-dual-TRS adapter is the usual fix.
how to use headphones with mic on pc
Plug in, then tell Windows which device to use. Open your sound settings, set the headset as both the output and the input device, and check the mic level in the recording tab. The Jabra Engage 65 handles this wirelessly once paired, and the kstime's built-in mic works the same way once the speakers are connected by USB.
how to get headphones with mic to work on pc
Start with the physical connection, then check software. Confirm the device shows up under playback and recording devices, set it as default, and make sure the app you are calling from has the right mic selected. For the kstime in Bluetooth mode, connect USB for power only and don't also attach the 3.5mm cable — running both at once can cause no sound or dropouts.
what is the best computer headset with microphone
In my opinion, "best" depends on whether you are calling or listening. For call-heavy work, the Amazon Renewed Jabra Engage 65 stands out with active noise cancellation, 13 hours of talk time, and up to 150 meters of wireless range. For desk media with occasional calls, the kstime Computer Speakers offer 14W stereo sound, a built-in mic, and a headphone jack in one compact unit.
