Alternatively you can purchase Comply Smartcore or Sport Pro ear tips that will also help reduce bass and increase clarity. I am using these Comply tips atm on these bad boys; much more comfortable.
TL;DR : Hands down these are the workout versions of WF-1000XM3 earbuds. Durable, water resistant, and a very secure fit with excellent battery life. Same features as XM3s and bassier for an engaging workout. I workout at a noisy private gym that blasts music and the SP-800N cancel out everything for me to focus on my lifts. They have volume controls (customized in the Sony app), good call quality, and an excellent ambient mode. Touch controls are smooth and the touch pad is wide and curved to conform to your index finger. Language voice can be customized and I have these on the Japanese voice pack. The auto play and pause feature upon removal or insertion of the earbuds work smoothly and seamlessly just like the WF-1000XM3. Don't mind the large case since I chuck these in my gym bag and in general they still fit in my pockets fine. Highly recommend, Sony did a great job on them!
Context:
I have owned the Sony WF-1000XM3 earbuds since last year September 2019. I've tried working out with the XM3s and even biked through a rain storm in NYC with them. I used them in the gym to lift weights and have gotten chalk all over them. The XM3s despite not having an official IPX water rating have still held up. Unfortunately I always disliked how they would over time start falling out of my ears. Even with the official Sony Comply Grip foam tips, I would need to adjust them here and there. Then comes these newly released SP-800N.
These SP-800Ns have the wings which is mandatory and what the XM3s should've had. These are amazing, I can now workout, run, or bike without worrying my earbuds will fall. These are just as secure as the Jaybird Vistas I used to own before selling them to a friend. The IP55 water rating is a huge plus. The massive battery, 9 hours with ANC and 13 hours without is amazing.
I now use my Sony WF-1000XM3 purely for commuting on public transit (subway and bus) here in NYC and for premium every day carry audio. These SP-800Ns will serve for the gym and as an excellent backup.
Because these fit better and seal better, I think they end up blocking more noise in the long run. ANC is almost as strong as the XM3s but the secure fit makes up for it. XM3 buds still have the best ANC.
Again, sound signature is bassy which isn't a bad thing. The Sony Headphone Connect App is what makes these one of the best on the market. So many customizable features and full equalizer to tweak the audio to your liking.
Only con is lack of wireless charge so hopefully the XM4s and next year's SP upgrade will include this feature. I don't mind the carrying case being large imo. I throw these in my gym bag and they still fit in my pockets fine. Moreover it's kinda eh you only get one charge with the case. Still at least the buds can go for a long time.
These are a great purchase! Awesome job Sony!
