How to pair multiple bluetooth headphones to a single windows pc and reduce audio lag

Buying a refurbished Samsung Galaxy S24 can be a smart way to get flagship performance without the flagship price—I've done it more than once when testing phones for Wcetesting Co. But “refurbished” covers a wide range of realities: dealer-refurbished with new parts and warranty, manufacturer-certified returns, or a phone that was lightly repaired and resold by a marketplace seller. To avoid ending up with hidden hardware problems, here's...

I set out to answer a simple but consequential question: can the Raspberry Pi 5 handle 4K transcoding for a home Plex server? After spending a week building a Pi 5 Plex test rig, pushing it with different source files and client scenarios, and measuring CPU, temperature, and playback behavior, I have practical findings to share. I'll walk you through what I tested, what worked (and what didn't), and how the Pi 5 fits into realistic home media...

Keeping a mixed Zigbee and Z‑Wave smart home healthy means keeping firmware up to date — but doing that manually across dozens of devices is a chore I actively avoid. Over the years I’ve tested setups on Home Assistant, Hubitat, SmartThings and a couple of vendor hubs, and I’ve learned a few practical patterns for safely enabling automatic firmware updates without bricking battery‑powered sensors or losing automations at the worst...

I test a lot of laptops and tablets at Wcetesting Co, and one recurring theme I keep coming back to is batteries. Modern devices use lithium-ion (or lithium-polymer) cells that are incredibly energy-dense but also sensitive to how you treat them. Over the years I've developed practical routines that help me get more useful life — both day-to-day runtime and long-term cycle longevity — out of devices from Apple, Dell, Lenovo, Samsung and...

I plan a lot of content — reviews, how-tos, and trend pieces — and over time I built a practical workflow that combines Notion as my single source of truth for ideas and editorial calendars with ChatGPT as a creative and execution engine. This system saves me hours each week, keeps the pipeline full, and makes it easy to hand off drafts or task lists to a collaborator. Below I’ll walk you through the exact setup I use, the automations I...

When I go for long runs in cold, windy weather or push a tempo session up a steep trail, I want two things from my wearable: reliable heart-rate data I can trust in the moment, and SpO2 readings that actually mean something instead of being a noisy number that changes every minute. Over the years I’ve tested watches and straps in the lab and the field, and I’ve learned that the “most accurate” device depends on what you value most —...

I spent the last two weeks living with both the Google Pixel Tablet and the iPad Pro M4 to answer the question I keep seeing in inboxes and comment threads: which is better for drawing, note-taking, and—critically—battery life in real-world use? I tested both devices side-by-side with the same workflows I use daily: sketching longform concepts, annotating PDFs in meetings, and running mixed use (video calls, streaming, web browsing) to...

Why I care about offline-first smart home hubsI’m always testing gear with a practical question in mind: can this product do the useful stuff reliably when the internet drops out? For me, privacy and resilience go hand in hand — I want automations that run locally, sensors that report to my Home Assistant instance even if the cloud is down, and voice or remote control that doesn’t leak data. Over the years I’ve moved from cloud-first...

Switching from the Apple ecosystem to Android felt like a small leap and a mini migration project the first time I did it. I remember juggling cables, cloud accounts and the nagging fear of losing years of messages and photos. Over several moves I've refined a repeatable process that keeps things intact — or at least gives you working equivalents quickly — so you can get on with using your new phone instead of noodling over what's missing....

I've spent a lot of time testing smart cameras across brands, and one of the most common — and frustrating — issues people bring to me is the Google Nest camera showing a black screen. I’ve seen this crop up during lab-style tests and in real homes: sometimes it’s a simple connectivity hiccup, sometimes a power problem, and sometimes firmware or app settings are the culprit. In this troubleshooting guide I’ll walk you through practical...
