Good mouthpiece for the price

Fits in our Bach trumpet. Has a nice sound and so far so good on no tarnish/peeling/etc.

I have braces so this was a very convenient mouthpiece for me. I bought two and use one for the top and one for the bottom. My teeth are constantly adjusting and this product did not fall apart when I boiled it more than once.

Fantastic instrument for a novice player I would ditch the mouthpiece for higher quality overall very nice playing instrument.

Works good and to my surprise it doesn't give water that plastic taste. Four stars because the clear part of the mouthpiece fell off while I was riding and tried to remove the cap. The mouthpiece got out due to the cap's pressure when being removed and a car went over it. I picked it up, cleaned it, place it again in it's spot and I am now removing and eliminating the cap, problem solved.

The valves were sticky, but a little valve oil fixed that easily. The instrument itself is well constructed; it doesn't appear that any components are shoddy or that the manufacturer cut corners. The sound isn't professional obviously, but it does have a nice sound, and is easy to play. The mouthpiece is fairly run-of-the-mill, but by no means poor quality. Finally, the case is sturdy and well padded.

If you're just starting out, this is perfect. If you're a professional, this is a good rehearsal instrument.

I think this is a nice little harmonica. It's not super professional looking, but it sounds nice from what I can tell. I am just learning to play it, but I have been a singer and bassist for over 20 years, and I have a good ear for things being "in key". The only minor drawback is that the first two holes are a little quiet and harder to blow the air through. But there actually is a "sweet spot" for how to make the sound come out of those two holes, and then it is almost perfect. For the price, I really think this would be hard to beat. I am happy with it.

This is fairly accurate copy of a Denis Wick mouthpiece.  I had the Denis Wick model years ago and this seems pretty close.  The finish is smooth
and the shank fits well in a small shank tenor trombone.  It's a good way to try a mouthpiece, and not pay $70.

It fit great on my 30 year old clarinet, the reed is crappy, but that's OK. worth it to have a new mouthpiece

It's surprisingly good.  Use a good mouthpiece.  I just got it the other day, hoping that the slide smooths out.

The mouthpiece  is exposed and this doesn't make it very hygienic (we also order the small version a that one came with a protective cap- that one gets a 5 star)

It's very good ligature  look nice and fits with any mouthpieces. The prices is good deal.

I received this earpiece a month ago, and I use it daily. The volume is louder than a previous Plantronics earpiece I had, but sometimes there is a bit of a crackly, "clipped" sound when people talk, like the gain is turned up too high.

People on the other end had no difficulty hearing me. That's important!

The on-off switch is difficult to toggle (and oddly, goes the opposite direction of my old one that was replaced by this).

The battery life is excellent.

Overall, I'm pleased, but the sound could be better.

Nice mouthpiece for my alto sax. I am a beginner and switch from YAMAHA 4C to this MP and immediately I can hear the tone change from a very bright sound to a mellow, deep tone which I like. It had more resistance compared to 4C, but with some adjustment I am hook on this MP. I used Vandoren tranditional 2.0 cane reed and it sqeak a lot, then I switch to Rico royal 2.5 still the same. Finally I settle it on Rico placticover 2.5 reed and Rovner versa ligature and it was perfect. No sqeak and the tone was just right. I would give it a 5 stars if not the high price. Afterall it was just a rubber MP not a metal one that can last forever. Cut the price in half then it will be the perfect one.

4 stars on price and function out of the box.

Pros:
Functions well
Low price

Cons:
Cord needs to be a little longer
Cord connection point may be weak (unknown at this point
A larger earpiece would be nice to seal a little better (comes with two that are the same size)

This is my  first experience with a throat mic and it didn't disappoint.  The mic makes you sound a little nasaly, but I understand that is just a function of how the unit picks up sound.  The earpiece sounds surprisingly good.  Where you need to communicate in a noisy environment, this will work great.

It's not super high quality, but for random practice to replace a missing mouth piece, this is a great value. The reed was rather thin, so it was probably a 1. Odds are, you're not buying this for the reed though.

I have been through several of the Plantronics 510 Voyager headsets, not by choice, but because I misplace them - and they are still a great value for the price.  I have been through a lot of other non "loop" earpieces by choice, because I feel like I am placing a metal Q-Tip in my ear.

This one is much more comfortable, and does not sit so tightly in the ear.  It's very light and I have no complaints with the fit and feel.  There are three ear piece sizes to choose from.  I went with the small for a while, then settled on the medium.

The cons I have is the same as one other reviewer - wind noise.  You can't use this outside if the wind is even at 5mph.  One other con I have is sometimes I get a strange "robotic" sounding voice, but it corrects fairly quickly.  One last nit pick, I'd like to be able to get the voice a little louder, but I think that is more on my phone.  However, the 510 was louder.

Overall, very happy with it and would recommend it.

Great mouthpiece, If you follow the directions it stays in place well. I use for Jiu Jitsu and have never had it fall out even on days with a lot of rolling.
