Thank you for a comprehensive and informed review. As a nurse with hearing loss ( congenital and worsening) I am looking to purchase my first electronic scope and this has been a big help.

Thank you! I am a severely hearing impaired Respiratory Therapist. My Electromax Stethoscope died and am looking at different options (they don't make this scope anymore). I was between the Littman and the Thinklabs. The amplification of 100X normal scope power is amazing and to hear that the quality of sound is pretty good really helps. No one has either of these scopes to test out. Thank you again!!!

Great review. Clear and informative. Pretty excited to order the one myself.

Thanks for taking the time to do the review. I have Mild to Moderate hearing loss and do well with a Cardiology III. Think I'll stick with it for now.

Jack Hydrick hi could you share if you need to remove your ha s when using your current stethoscope?

Hello, could you please give us an updated review of the Thinklabs One stethoscope. Just to know how it has been since your first review. Thank you in advance

Great review with details and real recording, THX~!

I wish that every review would be like that, what an amazing review, thank you very much for that!

Well done review and product comparison.

Would love to hear a comparison vs an Eko Core (or even Eko Duo). Thinking of either one of these (Thinklabs One, Littman or Eko) and can’t decide!

Great review!, i've always wondered what stethoscope you used. I hope you continue to such reviews, maybe even a comparison between convetional steths

I like the One enough that I'm not sure I could bring myself to do a remotely robust head to head comparison in the hospital of conventional stethoscopes. However, the Littmann cardiology III is the best conventional stethoscope I've previously used, and seems to be the most common among other attending physicians at my institution (not to imply that most popular necessarily equates with being the best).

I use littmann 3200 since 2 years and its better than any other electronic stethoscopes

I enjoyed your stethoscope review. I have had several digital stethoscope and agree with you on the littmann. I bought the Thinklabs one and love it. Your review was spot one.

Great job. Thanks for doing this video!!

Hi! I would like to know if you have ever used a spectrum analyzer app to record the sounds and displaying. In your review, where you used audacity, one can see a phonocardiogram, but it would be interesting to know if seeing the frequencies vs dB on the phone could improve diagnostic accuracy.

so if youre getting a digital signal, couldnt you run it through software to detect anomolies? For instance if the signal has higher frequencies associated with wheezing, it could give an alert.

Excellent review!

I hope you make an updated one of this!

Thank you for this dynamic approach~~

thanks, I really enjoined your review.

Thanks for the great review and hope this product just continues to get better. If they can make bluetooth built into it, it would be more worth the price. I am hard of hearing and wear hearing aids and could love to stream the sounds to them but I cannot afford this nor the bluetooth adapter so I am going to go with the Cardio III like you suggested in your video. See how it goes if I still cannot hear will have to find a way to get this.

Great comprehensive review. Personally, I have used the 3100 for nearly 8 years now, it has never failed me once. I recently went with the ONE, I have had it about 2 months now. The sound clarity is far superior to the 3100. The ear bud cords do seem to get tangled more than I would like, and lastly (for me) after average use the ONE battery was zero just before a shift, it took about 6 hours (connected to a computer USB) to charge. One last note, to add wireless connectivity to the ONE (with decent bass earbuds) is another $200 on top of the cost of the ONE.

Hi Don, thank you for your helpful comments. What do you mean "to add wireless connectivity to the ONE" ? Thinklab has a Bluetooth transmitter for audio wireless connectivity for $50. What do you mean by $200 more?

Thank you for the good review. As a paramedic I will wait with investment on this until there is a better alternative. To have to connect a unit to a recording device is just to much hassle on scene.

What about now, in 2019? Did the Thinklab device get some upgrades? The con's of this device were improved? Is it worthy to get one now?

Do you know if the Thinklabs One would pick up the fetal heartbeat well? I imagine this potentially being a great ultrasound free alternative to using a fetal doppler.

Great objective review! For me as a person who loses lots of pens on wards the small size is actually a disadvantage as it can get misplaced easily. It is much more difficult to lose your bulky oldschool stethoscope. This aside I think that thinklab one is awesome and I'd buy one have I known I'm not gonna lose it soon :/

Vic, thanks for the message. To get the phonocardiogram, I recorded the sounds with the Thinklabs attached to a digital recorder, which saves the audio as a wav file. Then I opened up the wav in an audio-editing program called Audacity, and just took a screen shot. Just takes a minute, but unfortunately, can't do it at the bedside (or anywhere at the VA since they won't let us install outside software!). Let me know if you'd like to borrow the Thinklabs One for a little while - happy to stop by and lend it out for a trial.

