Customer Ratings & Reviews

I was so excited to get these and try them out; afterall, I've used Denon / Marantz receivers and speakers for over a decade with success. Unfortunately, the PerL Pro's are terrible in terms of fitting them to your ears, setting them up in the app, and definitely in terms of performance. Denon is very late to market with these truly-wireless earbuds, so time should have been taken to get it RFT (Right First Time). These are neither fit to be on the market nor worthy of the Denon name. Too little, too late. Open up the box to get the different size tips and pull out the plastic bag they were in (see pic). At this price point, it's a miss. Among many other misses. The silicone tips have circular holes to fit over the tips of the buds. Unfortunately the bud tips are oval. Conceptually, it's easy to pinch the silicone tips and place them over the oval tips of the buds but it isn't easy when there is little silicone to grasp, and I need to push them over the lip of the bud tip to stay in place...and they don't, even when you think you have it, the the silicone tip flies 3 feet away. There are also 2-3 different sizes of wings for a custom fit. The wings do nothing due to poor fit; I'm not certain what ears they are made for. You are supposed to hold the earbuds, put them in, and rotate them, but when you rotate, it doesn't 'catch' anything, and you end up starting/stopping your music five times. After an hour of trying all combinations, nothing worked to acceptably seal my ear with the bud. Which is in turn unfortunate, because a good seal is needed during earbud settup, as the app / earbuds 'map' your ear canal / hearing; see the pictures. The error in the pic about poor seal happened a few times, which will cause anyone's blood to boil, knowing that the mapping of ear canal / hearing is like 1-2 minutes long. To be able to finish settup and listen to music, I pushed the earbuds into my ears to make a seal. That colored circular pink/purple 'mapping' looks fancy, but it is meaningless, as a description of colors and mapping is not given. Regarding mapping, you can select 'Default' or 'Personalized'. By all means go through the mapping, because the 'Default' setting results in a 'tinny' sound with no feeling in the music. Everytime I put them away and re-connected them, I had to go through a 20 second search for the earbuds, and many times, I needed to go into BT settings and select them, to get them to re-connect. You finally get them fitted, set up, connected, and mapped, at which point any positive experience was totally over for me. That was solidified when I listened to music...vocals and especially base were terrible. Nothing but popping and crackling. I understand about the size of the drivers, but several competitors can handle base, one at about half the cost of the Denon PerL Pro's. If the earbuds produced impeccable sound, it barely justifies the settup and mapping process. So these are a total Fail for Denon. The charging is fast via USB Type-C. But the case is poorly designed. The case is relatively small, and the earbuds are held in by a magnet. However, the earbuds are impossible to get out of the case because the magnets are strong and you need a screwdriver of long nail to place into the compartment to get them out.

If I had given a review for this before, this is the latest and most likely the last review for this headphone. The sound is fantastic BUT, and it is a big one, the connection started to randomly glitch out. It is like listening to a scratched up record. It does not matter which device it is connected to. Every now and then, randomly, the sound cuts off as if this was a cable headphone and the cable was not fully seated. It is SUPER ANNOYING!!! The case for it does not charge the left earbud. I clean and clean the connectors very very very gently. Does not matter. It does not fully connect. I have to either press on the ear bud into the case or shake the case after closing the lid. Unfortunately for me these issues have started after the regular return period. So I dont care how good these sound anymore. There are lots of other headphones out there sound also great. The issues I am having to deal with makes these headphones a failed purchase. I would not recommend.

Very poor quality. The headset keeps getting disconnecting and now it doesn't work at all.

The sound quality was amazing but one bud stopped working after 80 days. Denon was quick to respond with some troubleshooting, like charging for 24 hours, but they keep stalling, now that it's obvious they need to be replaced. The contact either stops or they tell me that someone will reach out in 1-2 days with a solution. For this price, why can't I process a replacement? They are outside the return period, but they are also unusable. So I have an expensive paperweight.
