Sennheiser CX 400BT true wireless earbuds boast deep bass

Audio company Sennheiser has introduced a new pair of true wireless earbuds called the CX 400BT, ones that offer ‘exceptional sound quality,’ deep bass, and more, according to the company. The CX 400BT follows the company’s previously released MOMENTUM true wireless earbuds, this time around offering high fidelity, noise reduction, and more.
True wireless earbuds are, of course, the earpieces without a cable tethering them together. Sennheiser says it made the CX 400BT model for users who have ‘fast-paced, always-on’ lifestyles. Among other things, users can expect seven hours of run time from the earbuds per charge, plus another 20 hours of playback time using the model’s charging case.
As well, the CX 400BT feature built-in microphones with noise reduction for taking calls and accessing assistants like Siri. Sennheiser promises ‘crystal clear’ audio from its latest model, which likewise has customizable touch controls so the user can interact with them in a way that feels most natural.
The earbuds support Android and iOS, as well as codecs like aptX, SBC, and AAC. Digging into the specs, it seems Sennheiser packed 7mm dynamic drivers into the CX 400BT, the same ones found in the MOMENTUM True Wireless 2 model from the same company. The design is described as minimalist; customers can get them in white and black color options, plus they come with four size adapters.
The CX 400BT work with Sennheiser’s Smart Control app, which enables users to adjust the audio to their own tastes using the equalizer. However, Sennheiser says users are ensured ‘detailed treble’ and ‘natural mids’ straight out of the box — in addition to that deep bass, of course. The new model hits shelves on September 15 for $199.95 USD.

Jeep’s Wild Wrangler Magneto 3.0 Concept EV Is Going Out With A Bang

To go with that, Jeep has added Dynatrac 60 front axles (5.38:1 ratio) and Dynatrac 80 rear axles (5.38:1 ratio), along with 20-inch off-road beadlock wheels and 40-inch mud terrain tires. The whole thing is lifted by three inches compared to a standard Wrangler. The result, the automaker says, is an EV that excels in off-road situations, not least because of how controllable the power delivery is.
“When you’re rock crawling, you need to be very neat and clean with your driving,” Mike Allen, Jeep Design Chief, says, “especially if there’s a cliff next to you, you need to be very controlled with that.”
To help, Jeep has added a power selection switch. On the one hand, you can have the maximum 650 horsepower and 900 lb-ft of torque; alternatively, the standard setting tamps it down to a more conservative 285 horsepower and 273 lb-ft. Allen says the range is around 150 miles, though that — nor charging times —was never meant to be the Magneto concept’s focus.

The Best Mods & Upgrades That Can Give New Life To A C4 Corvette

Replacing your restrictive and likely corroded factory exhaust with a new cat-back exhaust is one of the best power adders that you can do to your C4 Corvette. The term “cat-back” refers to the section of the system that is downstream of the catalytic converter, a device that removes harmful emissions from exhaust gases.
An aftermarket exhaust with modern muffler technology will reduce backpressure, allowing more air to flow into the engine, which increases horsepower. According to the popular aftermarket exhaust manufacturer Corsa, a cat-back system for the L98 engine (the most common C4 engine) adds 14 horsepower and 16 foot-pounds of torque to an otherwise stock powerplant — all while adding a deep, muscular exhaust note that’ll make your C4 sound like a Corvette should.
Returning to catalytic converters for a moment, they’re typically long-lasting but may eventually fail by becoming contaminated, clogged, or overheated, leading to decreased horsepower. In the process of installing a cat-back exhaust, it’s worth inspecting or proactively replacing the catalytic converter itself. High-flow performance converters are available which will boost horsepower beyond the cat-back exhaust alone, yet still keep your vehicle compliant with the emissions guidelines of the EPA and local authorities.

6 Easy Ways To Unlock Your Android Phone Without A Password

For years, fingerprints have been the de-facto phone unlock method because of the method’s incredible convenience and relative security. While a bad actor can, in theory, replicate your fingerprint, and while some Android phones have had fingerprint reader bugs, the majority of the time it’s secure enough to trust while allowing you to access your device in less than a second.
Many modern Android phones utilize an under-display fingerprint sensor that uses either an optical light sensor or ultrasonics to analyze registered fingerprints, while others place a trusty capacitive sensor on the back of the phone or the power button.
Importantly, optical sensors are the easiest of the three to fool in the event someone gets access to your fingerprint. Law enforcement can be especially aggressive should they invent a reason to search your device, having once tried to use a dead man’s finger to do so. However, Android stores fingerprint data in a Trusted Execution Environment, an encrypted section of the phone’s memory that cannot be accessed by the main CPU or by apps.
Setting your fingerprints up can be a bit of a hassle, as some Android phones can be finicky. It may be a good idea to register the same fingerprint twice if you find that your phone’s fingerprint sensor has a hard time recognizing your preferred digit.
