Long lasting and good sounding headphones are a match made in heaven! Just about everybody who owns a pair of wireless headphones wants longer battery life and better sound, and that's exactly what you get with the Edifier W855BT headphones.
The W855BT earpads and headband are covered by soft leather-like material with a fluffy cushioning made of a soft, springy foam that feels extremely nice on the skin.
You can easily wear the Edifier W855BT headphones for a few hours without discomfort partly because of the flexible clamping force of the headband and the breathable inner sides of the earpads.
Being wireless headphones, the Edifier W855BT over ear headphones have the audio playback controls built-in to the right earcup as opposed to in-line on the cord like you get with most wired headphones.
Both earcups have a little play, allowing those with odd-shape heads to get a better, more comfortable fit around the ears.

What's also nice about the Edifier W855BT is the audio playback design which is pretty unique because it has the design of a vinyl phonograph record (including the record grooves).
Instead of raised finger buttons that you press, the W855BT headphones has push buttons built inside the vinyl record earcup. The only raised button that you see on the headphones is the off/on/bluetooth pair button which isn't actually a button but a switch.
The off/on/pair button has an interesting and unique "slider switch" design that operates two ways. It operates from the "off" position to the "on" position and viceversa like a regular slider switch and from the "on" position to the "bluetooth pair" position like a "flicker" switch that flicks back and forth to trigger bluetooth pairing.
The small inner circle with the triangle and two bars symbols is actually a push-button that operates the playing and pausing of audio. It also contains the NFC chip area where you place an NFC-enabled phone right beside it to connect via Near-field communication (NFC).
NFC is a pretty cool bit of technology that uses electromagnetic induction to make the pairing connection between the phone and the Edifier W855BT headphones. Compared to Bluetooth connectivity, NFC connectivity is even faster taking literary two seconds to connect without having to go into the bluetooth settings of the phone to manually make the connection.
Volume up and volume down are operated by pushing down the outer ring of the vinyl record at the 9-hour mark (volume down) and 3-hour mark (volume down). The Edifier W855BT have a 98dB sensitivity so these headphones can be turned up very loud, which is nice.
Next to the off/on/pair slider switch, you find the 3.5mm headphone socket, the micro usb charging port and the microphone pinhole for hands-free calling.
To answer, reject or hang a call you use the play/pause button. You can mute the microphone and transfer a call to mobile and headset back and forth, as well as redial the last number.

Speaking of the W855BT microphone, it has a rangy pickup pattern with high volume gain so call quality is loud and clear although there is no noise cancellation integration to drown out background noises.
Charging time takes a reasonable 3 hours (via 5V/0.5A) which is pretty good considering the built-in lithium-ion rechargeable battery can hold charge for 18 hours of use at 70 per-cent volume. While charging is taking place, the status led lights up red and then turns off when full charge is complete.
Being low impedance headphones (32 ohms), the Edifier W855BT can be driven very easily to high fidelity from a smartphone.
The Edifier W855BT can be used in wired mode via the included audio cable and micro usb charging/data cable so you can hook them up to a usb port of a computer to listen to music.
The usb audio mode is a rather unique feature on wireless headphones so it's neat that it was added to the Edifier W855BT headphones.
The headband frame and adjustable slider are made from aluminium-magnesium alloy, making the Edifier W855BT over ear headphones even lighter in weight than using pure metal.
The total weight is 238 grams, making the Edifier W855BT headphones fairly lightweight
(as light as the Zte Axon M smartphone).
A lush clamshell zipper case is bundled to store the Edifier W855BT headphones during transportation. The case has Edifier branding with a nice quality feel to it.

Being that nature is the mother of all inventions, it's not surprising to find technology modeled after animals! From the frog looks of the Porsche 911 sports car to the Tenikle 2 tripod, which is a flexible tripod with a starfish body and octopus tentacles.
Tripods comes in all shapes and sizes, and with different types of construction, namely solid aluminum, ball-and-socket plastic joints and pliable metal like in the case of the Tenikle 2 tripod.
The tripod market is really a crowded one and already established so it's nice that Tenikle 2 pushes the envelope by reinventing the standard ball-and-socket joint design with a clever and more functional eye-catchy tripod contraption.
The Tenikle 2 tripod can be rolled up and stored in a trouser pocket thanks to its bendable arm legs that give the Tenikle 2 a wide range of operations.
However, it's the addition of octopus-like tentacle suction cups that really sets the Tenikle 2 apart from other bendable tripods because it allows the Tenikle 2 to be even more versatile than a standard flexible tripod.
Each Tenikle 2 tentacle features three suction cups as well as a suction cup at the cross center of the Tenikle 2 food-grade silicone body where the tripod thread is also mounted. The Tenikle 2 tripod has a total of 10 suction cups which allow the Tenikle 2 tripod to be stuck to any suction-friendly surface.
Even better, the Tenikle 2 suction cups also double as holders for holding glass back phones like the iPhone X.
Saying this, like with any suction cups the suction effect is not ever lasting. The Tenikle 2 suction cups suction effect lasts around 5 minutes with dry cups and a bit longer if you moist the suction cups slightly.
While the suction effect is taking place, the Tenikle 2 suction cups do a good job at retaining securely the iPhone X glass back although for safety it's probably best to use the Tenikle 2 phone suction only for selfies, macro photography or as a desk phone holder.
For aerial shots or run-and-gun photography, it's best to use the include accessories that come with the Tenikle 2 which include a 1/4-20" adapter, a smartphone holder tripod adapter and a GoPro tripod adapter.
Compared to ball-and-socket joint tripods, the Tenikle 2 tripod is more reassuring because you don't have to worry about joints popping out from their sockets.
The only caveat though with flexible bendable tripods like the Tenikle 2 is that the pliable metal inner frame will eventually snap after being bent many times over.
Each Tenikle 2 tentacle measures 5 inches in length so when bent the Tenikle 2 can provide a maximum height of 4 inches approximately.
There is no mention on the website what type of pliable metal compound the Tinikle uses for its frame wire so it's not clear whether Tenikle 2 uses nitinol wire combined with a different shape-memory alloy.
One thing for sure though is that the Tenikle 2 legs are very sturdy and can support quite a bit of weight (up to 6.8 kg)
Another accessory that is included with Tenikle 2 is iTag, a bluetooth 4.0 remote shutter portable selfie clicker that doubles also as an anti-lost/ anti-theft alarm tracker. The addition of iTag is a thoughtful touch as iTag can be used also as a key/item finder.
iTag comes with its own mobile app, cTracing app, with cool features like Radar tracking letting you see in "feet" how far or how close iTag is from your phone.

