The annual Consumer Electronics Show is now in the books, and AppleInsider offers a summary of some of the best Apple-compatible accessories we spied on the show floor on the third and final day in Las Vegas, including Lightning-connected headphones, more home automation accessories, and even a smart plant sensor.

Lightning headphones

While a number of Lightning-connected headphones were shown off at this year's CES, one of the first options ever announced is the Philips Fidelio M2L model. We had a chance to check out the headphones on the CES show floor, where Philips was showcasing the M2L's 24-bit DAC and on-board amplifier.

Audio is transmitted to the $320 Fidelio M2L over an Apple-certified Lightning cable that provides better sound than the analog audio taken straight from an iPhone's headphone jack.

The M2L's user interface is minimalist, with a single rocker-style switch handling music playback and volume controls. Inside, 40mm drivers sit behind plush ear cups, delivering powerful, clean sound.

Philips also announced the $299 Fidelio NC1L on-ears headphones this week, featuring active noise cancelation powered by the Lightning connection, though the accessory was not shown off in-person at CES. JBL also launched the $149 Reflect Aware in-ear headphones designed for athletes, complete with a "rugged, sweat-proof design."

Smart homes take center stage

Connected homes were a major theme at this year's CES, and AppleInsider met with a number of vendors on day three, showcasing the future of smart home technology. One of the more interesting lineups comes from Pella Windows and Doors, which is launching its new Insynctive family of products.

The retrofit sensor adapters allow for remote monitoring and control of accessories such as locks, doors, windows, window shades, and garage doors. When connected to the Insynctive Bridge, they can be controlled through iOS-compatible applications, such as Wink.

Pella Insynctive will become available on Jan. 19, and pricing will run $50 for two sensors, and $80 for the connected bridge that ties everything together.

Elgato was also at CDS 2015 showing off its new smart home ecosystem dubbed Eve. Products included door and window sensors, an electricity usage tracker and controller, and temperature and air quality sensors for rooms and general weather.

Finally, Lucis NuBryte is a cloud-connected smart home console that features automated lighting and security features. The control panel cleverly replaces existing room light switches, offering advanced home monitoring and control without an elaborate installation process.

Parrot's diverse showings feature CarPlay, plant watering

Finally, AppleInsider also swung by Parrot's CES booth on the third and final day of the show, where we had a chance to check out the company's diverse range of products compatible with Apple's iOS ecosystem. Of note was its new RNB6 CarPlay-enabled head unit, a forthcoming infotainment system.

The RNB6 features multi-source audio, a built-in equalizer, and supports Android Auto in addition to Apple's CarPlay. The head unit is set to launch by the end of 2015, but pricing has not yet been announced.

Parrot also showed off its second-generation H2O plant sensor. The connected device can measure soil moisture, temperature, sunlight, fertilizer and more. It also boasts a built-in irrigation system that automatically waters plants at different times of the day based on environmental factors, minimizing waste.
