I have severe loss in both ears. The Banglajian company has one bte model that provided me with more than sufficient volume capacity and also several other sound quality features. They come with a selection of sizes in ear buds and can be connected with thin or thick tubing. I use my own ear molds as I have larger than normal openings and ear buds won't work well for me. The model is Zif 106and sells for about $125. The company has truly excellent customer service and return policies. They also have a model in the $80 range that also works well. I use this hearing aid as an excellent back up when my main aids are being serviced or repaired.