I have a question, I have a hearing problem and I'm currently enrolled as a nurse assistant and need to order specialist stethoscope.I need a stethoscope to check B.P and respirations I'm using a traditional stethoscope but having trouble with it.Would you recommend the ThinkLab or stick with the littman 3200?

@StrongMed

Marcos Lugo There are different types of hearing loss which might impact which stethoscope is best. I would recommend trying to find someone who owns each, and test driving them on a few patients (though that may be hard for the Thinklabs since it isn't widely used - at least not yet!). Having said that, if what you are looking for is whichever stethoscope amplifies the sound the most, the Thinklabs One can get much much louder than the Littmann 3200. It's not even close. At it's loudest volume setting, the Littmann doesn't seem all that much louder than the conventional (non-digital) Littmann cardiology III. However, with the Thinklabs, on a 1-10 scale, once the volume gets above about 7-8, it is physically painful to use for a person with normal hearing.

Cheers for a great review. Comment coming 7 years later from post :)

+piyush arora I've used an iPad at the bedside for discussing heart murmurs. The sound quality on the external speakers of the iPad are not good enough for diagnostic purposes, but I think they helped the patient/family accept that there was something abnormal. As I think I mentioned in the video (and if I didn't, I meant to), neither the Thinklabs One nor Littmann 3200 do a great job with reproducing lung sounds. I have no idea why the fidelity seems to be less than heart sounds, unless it's a function of how we unconsciously use the rise and fall of a person's chest to help time lung sounds when listening in real-time, which we aren't able to do on a recording. Having said that, the wheezing of an asthmatic is the least ambiguous of lung abnormalities heard with a stethoscope, so that probably won't be an issue.

So if the littmann quit working properly after 18 months, how long have you used the Thinklabs one steth?

There is also a device you can attach to existing stethescope called Eko Core. Its worth looking at, most people are very dependent on Littman, so the good news is it can attach to your comfortable Littman. You can then upload the data for further analysis, it captures sound in real time so you can see it on your device. Really a great tool. Does anyone have actual in practice experience with the product that is reviewed here?

Great video! I wanted to know the comparison between the Littmann digital stethoscope and the Thinklabs One. I bought the model 3100 one and it was disappointing because it wasnt the right stethoscope for me. I got moderated hearing loss and been struggling for one that connects to my hearing aids. I've been told that Thinklabs One is really, really good. The sound quality is really great they say. It just that i really have to take care of it.

Carlos Wazar I've had other viewers ask me about whether the Thinklabs One can be directly connected to a hearing aid. I honestly don't know, but I've found the company to be very responsive to questions sent via email, and would recommend you ask them about it directly. DEpending on the nature of your hearing loss, you may find that you don't even need to use your hearing aid when using the Thinklabs One - it's maximum volume setting is very loud, much louder than a person with normal hearing could ever tolerate.

+Eric's Medical Lectures +Carlos Wazar I have older model Siemens Pure wireless binaural hearing aids and it looks like they would connect using an additional accessory sold by Siemens with a 35mm input that transmits their proprietary wireless signal to the hearing aids. Newer models do this using a smartphone app as a bridge but something needs to "translate" the wireless signal. The other brands I've seen are similar but things are always changing! I think a part of what everyone is concerned about is the inconvenience of continually removing and reinserting their hearing aids (and potentially losing them!) every time they need to use their stethoscope. Thanks for the review, BTW. I need to start taking a BP manually but the cheap stethoscopes just aren't loud enough for me. Unfortunately both of these are out of my price range. I'm hoping either the new Littmann Classic III or a used Cardiology III will be an acceptable compromise.

Hello A family member has many times ears infection by using "normal" sthetoscopes, I think the Thinklabs model solves this problem if she uses a "external¨ headphone, right? She is in her second year or internal medicine, what else do I need besides the sthetoscope itsef?, the Bluetooth options are for cardiologist only?, there is any model with noise cancelling? Many Thanks RC

+Roberto Calles I haven't encountered anyone before who had problems with recurrent ear infections from stethoscope use (not to say that it can't happen!) Are you sure it's infection and not physical irritation that he/she is experiencing? Or maybe even a contact dermatitis from the material used for the earpieces? The standard Thinklabs One package comes with everything you need, except software and hardware for recording and/or visualizing sounds (if one wants to do this; it's helpful for teaching, but not needed for patient care). To record, you will either need a smartphone or ipad with a compatible recording app. Alternatively, you could use a portable digital recorder (e.g. Zoom H4N), which is what I use, but this is more cumbersome and expensive. Regarding noise cancellation, excessive ambient noise was still a problem for the model I bought and reviewed. I don't know if the company has addressed this better in the 1.5 years since. If not, the best strategy to reduce ambient room noise is good fitting earpieces.

