Audio-Technica Wireless Earbuds Offer High Performance And Style

The audio world and mobile world have been coming together by virtue of shared technologies.

One recent example that continues to trend are wireless earbuds. Once considered a ‘low fi’ alternative to audiophile ear covering headphones, high bit rate digital files and improved bluetooth protocols have opened the doorway to mobile hi-fidelity. Case in point: Audio-Technica SONICSPORT Model ATH-SPORT7TW and Model ATH-CKR7TW.

ATH-CKR7TW

When you take a moment to search what others are saying about these models you quickly realize everyone is impressed with their audio performance. Personal devices are highly subjective. Some of us prefer touch sensitive controls but others like physical micro-switch controls. If you are in the former read on and learn what these earbuds have to offer. With the exception of noise-cancellation technology, they are loaded with features.

The sound

In general terms both models sound about the same- that’s because they each have large diaphragms (a larger 11mm driver for the CKR7TW), superb DAC digital to analog converter circuitry and robust headphone amplifiers. The CKR7TW goes one step further by supporting both AAC codec (a high quality form of audio signal that can exist in various bit rates and frequencies making it a near audiophile format) and Qualcomm aptX (a low latency, super high quality bluetooth format that allows for audiophile 24 bit signal playback over bluetooth). Since the ATHSPORT7TW is designed for outdoor and active use (such as gymnasium or jogging in the rain) it makes sense that the aptX format is not included. After all, a noisy city street or busy country road is not the ideal place for long periods of scrutinized listening.

For comparison we avoided the usual reviewer method of “A-B” testing using the same source and decided instead to stream various audiophile files and test signals from YouTube- both in AAC and aptX. In our opinion a lot of this becomes a process of splitting hairs since high frequency AAC sounds about the same as low frequency aptX.

What matters most is the fact that both sets of earbuds get the job done and sound great.

The looks and comfort

Both models come with 4 sizes of Ear tips to help you get the perfect fit. The ATHSPORT7TW also includes 4 sizes of Ear fins and Ear tips that have trademarked Sweatguard technology. If you haven’t guess already, the sport model is also sweat and water resistant with a IPX5 rating. That means full on high powered splashing of water won’t affect the model and that’s reassuring. Water is the absolute worse enemy of earbuds. The SONICSPORT ATHSPORT7TW looks very tasteful too- an all greyish-white colouring with a slightly subdued brand logo is anything but gaudy.

CKR7TW

Not to be outdone, the CKR7TW includes 3D loop support ensuring that long periods of listening are comfortable. We also slightly prefer the looks too- the brushed Rose gold accents paired with the grey coloring makes for a very attractive look and will have you standing out from the crowd.

Charging power a plenty

With all that high powered amplification and bluetooth functionality (Fully smart music controls and phone controls including a built-in microphone for answering calls) you’d be forgiven for thinking that these models are high drain on their battery. Would you believe 17 1/2 hours playback time (using the charging case) for the SONICSPORT and 15 hours playback time (using the charging case) for the CKR7TW? The charging case is almost jewelry box like in that it is beautifully designed and has a magnetic holding area that offers a very satisfying “click” when you insert the Ear buds for a charging session or for travel storage. Of course USB cables are also included if you prefer to charge from umbilical.

Phone use

Flawless. Crystal clear audio playback and a superb quality microphone. Not a single person we called complained about ‘echo voice’ or ‘long distance sound effects’.

Safety

Hardly ever mentioned in an Ear bud or headphone review is safety consideration and if you are a cyclist or jogger you know what I am talking about. The ability to hear audio cues from fast moving traffic or approaching vehicles is an essential part of safe outdoor exercise. The SONICSPORT alleviates this concern with a special pass-through circuit. This option can also be turned on to allow for listening of conversations.

Price

Just like in the automotive world, quality does not come cheap. Now that’s not to say that these models are prohibitively expensive, in fact, they are very competitively priced especially when compared to similar models from other manufacturers. With the Audio-Technica brand you know you are getting something special. The company has been an innovative player in recording studios and on stages worldwide for decades. That history and experience with both capturing and playing back sound is present here.
MSRP SONICSPORT ATH-SPORT7TW $200usd
ATH-CKR7TW $249usd. For the Silo, Jarrod Barker.

Dolby Laboratories Media Emulator In Minnetonka Master Suite

DolbyMediaScreenshots
MINNETONKA, Minn. — Minnetonka Audio Software Inc. (MASI), a leader in production software for motion picture, broadcast surround sound, and consumer electronics applications, recently announced that it is now providing worldwide distribution and resales of the Dolby(R) Media Emulator toolkit from California-based Dolby Laboratories Incorporated. This fortifies Minnetonka Audio’s already comprehensive offering of production problem solvers. Minnetonka Audio has added Dolby Media Emulator to its SurCode for Dolby E Master Suite 3 product bundle without raising the bundle price.

 “Our strategic decision to distribute Dolby Media Emulator strengthens our current product mix and expands our reach into more post suites,” said Jayson Tomlin, vice president of business operations at Minnetonka Audio. “For our customers, Dolby Media Emulator is a bargain in itself. By bundling it with the SurCode suite without raising the price, we’ve created a one-stop shop for media producers that is truly an outstanding value.”

Dolby Media Emulator is a software tool for authoring and post that provides real-time emulation for Dolby broadcast formats. Acting as a plug-in for popular digital audio workstations, Dolby Media Emulator enables an audio engineer to simulate accurately how content will sound when played back through licensed consumer electronics.

Dolby Media Emulator lets an operator preview the results of differing metadata values when decoding Dolby Digital, Dolby Digital Plus, and HE-AAC audio formats.

One application worth highlighting: Take a look at this diagram. See all of those speakers? Consider that Dolby Surround formats are varied but most include multiple speakers and therefore multiple positions of "sound". The vast majority of consumers are listening to complex surround signals through only one or two speakers. That means, a proper mix MUST take this into account. Minnetonka's Dolby Media Emulator makes sure you get this right. CP

“With the majority of surround programs being played back in stereo and mono environments, correct metadata and downmix settings are a critical requirement for deliverables,” said Markus Hintz, director of global sales and business development at Minnetonka Audio. “In addition to previewing their metadata settings, audio engineers can use Dolby Media Emulator for standardized loudness measurement, proper  monitoring of LtRt sources, and downmixes from all other sources.”

Rather than resort to using home audio gear in a professional workflow, engineers can use Dolby Media Emulator to validate mix and metadata decisions against a certified standard in their familiar monitoring environment.

To aid in specifying proper metadata values, Dolby Media Emulator can measure and properly determine the dialogue normalization (dialnorm) value with a standardized loudness meter. The included loudness meter supports international ITU-R BS.1770, ITU-R BS.1770-2, and EBU R-128 loudness standards and incorporates the optional Dolby Dialogue Intelligence(TM) algorithm. Its ability to configure and control the monitoring environment and evaluate metadata parameters makes Dolby Media Emulator an essential product for postproduction, DVD, and DTV facilities that master, author, or broadcast program material with Dolby surround sound formats. Dolby Media Emulator runs as an Avid(R) Pro Tools(R) RTAS(R) plug-in, and as a VST(R) plug-in for popular programs such as Nuendo(R).

Dolby Media Emulator is available for immediate delivery from Minnetonka Audio resellers and distributors, and also directly from Minnetonka Audio’s eShop. In-depth information on Dolby Media Emulator and how it enriches existing tools and workflows is available at www.minnetonkaaudio.com