For a more accurate location, the cTracing app also lets you track iTag via Google maps or Baidu maps.

Like with all new things, there is always a learning curve and keyboards are no different especially split ergonomic keyboards such as the Perixx Periboard-512. The typing experience on an ergonomic keyboard is rather unique and the Periboard 512 is no different particularly if you are used to typing on PC keyboards with standard layouts.

After a few hours of typing, you surprisingly get used to the Periboard-512 ergonomic keyboard fairly quickly. It helps also that the keys are tactile as they provide a more comfortable typing experience.
The Perixx Periboard-512 is a membrane keyboard so it uses membrane keyboard key switches which are not as loud as mechanical key switches. If low typing sound volume is a requirement for you, the Periboard-512 is right up your alley.
Even if you are a hunt-and-peck typist who uses two fingers to type, you will like typing on the Periboard-512 membrane keyboard because the thuds as you hit the keys don't resound nearly as much as, say, a blue switch mechanical keyboard.
The shortcut multimedia hotkeys are a nice touch. You get a total of seven shortcut buttons including Internet browser (www) shortcut key, Search shortcut key, Open e-mail shortcut key, PC sleep mode shortcut key, volume up and volume down shortcut keys and mute shortcut key to instantly mute your PC speakers.
While the Perixx Periboard-512 shortcut buttons are made for Windows computers and there is no dedicated Mac command key for Mac users, the Perixx Periboard-512 Windows "Winkey" key can be used as the Mac command key.
The Windows command key is the key with the Windows logo, between the Ctrl and Alt keys. To use the Windows command key on a Mac computer using the Perixx Periboard-512 you simply press the Windows key followed by C, X or V to copy, cut and paste. On a Windows computer, you would press the usual Ctrl+C, Ctrl+X, or Ctrl+V to copy, cut, and paste.
The Perixx Periboard-512 keyboard works with old and new Windows operating systems, namely Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10. While there is no mention on the user guide that the Periboard-512 keyboard supports Mac computers the Periboard-512 keyboard does work with Mac computers.
In fact, any USB keyboard will work on a Mac. The only issue with using a PC keyboard like the Perixx Periboard-512 with a Mac computer is the placement of the Mac Command key which will be different from what you're used to.
If you're tech savvy though you can place the Command key just left of the space bar on the Periboard-512 by remapping the keys from System preferences from the Apple menu bar. From there you simply swap the control and command key functions.
While membrane keyboard keys tend go a bit mushy over time, membrane keyboards are more reliable because membrane switches do last longer.
Membrane keyboards are definitely a better investment than mechanical keyboards and three times cheaper in price. If you aren't looking to be doing much gaming, the Perixx Periboard-512 is perfect for an every day ergonomic typing experience.

Beneath the shortcut hotkeys, you find the Num Lock, Caps Lock and Scroll Lock led status indicators. Many keyboards don't usually have the status leds placed next to the keys they represent and while the Perixx Periboard-512 doesn't either the Num Lock, Caps Lock and Scroll Lock status leds are at least adequately labelled for any user to know which one is which.
On the bottom of the Perixx Periboard-512, you find three rubber feet and two leg stands to raise the keyboard. The rubber-sleeved USB cable is 1.80 meters long.
The Periboard-512 keyboard is constructed with hard resin (Polystyrene), silicone rubber and thermoplastic (ABS) so it's durable and fairly lightweight weighing a little over one kilogram. The dimensions of the Periboard-512 are 48.5cm long, 23.6cm wide and 4.4cm high.
There is a non-removable palm wrist rest on the Perixx Periboard-512 3 dimensional keyboard that provides some support on the wrists which is nice but the palm rest is not cushioned. Cushioned wrist rests tend to be better at reducing fatigue and preventing carpal tunnel syndrome although that's a bit of debate according to whom you ask.
Most people agree though that a wrist rest is not substitute for proper typing technique which should be typing with straight wrists while the wrists are hovering over the keyboard.
