Samson Q7 Review

 

 

We found the Samson Q7 to be as accurate as the over-priced Senneheiser MD431 II and at about 5 times the price, so we won't be able to recommend the Senneheiser desktop mic but the MD431 edged out the Q7 in noise cancellation. An even bigger surprise was that the Buddy Desktop USB microphone tied with the Samson Q7 in accuracy. At this point we decided to focus on comparing the Q7 to the Buddy Desktop since they're both desktop microphones. If you add a USB soundcard to the Q7, it will cost about the same as the Buddy Desktop which includes an integrated USB soundcard that begs the question: If both microphones are about the same price and feature the same accuracy, why carry both items. Read on...  

 

 

 Although both the Buddy Desktop and Q7 were dead even in accuracy, the Buddy Desktop has the advantage of being significantly smaller (low-profile), having a mute switch and includes a built-in USB soundcard. By contrast, the Q7 is a performing microphone which makes it a little more difficult to position because of the angle but the Q7 has its own advantages. We found absolutely no drop-off in accuracy when using the Q7 in a moderately quiet environment from 8 inches away but the big surprise was that you could actually maintain relatively high accuracy with the Q7 from as far away as 4 feet (that's no typo). The microphone even worked from as far away as 5 feet but dropped off at that point. By comparison, the Buddy Desktop works best, in a moderately quiet environment, from about 6 inches away and can be quite effective, in a very quiet environment, up to 14 inches but we don't recommend pushing the envelope quite that far. Another Q7 advantage is that it can optionally be goose neck mounted for specialized situations such as a powered wheelchair or bed rail.     In a desktop computer situation with plenty of space we would recommend the Samson Q7 because you can lean back in your chair and still get relatively high accuracy. We find it vastly preferable to any Voice Array microphone which we never recommend. In a small space situation or perhaps a notebook computer workstation situation, we would recommend the Buddy Desktop.  

 

 

 Note #1: The Q7 works best with 1/2 duplex pods such as those made by USB Pod and VXI. We do not recommend any Full Duplex USB Pods at this time.

 

 

Note #2: This microphone is not recommended for soft (quite) voices

Quiet.

Do all these mics work just as well with Vista's voice recognition?

eMicrophones introduced the Samson Q7 over a months ago. Click Here to read our experienced evaluation.

Mr. Knowbrainer claims you can use the Samson Q7 at great distances from one's mouth. eMicrophones has only been using and testing entertainer quality speech recognition microphones like the Sennheiser MD431I for 12 years. It has been our experience that the MD431II and the Samson Q7 only work optimally at close distances. This is because they both use a super cardiod (heart shaped) pickup pattern that is designed for use at 1/2 to 2 ". You can move further away, but accuracy suffers greatly. The highly respected former Dragon developer Chuck Runquist posted today on Mr. Knowbrainer's forum the following which confirms this. The message thread is titled, "Improved Accuracy Back to the Andrea USB pod and my Sennhesier MD431 II mic."

"Regardless of what anyone says about how far away from the microphone element you can be with either the Sennheiser MD431 II or the Samson Q7, the further you are away from the microphone element the greater the propensity for the "canyon" effect. They canyon effect is lower volume and the speaker sounding like they're further away from the input source. They canyon effect reduces accuracy. It's not so prevalent with the Sennheiser MD431 II, but you obviously pay for the quality of the Sennheiser MD431 II. However, the Samson Q7 is dramatically affected by the canyon effect, and I suspect that this is another reason why you're not getting the accuracy with the Samson Q7 that you can and should."

In addition, Dana Ciardi who started the thread on Mr. Knowbrainer's forum gave up on the Samson Q7 after trying to use it at great distances. She went back to her trusty Sennheiser MD431II with which she transcribes hundreds of pages of medical transcription every week.

First of all, when used at the correct distance of one half to 2 inches from one's mouth, it works fine with soft voices.

The Buddy Desktop, Buddy Gooseneck, Samson Q7 and Sennheiser MD431II work just as well in Vista's Windows Speech Recognition. On the page is for the Samson and Sennheiser linked in the previous sentence, you can see a movie of how they work on a Balanced Spring Microphone Arm. This allows you to work hands-free. The only thing you must realize with any of these microphones is that you cannot turn your head while dictating.