I don't know anything about fixing 3200s - if I did, I would have fixed my own a long time ago! And yes, I definitely recommend the Thinklabs One for hearing impaired clinicians. The amplification is unreal.

Interesting that you have had such a bad experience with the 3200. I have owned mine since 2014 and it has been used hard. I find the noise cancellation to be one of the biggest advantages, especially when working on the side of highways, in aircraft, or in the ED. I have not tried the thinklabs, but I have used several other digital stethoscopes, and too many classic models to count from the cheap isolation stethoscopes to my old master cardiology. For a noisy environment, the 3200 is what I prefer. While I agree there is no need for the 'traditional' shape, it is convenient to throw around your neck while you continue to assess and treat, listen, intubate, then confirm lung sounds again. Not the same with a puck. Much easier to misplace during a chaotic rescue with hydraulic rams and cutters removing car doors while you are in the back seat auscultating lung sounds. Different tools for different environments. Like I said, I have absolutely abused my 3200 and it is still going strong. It works great whether I am working as a nurse, or as a paramedic, and I hear the murmurs I miss with non augmented stethoscopes due to slight hearing loss from years of rescue work. I would like to see improved bluetooth... and the software stinks, but my 3200 is battle proven.

I'm glad you've had more luck with the 3200 than me, and thanks for sharing so viewers appreciate the spectrum of user experience with it! I agree that it would be much easier to lose the Thinklabs One in environments like the field or trauma bays. Luckily 99% of my patient encounters are in relatively calm hospital rooms, so haven't misplaced it (yet).

Thinking about buying one. When connected to a bluetooth device, can the sound be heard "live" by both clinician and patient during the examination?

Is it bluetooth supported device

Very good review! I always wanted to buy a digital stethoscope, I love gadgets/technology. By the other hand, as a med student, I've concluded that it's not a good investment, once I am not going to Cardiology or any Clinical specialization and I can see in your video that the digital ones doesn't offer that much more compered to a regular stethoscope, and costs a bit more! Thanks for the review video!

The problem with the background noise isn't that the One lacks built in noise reduction, it's that it uses a 3.5mm jack. Any real microphone uses XLR or USB connectors, but these would be impossible for this device. Audacity's noise reduction abilities would likely be better than anything they could put into the One. I'm afraid this device is about as good as you're gonna get.

Though you may be right that real-time, digital noise cancellation solutions may not be minaturizable enough to fit inside a stethoscope head (at least not in 2016).

Hi, good review. I decided to buy the Thinklabs after watching your review. I find the earpiece hard to use as it tends to fall out of your ears. I guess I need to by some new earphones. As far as the Litmann, I am on my second which I bought after sending the first one back and then having it break again. Since it was a new model, I was less upset but it gets expensive to keep sending it back and paying for repairs. The new one just stopped working. The display intermittently goes off. I found if I opened the battery compartment and they twisted it back on, the power would restore. I don't know if this is the same problem with yours but it could be. Try taking a Q tip and cleaning the contacts inside the stethoscope where the battery fits in. This so far has corrected the problem. I actually did the cleaning with a pencil eraser that I anserted and spun a few times against the contact but when I get the Q tips, I will clean it further.

I wonder how this device would perform in high noise environments like the back of an ambulance

My 3200 has been excellent for pre-hospital and critical care. I bought it for the noise cancelling, and I like that you can wear it around your neck while assessing and treating. No one is wearing a white coat in the field... and I am not putting my hands in my pockets after they have God only knows what fluids on them. Easy to wipe down the 3200, and easy to put a glove over the diaphragm. :) I am curious about a Chinese version of the Thinklabs... www.alibaba.com/product-detail/Minttihealth-Smartho-Digital-Stethoscope_60738135324.html?spm=a2700.details.deiletai6.10.47ac66e2sl12gq

Your 3200 is probably not working because of dirty contact in the battery compartment, I bought a new one because the first stopped working after I had already paid to fix it once.
