Vizio P65-F1 4K UHD TV review: Vizio's P-Series deliver good brightness and HDR, but image glitches remain

This smart TV shines with HDR, but Vizio's new array backlighting is more prone to artifacts and there are holdover processing glitches from last year.

Marshall Kilburn II Bluetooth speaker review: Great sound and nostalgic design

You'll pay extra for the branding, but this is a strong and well-designed speaker, even it it isn't built by the company famous for its "Marshall stack."

Hisense H9E Plus 4K UHD TV review: Smooth action and good color, but it's not overly bright

The H9E Plus is the most affordable 120Hz TV we've seen, and the extra 60Hz do make for about the smoothest motion in its class. But HDR still doesn't pop as with some similarly-priced models.

Soundcast VGtx Bluetooth audio transmitter review

Though it's expensive, the Soundcast VGtx can broadcast Bluetooth for a moderately greater distance than the average transmitter. It also has an optical pass-through, which can be handy in home audio systems.

Edifier S2000 Pro review: Bluetooth speakers on a whole other level

The excellent-sounding S2000 Pro speakers have more in common with studio monitors than your average bookshelf or Bluetooth speaker. Top notch stuff at a very reasonable price.

Samsung Q9FN 4K UHD TV review: Top-tier goodness, now significantly more affordable

Samsung's Q9FN TV offers better blacks than last year's model, and is arguably the best TV on the market. The series is also a lot less expensive than it was last year.

Nuheara IQbuds Boost review: Fine tune and augment your hearing experience

These Bluetooth headphones sound great with music, and they can help compensate for minor hearing loss. Think of them as hearing aid lite.

Polk Audio Command Bar soundbar review: Good sound, with Alexa at your service

The Polk Audio Command Bar mixes well-balanced and beefy sound (the latter courtesy of the included subwoofer) and Amazon Alexa. It works, but Alexa can be recalcitrant when the bar is producing sound.

TASCAM 202MKVII dual cassette deck review: A high-quality, but pricey, tool for digitizing your tape collection

The Tascam 202 MK VII USB cassette deck is the best we've seen for digitizing audio cassettes (in good condition), but at $500, it's a very expensive option.

Aukey SK-S1 Bluetooth speaker review: Classy looks and sonic goodness (at least at low volume)

This pretty little near-field speaker will sound great on your desk, but it's not the right choice for parties or taking your tunes outdoors.

TCL 55R617 4K UHD Roku TV review: Great color and HDR for a very modest price

The 6-series' color and HDR are astounding for this price range, but weak motion handling and problematic backlighting remind you this isn't a high-end TV.

Bluesound Pulse Mini Bluetooth speaker review: Great sound, strong feature set, and a few rough edges

The Bluesound Pulse Mini sounds great, will mesh with other Bluesound speakers, and plays music from a wide variety of sources. But its out-of-box experience and controls leave something to be desired.

Will HDR kill your OLED TV?

With HDR requiring considerably more brightness from OLED elements, will lifespan be significantly reduced? Can OLED's reduced luminance over time still provide the HDR effect?

Samsung 65Q7FN 4K Ultra HD TV review: (Relatively) affordable quantum dot color

The Q7FN doesn't offer quite the brightness or HDR impact that Samsung's higher-end QLEDs deliver, but its picture is still marvelous and the "disappearing" design is arguably the best in the business.