Although we can appreciate emicrophones 12 years of experience, it doesn't necessarily equate to necessarily knowing how to properly test microphones. We have been testing microphones since 1971 when we were making 4 track recordings of orchestras, jazz bands and rock bands. We owned and ran a professional recording studio, just off from Nashville's famous Music Row, from 1979 through the early 90s before becoming a third-party developer of DragonDictate, the predecessor to NaturallySpeaking. Our nearly 40 years of microphone testing paints a slightly different picture and while we respect emicrophones efforts, we have to disagree with their findings and their test methods.

 

#1 The Samson Q7 will NOT work with soft voices without the assistance of a pre-amp. The Q7 is low impedance and not designed to be used with a computer soundcard. They're designed to be used as performing microphones with hotter live mixing boards. When attempting to pass the Audio Setup Wizard the Q7 barely moves the blue bar down 1 notch with a fairly loud voice and you can’t get better evidence than what is right in your face. Standard headset microphones will typically move the blue bar below the 50% mark and often go much lower. All any end user has to do is run the Audio Setup Wizard to verify our findings. You cannot beat the math.

 

#2 According to emicrophones, their Q7 microphone only works “optimally at a close distance”. Our Q7 microphones work from as far away as 4 feet and we include a 30 day moneyback no restock fee customer satisfaction guarantee so perhaps we should let the customers decide :)

 

We additionally recommend purchasing Speech Recognition Microphones, Digital Recorders and NaturallySpeaking software/utilities from Nuance Gold Licensed vendors because this gives you an extra layer of Nuance Certified tech support.

 

Please also note that our KnowBrainer 2007 command software is now freely available to the physically disabled and any forum member who has contributed 2000 more postings. You'll find additional KnowBrainer information in our What is KnowBrainer.

Nonsense. When sound gets further from a microphone element the signal becomes weaker. A soft voice is weaker than a strong voice. Ergo, if you state it does not work with quiet/soft voices then it cannot work well as the distance increases. One cannot mutate or fabricate the laws of physics.

You are not the only person with a 30 day money back guarantee. Returns are inconvenient for the customer and reflect badly on the business that sells an item inappropriately . That is why a microphone expert would not recommend a microphone be used in a method that is likely to incur poor results.

#2 According to emicrophones, their Q7 microphone only works "optimally at a close distance".

eMicrophones Samson Q7 is the same microphone unless Samson is producing a Lunis Special version that has a weaker signal.

We understand you have a problem with our findings but our 30 day return policy removes any risk. We stand behind our findings and we really don't think people will have a major problem with our return policy which we introduced to the speech recognition community while embarrassing other microphone vendors who insisted on restock fees and a 15 day return policy.

 

If you understood how the now dated DNS 8 year old Audio Setup Wizard technology actually worked you would realize that all you have to do is speak a little louder when you run it initially to increase your noise cancellation and boost the signal but you're apparently unaware of this information or you would've mentioned it earlier. We're not telling you to sell your Q7 microphones and by all means feel free to guarantee that 6 inch or so range. Our customers will have a 4 foot guaranteed range. Enough said.

 

We don’t just sell microphones for every occasion. We ONLY sell speech recognition microphones, recorders and speech recognition software. Non-licensed Nuance vendors are not privy to the latest up to the minute information from Nuance development and level 1 premium tech support because they have no access to it and that is why we typically recommend purchasing Speech Recognition Microphones, Digital Recorders and NaturallySpeaking software/utilities from Nuance Gold Licensed vendors because this gives you an extra layer of Nuance Certified tech support.

Actually I understand a lot more than you think you know. In any event, Chuck Runquist who knows more than you (he has to correct your microphone and Dragon information constantly) and I put together has posted on your own forum how wrong you are.

Your >>> Chuck has to correct your microphone and Dragon information constantly <<< is a personal attack and you have been warned several times by the forum administrators against this type of behavior. If you want to continue posting on this forum, please discontinue with the personal attacks. You could be re-phrase your statement by saying we occasionally disagree. I'm not always right but neither is Chuck.

 

I'm not sure why you are bringing up Chuck Runquist or NaturallySpeaking and I didn’t notice a posting arguing my noise cancellation results on any other forum but neither Chuck or DNS have anything to do with the laws of microphone physics. My 40 plus years in the recording industry experience simply say otherwise and I believe I probably have more experience than you and Chuck combined in this particular area as I owned, produced and engineered in a recording studio for 15 years. This has nothing to do with NaturallySpeaking. Until you hit the saturation point (referred to as clipping in the music industry), the louder your input volume is, the more noise rejection you will acquire and this is just simple acoustic math.

If I begin to scream now over all the bickering, will I need to create a new microphone profile in DNS to accomodate that ?Super Angry
