Discretion is priced differently by different sellers, and the only way to see how is to read what each one charges for the model it calls its smallest. Two of the three sellers in this record name such a model explicitly and publish its price, and the gap between them is most of the gap in the market as a whole. This page quotes those figures and describes what the sellers say about the size, without ranking anything or claiming that any device is invisible in any particular ear.

What each seller calls its smallest, and charges for it
MDHearing marks the NEO XS as its smallest model, an in-the-ear design, and publishes it at $297 a pair. Its in-the-ear model with customized sound profiles and smartphone app control, the NEO XS PRO, is $597 a pair. Jabra Enhance describes the Enhance Select M3 as the world's smallest receiver-in-ear hearing aid, gives its dimensions as 1.03 inches long and 2.12 grams, and publishes it at $1,995 a pair, the top of its three-tier list. Audien's list is organized by capability rather than size and its cheapest models, the Atom One at $98 and the Atom Air at $149 a pair, are described as light and comfortable rather than as its smallest.
Size and price do not move together
This is the useful finding and it runs against what most buyers expect. At MDHearing the smallest model is the cheapest thing on the list, at $297 a pair against $397 for its behind-the-ear VOLT 4. At Jabra Enhance the smallest model is the most expensive, at $1,995 against $1,195 for the M1. The two sellers price discretion in opposite directions, because in one list the small model is the simple one and in the other it is the flagship carrying the top capability. A shopper who assumes that smaller costs more, or that smaller costs less, will be wrong at one of these two sellers.
What in-the-ear and receiver-in-ear mean on a price list
The terms are descriptions of where the parts sit and they appear on these lists as product categories, not as a scale of concealment. MDHearing splits its four models into in-the-ear and behind-the-ear and prices across both. Jabra's three are receiver-in-ear, with the electronics behind the ear and a small receiver in the canal on a thin wire. Neither seller claims a device is invisible, and this record does not either: how visible any of them is depends on the ear, the hair and the wearer, which is not something a published price can establish.
What is not on this page
There is no ranking of small hearing aids, no best-of list and no verdict about which of the models named here anyone should buy. This site publishes a price record and no quality ranking, and it states no clinical claim, so it does not advise on which style suits a given degree or shape of hearing loss. That decision belongs with an audiologist, and it is a decision the price list cannot inform.
Questions people ask about invisible smallest hearing aid cost
What is the cheapest smallest model published here?
MDHearing's NEO XS, an in-the-ear model the seller marks as its smallest, at $297 a pair on its own published list.
What is the most expensive?
Jabra Enhance's Enhance Select M3 at $1,995 a pair, which the seller describes as the world's smallest receiver-in-ear hearing aid at 1.03 inches long and 2.12 grams.
Are invisible hearing aids really invisible?
The sellers read here do not use that word about their own products, and neither does this record. They publish dimensions and a category name, and how noticeable a device is in a particular ear is not something a price list can tell anybody.
Are these prices per pair?
Yes. All three sellers in this record publish per pair rather than per aid, which is worth confirming against any figure quoted elsewhere.
